Структура

Compose — это комбинация 7 идентификаторов групп Maven в androidx . Каждая группа содержит целевой подмножество функций, каждая из которых имеет собственный набор примечаний к выпуску.

В этой таблице описаны группы и ссылки на каждый набор примечаний к выпуску.

Объявление зависимостей

Чтобы добавить зависимость от Compose, вам необходимо добавить в свой проект репозиторий Google Maven. Для получения дополнительной информации прочтите репозиторий Google Maven .

Добавьте зависимости для нужных вам артефактов в файл build.gradle для вашего приложения или модуля:

dependencies {
    implementation "androidx.compose.material:material:1.7.3"
}

android {
    buildFeatures {
        compose true
    }

    composeOptions {
        kotlinCompilerExtensionVersion = "1.5.15"
    }

    kotlinOptions {
        jvmTarget = "1.8"
    }
}

dependencies {
    implementation("androidx.compose.material:material:1.7.3")
}

android {
    buildFeatures {
        compose = true
    }

    composeOptions {
        kotlinCompilerExtensionVersion = "1.5.15"
    }

    kotlinOptions {
        jvmTarget = "1.8"
    }
}

24 августа 2022 г.

androidx.compose.material:material-*:1.3.0-beta01 выпущен. Версия 1.3.0-beta01 содержит эти коммиты.

Поведение нарушение изменения

Максимальная поддерживаемая высота в диалогах и всплывающих окнах была уменьшена до 8DP.

Максимальная поддерживаемая высота для композиционных диалогов и всплывающих окнов была уменьшена с 30dp до 8dp. Это изменение влияет как на материалы, так и пользовательские диалоги и всплывающие окна. Это изменение сделано для смягчения ошибки доступности в версиях Android ниже S, а также для обеспечения того, чтобы службы доступности в этих окнах могли взаимодействовать с контентом внутри диалога или всплывающего окна.

На вас повлияют это изменение только в том случае, если вы создаете пользовательский диалог или всплывающую реализацию с повышением уровня, выше 8DP. Подумайте о том, чтобы снизить высоту диалога или всплывающего окна. Если вам нужно отказаться от этого нового поведения, рассмотрите возможность поднять свой собственный диалог или всплывающее окно с желаемым набором высоты. Это не рекомендуется, так как доступность может быть негативно повлияла, и он находится на разработчике, чтобы обеспечить нижнюю часть диалога или всплывающего окна взаимодействовать и читаемой с помощью служб доступности.

• Добавлен ComposableTarget , ComposableTargetMarker и ComposableOpenTarget , которые позволяют отчетность по времени компиляции, когда композиционная функция называется нацеленным на приложение, которое он не предназначен для использования.

  В большинстве случаев аннотации могут быть выведены с помощью плагина компилятора Compose, поэтому использование этих аннотаций непосредственно должно быть редким. Случаи, которые нельзя вывести, включают создание и использование пользовательских прикладных, абстрактных композиционных функций (таких как методы интерфейса), поля или глобальные переменные, которые являются композиционными лямбдами (выводится локальные переменные и параметры), или при использовании ComposeNode или связанных композиционных функций .

  Для пользовательских приложений композиционные функции, которые вызывает ComposeNode или ReusableComposeNode необходимо добавить аннотацию CompoableTarget для функции и любые типы параметров композиции Lambda. Однако рекомендуется создать аннотацию, которая аннотирована с помощью ComposableTargetMarker , а затем отмеченная аннотация вместо ComposableTarget напрямую. Компонируемая аннотация, помеченная ComposableTargetMarker , эквивалентна ComposbleTarget с полностью квалифицированным именем класса атрибутов в качестве параметра приложения. Для примера использования ComposableTargetMarker см. anroidx.compose.ui.UiComposable . ( I38f11 )

Добавлены правила профиля

Этот релиз добавляет правила профиля к следующим модулям Compose ( i14ed6 ):

• Androidx.compose.animation
• Androidx.compect.animation-Core
• Androidx.compose.foundation
• Androidx.compose.foundation-layout
• Androidx.compes.material
• Androidx.compes.material-Ripple
• Androidx.compose.runtime
• Androidx.compose.ui
• Androidx.compose.ui.geometry
• Androidx.compose.ui.graphics
• Androidx.compose.ui.text
• Androidx.compose.ui.text
• Androidx.compose.ui.unit
• Androidx.compose.ui.util

Что такое правила профиля?

• Правила профиля для библиотеки указываются в текстовом файле baseline-prof.txt расположенном в каталоге src/main или эквивалент. Файл указывает правило на строку, где правило в этом случае является шаблоном для сопоставления методов или классов в библиотеке. Синтаксис для этих правил является суперсетом формата профиля искусства, читаемого на человеку, который используется при использовании adb shell profman --dump-classes-and-methods ... Эти правила принимают одну из двух форм для нацеливания на методы или классы.

• Правило метода будет иметь следующую шаблон:

  <FLAGS><CLASS_DESCRIPTOR>-><METHOD_SIGNATURE>
  

• И правило класса будет иметь следующий шаблон:

  <CLASS_DESCRIPTOR>
  

• Здесь <FLAGS> это один или несколько символов H , S и P , чтобы указать, следует ли пометить этот метод как «горячий», «стартап» или «Post Startup».

• <CLASS_DESCRIPTOR> является дескриптором для класса, которому принадлежит целевой метод. Например, класс androidx.compose.runtime.SlotTable будет иметь дескриптор Landroidx/compose/runtime/SlotTable; .

• <METHOD_SIGNATURE> является подписью метода и включает имя, типы параметров и типы возврата метода. Например, метод fun isPlaced(): Boolean на LayoutNode имеет подпись isPlaced()Z .

• Эти шаблоны могут иметь подстановочные знаки ( ** , * и ? ), Чтобы иметь единое правило, охватывать несколько методов или классов.

Что делают правила?

• Метод, который имеет флаг H указывает, что этот метод является «горячим» методом и должен быть скомпилирован заранее.

• Метод, который имеет флаг S указывает на то, что это метод, который вызывается при запуске, и должен быть скомпилирован заранее, чтобы избежать стоимости компиляции и интерпретации метода во время запуска.

• Метод, который имеет флаг P указывает, что это метод, который называется после запуска.

• Класс, который присутствует в этом файле, указывает на то, что он используется во время запуска и должен быть предварительно выделен в куче, чтобы избежать стоимости загрузки класса.

Как это работает?

• Библиотеки могут определить эти правила, которые будут упакованы в артефакты AAR. Когда затем построен APK, который включает в себя эти артефакты, эти правила объединяются вместе, и объединенные правила используются для создания компактного профиля бинарного искусства, характерного для APK. Затем искусство может использовать этот профиль, когда APK установлен на устройствах, чтобы заранее собрать конкретное подмножество приложения для повышения производительности приложения, особенно первого запуска. Обратите внимание, что это не повлияет на отказываемые приложения.

Исправления ошибок

• Modifier.onGloballyPositioned() был изменен, чтобы сообщить о координатах этого модификатора в цепочке модификатора, а не координаты макета после применения всех модификаторов. Это означает, что теперь упорядочение модификаторов влияет на то, что будут сообщать о координатах. ( IEB67D , B/177926591 )
• Добавлены Readme для существующего каталога материалов Compose. ( If9191 )

• Ripple был мигрирован, чтобы использовать RippleDrawable внутри Android -устройства. Это означает, что анимация Ripple произойдет на renderThread, и поэтому будет гладко, даже если поток пользовательского интерфейса находится под нагрузкой, например, когда навигация между экранами. Это не изменяет поверхность API Ripple, но в результате этого изменения могут быть введены изменения поведения. Чтобы помочь миграции, было добавлено LocalRippleNativeRendering , что было добавлено false значение для этого композиции, чтобы вернуться к предыдущей реализации Ripple внутри CompositionLocalProvider. Этот API будет временным и будет удален в будущем, поэтому, если вы столкнетесь с проблемами, которые заставляют вас использовать этот API, пожалуйста, подайте ошибку . ( I902f8 , b/168777351 , b/183019123 )

• Changed Indication#createIndication() to Indication#rememberUpdatedIndication(InteractionState) and removes InteractionState parameter from IndicationInstance#drawIndication(). IndicationInstance should only be responsible for drawing visual effects, and not launching animations / writing state in response to InteractionState changes. These animations and state writes should happen within rememberUpdatedIndication() instead. The indication parameter in Modifier.indication was also changed to be a required parameter. ( Ic1764 , b/152525426 )

• Moved AlertDialog and DropdownMenu to be Android only for now. Added PopupProperties parameter to DropdownMenu for further configuration of the underlying Popup. ( I9c443 )
• loadFontResource is deprecated. Use fontResource instead. imageResource, loadImageResource, vectorResource, and loadVectorResource are deprecated. Use painterResource instead. ( I6b809 )
• Removed toggle and toggleModifier parameter from DropdownMenu, and renamed dropdownModifier , dropdownOffset and dropdownContent to modifier , offset and content respectively. DropdownMenu now behaves consistently to Popup , where the parent layout is used for the position of the menu. In most cases you can move toggle to be a sibling of DropdownMenu and wrap both in a Box . See the updated sample in the documentation for more information on usage of this API. ( I884fb )

• Selection was moved to foundation. ( I7892b )
• Similarly to how we previously removed state { 0 } composable and now promote usage like remember { mutableStateOf(0) } we are going to remove savedInstanceState { 0 } composable. You should use rememberSaveable { mutableStateOf(0) } instead and it will save and restore automatically if the type used inside the MutableState can be stored in the Bundle. If previously you were passing a custom saver object now you need to use a new overload of rememberSaveable which has stateSaver parameter. The usage will look like this: val holder = rememberSaveable(stateSaver = HolderSaver) { mutableStateOf(Holder(0)) } ( Ib4c26 , b/177338004 )
• Added ProgressBarRangeInfo.Indeterminate to mark indeterminate progress bars for accessibility ( I6fe05 )

AbsoluteRounderCornerShape and AbsoluteCutCornerShape were introduced for the cases when auto-mirroring is not desired. ( I61040 , b/152756983 )

• Changed Tab's text and icon parameters, and BottomNavigationItem's label parameter to be nullable, to better convey the behavior of the component when these parameters are / are not provided, since it affects the size and layout of the component. If you are currently passing emptyContent() to represent no text / icon / label, you should use null instead. ( I57ed4 )

• Renamed contentColorFor color parameter to backgroundColor ( I5bb67 )

• Deprecated TabDefaults and replaced it with TabRowDefaults. ( I0f189 )

• Introduced ColorMatrix API used to modify rgb values of source content Refactored ColorFilter API to be an interface and match the implementation of PathEffect. ( Ica1e8 )

• TransitionDefinition-based Transition has been deprecated ( I0ac57 )
• Initial State in updateTransition is now supported ( Ifd51d )
• WithConstraints was reworked as BoxWithConstraints and moved to foundation.layout. ( I9420b , b/173387208 )

• Deprecate non-suspend scrollBy, remove non-suspend scrollTo

  We now recommend using suspend functions to control scrolling and wait for the scroll to finish. We are deprecating and/or removing the non-suspend versions of these functions as part of this transition. ( Ie9ced )

• Deprecate non-suspend smoothScrollBy We now recommend using suspend functions to control scrolling and wait for the scroll to finish. We are deprecating the non-suspend versions of these functions as part of this transition. ( I12880 )

• Introduced ComposeContentTestRule , which extends ComposeTestRule and defines setContent , which has been removed from ComposeTestRule . Added a factory method createEmptyComposeRule() that returns a ComposeTestRule and does not launch an Activity for you. Use this when you want to launch your Activity during your test, eg using ActivityScenario.launch ( I9d782 , b/174472899 )

• The ripple used in Button and FloatingActionButton can no longer be customized by providing a new Indication through AmbientIndication - this was never intended to be a way to customize these components and this now makes these components consistent with other Material components. To customize ripples across an application, see RippleTheme. ( I546c5 )

• animateAsState is now animateFooAsState, where Foo is the type of the variable being animated. eg Float, Dp, Offset, etc ( Ie7e25 )

• BasicTextField received a new parameter called decorationBox . It allows to add the decorations like icons, placeholder, label and similar to the text field and increase the hit target area of it. ( I16996 )

• AnimatedFloat.fling that accepts FlingConfig has been removed. Please use suspend Animatable.animateDecay instead. ( I4659b , b/177457083 )

• clickable, toggleable and selectable can be created outside of composition now ( I0a130 , b/172938345 , b/175294473 )

• Easing has been changed to a functional interface ( Ib14e5 )

• ScrollableColumn/Row were deprecated. Using ScrollableColumn is less efficient comparing to LazyColumn when you have a large scrolling content because with LazyColumn we can only compose/measure/draw visible elements. To prevent users from going inefficient way we decided to deprecate ScrollableColumn and ScrollableRow and promote usages of LazyColumn and LazyRow instead. Users can still decide they don't need the lazy behaviour and use the modifiers directly like this: Column(Modifier.verticalScroll(rememberScrollState())) ( Ib976b , b/170468083 )

• New items(count: Int) factory method for scope of LazyColumn/LazyRow/LazyVerticalGrid. items(items: List) and itemsIndexed(items: List) are now extension functions so you have to manually import them when used. New extension overloads for Arrays: items(items: Array) and itemsIndexed(Array) ( I803fc , b/175562574 )

• Removed experimental monotonicFrameAnimationClockOf methods ( Ib753f , b/170708374 )

• Moved nativeClass to ui module and made it internal. Updated usages of nativeClass in equals implementations to use 'is MyClass' instead. ( I4f734 )

Исправления ошибок

• Added support for disabled and read-only text fields ( I35279 , b/171040474 , b/166478534 )
• animate() is now replaced with animateAsState() , which returns a State<T> instead of T . This allows better performance, as the invalidation scope can be narrowed down to where the State value is read. ( Ib179e )
• Add Semantics role API and add Role as a parameter to clickable, selectable and toggleable SemanticsModifier. Changed Modifier.progressSemantics so that Slider can also use it. ( I216cd )

Version 1.0.0-alpha09

16 декабря 2020 г.

androidx.compose.material:material-*:1.0.0-alpha09 is released. Version 1.0.0-alpha09 contains these commits.

