Drawable.ConstantState Class

Definition

This abstract class is used by Drawables to store shared constant state and data between Drawables.

Remarks

This abstract class is used by Drawables to store shared constant state and data between Drawables. BitmapDrawables created from the same resource will for instance share a unique bitmap stored in their ConstantState.

#newDrawable(Resources) can be used as a factory to create new Drawable instances from this ConstantState.

Use Drawable#getConstantState() to retrieve the ConstantState of a Drawable. Calling Drawable#mutate() on a Drawable should typically create a new ConstantState for that Drawable.

Constructors

Drawable.ConstantState()
Drawable.ConstantState(IntPtr, JniHandleOwnership)

A constructor used when creating managed representations of JNI objects; called by the runtime.
