extends ActionProvider
java.lang.Object | ||
↳ | android.view.ActionProvider | |
↳ | android.app.MediaRouteActionProvider |
The media route action provider displays a media route button
in the application's ActionBar
to allow the user to select routes and
to control the currently selected route.
The application must specify the kinds of routes that the user should be allowed
to select by specifying the route types with the setRouteTypes(int)
method.
Refer to MediaRouteButton
for a description of the button that will
appear in the action bar menu. Note that instead of disabling the button
when no routes are available, the action provider will instead make the
menu item invisible. In this way, the button will only be visible when it
is possible for the user to discover and select a matching route.

Public methods
isVisible
public boolean isVisible ()
If overridesItemVisibility()
returns true, the return value of this method
will help determine the visibility of the MenuItem
this ActionProvider is bound to.
If the MenuItem's visibility is explicitly set to false by the application, the MenuItem will not be shown, even if this method returns true.
Returns | |
---|---|
boolean |
true if the MenuItem this ActionProvider is bound to is visible, false if it is invisible. The default implementation returns true. |
onCreateActionView
public View onCreateActionView ()
This method is deprecated.
use onCreateActionView(android.view.MenuItem)
Factory method called by the Android framework to create new action views.
This method has been deprecated in favor of onCreateActionView(android.view.MenuItem)
.
Newer apps that wish to support platform versions prior to API 16 should also
implement this method to return a valid action view.
Returns | |
---|---|
View |
A new action view.
This value cannot be null . |
onCreateActionView
public View onCreateActionView (MenuItem item)
Factory method called by the Android framework to create new action views. This method returns a new action view for the given MenuItem.
If your ActionProvider implementation overrides the deprecated no-argument overload
onCreateActionView()
, overriding this method for devices running API 16 or later
is recommended but optional. The default implementation calls onCreateActionView()
for compatibility with applications written for older platform versions.
Parameters | |

MenuItem.OnMenuItemClickListener.onMenuItemClick
. -
Receiving a call to
Activity.onOptionsItemSelected(MenuItem)
-
Receiving a call to
Fragment.onOptionsItemSelected(MenuItem)
-
Launching the
Intent
set viaMenuItem.setIntent(android.content.Intent)
- Invoking this method.
The default implementation does not perform any action and returns false.