Изменения API

• Renamed *Constants objects such as ButtonConstants to end with Defaults instead, such as ButtonDefaults. Also removes unnecessary default prefixes from properties in these new objects. ( Ibb915 , b/159982740 )

• Compose supports property getters that can make composable invocations. Support for this is not going away, but the syntax for declaring a property getter as being @Composable is changing.

  The now-deprecated syntax for doing this was by annotating the property itself:

      @Composable val someProperty: Int get() = ...
  

  The now-correct syntax for doing this is by annotating the getter of the property:

     val someProperty: Int @Composable get() = ...
  

  Both syntaxes will work for some time, but the former deprecated syntax will eventually become a compile error. ( Id9197 )

• Added androidx.compose.material:material-ripple library containing ripple APIs to allow building interactive components without needing the rest of the Material library. rememberRippleIndication has been deprecated and replaced with rememberRipple. ( Ibdf11 )

Исправления ошибок

• Lambdas in offset modifiers now return IntOffset rather than Float. ( Ic9ee5 , b/174137212 , b/174146755 )

• Refactored ShaderBrush to lazily create a shader instance when sizing information of the drawing environment is available. This is useful to define gradients that occupy the full drawing bounds of a composable at composition time, without having to implement custom DrawModifier implementations.

  Deprecated gradient function constructor APIs in favor of factory methods on a Gradient object. ( I511fc , b/173066799 )

• Modifier.focusObserver is deprecated. Use Modifier.onFocusChanged or Modifier.onFocusEvent instead ( I30f17 , b/168511863 , b/168511484 )

• Moved DrawModifier APIs from the androidx.compose.ui package to the androidx.compose.ui.draw package. Created DrawModifierDeprecated.kt file to include typealiases/helper methods to assist with the migration from the deprecated to the current APIs. ( Id6044 , b/173834241 )
• Renamed Modifier.drawLayer to Modifier.graphicsLayer Also updated related classes to GraphicsLayer as per API feedback. ( I0bd29 , b/173834241 )

• Updated TextFieldValue API
  • made TextFieldValue.composition readonly
  • removed exception thrown for invalid selection range ( I4a675 , b/172239032 )
• Added a new Modifier.drawLayer() overload. It takes a lambda block on a new GraphicsLayerScope where you define the layer parameters in a way which allows to skip recomposition and relayout when the state change happens. DrawLayerModifier is now internal in preparation to migrating its logic into placeable.placeWithLayer() method of LayoutModifier ( I15e9f , b/173030831 )
• Deprecated Ambients named with Ambient as their suffix, and replaced them with new properties prefixed with Ambient, following other Ambients and Compose API guidelines. ( I33440 )

Изменения API

• Emphasis has been deprecated and replaced with AmbientContentAlpha. AmbientContentAlpha is a simpler abstraction that represents the preferred content alpha for part of the hierarchy, similar to how AmbientContentColor represents the preferred content color. Text and Icon now consume the current value from AmbientContentAlpha by default, and you can manually do: color.copy(alpha = AmbientContentAlpha.current) to have the same effect in your components. Instead of using ProvideEmphasis, you can just directly provide a value through AmbientContentAlpha, and use the new default levels in ContentAlpha to replace the old EmphasisLevels. ( Idf03e , b/159017896 )
• Adds androidx.compose.material.AmbientContentColor to replace androidx.compose.foundation.AmbientContentColor ( I84f7b , b/172067770 )
• Adds androidx.compose.material.Text to replace androidx.compose.foundation.Text as a high level, themeable Text component. For a basic text component that does not consume color / text style from the theme, use BasicText. ( Ie6ae0 )
• Added maxLines to TextFields ( Ib2a5b )
• Update TextFields to accept KeyboardOptions ( Ida7f3 )
• Surface now uses the absolute (total) elevation when calculating elevation overlays, so a Surface nested in another Surface will use the combined elevation to draw the overlay. ( I7bd2b , b/171031040 )

Исправления ошибок

• captureToBitmap moved to captureToImage . ( I86385 )
• The foundation AmbientTextStyle, ProvideTextStyle, and AmbientContentColor have been deprecated. Instead use the new versions available in the Material library. For non-Material applications, you should instead create your own design system specific theming ambients that can be consumed in your own components. ( I74acc , b/172067770 )
• foundation.Text has been deprecated and replaced with material.Text. For a basic, unopinionated text API that does not consume values from a theme, see androidx.compose.foundation.BasicText. ( If64cb )
• Rename KeyboardOptions as ImeOptions ( I82f36 )
• Moved KeyboardType and ImeAction into KeyboardOptions ( I910ce )
• BaseTextField has been deprecated. Use BasicTextField instead. ( I896eb )
• ExperimentalSubcomposeLayoutApi annotation was removed. SubcomposeLayout can now be used without adding @OptIn ( I708ad )
• FirstBaseline and LastBaseline were moved to androidx.compose.ui.layout package ( Ied2e7 )
• Updated Icon API to take in Color.Unspecified as a possible tint color which will draw the provided asset or painter without a ColorFilter. Previously attempts to ignore tinting with Color.Unspecified would tint with a transparent color ending up with nothing rendered at all. ( I049e2 , b/171624632 )
• relativePaddingFrom was renamed to paddingFrom. The paddingFromBaseline modifier was added, as convenience for specifying distances from layout bounds to text baselines. ( I0440a , b/170633813 )
• LaunchedTask was renamed to LaunchedEffect for consistency with the SideEffect and DisposableEffect APIs. LaunchedEffect with no subject params is not permitted in order to encourage best practices. ( Ifd3d4 )
• MeasureResult was moved out of MeasureScope. ( Ibf96d , b/171184002 )
• Several layout related symbols were moved from androidx.compose.ui to androidx.compose.layout.ui. ( I0fa98 , b/170475424 )

androidx.compose.material:material:1.0.0-alpha06 , androidx.compose.material:material-icons-core:1.0.0-alpha06 , and androidx.compose.material:material-icons-extended:1.0.0-alpha06 are released. Version 1.0.0-alpha06 contains these commits.

Изменения API

• androidx.compose.foundation.Icon has been moved to androidx.compose.material.Icon. You can also use the Image component / Modifier.paint() with a Painter if you do not want to use the Material library. ( I9f622 )
• Adds FloatingActionButtonElevation to represent elevation used by FABs in different states. See FloatingActionButtonConstants.defaultElevation() for the default implementation ( I2d4f5 )
• Adds SwitchColors interface to represent colors used by a Switch in different states. See SwitchConstants.defaultColors to customize these colors. ( I93805 )
• Adds ButtonElevation and ButtonColors interfaces to represent elevation and colors used by buttons in different states. See the default functions in ButtonConstants to customize these parameters. ( Ic5b7b )
• Adds RadioButtonColors interface to represent colors used by a RadioButton in different states. See RadioButtonConstants.defaultColors() to customize the colors used in different states. ( I74130 )
• Adds CheckboxColors interface to represent colors used by a checkbox in different states. See CheckboxConstants.defaultColors() to customize the colors used in different states. ( I7dbdb )

Исправления ошибок

• Material components do not set the elevation as zIndex anymore. Which means that within the same parent the child with larger shadow size will not be drawn on top of the child with the smaller one automatically. If you still need such behavior please set Modifier.zIndex() manually where needed ( I70417 , b/170623932 )
• Deprecate VectorPainter in favor of rememberVectorPainter to better indicate that the composable API internally leverages 'remember' to persist data across compositions. ( Ifda43 )
• Enable transitions in ComposeTestRule; remove option to enable the blinking cursor from ComposeTestRule. ( If0de3 )
• Added single line keyboard option to CoreTextField ( I72e6d )
• Renamed Radius API to CornerRadius to better express how it is used throughout Compose. Updated documentation to indicate that negative corner radii are clamped to zero. ( I130c7 , b/168762961 )
• Refactored DrawScope and ContentDrawScope to be interfaces instead of abstract classes
  • Created CanvasDrawScope implementation of DrawScope
  • Refactored implementations of DrawScope to use CanvasScope instead
  • Created DrawContext to wrap dependencies for DrawScope
  • Removed deprecated methods on DrawScope ( I56f5e )
• Box was made an inline function. ( Ibce0c , b/155056091 )

Изменения API

• Popups and dialogs now inherit FLAG_SECURE from parent Window. Also added option to configure this explicitly ( I64966 , b/143778148 , b/143778149 )
• Modifier.swipeable has 56.dp thresholds for states by default now ( Iab825 , b/168610267 )
• all scaffold states marked as @Stable. drawerGesturesEnabled in ScaffoldState moved to Scaffold itself. ( I36645 , b/168297016 )
• Removes nullable type from Scaffold lambda parameters, you can use emptyContent() to represent no content for a given parameter. ( I2b318 , b/157633857 , b/158551084 )

• Deprecates contentColor() and currentTextStyle() APIs, and replaces them with AmbientContentColor and AmbientTextStyle ambients respectively. You can access the current value by using .current on the ambient property, as with any other ambient. This was change was made for consistency and to avoid having multiple ways to accomplish the same thing. Additionally renames some ambient properties to better describe their purpose as follows:

  • ContentColorAmbient -> AmbientContentColor
  • TextStyleAmbient -> AmbientTextStyle
  • IndicationAmbient -> AmbientIndication
  • EmphasisAmbient -> AmbientEmphasisLevels
  • RippleThemeAmbient -> AmbientRippleTheme ( I37b6d )

• Adds AmbientElevationOverlay, allowing customizing / disabling the default elevation overlay applied to Surfaces in dark theme. ( I5b74d )

Исправления ошибок

• As part of the standardization of sentinel values for inline classes, rename Color.Unset to Color.Unspecified for consistency with other inline classes ( I97611 , b/169797763 )
• TextOverflow.None is introduced. When overflow is None, Text won't handle overflow anymore, and it will report its actual size to LayoutNode. ( I175c9 , b/158830170 )
• launchInComposition renamed to LaunchedTask to match Compose API guidelines ( I99a8e )
• OnPositionedModifier is renamed to OnGloballyPositionedModifier and onPositioned() is renamed to onGloballyPositioned(). ( I587e8 , b/169083903 )

  • ( I8f5c7 , b/168762961 )
• foundation.Box was deprecated. Please use foundation.layout.Box instead. ( Ie5950 , b/167680279 )
• Stack was renamed to Box. The previously existing Box will be deprecated in favor of the new Box in compose.foundation.layout. The behavior of the new Box is to stack children one on top of another when it has multiple children - this is different from the previous Box, which was behaving similar to a Column. ( I94893 , b/167680279 )
• Box decoration parameters have been deprecated. If you want to have decorations/padding on your box, use Modifiers instead (Modifier.background, Modifier.border, Modifier.padding) ( Ibae92 , b/167680279 )

  • Removed Rect.join and Rect.expandToInclude
  • Created overload for Rect.translate(offset) and deprecated Rect.shift
  • ( If086a , b/167737376 )
• We prevented static imports of contents of layout scopes (eg alignWithSiblings in RowScope). The explicit scope alternative should be used instead: with(RowScope) { Modifier.alignWithSiblings(FirstBaseline) } . ( I216be , b/166760797 )

Изменения API

• Renames BottomNavigationItem 's onSelect parameter to onClick ( I91925 , b/161809324 )
• Adds InteractionState parameter to BottomNavigationItem and Tab, allowing hoisting this state and adjusting how the component appears in different states. ( Ia3e9e , b/168025711 )
• Removes disabledBackgroundColor and disabledContentColor parameters from buttons. You should instead use the new default color functions inside ButtonConstants. If you are already setting contentColor / backgroundColor explicitly, you should instead use these default functions and customize some / all of the parameters to avoid overwriting the color for both enabled / disabled states. ( If9b52 )
• Textfield's background color does not implicitly apply transparency alpha anymore. Instead, any color provided through the backgroundColor parameter will be applied directly. ( Iecee9 , b/167951441 )
• InnerPadding was renamed to PaddingValues. ( I195f1 , b/167389171 )
• The params resistanceFactorAtMin and resistanceFactorAtMax in Modifier.swipeable were replaced with a single resistance param. A new defaultResistanceConfig method was added in SwipeableConstants . ( I54238 )
• Adds animated stateful elevation support for Button and FloatingActionButton. The elevation now animates between default and pressed states. To customize the elevation between states, please use ButtonConstants.defaultAnimatedElevation() and FloatingActionButtonConstants.defaultAnimatedElevation() instead of setting a flat Dp value in all cases. ( I37925 )
• Label became an optional parameter inside TextField and OutlinedTextField ( I267f6 , b/162234081 )

Исправления ошибок

• Global testing functions such as onNode or waitForIdle are now deprecated, please migrate to their new counterparts that are defined on ComposeTestRule ( I7f45a )

• Snackbar support with positioning and proper queueing has been added. Access it via SnackbarHostState.showSnackbar suspend function. Кроме того:
  • SnackbarHost components has been added. It hosts Snackbars based on the state and is responsible for transition between snackbars.
  • SnackbarHostState has been added to allow for control over snackbars, snackbars hosts and to decouple it from the ScaffoldState. you can access this state via scaffoldState.snackbarHostState as well.
  • Snackbar overload has been added to support common interface between snackbarHostState and snackbars itself. ( I79aaa )
• Adds enabled parameter to IconButton, and reorders parameters in IconToggleButton ( I0a941 , b/161809385 , b/161807956 )

• Renames and reorders some parameters in Tab for consistency with other APIs ( Ia2d12 , b/161807532 )
• Splits TabRow into TabRow and ScrollableTabRow, removing isScrollable from TabRow. Also exposes edgePadding in ScrollableTabRow, which allows controlling the free space before / after the tabs. ( I583e8 , b/161809544 )
• The TabRow object has been removed, replacing it with TabConstants. TabRow.TabPosition has moved to be top level (TabPosition), and indicatorContainer has been renamed to indicator . See the samples and documentation for detailed information on how to use the updated API, and defaults. ( I54d45 , b/161809544 )
• The thresholds param in Modifier.swipeable was tweaked; it now takes a pair of states (of type T) and returns the threshold between them in the form of a ThresholdConfig. A param dismissThresholds was added to SwipeToDismiss, which is a lambda (DismissDirection) -> ThresholdConfig. ( Ie1080 )
• Slider has more colors for granular customization ( I73e64 , b/161810475 )

Изменения API

• Colors is now a final class instead of an interface. Instead of extending and providing a custom implementation, you should create a new ambient for your custom theme object, and access the theme object through the new ambient in your components, similar to how MaterialTheme works internally. ( Ibae84 )
• Renamed ColorPalette to Colors, to better map to the Material color system and remove confusion over ColorPalette being a 'generic' theming object, as opposed to being a specific implementation of the Material color system. Additionally renames lightColorPalette and darkColorPalette to lightColors and darkColors respectively. ( I9e976 , b/161812111 )
• Renames BottomNavigationItem's text parameter to label , onSelected to onSelect , activeColor to selectedContentColor , inactiveColor to unselectedContentColor and updates parameter ordering to match guidelines. ( Icb605 , b/161809324 )

Version 0.1.0-dev15

22 июля 2020 г.

androidx.compose.material:material:0.1.0-dev15 , androidx.compose.material:material-icons-core:0.1.0-dev15 , and androidx.compose.material:material-icons-extended:0.1.0-dev15 are released. Version 0.1.0-dev15 contains these commits.

