public class CompositeDrawable
extends Drawable implements Drawable.Callback

java.lang.Object
↳	android.graphics.drawable.Drawable
	↳	androidx.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.
