CompositeDrawable

This package is part of the Android support library which is no longer maintained. The support library has been superseded by AndroidX which is part of Jetpack. We recommend using the AndroidX libraries in all new projects. You should also consider migrating existing projects to AndroidX. To find the AndroidX class that maps to this deprecated class, see the AndroidX support library class mappings.

public class CompositeDrawable
extends Drawable implements Drawable.Callback

java.lang.Object
↳	android.graphics.drawable.Drawable
	↳	android.support.v17.leanback.graphics.CompositeDrawable

---

Generic drawable class that can be composed of multiple children. Whenever the bounds changes for this class, it updates those of its children.

Summary

Nested classes
class	CompositeDrawable.ChildDrawable Wrapper class holding a drawable object and BoundsRule to update drawable bounds when parent bound changes.