Dependencies Update

• To use the 0.1.0-dev15 version of Compose, you will need to update your dependencies according to the new code snippets shown above in Declaring dependencies .

Изменения API

• @Model annotation is now deprecated. Use state and mutableStateOf as alternatives. This deprecation decision was reached after much careful discussion.

  Обоснование

  Rationale includes but is not limited to:

  • Reduces API surface area and concepts we need to teach
  • More closely aligns with other comparable toolkits (Swift UI, React, Flutter)
  • Reversible decision. We can always bring @Model back later.
  • Removes corner-case usage and difficult to answer questions about configuring @Model as things we need to handle
  • @Model data classes, equals, hashcode, etc.
  • How do I have some properties “observed” and others not?
  • How do I specify structural vs. referential equality to be used in observation?
  • Reduces “magic” in the system. Would reduce the likelihood of someone assuming system was smarter than it is (ie, it knowing how to diff a list)
  • Makes the granularity of observation more intuitive.
  • Improves refactorability from variable -> property on class
  • Potentially opens up possibilities to do hand-crafted State-specific optimizations
  • More closely aligns with the rest of the ecosystem and reduces ambiguity towards immutable or us “embracing mutable state”

  Migration Notes

  Almost all existing usages of @Model are fairly trivially transformed in one of two ways. The example below has a @Model class with two properties just for the sake of example, and has it being used in a composable.

  @Model class Position(
   var x: Int,
   var y: Int
  )
  
  @Composable fun Example() {
   var p = remember { Position(0, 0) }
   PositionChanger(
     position=p,
     onXChange={ p.x = it }
     onYChange={ p.y = it }
   )
  }
  

  Alternative 1: Use State<OriginalClass> and create copies.

  This approach is made easier with Kotlin's data classes. Essentially, make all previously var properties into val properties of a data class, and then use state instead of remember , and assign the state value to cloned copies of the original using the data class copy(...) convenience method.

  It's important to note that this approach only works when the only mutations to that class were done in the same scope that the State instance is created. If the class is internally mutating itself outside of the scope of usage, and you are relying on the observation of that, then the next approach is the one you will want to use.

  data class Position(
   val x: Int,
   val y: Int
  )
  
  @Composable fun Example() {
   var p by state { Position(0, 0) }
   PositionChanger(
     position=p,
     onXChange={ p = p.copy(x=it) }
     onYChange={ p = p.copy(y=it) }
   )
  }
  

  Alternative 2: Use mutableStateOf and property delegates

  This approach is made easier with Kotlin's property delegates and the mutableStateOf API which allows you to create MutableState instances outside of composition. Essentially, replace all var properties of the original class with var properties with mutableStateOf as their property delegate. This has the advantage that the usage of the class will not change at all, only the internal implementation of it. The behavior is not completely identical to the original example though, as each property is now observed/subscribed to individually, so the recompositions you see after this refactor could be more narrow (a good thing).

  class Position(x: Int, y: Int) {
   var x by mutableStateOf(x)
   var y by mutableStateOf(y)
  }
  
  // source of Example is identical to original
  @Composable fun Example() {
   var p = remember { Position(0, 0) }
   PositionChanger(
     position=p,
     onXChange={ p.x = it }
     onYChange={ p.y = it }

• onFocusChange callback in text fields renamed to onFocusChanged ( Ida4a1 )

• Added thresholds param in stateDraggable to specify thresholds between anchors. This was used to set a 56dp threshold in bottom drawer. Also BottomDrawerLayout now uses a separate BottomDrawerState enum. ( I533fa )

• Removes previously deprecated Modifier.ripple. Clickable now uses ripple as the default indication (if you have a MaterialTheme {} set in your application) so in most cases you can just use clickable and get ripple indication for free. If you need to customize the color / size / bounded parameter for the ripple, you can manually create a RippleIndication and pass it to clickable as the indication parameter. ( I663b2 , b/155375067 )

• Removed deprecated override of FilledTextField composable ( I7f8f8 )

• Rename Button object (containing the defaults used by Button function) to ButtonConstants ( I7c5f7 , b/159687878 )

• Replaced usage of IntPx with Int. Replaced IntPxPosition with IntOffset. Replaced IntPxSize with IntSize. ( Ib7b44 )

• In order to consolidate the number of classes used to represent sizing information, standardize on usage of the Size class instead of PxSize. This provides the benefits of an inline class to leverage a long to pack 2 float values to represent width and height represented as floats. ( Ic0191 )

• Deprecates Modifier.ripple. Clickable now uses ripple as the default indication (if you have a MaterialTheme {} set in your application) so in most cases you can just use clickable and get ripple indication for free. If you need to customize the color / size / bounded parameter for the ripple, you can manually create a RippleIndication and pass it to clickable as the indication parameter. ( I101cd , b/155375067 )

• Scaffold API has been reworked: few parameters changed their name, added new parameters for better customization. Added getter to query sizes of Fab, TopBar and BottomBar ( I0e7ce )

• Consolidated CanvasScope implementations so there is now just DrawScope and ContentDrawScope Renamed CanvasScope to DrawScope. Updated DrawScope to implement Density interface and provide LayoutDirection Deleted DrawScope subclass in ContentDrawScope Painter and PainterModifier have been updated to no longer maintain an RTL property themselves as DrawScope provides this already without manually providing it ( I1798e )

• Renames Emphasis.emphasize() to Emphasis.applyEmphasis() ( Iceebe )

• Disabled buttons now visually follows the Material Design specification ( I47dcb , b/155076924 )

• FilledTextField gets ime action, visual transformation and keyboard type support ( I1f9cf , b/155075201 )

• Adds strokeWidth parameter to CircularProgressIndicator to customize the stroke size. To change the stroke size (height) of a LinearProgressIndicator, you can use Modifier.preferredHeight() or another size modifier. ( Icea16 , b/154919081 )

• Adds strokeWidth parameter to CircularProgressIndicator to customize the stroke size. To change the stroke size (height) of a LinearProgressIndicator, you can use Modifier.preferredHeight() or another size modifier. ( Icea16 , b/154919081 )

• Added slot API for trailing and leading icons in the FilledTextField and handling of the error state ( Ic12e0 )

• FAB's and Extended FAB's default color has been changed to MaterialTheme.colors.secondary. ( I3b9b9 , b/154118816 )

• Replaced all nullable Color uses in API with non-nullable and use Color.Unset instead of null ( Iabaa7 )

• Renamed EdgeInsets to InnerPadding. Renamed innerPadding parameter of Material Buttons to paddding. ( I66165 )

• Slider is now stateless. Users will need to pass and update state by themselves, just like in any other control. ( Ia00aa )

• Added Material Design implementation of Filled Text Field ( Ic75cd )

• Added modifier param to ListItem and reordered params to promote trailing lambda body ( I66e21 )

• Adds defaultFontFamily constructor parameter to Typography, allowing specifying the default font family that will be used for any provided TextStyles that do not have a family set. ( I89d07 )

• Temporarily removed Material Data Tables from the API surface. ( Iaea61 )

• Renamed paramaters in Divider composable ( Ic4373 )

• children ( Ia6d19 )

• Removes MaterialTheme.emphasisLevels, instead use EmphasisAmbient.current to retrieve the emphasis levels ( Ib5e40 )

• Shape theming system is updated according to the Material design specification. Now you can provide small, medium and large shapes to be used by most of the components ( Ifb4d1 )

• Changed MaterialTheme APIs such as MaterialTheme.colors(), MaterialTheme.typography() to be properties instead of functions. Remove parentheses from existing calls, no behavioral change is expected. ( I3565a )

• Refactored FloatingActionButton APIs to accept composable lambdas instead of primitives. See updated samples for usage information. ( I00622 )

• add enabled param to Checkbox, Switch and Toggleable ( I41c16 )

• Ripple is now a Modifier. While Clickable is not yet converted the recommended usage is Clickable(onClick = { ... }, modifier = ripple()) ( Ie5200 , b/151331852 , b/150060763 )

• Surface and Card were moved from androidx.ui.material.surface to androidx.ui.material ( I88a6d , b/150863888 )

• Button, FloatingActionButton and Clickable now have a separate enabled param. Some of the params on Button were renamed or reordered. ( I54b5a )

• Renamed Image to ImageAsset to better differentiate the difference between the Image data and the upcoming Image composable used to participate in layout and draw content. _Body:Created extension method on android.graphics.Bitmap, Bitmap.asImageAsset(), to create an instance of an ImageAsset useful for combining traditional Android application development with the compose framework ( Id5bbd )

• Removed Snackbar API with String parameters in favour of using the overload that accepts composable lambdas. See updated samples for usage information ( I55f80 )

• Refactored Tab APIs to accept text and icon lambdas, ( Ia057e )

• Added BottomNavigation component, see the docs and samples for usage information ( I731a0 )

• Added Icon, IconButton and IconToggleButton, removing AppBarIcon. You can directly replace existing usages of AppBarIcon with IconButton, and they will now have the correct touch target. See the samples for usage information, and see Icons for the provided Material Icons you can use directly with these components. ( I96849 )

• Replaced ButtonStyle with distinct functions and removed text (string) overload. See updated samples for usage information. ( If63ab , b/146478620 , b/146482131 )

• rename Border modifier to DrawBorder ( I8ffcc )

• LayoutCoordinates no longer has a position property. The position property does not make sense when considering LayoutModifiers, rotation, or scaling. Instead, developers should use parentCoordinates and childToLocal() to calculate the transform from one LayoutCoordinate to another.

  LayoutCoordinates uses IntPxSize for the size property instead of PxSize. Layouts use integer pixel sizes for layouts, so all layout sizes should use integers and not floating point values. ( I9367b )

• Breaking changes to the ambients API. See log and Ambient<T> documentation for details ( I4c7ee , b/143769776 )

• Scaffold material component has been added. Scaffold implements ( I7731b )

• VerticalScroller and HoriziontalScroller have been deprecated. Use ScrollableColumn and ScrollableRow for build-in experience with Column/Row behaviour and parameters, or Modifier.verticalScroll and Modifier.horizontalScroll on your own element. Similarly, ScrollerPosition has been deprecated in favor of ScrollState' ( I400ce , b/157225838 , b/149460415 , b/154105299 )

• Several testing APIs were renamed to be more intuitive. All findXYZ APIs were renamed to onNodeXYZ. All doXYZ APIs were renamed to performXYZ. ( I7f164 )
• Transition API has been changed to return a TransitionState instead of passing the TransitionState to children. This makes the API more consistent with animate() APIs. ( I24e38 )
• An IntBounds unit class has been added, representing integer pixel bounds from layout. The API of PopupPositionProvider has been updated to use it. ( I0d8d0 , b/159596546 )
• A new optional flag useUnmergedTree was added to test finders. ( I2ce48 )
• Removed obsolete size testing APIs. ( Iba0a0 )
• Removed Shader inline class that wrapped the NativeShader expect class Renamed NativeShader to Shader. The wrapped Shader inline class did not add anything valuable to the API surface and was an inline class, so use the NativeShader class directly. ( I25e4d )
• Popups, Dialogs and Menus are now inheriting the contextual MaterialTheme ( Ia3665 , b/156527485 )
• Material DropdownMenu are now scrollable. ( Ide699 )
• Removed layout direction parameter from the measure block of the Layout() function. Layout direction is however available inside the callback through the measure scope object ( Ic7d9d )
• Use AnimationSpec instead of AnimationBuilder in the top level APIs to clarify the concept of static animation specification -Improve the transition DSL by removing the lambda requirement for creating AnimationSpecs such as tween, spring. They instead take constructor params directly. -Improve the overall ease of use of AnimationSpec opening up constructors instead of relying on builders -Change the duration and delay for KeyFrames and Tween to Int. This eliminates unnecessary type casts and method overloading (for supporting both Long and Int). ( Ica0b4 )
• Switch now appears in a disabled state when enabled is set to false ( If4624 , b/155941869 , b/159331694 )
• Modifier.tag was renamed to Modifier.layoutId, to avoid confusion with Modifier.testTag. ( I995f0 )
• Alignment line Int positions returned from Placeable#get(AlignmentLine) are now non-null. If the queried alignment line is missing, AlignmentLine.Unspecified will be returned. ( I896c5 , b/158134875 )

• Refactored Radius class to be an inline class. Removed companion creation methods in favor of function constructor with default parameter to have the radius along the y-axis match that of the mandatory x-axis radius parameter.

