Known Indirect Subclasses

AbsoluteSizeSpan, DynamicDrawableSpan, ImageSpan, LocaleSpan, MetricAffectingSpan, RelativeSizeSpan, ReplacementSpan, ScaleXSpan, StyleSpan, SubscriptSpan, SuperscriptSpan, TextAppearanceSpan, and 3 others.

AbsoluteSizeSpan	A span that changes the size of the text it's attached to.
DynamicDrawableSpan	Span that replaces the text it's attached to with a `Drawable` that can be aligned with the bottom or with the baseline of the surrounding text.
ImageSpan	Span that replaces the text it's attached to with a `Drawable` that can be aligned with the bottom or with the baseline of the surrounding text.
LocaleSpan	Changes the `Locale` of the text to which the span is attached.
MetricAffectingSpan	The classes that affect character-level text formatting in a way that changes the width or height of characters extend this class.
RelativeSizeSpan	Uniformly scales the size of the text to which it's attached by a certain proportion.
ReplacementSpan
ScaleXSpan	Scales horizontally the size of the text to which it's attached by a certain factor.
StyleSpan	Span that allows setting the style of the text it's attached to.
SubscriptSpan	The span that moves the position of the text baseline lower.