  Updated DrawScope.drawRoundRect to consume a single Radius parameter instead of 2 separate float values for the radius along the x and y axis ( I46d1b )

• In order to consolidate the number of classes used to represent positioning information, standardize on usage of the Offset class instead of PxPosition. This provides the benefits of an inline class to leverage a long to pack 2 float values to represent x and y offsets represented as floats. ( I3ad98 )

• Replaced usage of Px class in various compose classes as part of the large refactoring effort to only rely on Dp and primitive types for pixel parameters. Deleted Px class in its entirety ( I3ff33 )

• Toggleable component has been deprecated. Use Modifier.toggleable instead ( I35220 , b/157642842 )

• Replaced usage of Px class in various compose classes as part of the large refactoring effort to only rely on Dp and primitive types for pixel parameters ( I086f4 )

• Replaced usage of Px class in various compose classes as part of the large refactoring effort to only rely on Dp and primitive types for pixel parameters ( I97a5a )

• Fixed onClick not being invoked for DropdonMenuItems. ( I3998b , b/157673259 )

• MutuallyExclusiveSetItem has been deprecated. Use Modifier.selectable instead. ( I02b47 , b/157642842 )

• Modifier.semantics has been undeprecated to allow usages for high level components. ( I4cfdc )

• DrawLayer modifiers api has been changed: outlineShape renamed to shape and has the RectangleShape default value and now non-nullable; clipToOutline renamed to clip; clipToBounds removed as it is the same as clip == true with RectangleShape ( I7ef11 , b/155075735 )

• Updated higher level compose APIs that expose a Canvas to expose CanvasScope instead. This removes the need for consumers to maintain their own Paint objects. For consumers that still require access to a Canvas they can use the drawCanvas extension method which provides a callback to issue drawing commands with the underlying Canvas. ( I80afd )

• AlignmentLineOffset composable is deprecated, please use relativePaddingFrom() modifier instead. CenterAlignmentLine composable is removed. ( I60107 )

• WithConstraints trailing lambda API has been changed. Now instead of two params it has a receiver scope which in addition to constraints and layoutDirection provides minWidth, maxWidth, minHeight and maxHeight properties in Dp ( I91b9a , b/149979702 )

• Added defaultMinSizeConstraints layout modifier, which sets size constraints to the wrapped layout only when the incoming corresponding constraints are unspecified (0 for min constraints and infinity for max constraints). ( I311ea , b/150460257 )

• FocusManagerAmbient is removed. Use FocusModifier.requestFocus to obtain focus. ( Ic4826 )

• Created CanvasScope API that wraps a Canvas object to expose a stateless, declarative drawing API surface. Transformations are contained within their own receiver scope and sizing information is also scoped to corresponding inset bounds. It does not require a consumer to maintain its own Paint state object for configuring drawing operations.

  Added CanvasScopeSample as well as updated the demo app to include a declarative graphics demo ( Ifd86d )

• Add cursor color customisation to the TextField ( I6e33f )

• TextFieldValue used with TextField can now be survive activity recreation when used like this: var text by savedInstanceState(saver = TextFieldValue.Saver) { TextFieldValue() } ( I5c3ce , b/155075724 )

• Renamed LayoutModifier2 to LayoutModifier. ( Id29f3 )

• Removed deprecated LayoutModifier interface. ( I2a9d6 )

• Replaced CoreTextField/TextField focusIdentifier parameter with FocusNode in order to integrate with focus subsystem. ( I7ea48 )

• Intrinsic measurements functions in Layout and LayoutModifier2 have an IntrinsicMeasureScope receiver now which provides intrinsics query API with implicitly propagated layout direction. ( Id9945 )

• New Modifier.zIndex() is added to control the drawing order of the children within the same parent layout. elevation property on DrawLayerModifier is renamed to shadowElevation and doesn't control the drawing order anymore. The params order fo DrawShadow is changed: elevation is now the first one and the shape is the second one with a RectangleShape default. ( I20150 , b/152417501 )

• RectangleShape moved from androidx.ui.foundation.shape.* to androidx.ui.graphics.* ( Ia74d5 , b/154507984 )

• TextField API update - merged onFocus and onBlur callbacks into a single onFocusChange(Boolean) callback with parameter ( I66cd3 )

• Added verticalGravity and horizontalGravity parameters to Row and Column, respectively. ( I7dc5a )

• Updated wrapContentWidth and wrapContentHeight to expect vertical or horizontal Alignment rather than any Alignment. The gravity modifier was updated to accept vertical or horizontal Alignment. Row, Column and Stack were updated to support custom continuous Alignments. ( Ib0728 )

• Created PixelMap API to support querying pixel information from an ImageAsset. ( I69ad6 )

• Removes ProvideContentColor, instead just use ContentColorAmbient directly with Providers ( Iee942 )

• ui-text-compose module is renamed as ui-text. ui-text now contains CoreText and CoreTextField composables ( Ib7d47 )

• ui-text module is renamed as ui-text-core ( I57dec )

• Moved ui-framework/CoreText, CoreTextField composables under ui-text-compose. You might want to include ui-text-compose in your project. ( I32042 )

• Improve DrawModifier API:

  • Made the receiver scope for draw() ContentDrawScope
  • Removed all parameters on draw()
  • DrawScope has same interface as former CanvasScope
  • ContentDrawScope has drawContent() method ( Ibaced , b/152919067 )

• runOnIdleCompose and runOnUiThread are now global functions instead of methods on ComposeTestRule. ( Icbe8f )

• [Mutable]State property delegate operators moved to extensions to support Kotlin 1.4 property delegate optimizations. Callers must add imports to continue using by state { ... } or by mutableStateOf(...) . ( I5312c )

• Added positionInParent and boundsInParent for LayoutCoordinates. ( Icacdd , b/152735784 )

• ColoredRect has been deprecated. Use Box(Modifier.preferredSize(width, height).drawBackground(color)) instead. ( I499fa , b/152753731 )

• Renamed LayoutResult to MeasureResult. ( Id8c68 )

• Added LayoutModifier2, a new API for defining layout modifiers; deprecated LayoutModifier ( If32ac )

• Replaced Modifier plus operator with factory extension functions ( I225e4 )

• Draggable has been moved to modifier ( Id9b16 , b/151959544 )

• ParentData composable is deprecated. You should either create a modifier which implements ParentDataModifier interface, or use LayoutTag modifier if you simply need to tag layout children to recognize them inside the measure block. ( I51368 , b/150953183 )

• Deprecated Center composable. It should be replaced either with the LayoutSize.Fill + LayoutAlign.Center modifier, or with one of the Box or Stack composables with suitable modifiers applied ( Idf5e0 )

• Added VectorPainter API to replace existing subcomposition API for vector graphics. Result of subcomposition is a VectorPainter object instead of a DrawModifier. Deprecated previous DrawVector composables in favor of VectorPainter.

  Renamed Image(Painter) API to PaintBox(Painter) Created Vector composable that behaves like the Image composable except with a VectorAsset instead of an ImageAsset ( I9af9a , b/149030271 )

• Renamed LayoutFlexible to LayoutWeight. Renamed tight parameter to fill. ( If4738 )

• Removed RepaintBoundary in favor of DrawLayerModifier ( I00aa4 )

• DrawVector has been changed from a regular composable function to returning a Modifier drawVector() that will draw the vector as a background to a layout. ( I7b8e0 )

• The Opacity composable function has been replaced with the drawOpacity modifier. ( I5fb62 )

• Replace composable function Clip with modifier drawClip(). DrawClipToBounds is a convenient modifier to use when you only need to clip to the layer bounds with a rectangle shape. ( If28eb )

• Replaced DrawShadow composable function with drawShadow() modifier. Shadows are now drawn as part of LayerModifier. ( I0317a )

• Added LayerModifier, a modifier that allows adding a RenderNode for a Layout. It allows setting clipping, opacity, rotation, scaling, and shadows. This will replace RepaintBoundary. ( I7100d , b/150774014 )

• androidx.compose.ViewComposer has been moved to androidx.ui.node.UiComposer androidx.compose.Emittable has been removed. It was redundant with ComponentNode. androidx.compose.ViewAdapters has been removed. They are no longer a supported use case. Compose.composeInto has been deprecated. Use setContent or setViewContent instead. Compose.disposeComposition has been deprecated. Use the dispose method on the Composition returned by setContent instead. androidx.compose.Compose.subcomposeInto has moved to androidx.ui.core.subcomposeInto ComponentNode#emitInsertAt has been renamed to ComponentNode#insertAt ComponentNode#emitRemoveAt has been renamed to ComponentNode#removeAt ComponentNode#emitMode has been renamed to ComponentNode#move ( Idef00 )

• Deprecated Wrap composable. It can be replaced either with the LayoutAlign modifier or with the Stack composable ( Ib237f )

• WithConstraints got LayoutDirection parameter ( I6d6f7 )

• Made the layout direction be propagated from parent layout node to children. Added layout direction modifier. ( I3d955 )

• Stack component supports right-to-left directionality ( Ic9e00 )

• DrawShape composable was removed. Use DrawBackground modifier instead. ( I7ceb2 )

• Support right-to-left direction in LayoutPadding modifier ( I9e8da )

• Added AdapterList, a scrolling list component that only composes and lays out the visible items. Currently known issues include that it is vertical-only and does not fully handle all cases of changes to its children. ( Ib351b )

• Updated the ComposeFlags.COMPOSER_PARAM flag to be true , which will change the code generation strategy for the compose plugin. At a high level, this causes @Composable functions to be generated with an additional synthetic parameter, which is passed through to subsequent @Composable calls in order for the runtime to properly manage execution. This is a significant binary breaking change, however, should preserve source-level compatibility in all sanctioned usage of compose. ( I7971c )

• Added Canvas component. This composable takes up some size (provided by user) and allows you to draw using CanvasScope ( I0d622 )

• Density and DensityScope were merged into one interface. Instead of ambientDensity() you can now use DensityAmbient.current. Instead of withDensity(density) just with(density) ( I11cb1 )

• Changed LayoutCoordinates to make providedAlignmentLines a Set instead of a Map and have LayoutCoordinates implement the get() operator instead for retrieving a value. This makes it easier for modifiers to modify one or more value of the set without creating a new collection for each modifier. ( I0245a )

• Scrollers now exhibit native Android fling motion behavior. ( I922af , b/147493715 )

• Improvements to the API surface of Constraints ( I0fd15 )

Important changes since 1.6.0

• Material components have been migrated to use the new ripple APIs, and no longer query RippleTheme .
• Material components that previously accepted a MutableInteractionSource and defaulted to remember { MutableInteractionSource() } now accept a nullable MutableInteractionSource and default to null instead. If you are not hoisting and using the MutableInteractionSource , you should pass null. This allows for some components to lazily create an instance only when needed, improving performance. It is also recommended that you make similar changes in your own components.
• BottomDrawer , ModalBottomSheet , BackdropScaffold and standard Bottomsheet have been promoted to stable API.

androidx.compose.material:material-*:1.7.0-alpha01 is released. Version 1.7.0-alpha01 contains these commits.

Behavior Changes

• Material components have been migrated to use the new ripple APIs, and no longer query RippleTheme .

Изменения API

• rememberRipple and RippleTheme have been deprecated from material-ripple, with new ripple and RippleConfiguration APIs added to material and other design system libraries.

• Material components that previously accepted a MutableInteractionSource and defaulted to remember { MutableInteractionSource() } now accept a nullable MutableInteractionSource and default to null instead. If you are not hoisting and using the MutableInteractionSource , you should pass null. This allows for some components to lazily create an instance only when needed, improving performance. It is also recommended that you make similar changes in your own components.

See the list of Material icons for the list of icons that can (and should) be auto-mirrored. The previously provided icon properties for those icons are now marked as deprecated, and provides a replacement-block suggestion to help with the migration. In case you don't have any special handling for mirroring icons on RTL, we recommend migrating to the new set of icons. For example, Icons.Filled.ArrowBack should be refactored to Icons.AutoMirrored.Filled.ArrowBack . ( I4b511 )

19 апреля 2023 г.

androidx.compose.material:material-*:1.5.0-alpha03 is released. Version 1.5.0-alpha03 contains these commits.

Изменения API

• Update BottomDrawer internals to use the new SwipeableV2 APIs. Because of this BottomDrawerState will now only have APIS defined at the class level, it won't inherit methods/properties from SwipeableState . We're using composition with an internal SwipeableV2State .

Версия 1.3.0-бета01

24 августа 2022 г.

androidx.compose.material:material-*:1.3.0-beta01 is released. Версия 1.3.0-beta01 содержит эти коммиты.

Behavior breaking change

Maximum supported elevation in dialogs and popups has been reduced to 8dp.

The maximum supported elevation for Compose dialogs and popups has been reduced from 30dp to 8dp. This change affects both material and ui custom dialogs and popups. This change is made to mitigate an accessibility bug on Android versions below S, and to ensure that accessibility services within those windows are able to interact with the content inside the dialog or popup.

You will only be impacted by this change if you are creating a custom dialog or popup implementation with an elevation set to levels higher than 8dp. Consider lowering the elevation of your dialog or popup. If you need to opt-out from this new behavior, consider forking your own dialog or popup with the desired elevation set. This is not recommended, as accessibility might be negatively impacted and it is on the developer to ensure the bottom part of the dialog or popup is interactable and readable by accessibility services.

Изменения API

• LazyVerticalGrid and LazyHorizontalGrid are now stable. ( I307c0 )
• LazyVerticalGrid/LazyHorizontalGrid and all related apis were moved into .grid subpackage. Please update your imports from androidx.compose.foundation.lazy to androidx.compose.foundation.lazy.grid. ( I2d446 , b/219942574 )
• Reverted previous change of relying solely on a View for WindowInsetsControllerCompat , and again require a Window which is required for managing some window flags. Deprecated ViewCompat.getWindowInsetsController in favor of WindowCompat.getInsetsController to ensure that the correct Window is used (such as if the View is in a dialog). ( I660ae , b/219572936 )
• Text: includeFontPadding is now turned off by default. The clipping issues as a result of includeFontPadding=false is handled and no clipping should occur for tall scripts. ( I31c84 , b/171394808 )

Version 1.2.0-alpha04

23 февраля 2022 г.

androidx.compose.material:material-*:1.2.0-alpha04 is released. Version 1.2.0-alpha04 contains these commits.

Изменения API

• Add support for filter chips ( I39a6e , b/192585545 )
• Added TextFieldDecorationBox and OutlinedTextFieldDecorationBox . Using them together with BasicTextField will help you build custom text field based on Material Design text fields but with more options for customisation.
• Provided a way to adjust horizontal and vertical paddings in text fields. ( I8c9f1 , b/203764564 , b/191543915 , b/189971673 , b/183136600 , b/179882597 , b/168003617 )

• Added ComposableTarget , ComposableTargetMarker and ComposableOpenTarget that allows compile time reporting of when a composable function is called targeting an applier it was not designed to use.

  In most cases the annotations can be inferred by the compose compiler plugin so using these annotation directly should be rare . The cases that cannot be inferred include creating and using a custom applier, abstract composable functions (such as interface methods), fields or global variables that are composable lambdas (local variables and parameters are inferred), or when using ComposeNode or a related composable functions .

  For custom appliers the composable functions that calls ComposeNode or ReusableComposeNode need to add a CompoableTarget annotation for the function and any composable lambda parameter types. It is recommended, however, to create an annotation that is annotated with ComposableTargetMarker and then the marked annotation be used instead of ComposableTarget directly. A composable annotation marked with ComposableTargetMarker is equivalent to a ComposbleTarget with the fully qualified name of the attribute class as the applier parameter. For an example of using ComposableTargetMarker see anroidx.compose.ui.UiComposable . ( I38f11 )

Important changes since 1.0.0

• Stable support for the Android 12 Overscroll effect
• Improvements to touch target sizing
• Note that, with respect to Compose 1.0, Material components will expand their layout space to meet Material accessibility guidelines for touch target size . For instance, Button touch target will expand to a minimum size of 48x48dp, even if you set the Button's size to be smaller. This aligns Compose Material to the same behavior of Material Design Components, providing consistent behavior if you mix Views and Compose. This change also ensures that when you create your UI using Compose Material components, minimum requirements for touch target accessibility will be met.
• Stable Support for Navigation Rail
• Graduates a number of previously experimental APIs to stable
• Support for newer versions of Kotlin

Version 1.1.0-alpha06

13 октября 2021 г.

androidx.compose.material:material-*:1.1.0-alpha06 is released. Version 1.1.0-alpha06 contains these commits.

Изменения API

• A child-less overload for Layout was added, with improved efficiency ( Ib0d9a )
• Implementation of ExposedDropdownMenu based on ExposedDropdownMenuBox with TextField and DropdownMenu inside ( If60b2 )
• dismissOnOutsideClick was added to PopupProperties , replacing dismissOnClickOutside which was deprecated. The new property receives the click position and the anchor bounds, providing finer control over whether onDismissRequest should be invoked or not. For example, this can be useful to prevent anchor dismissal for touches on the anchor.
  • updateAndroidWindowManagerFlags was added to PopupProperties , offering low-level control over the flags passed by the popup to the Android WindowManager. The parameter of the lambda will be the flags calculated from the PopupProperties values that result in WindowManager flags: eg focusable. The result of the lambda will be the final flags which will be passed to the Android WindowManager. By default, updateAndroidWindowManagerFlags will leave the flags calculated from parameters unchanged. This API should be used with caution, only in cases where the popup has very specific behavior requirements. ( I6e9f9 )

Version 1.1.0-alpha05

29 сентября 2021 г.

androidx.compose.material:material-*:1.1.0-alpha05 is released. Version 1.1.0-alpha05 contains these commits.

Изменения API

• Adds minimum touch target sizing for Material components that do not have an accessible touch target. As this adds extra spacing around components to make sure they have a large enough touch target, this may change existing UIs that assume the size of these components is their visual size, and doesn't account for touch target size. You can use the experimental LocalMinimumTouchTargetEnforcement composition local to disable this behavior across a hierarchy, but this is intended only to be a temporary escape hatch while updating existing UIs to account for the new minimum size. ( I9b966 , b/149691127 , b/171509422 )
• Added experimental TextFieldColorsWithIcons interface, extending TextFieldColors to provide InteractionSource to the leadingColor and trailingColor. This enables modifying the appearance of TextField according to the focus state. ( I66923 , b/198402662 )

Version 1.1.0-alpha04

• Added touchBoundsInRoot to SemanticsNode that includes the minimum touch target size so that developers can ensure that touch targets meet accessibility minimums. ( I2e14b , b/197751214 )

Исправления ошибок

• Allow clip to extend touch target bounds beyond the clip region for minimum touch target purposes. ( I43e10 , b/171509422 )
• Updated Divider composable to respect Dp.Hairline for the thickness parameter to support drawing single pixel dividers regardless of display density. ( I16ffb , b/196840810 )

• Profile rules for a library are specified in a text file baseline-prof.txt located in the src/main or equivalent directory. The file specifies a rule per line, where a rule in this case is a pattern for matching to methods or classes in the library. The syntax for these rules is a superset of the human-readable ART profile format that is used when using adb shell profman --dump-classes-and-methods ... . These rules take one of two forms to target either methods or classes.

• A method rule will have the following pattern:

  <FLAGS><CLASS_DESCRIPTOR>-><METHOD_SIGNATURE>
  

• And a class rule will have the following pattern:

  <CLASS_DESCRIPTOR>
  

• Here <FLAGS> is one or more of the characters H , S , and P to indicate whether or not this method should be flagged as "Hot", "Startup", or "Post Startup".

• The <CLASS_DESCRIPTOR> is the descriptor for the class that the targeted method belongs to. For example, the class androidx.compose.runtime.SlotTable would have a descriptor of Landroidx/compose/runtime/SlotTable; .

• The <METHOD_SIGNATURE> is the signature of the method, and includes the name, parameter types, and return types of the method. For example, the method fun isPlaced(): Boolean on LayoutNode has the signature isPlaced()Z .

• These patterns can have wildcards ( ** , * , and ? ) in order to have a single rule encompass multiple methods or classes.

What do the rules do?

• A method that has the flag H indicates that this method is a "hot" method, and should be compiled ahead of time.

• A method that has the flag S indicates that it is a method which is called at startup, and should be compiled ahead of time to avoid the cost of compilation and interpreting the method at startup time.

• A method that has the flag P indicates that it is a method which is called after startup.

• A class that is present in this file indicates that it is used during startup and should be pre-allocated in the heap to avoid the cost of class loading.

Как это работает?

• Libraries can define these rules which will be packaged in AAR artifacts. When an APK is then built which includes these artifacts, these rules are merged together and the merged rules are used to build a compact binary ART profile that is specific to the APK. ART can then leverage this profile when the APK is installed on devices in order to ahead-of-time compile a specific subset of the application to improve the performance of the application, especially the first run. Note that this will have no effect on debuggable applications.

Новые возможности

Behavior Breaking API Change

• BEHAVIOUR-BREAKING: Card now consumes clicks, making clicks added via Card(Modifier.clickable) to be a no-op. Please, use new experimental overload of a Card that accepts onClick. ( Ia8744 , b/183775620 )
  • Added a new Card overload that handles clicks as well as other clickable functionality: indication, interactionSource, enabled/disabled. It wasn't possible to use a regular non-clickable Card with the Modifier.clickable because the Card will not clip the ripple indication in those cases.
• BEHAVIOUR-BREAKING: Surface now consumes clicks, making clicks added via Surface(Modifier.clickable) to be a no-op. Please, use new experimental overload of Surface that accepts onClick. ( I73e6c , b/183775620 )
  • Added a new Surface overload that handles clicks as well as other clickable functionality: indication, interactionSource, enabled/disabled. It wasn't possible to use a regular non-clickable Surface with the Modifier.clickable because the Surface will not clip the ripple indication in those cases.

Изменения API

• FabPosition was converted to inline class from enum to support potential expansion in the future ( I030fb )
• Refactored enum usages to inline classes to avoid issues with exhaustive when statements when new enum values are added. ( I2b5eb )
• Adds a tap timeout to clickable / toggleable to prevent showing a ripple during a scroll / drag ( Ia2704 , b/168524931 )
• ContentDescription and Text semantics properties are no longer single values but lists. This enables to merge them as they are instead of concatenations. Also provided better testing APIs to utilize these changes ( Ica6bf , b/184825850 )
• Modifier.focusModifier() is deprecated and replaced by Modifier.focusTarget() ( I6c860 )
• Replaced FocusState enum with a FocusState interface ( Iccc1a , b/187055290 )
• Removed LocalRippleNativeRendering now that the View-backed ripple implementation is stable ( I7fab3 , b/188569367 )

Исправления ошибок

• Modifier.onGloballyPositioned() was changed to report the coordinates of this modifier in the modifier chain, not the layout coordinates after applying all the modifiers. This means that now the ordering of modifiers is affecting what coordinates would be reported. ( Ieb67d , b/177926591 )
• Added a README for the existing Compose Material catalog. ( If9191 )

Version 1.0.0-beta07

androidx.compose.material:material-*:1.0.0-beta06 is released. Version 1.0.0-beta06 contains these commits.

Изменения API

• Ripple has been migrated to use RippleDrawable internally on Android devices. This means that ripple animations will happen on the RenderThread, and so will be smooth even when the UI thread is under load, such as when navigating between screens. This does not change the API surface of ripple, but there may be behavior changes introduced as a result of this change. To aid the migration, LocalRippleNativeRendering has been added - provide a value of false to this CompositionLocal to fall back to the previous ripple implementation inside the CompositionLocalProvider. This API is temporary and will be removed in the future, so if you run into issues that cause you to use this API, please file a bug . ( I902f8 , b/168777351 , b/183019123 )
• Added CollectionInfo and CollectionItemInfo accessibility APIs that allows to mark collection and its items for accessibility services ( Id54ef , b/180479017 )
• Added accessibility API error that allows to mark a node that contains invalid input ( I12997 , b/180584804 , b/182142737 )

Исправления ошибок

• Updated Compose Material catalog insets implementation from: https://github.com/google/accompanist/pull/365. ( I25dc3 )

Внешний вклад

• [by Jossi Wolf] BottomDrawer now wraps the content of the drawer slot. BottomDrawer doesn't throw an IllegalStateException when the parent has infinite height. The bottom drawer will now open to an expanded state if it is smaller than 50% of its parent. Docs around BottomDrawerState and ModalBottomSheetLayoutState have been updated.

  • ( I99b7d , b/177245490 )

• Modifier.scrollable has been reworked. Now it uses Scrollable interface instead of ScrollableController class ( I4f5a5 , b/174485541 , b/175294473 )

• Modifier.draggable now accepts DraggableState instead of a simple lambda. you can create state via rememberDraggableState { delta -> } to get the same behaviour as before ( Ica70f , b/175294473 )

• ZoomableController.smoothScaleBy and ZoomableController.stopAnimation are now suspend functions. ( I7f970 , b/177457083 )

• Changed Indication#createIndication() to Indication#rememberUpdatedIndication(InteractionState) and removes InteractionState parameter from IndicationInstance#drawIndication(). IndicationInstance should only be responsible for drawing visual effects, and not launching animations / writing state in response to InteractionState changes. These animations and state writes should happen within rememberUpdatedIndication() instead. The indication parameter in Modifier.indication was also changed to be a required parameter. ( Ic1764 , b/152525426 )

Исправления ошибок

• Added new LocalSoftwareKeyboardController composition local API to replace previous SoftwareKeyboardController interface on TextField. ( I658b6 , b/168778053 )

• Changed Indication#createInstance to be @Composable, and changed LocalIndication to contain an Indication, not () -> Indication. ( I5eeea , b/157150564 )
• Moved AlertDialog and DropdownMenu to be Android only for now. Added PopupProperties parameter to DropdownMenu for further configuration of the underlying Popup. ( I9c443 )
• loadFontResource is deprecated. Use fontResource instead. imageResource, loadImageResource, vectorResource, and loadVectorResource are deprecated. Use painterResource instead. ( I6b809 )
• Removed toggle and toggleModifier parameter from DropdownMenu, and renamed dropdownModifier , dropdownOffset and dropdownContent to modifier , offset and content respectively. DropdownMenu now behaves consistently to Popup , where the parent layout is used for the position of the menu. In most cases you can move toggle to be a sibling of DropdownMenu and wrap both in a Box . See the updated sample in the documentation for more information on usage of this API. ( I884fb )
• toIntPx() was renamed to roundToPx(). ( I9b7e4 , b/173502290 )

• Renamed Ambients to match the Ambient -> CompositionLocal rename. Ambients used to be named AmbientFoo, now CompositionLocals are named LocalFoo. ( I2d55d )
• Selection was moved to foundation. ( I7892b )
• Similarly to how we previously removed state { 0 } composable and now promote usage like remember { mutableStateOf(0) } we are going to remove savedInstanceState { 0 } composable. You should use rememberSaveable { mutableStateOf(0) } instead and it will save and restore automatically if the type used inside the MutableState can be stored in the Bundle. If previously you were passing a custom saver object now you need to use a new overload of rememberSaveable which has stateSaver parameter. The usage will look like this: val holder = rememberSaveable(stateSaver = HolderSaver) { mutableStateOf(Holder(0)) } ( Ib4c26 , b/177338004 )
• Added ProgressBarRangeInfo.Indeterminate to mark indeterminate progress bars for accessibility ( I6fe05 )

• @ComposableContract has been deprecated in favor of three more specific annotations.

  • @ComposableContract(restartable = false) has become @NonRestartableComposable

• Parameters on RounderCornerShape, CutCornerShape and CornerBasedShape were renamed from left/right to start/end in order to support the shape's auto mirroring in the rtl direction. AbsoluteRounderCornerShape and AbsoluteCutCornerShape were introduced for the cases when auto-mirroring is not desired. ( I61040 , b/152756983 )

• Changed Tab's text and icon parameters, and BottomNavigationItem's label parameter to be nullable, to better convey the behavior of the component when these parameters are / are not provided, since it affects the size and layout of the component. If you are currently passing emptyContent() to represent no text / icon / label, you should use null instead. ( I57ed4 )

• Renamed contentColorFor color parameter to backgroundColor ( I5bb67 )

• Deprecated TabDefaults and replaced it with TabRowDefaults. ( I0f189 )

• Introduced ColorMatrix API used to modify rgb values of source content Refactored ColorFilter API to be an interface and match the implementation of PathEffect. ( Ica1e8 )

• Removed Recomposer.current() . [Abstract]ComposeView now default to lazily created, window-scoped Recomposers driven by the ViewTreeLifecycleOwner for the window. Recomposition and withFrameNanos-based animation ticks are paused while the host Lifecycle is stopped. ( I38e11 )

Исправления ошибок

• Icon will now scale up to fit its size, respecting size modifiers applied to it. For example Icon(.., modifier = Modifier.size(50.dp) will now draw in a 50x50dp space. ( Ib2ba9 , b/178796190 )

Version 1.0.0-alpha11

January 28, 2021

androidx.compose.material:material-*:1.0.0-alpha11 is released. Version 1.0.0-alpha11 contains these commits.

Изменения API

• Promotes some Material APIs to no longer be @Experimental ( I5d20e )
• Content description parameter has been added to the Image and Icon. It is used to provide description to the accessibility services ( I2ac4c )
• Changes Material stateful parameter interfaces to have @Composable functions that return State<T> . Adds Animatable.asState() to make it easier to convert an Animatable to a State. Also changes animateElevation to be a suspend extension on Animatable. ( If613c )
• Snackbar, SnackbarHost, SnackbarHostState are not @ExperimentalMaterialAPI anymore ( Id1fb5 )
• Changes Typography, Shapes, and TabPosition to no longer be data classes. Adds copy function for Typography and Shapes to replace the generated ones. ( I40037 )
• Deleted some previously deprecated Material APIs ( Ifaa25 )

Исправления ошибок

• onCommit, onDispose, and onActive have been deprecated in favor of SideEffect and DisposableEffect APIs ( If760e )
• TransitionDefinition-based Transition has been deprecated ( I0ac57 )
• Initial State in updateTransition is now supported ( Ifd51d )
• WithConstraints was reworked as BoxWithConstraints and moved to foundation.layout. ( I9420b , b/173387208 )

• Deprecate non-suspend scrollBy, remove non-suspend scrollTo

  We now recommend using suspend functions to control scrolling and wait for the scroll to finish. We are deprecating and/or removing the non-suspend versions of these functions as part of this transition. ( Ie9ced )

• Deprecate non-suspend smoothScrollBy We now recommend using suspend functions to control scrolling and wait for the scroll to finish. We are deprecating the non-suspend versions of these functions as part of this transition. ( I12880 )

• Introduced ComposeContentTestRule , which extends ComposeTestRule and defines setContent , which has been removed from ComposeTestRule . Added a factory method createEmptyComposeRule() that returns a ComposeTestRule and does not launch an Activity for you. Use this when you want to launch your Activity during your test, eg using ActivityScenario.launch ( I9d782 , b/174472899 )

• The ripple used in Button and FloatingActionButton can no longer be customized by providing a new Indication through AmbientIndication - this was never intended to be a way to customize these components and this now makes these components consistent with other Material components. To customize ripples across an application, see RippleTheme. ( I546c5 )

• animateAsState is now animateFooAsState, where Foo is the type of the variable being animated. eg Float, Dp, Offset, etc ( Ie7e25 )

• BasicTextField received a new parameter called decorationBox . It allows to add the decorations like icons, placeholder, label and similar to the text field and increase the hit target area of it. ( I16996 )

• Fix for a bug which made it not possible to set the width of the material text field be less than 280.dp ( I78373 )

• canDrag parameter has been removed from the Modifier.draggable ( Ic4bec , b/175294473 )

• Remove displaySize as it should be avoided. Typically it is better to use size of onRoot() or window size at least. ( I62db4 )

• Surface can now have multiple layout children. ( I66a92 , b/144488459 )

• invalidate and compositionReference() are now deprecated in favor of currentRecomposeScope and rememberCompositionReference respectively. ( I583a8 )

• Changes PopupPositionProvider to use window-relative coordinates, not global coordinates. Renames parentGlobalBounds to anchorBounds, and changes windowGlobalBounds to be windowSize: IntSize ( I2994a )

• Duration and Uptime will be replace with Long milliseconds, and this step removes the dependency of pointer input on those classes. ( Ia33b2 , b/175142755 , b/177420019 )

• AnimatedFloat.fling that accepts FlingConfig has been removed. Please use suspend Animatable.animateDecay instead. ( I4659b , b/177457083 )

• clickable, toggleable and selectable can be created outside of composition now ( I0a130 , b/172938345 , b/175294473 )

• Easing has been changed to a functional interface ( Ib14e5 )

• ScrollableColumn/Row were deprecated. Using ScrollableColumn is less efficient comparing to LazyColumn when you have a large scrolling content because with LazyColumn we can only compose/measure/draw visible elements. To prevent users from going inefficient way we decided to deprecate ScrollableColumn and ScrollableRow and promote usages of LazyColumn and LazyRow instead. Users can still decide they don't need the lazy behaviour and use the modifiers directly like this: Column(Modifier.verticalScroll(rememberScrollState())) ( Ib976b , b/170468083 )

• New items(count: Int) factory method for scope of LazyColumn/LazyRow/LazyVerticalGrid. items(items: List) and itemsIndexed(items: List) are now extension functions so you have to manually import them when used. New extension overloads for Arrays: items(items: Array) and itemsIndexed(Array) ( I803fc , b/175562574 )

• Removed experimental monotonicFrameAnimationClockOf methods ( Ib753f , b/170708374 )

Version 1.0.0-alpha09

16 декабря 2020 г.

androidx.compose.material:material-*:1.0.0-alpha09 is released. Version 1.0.0-alpha09 contains these commits.

Изменения API

• added API to manually trigger settle animation and drag in Modifier.swipeable ( Iaa17a , b/162408885 )
• Renamed *Constants objects such as ButtonConstants to end with Defaults instead, such as ButtonDefaults. Also removes unnecessary default prefixes from properties in these new objects. ( Ibb915 , b/159982740 )

• Compose supports property getters that can make composable invocations. Support for this is not going away, but the syntax for declaring a property getter as being @Composable is changing.

  The now-deprecated syntax for doing this was by annotating the property itself:

      @Composable val someProperty: Int get() = ...
  

  The now-correct syntax for doing this is by annotating the getter of the property:

     val someProperty: Int @Composable get() = ...
  

  Both syntaxes will work for some time, but the former deprecated syntax will eventually become a compile error. ( Id9197 )

• Added androidx.compose.material:material-ripple library containing ripple APIs to allow building interactive components without needing the rest of the Material library. rememberRippleIndication has been deprecated and replaced with rememberRipple. ( Ibdf11 )

Исправления ошибок

• Updated TextFieldValue API
  • made TextFieldValue.composition readonly
  • removed exception thrown for invalid selection range ( I4a675 , b/172239032 )
• Added a new Modifier.drawLayer() overload. It takes a lambda block on a new GraphicsLayerScope where you define the layer parameters in a way which allows to skip recomposition and relayout when the state change happens. DrawLayerModifier is now internal in preparation to migrating its logic into placeable.placeWithLayer() method of LayoutModifier ( I15e9f , b/173030831 )

Изменения API

• Emphasis has been deprecated and replaced with AmbientContentAlpha. AmbientContentAlpha is a simpler abstraction that represents the preferred content alpha for part of the hierarchy, similar to how AmbientContentColor represents the preferred content color. Text and Icon now consume the current value from AmbientContentAlpha by default, and you can manually do: color.copy(alpha = AmbientContentAlpha.current) to have the same effect in your components. Instead of using ProvideEmphasis, you can just directly provide a value through AmbientContentAlpha, and use the new default levels in ContentAlpha to replace the old EmphasisLevels. ( Idf03e , b/159017896 )
• Adds androidx.compose.material.AmbientContentColor to replace androidx.compose.foundation.AmbientContentColor ( I84f7b , b/172067770 )

• Added maxLines to TextFields ( Ib2a5b )
• Update TextFields to accept KeyboardOptions ( Ida7f3 )
• Surface now uses the absolute (total) elevation when calculating elevation overlays, so a Surface nested in another Surface will use the combined elevation to draw the overlay. ( I7bd2b , b/171031040 )

Исправления ошибок

• captureToBitmap moved to captureToImage . ( I86385 )
• The foundation AmbientTextStyle, ProvideTextStyle, and AmbientContentColor have been deprecated. Instead use the new versions available in the Material library. For non-Material applications, you should instead create your own design system specific theming ambients that can be consumed in your own components. ( I74acc , b/172067770 )
• foundation.Text has been deprecated and replaced with material.Text. For a basic, unopinionated text API that does not consume values from a theme, see androidx.compose.foundation.BasicText. ( If64cb )
• Rename KeyboardOptions as ImeOptions ( I82f36 )
• Moved KeyboardType and ImeAction into KeyboardOptions ( I910ce )
• BaseTextField has been deprecated. Use BasicTextField instead. ( I896eb )

• FirstBaseline and LastBaseline were moved to androidx.compose.ui.layout package ( Ied2e7 )
• Updated Icon API to take in Color.Unspecified as a possible tint color which will draw the provided asset or painter without a ColorFilter. Previously attempts to ignore tinting with Color.Unspecified would tint with a transparent color ending up with nothing rendered at all. ( I049e2 , b/171624632 )
• relativePaddingFrom was renamed to paddingFrom. The paddingFromBaseline modifier was added, as convenience for specifying distances from layout bounds to text baselines. ( I0440a , b/170633813 )
• LaunchedTask was renamed to LaunchedEffect for consistency with the SideEffect and DisposableEffect APIs. LaunchedEffect with no subject params is not permitted in order to encourage best practices. ( Ifd3d4 )
• MeasureResult was moved out of MeasureScope. ( Ibf96d , b/171184002 )
• Several layout related symbols were moved from androidx.compose.ui to androidx.compose.layout.ui. ( I0fa98 , b/170475424 )

Изменения API

• androidx.compose.foundation.Icon has been moved to androidx.compose.material.Icon. You can also use the Image component / Modifier.paint() with a Painter if you do not want to use the Material library. ( I9f622 )
• Adds FloatingActionButtonElevation to represent elevation used by FABs in different states. See FloatingActionButtonConstants.defaultElevation() for the default implementation ( I2d4f5 )
• Adds SwitchColors interface to represent colors used by a Switch in different states. See SwitchConstants.defaultColors to customize these colors. ( I93805 )

• Adds CheckboxColors interface to represent colors used by a checkbox in different states. See CheckboxConstants.defaultColors() to customize the colors used in different states. ( I7dbdb )

Исправления ошибок

• Material components do not set the elevation as zIndex anymore. Which means that within the same parent the child with larger shadow size will not be drawn on top of the child with the smaller one automatically. If you still need such behavior please set Modifier.zIndex() manually where needed ( I70417 , b/170623932 )
• Deprecate VectorPainter in favor of rememberVectorPainter to better indicate that the composable API internally leverages 'remember' to persist data across compositions. ( Ifda43 )

• Deprecates contentColor() and currentTextStyle() APIs, and replaces them with AmbientContentColor and AmbientTextStyle ambients respectively. You can access the current value by using .current on the ambient property, as with any other ambient. This was change was made for consistency and to avoid having multiple ways to accomplish the same thing. Additionally renames some ambient properties to better describe their purpose as follows:

  • ContentColorAmbient -> AmbientContentColor
  • TextStyleAmbient -> AmbientTextStyle
  • IndicationAmbient -> AmbientIndication
  • EmphasisAmbient -> AmbientEmphasisLevels
  • RippleThemeAmbient -> AmbientRippleTheme ( I37b6d )

• Adds AmbientElevationOverlay, allowing customizing / disabling the default elevation overlay applied to Surfaces in dark theme. ( I5b74d )

Исправления ошибок

• As part of the standardization of sentinel values for inline classes, rename Color.Unset to Color.Unspecified for consistency with other inline classes ( I97611 , b/169797763 )
• TextOverflow.None is introduced. When overflow is None, Text won't handle overflow anymore, and it will report its actual size to LayoutNode. ( I175c9 , b/158830170 )
• launchInComposition renamed to LaunchedTask to match Compose API guidelines ( I99a8e )
• OnPositionedModifier is renamed to OnGloballyPositionedModifier and onPositioned() is renamed to onGloballyPositioned(). ( I587e8 , b/169083903 )

  • ( I8f5c7 , b/168762961 )
• foundation.Box was deprecated. Please use foundation.layout.Box instead. ( Ie5950 , b/167680279 )
• Stack was renamed to Box. The previously existing Box will be deprecated in favor of the new Box in compose.foundation.layout. The behavior of the new Box is to stack children one on top of another when it has multiple children - this is different from the previous Box, which was behaving similar to a Column. ( I94893 , b/167680279 )

• Added params in Modifier.swipeable for changing the amount of resistance when swiping past the bounds. Removed [min/max]Value params. ( I93d98 )
• Added backgroundColor parameter to LinearProgressIndicator and removed internal padding from CircularProgressIndicator. Added new ProgressIndicatorConstants.DefaultProgressAnimationSpec which can be used as the default AnimationSpec when animating progress between values ( If38b5 , b/161809914 , b/161804677 )
• Optional param velocityThreshold added to Modifier.swipeable. ( I698ba )
• bottomBarSize, fabSize and others and not available anymore in ScaffoldState. Use Modifier.onPosition instead on the component you'd like to know the size of. contentColor and Modifier pamateres have been added to Scaffold ( Ic6f7b , b/161811485 , b/157174382 )
• Renames and reorders some parameters in Tab for consistency with other APIs ( Ia2d12 , b/161807532 )
• Splits TabRow into TabRow and ScrollableTabRow, removing isScrollable from TabRow. Also exposes edgePadding in ScrollableTabRow, which allows controlling the free space before / after the tabs. ( I583e8 , b/161809544 )
• The TabRow object has been removed, replacing it with TabConstants. TabRow.TabPosition has moved to be top level (TabPosition), and indicatorContainer has been renamed to indicator . See the samples and documentation for detailed information on how to use the updated API, and defaults. ( I54d45 , b/161809544 )
• The thresholds param in Modifier.swipeable was tweaked; it now takes a pair of states (of type T) and returns the threshold between them in the form of a ThresholdConfig. A param dismissThresholds was added to SwipeToDismiss, which is a lambda (DismissDirection) -> ThresholdConfig. ( Ie1080 )
• Slider has more colors for granular customization ( I73e64 , b/161810475 )

• Add an experimental material component SwipeToDismiss. ( I129e5 )

Исправления ошибок

• Removed onChildPositioned and OnChildPositionedModifier . Developers should use onPositioned and OnPositionedModifier on the child layout instead. ( I4522e , b/162109766 )
• Added mergePolicy lambda to SemanticsPropertyKey. This can be used to define a custom policy for mergeAllDescendants semantics merging. The default policy is to use the parent value if already present, otherwise the child value. ( Iaf6c4 , b/161979921 )
• IntSize is now an inline class ( I2bf42 )
• PlacementScope.placeAbsolute() was renamed to PlacementScope.place() , and the previous PlacementScope.place() was renamed to PlacementScope.placeRelative() . As a result, the PlacementScope.place() method will not automatically mirror the position in right-to-left contexts anymore. If this is desired, use PlacementScope.placeRelative() instead. ( I873ac , b/162916675 )

( Ibae84 )
• Renamed ColorPalette to Colors, to better map to the Material color system and remove confusion over ColorPalette being a 'generic' theming object, as opposed to being a specific implementation of the Material color system. Additionally renames lightColorPalette and darkColorPalette to lightColors and darkColors respectively. ( I9e976 , b/161812111 )
• Renames BottomNavigationItem's text parameter to label , onSelected to onSelect , activeColor to selectedContentColor , inactiveColor to unselectedContentColor and updates parameter ordering to match guidelines. ( Icb605 , b/161809324 )

Version 0.1.0-dev15

22 июля 2020 г.

androidx.compose.material:material:0.1.0-dev15 , androidx.compose.material:material-icons-core:0.1.0-dev15 , and androidx.compose.material:material-icons-extended:0.1.0-dev15 are released. Version 0.1.0-dev15 contains these commits.

Dependencies Update

• To use the 0.1.0-dev15 version of Compose, you will need to update your dependencies according to the new code snippets shown above in Declaring dependencies .

Изменения API

• @Model annotation is now deprecated. Use state and mutableStateOf as alternatives. This deprecation decision was reached after much careful discussion.

  Обоснование

  Rationale includes but is not limited to:

  • Reduces API surface area and concepts we need to teach
  • More closely aligns with other comparable toolkits (Swift UI, React, Flutter)
  • Reversible decision. We can always bring @Model back later.
  • Removes corner-case usage and difficult to answer questions about configuring @Model as things we need to handle
  • @Model data classes, equals, hashcode, etc.
  • How do I have some properties “observed” and others not?
  • How do I specify structural vs. referential equality to be used in observation?
  • Reduces “magic” in the system. Would reduce the likelihood of someone assuming system was smarter than it is (ie, it knowing how to diff a list)
  • Makes the granularity of observation more intuitive.
  • Improves refactorability from variable -> property on class
  • Potentially opens up possibilities to do hand-crafted State-specific optimizations
  • More closely aligns with the rest of the ecosystem and reduces ambiguity towards immutable or us “embracing mutable state”

  Migration Notes

  Almost all existing usages of @Model are fairly trivially transformed in one of two ways. The example below has a @Model class with two properties just for the sake of example, and has it being used in a composable.

  @Model class Position(
   var x: Int,
   var y: Int
  )
  
  @Composable fun Example() {
   var p = remember { Position(0, 0) }
   PositionChanger(
     position=p,
     onXChange={ p.x = it }
     onYChange={ p.y = it }
   )
  }
  

  Alternative 1: Use State<OriginalClass> and create copies.

  This approach is made easier with Kotlin's data classes. Essentially, make all previously var properties into val properties of a data class, and then use state instead of remember , and assign the state value to cloned copies of the original using the data class copy(...) convenience method.

  It's important to note that this approach only works when the only mutations to that class were done in the same scope that the State instance is created. If the class is internally mutating itself outside of the scope of usage, and you are relying on the observation of that, then the next approach is the one you will want to use.

  data class Position(
   val x: Int,
   val y: Int
  )
  
  @Composable fun Example() {
   var p by state { Position(0, 0) }
   PositionChanger(
     position=p,
     onXChange={ p = p.copy(x=it) }
     onYChange={ p = p.copy(y=it) }
   )
  }
  

  Alternative 2: Use mutableStateOf and property delegates

  This approach is made easier with Kotlin's property delegates and the mutableStateOf API which allows you to create MutableState instances outside of composition. Essentially, replace all var properties of the original class with var properties with mutableStateOf as their property delegate. This has the advantage that the usage of the class will not change at all, only the internal implementation of it. The behavior is not completely identical to the original example though, as each property is now observed/subscribed to individually, so the recompositions you see after this refactor could be more narrow (a good thing).

  class Position(x: Int, y: Int) {
   var x by mutableStateOf(x)
   var y by mutableStateOf(y)
  }
  
  // source of Example is identical to original
  @Composable fun Example() {
   var p = remember { Position(0, 0) }
   PositionChanger(
     position=p,
     onXChange={ p.x = it }
     onYChange={ p.y = it }
   )
  }

• onFocusChange callback in text fields renamed to onFocusChanged ( Ida4a1 )

• Added thresholds param in stateDraggable to specify thresholds between anchors. This was used to set a 56dp threshold in bottom drawer. Also BottomDrawerLayout now uses a separate BottomDrawerState enum. ( I533fa )

• Removes previously deprecated Modifier.ripple. Clickable now uses ripple as the default indication (if you have a MaterialTheme {} set in your application) so in most cases you can just use clickable and get ripple indication for free. If you need to customize the color / size / bounded parameter for the ripple, you can manually create a RippleIndication and pass it to clickable as the indication parameter. ( I663b2 , b/155375067 )

• Removed deprecated override of FilledTextField composable ( I7f8f8 )

• Rename Button object (containing the defaults used by Button function) to ButtonConstants ( I7c5f7 , b/159687878 )

• Button's content slot now behaves as Row (useful when you need to have an icon with a text, see samples on Button how to write it) ( I0ff10 , b/158677863 )

• Added Material Outlined Textfield ( I1a518 )

• androidx.ui.foundation.TextFieldValue and androidx.ui.input.EditorValue is deprecated. TextField, FilledTextField and CoreTextField composables that uses that type is also deprecated. Please use androidx.ui.input.TextFieldValue instead ( I4066d , b/155211005 )

• TabRow.TabPosition not contains position in Dp, not in IntPx ( I34a07 , b/158577776 )

• Replaced usage of IntPx with Int. Replaced IntPxPosition with IntOffset. Replaced IntPxSize with IntSize. ( Ib7b44 )

• In order to consolidate the number of classes used to represent sizing information, standardize on usage of the Size class instead of PxSize. This provides the benefits of an inline class to leverage a long to pack 2 float values to represent width and height represented as floats. ( Ic0191 )

• Deprecates Modifier.ripple. Clickable now uses ripple as the default indication (if you have a MaterialTheme {} set in your application) so in most cases you can just use clickable and get ripple indication for free. If you need to customize the color / size / bounded parameter for the ripple, you can manually create a RippleIndication and pass it to clickable as the indication parameter. ( I101cd , b/155375067 )

• Scaffold API has been reworked: few parameters changed their name, added new parameters for better customization. Added getter to query sizes of Fab, TopBar and BottomBar ( I0e7ce )

• Allow to show/hide software keyboard manually using SoftwareKeyboardController ( Ifb9d6 , b/155427736 )

• Modifier.indication has been added to foundation package. Use it to show press/drag/other indication on your custom interactable elements ( I8425f , b/155287131 )

• Consolidated CanvasScope implementations so there is now just DrawScope and ContentDrawScope Renamed CanvasScope to DrawScope. Updated DrawScope to implement Density interface and provide LayoutDirection Deleted DrawScope subclass in ContentDrawScope Painter and PainterModifier have been updated to no longer maintain an RTL property themselves as DrawScope provides this already without manually providing it ( I1798e )

• Renames Emphasis.emphasize() to Emphasis.applyEmphasis() ( Iceebe )

• Disabled buttons now visually follows the Material Design specification ( I47dcb , b/155076924 )

• FilledTextField gets ime action, visual transformation and keyboard type support ( I1f9cf , b/155075201 )

• Adds strokeWidth parameter to CircularProgressIndicator to customize the stroke size. To change the stroke size (height) of a LinearProgressIndicator, you can use Modifier.preferredHeight() or another size modifier. ( Icea16 , b/154919081 )

• Adds strokeWidth parameter to CircularProgressIndicator to customize the stroke size. To change the stroke size (height) of a LinearProgressIndicator, you can use Modifier.preferredHeight() or another size modifier. ( Icea16 , b/154919081 )

• Added slot API for trailing and leading icons in the FilledTextField and handling of the error state ( Ic12e0 )

• FAB's and Extended FAB's default color has been changed to MaterialTheme.colors.secondary. ( I3b9b9 , b/154118816 )

• Replaced all nullable Color uses in API with non-nullable and use Color.Unset instead of null ( Iabaa7 )

• Renamed EdgeInsets to InnerPadding. Renamed innerPadding parameter of Material Buttons to paddding. ( I66165 )

• Slider is now stateless. Users will need to pass and update state by themselves, just like in any other control. ( Ia00aa )

• StaticDrawer was removed. If you need it, use Box with material-spec'ed width instead ( I244a7 )

• Added Material Design implementation of Filled Text Field ( Ic75cd )

• Added modifier param to ListItem and reordered params to promote trailing lambda body ( I66e21 )

• Adds defaultFontFamily constructor parameter to Typography, allowing specifying the default font family that will be used for any provided TextStyles that do not have a family set. ( I89d07 )

• Temporarily removed Material Data Tables from the API surface. ( Iaea61 )

• Renamed paramaters in Divider composable ( Ic4373 )

• children ( Ia6d19 )

• Removes MaterialTheme.emphasisLevels, instead use EmphasisAmbient.current to retrieve the emphasis levels ( Ib5e40 )

• Shape theming system is updated according to the Material design specification. Now you can provide small, medium and large shapes to be used by most of the components ( Ifb4d1 )

• Changed MaterialTheme APIs such as MaterialTheme.colors(), MaterialTheme.typography() to be properties instead of functions. Remove parentheses from existing calls, no behavioral change is expected. ( I3565a )

• Refactored FloatingActionButton APIs to accept composable lambdas instead of primitives. See updated samples for usage information. ( I00622 )

• add enabled param to Checkbox, Switch and Toggleable ( I41c16 )

• Ripple is now a Modifier. While Clickable is not yet converted the recommended usage is Clickable(onClick = { ... }, modifier = ripple()) ( Ie5200 , b/151331852 , b/150060763 )

• Surface and Card were moved from androidx.ui.material.surface to androidx.ui.material ( I88a6d , b/150863888 )

• Button, FloatingActionButton and Clickable now have a separate enabled param. Some of the params on Button were renamed or reordered. ( I54b5a )

• Renamed Image to ImageAsset to better differentiate the difference between the Image data and the upcoming Image composable used to participate in layout and draw content. _Body:Created extension method on android.graphics.Bitmap, Bitmap.asImageAsset(), to create an instance of an ImageAsset useful for combining traditional Android application development with the compose framework ( Id5bbd )

• Removed Snackbar API with String parameters in favour of using the overload that accepts composable lambdas. See updated samples for usage information ( I55f80 )

• Refactored Tab APIs to accept text and icon lambdas, ( Ia057e )

• Added BottomNavigation component, see the docs and samples for usage information ( I731a0 )

• Added Icon, IconButton and IconToggleButton, removing AppBarIcon. You can directly replace existing usages of AppBarIcon with IconButton, and they will now have the correct touch target. See the samples for usage information, and see Icons for the provided Material Icons you can use directly with these components. ( I96849 )

• Replaced ButtonStyle with distinct functions and removed text (string) overload. See updated samples for usage information. ( If63ab , b/146478620 , b/146482131 )

• rename Border modifier to DrawBorder ( I8ffcc )

• LayoutCoordinates no longer has a position property. The position property does not make sense when considering LayoutModifiers, rotation, or scaling. Instead, developers should use parentCoordinates and childToLocal() to calculate the transform from one LayoutCoordinate to another.

  LayoutCoordinates uses IntPxSize for the size property instead of PxSize. Layouts use integer pixel sizes for layouts, so all layout sizes should use integers and not floating point values. ( I9367b )

• Breaking changes to the ambients API. See log and Ambient<T> documentation for details ( I4c7ee , b/143769776 )

• Scaffold material component has been added. Scaffold implements ( I7731b )

Исправления ошибок

• FocusModifier is deprecated in favor of Modifier.focus, Modifier.focusRequester, Modifier.focusObserver. FocusState and FocusDetailedState are deprecated in favor of FocusState2 ( I46919 , b/160822875 , b/160922136 )
• VerticalScroller and HoriziontalScroller have been deprecated. Use ScrollableColumn and ScrollableRow for build-in experience with Column/Row behaviour and parameters, or Modifier.verticalScroll and Modifier.horizontalScroll on your own element. Similarly, ScrollerPosition has been deprecated in favor of ScrollState' ( I400ce , b/157225838 , b/149460415 , b/154105299 )

• Single-value semantics properties now use a calling style. For example, 'semantics { hidden = true }' is now written as: 'semantics { hidden() }'. ( Ic1afd , b/145951226 , b/145955412 )
• Several testing APIs were renamed to be more intuitive. All findXYZ APIs were renamed to onNodeXYZ. All doXYZ APIs were renamed to performXYZ. ( I7f164 )
• Transition API has been changed to return a TransitionState instead of passing the TransitionState to children. This makes the API more consistent with animate() APIs. ( I24e38 )
• An IntBounds unit class has been added, representing integer pixel bounds from layout. The API of PopupPositionProvider has been updated to use it. ( I0d8d0 , b/159596546 )
• A new optional flag useUnmergedTree was added to test finders. ( I2ce48 )
• Removed obsolete size testing APIs. ( Iba0a0 )
• Removed Shader inline class that wrapped the NativeShader expect class Renamed NativeShader to Shader. The wrapped Shader inline class did not add anything valuable to the API surface and was an inline class, so use the NativeShader class directly. ( I25e4d )
• Popups, Dialogs and Menus are now inheriting the contextual MaterialTheme ( Ia3665 , b/156527485 )
• Material DropdownMenu are now scrollable. ( Ide699 )
• Removed layout direction parameter from the measure block of the Layout() function. Layout direction is however available inside the callback through the measure scope object ( Ic7d9d )
• Use AnimationSpec instead of AnimationBuilder in the top level APIs to clarify the concept of static animation specification -Improve the transition DSL by removing the lambda requirement for creating AnimationSpecs such as tween, spring. They instead take constructor params directly. -Improve the overall ease of use of AnimationSpec opening up constructors instead of relying on builders -Change the duration and delay for KeyFrames and Tween to Int. This eliminates unnecessary type casts and method overloading (for supporting both Long and Int). ( Ica0b4 )
• Switch now appears in a disabled state when enabled is set to false ( If4624 , b/155941869 , b/159331694 )
• Modifier.tag was renamed to Modifier.layoutId, to avoid confusion with Modifier.testTag. ( I995f0 )
• Alignment line Int positions returned from Placeable#get(AlignmentLine) are now non-null. If the queried alignment line is missing, AlignmentLine.Unspecified will be returned. ( I896c5 , b/158134875 )

• Refactored Radius class to be an inline class. Removed companion creation methods in favor of function constructor with default parameter to have the radius along the y-axis match that of the mandatory x-axis radius parameter.

  Updated DrawScope.drawRoundRect to consume a single Radius parameter instead of 2 separate float values for the radius along the x and y axis ( I46d1b )

• In order to consolidate the number of classes used to represent positioning information, standardize on usage of the Offset class instead of PxPosition. This provides the benefits of an inline class to leverage a long to pack 2 float values to represent x and y offsets represented as floats. ( I3ad98 )

• Replaced usage of Px class in various compose classes as part of the large refactoring effort to only rely on Dp and primitive types for pixel parameters. Deleted Px class in its entirety ( I3ff33 )

• Toggleable component has been deprecated. Use Modifier.toggleable instead ( I35220 , b/157642842 )

• Replaced usage of Px class in various compose classes as part of the large refactoring effort to only rely on Dp and primitive types for pixel parameters ( I086f4 )

• Modifier.semantics has been undeprecated to allow usages for high level components. ( I4cfdc )

• DrawLayer modifiers api has been changed: outlineShape renamed to shape and has the RectangleShape default value and now non-nullable; clipToOutline renamed to clip; clipToBounds removed as it is the same as clip == true with RectangleShape ( I7ef11 , b/155075735 )

• Updated higher level compose APIs that expose a Canvas to expose CanvasScope instead. This removes the need for consumers to maintain their own Paint objects. For consumers that still require access to a Canvas they can use the drawCanvas extension method which provides a callback to issue drawing commands with the underlying Canvas. ( I80afd )

• AlignmentLineOffset composable is deprecated, please use relativePaddingFrom() modifier instead. CenterAlignmentLine composable is removed. ( I60107 )

• WithConstraints trailing lambda API has been changed. Now instead of two params it has a receiver scope which in addition to constraints and layoutDirection provides minWidth, maxWidth, minHeight and maxHeight properties in Dp ( I91b9a , b/149979702 )

• Added defaultMinSizeConstraints layout modifier, which sets size constraints to the wrapped layout only when the incoming corresponding constraints are unspecified (0 for min constraints and infinity for max constraints). ( I311ea , b/150460257 )

• FocusManagerAmbient is removed. Use FocusModifier.requestFocus to obtain focus. ( Ic4826 )

• Created CanvasScope API that wraps a Canvas object to expose a stateless, declarative drawing API surface. Transformations are contained within their own receiver scope and sizing information is also scoped to corresponding inset bounds. It does not require a consumer to maintain its own Paint state object for configuring drawing operations.

  Added CanvasScopeSample as well as updated the demo app to include a declarative graphics demo ( Ifd86d )

• Add cursor color customisation to the TextField ( I6e33f )

• TextFieldValue used with TextField can now be survive activity recreation when used like this: var text by savedInstanceState(saver = TextFieldValue.Saver) { TextFieldValue() } ( I5c3ce , b/155075724 )

• Renamed LayoutModifier2 to LayoutModifier. ( Id29f3 )

• Removed deprecated LayoutModifier interface. ( I2a9d6 )

• Replaced CoreTextField/TextField focusIdentifier parameter with FocusNode in order to integrate with focus subsystem. ( I7ea48 )

• Intrinsic measurements functions in Layout and LayoutModifier2 have an IntrinsicMeasureScope receiver now which provides intrinsics query API with implicitly propagated layout direction. ( Id9945 )

• New Modifier.zIndex() is added to control the drawing order of the children within the same parent layout. elevation property on DrawLayerModifier is renamed to shadowElevation and doesn't control the drawing order anymore. The params order fo DrawShadow is changed: elevation is now the first one and the shape is the second one with a RectangleShape default. ( I20150 , b/152417501 )

• RectangleShape moved from androidx.ui.foundation.shape.* to androidx.ui.graphics.* ( Ia74d5 , b/154507984 )

• TextField API update - merged onFocus and onBlur callbacks into a single onFocusChange(Boolean) callback with parameter ( I66cd3 )

• Added verticalGravity and horizontalGravity parameters to Row and Column, respectively. ( I7dc5a )

• Updated wrapContentWidth and wrapContentHeight to expect vertical or horizontal Alignment rather than any Alignment. The gravity modifier was updated to accept vertical or horizontal Alignment. Row, Column and Stack were updated to support custom continuous Alignments. ( Ib0728 )

• Created PixelMap API to support querying pixel information from an ImageAsset. ( I69ad6 )

• Removes ProvideContentColor, instead just use ContentColorAmbient directly with Providers ( Iee942 )

• ui-text-compose module is renamed as ui-text. ui-text now contains CoreText and CoreTextField composables ( Ib7d47 )

• ui-text module is renamed as ui-text-core ( I57dec )

• Moved ui-framework/CoreText, CoreTextField composables under ui-text-compose. You might want to include ui-text-compose in your project. ( I32042 )

• Improve DrawModifier API:

  • Made the receiver scope for draw() ContentDrawScope
  • Removed all parameters on draw()
  • DrawScope has same interface as former CanvasScope
  • ContentDrawScope has drawContent() method ( Ibaced , b/152919067 )

• runOnIdleCompose and runOnUiThread are now global functions instead of methods on ComposeTestRule. ( Icbe8f )

• [Mutable]State property delegate operators moved to extensions to support Kotlin 1.4 property delegate optimizations. Callers must add imports to continue using by state { ... } or by mutableStateOf(...) . ( I5312c )

• Added positionInParent and boundsInParent for LayoutCoordinates. ( Icacdd , b/152735784 )

• ColoredRect has been deprecated. Use Box(Modifier.preferredSize(width, height).drawBackground(color)) instead. ( I499fa , b/152753731 )

• Renamed LayoutResult to MeasureResult. ( Id8c68 )

• Added LayoutModifier2, a new API for defining layout modifiers; deprecated LayoutModifier ( If32ac )

• Replaced Modifier plus operator with factory extension functions ( I225e4 )

• Draggable has been moved to modifier ( Id9b16 , b/151959544 )

• ParentData composable is deprecated. You should either create a modifier which implements ParentDataModifier interface, or use LayoutTag modifier if you simply need to tag layout children to recognize them inside the measure block. ( I51368 , b/150953183 )

• Deprecated Center composable. It should be replaced either with the LayoutSize.Fill + LayoutAlign.Center modifier, or with one of the Box or Stack composables with suitable modifiers applied ( Idf5e0 )

• Added VectorPainter API to replace existing subcomposition API for vector graphics. Result of subcomposition is a VectorPainter object instead of a DrawModifier. Deprecated previous DrawVector composables in favor of VectorPainter.

  Renamed Image(Painter) API to PaintBox(Painter) Created Vector composable that behaves like the Image composable except with a VectorAsset instead of an ImageAsset ( I9af9a , b/149030271 )

• Renamed LayoutFlexible to LayoutWeight. Renamed tight parameter to fill. ( If4738 )

• Removed RepaintBoundary in favor of DrawLayerModifier ( I00aa4 )

• DrawVector has been changed from a regular composable function to returning a Modifier drawVector() that will draw the vector as a background to a layout. ( I7b8e0 )

• The Opacity composable function has been replaced with the drawOpacity modifier. ( I5fb62 )

• Replace composable function Clip with modifier drawClip(). DrawClipToBounds is a convenient modifier to use when you only need to clip to the layer bounds with a rectangle shape. ( If28eb )

• Replaced DrawShadow composable function with drawShadow() modifier. Shadows are now drawn as part of LayerModifier. ( I0317a )

• Added LayerModifier, a modifier that allows adding a RenderNode for a Layout. It allows setting clipping, opacity, rotation, scaling, and shadows. This will replace RepaintBoundary. ( I7100d , b/150774014 )

• androidx.compose.ViewComposer has been moved to androidx.ui.node.UiComposer androidx.compose.Emittable has been removed. It was redundant with ComponentNode. androidx.compose.ViewAdapters has been removed. They are no longer a supported use case. Compose.composeInto has been deprecated. Use setContent or setViewContent instead. Compose.disposeComposition has been deprecated. Use the dispose method on the Composition returned by setContent instead. androidx.compose.Compose.subcomposeInto has moved to androidx.ui.core.subcomposeInto ComponentNode#emitInsertAt has been renamed to ComponentNode#insertAt ComponentNode#emitRemoveAt has been renamed to ComponentNode#removeAt ComponentNode#emitMode has been renamed to ComponentNode#move ( Idef00 )

• Created Image composable to handle sizing/layout in addition to drawing a given ImageAsset to the screen. This composable also supports drawing any arbitrary Painter instance respecting its intrinsic size as well as supporting a given fixed size or minimum size ( Ibcc8f )

• Deprecated Wrap composable. It can be replaced either with the LayoutAlign modifier or with the Stack composable ( Ib237f )

• WithConstraints got LayoutDirection parameter ( I6d6f7 )

• Made the layout direction be propagated from parent layout node to children. Added layout direction modifier. ( I3d955 )

• Stack component supports right-to-left directionality ( Ic9e00 )

• DrawShape composable was removed. Use DrawBackground modifier instead. ( I7ceb2 )

• Support right-to-left direction in LayoutPadding modifier ( I9e8da )

• Added AdapterList, a scrolling list component that only composes and lays out the visible items. Currently known issues include that it is vertical-only and does not fully handle all cases of changes to its children. ( Ib351b )

• Updated the ComposeFlags.COMPOSER_PARAM flag to be true , which will change the code generation strategy for the compose plugin. At a high level, this causes @Composable functions to be generated with an additional synthetic parameter, which is passed through to subsequent @Composable calls in order for the runtime to properly manage execution. This is a significant binary breaking change, however, should preserve source-level compatibility in all sanctioned usage of compose. ( I7971c )

• Added Canvas component. This composable takes up some size (provided by user) and allows you to draw using CanvasScope ( I0d622 )

• Density and DensityScope were merged into one interface. Instead of ambientDensity() you can now use DensityAmbient.current. Instead of withDensity(density) just with(density) ( I11cb1 )

• Changed LayoutCoordinates to make providedAlignmentLines a Set instead of a Map and have LayoutCoordinates implement the get() operator instead for retrieving a value. This makes it easier for modifiers to modify one or more value of the set without creating a new collection for each modifier. ( I0245a )

• Scrollers now exhibit native Android fling motion behavior. ( I922af , b/147493715 )

• Improvements to the API surface of Constraints ( I0fd15 )
