abstract class DrawableContainerState : Drawable.ConstantState

kotlin.Any
↳	android.graphics.drawable.Drawable.ConstantState
	↳	android.graphics.drawable.DrawableContainer.DrawableContainerState

A ConstantState that can contain several Drawables. This class was made public to enable testing, and its visibility may change in a future release.

Inherited functions

From class ConstantState Drawable newDrawable() Creates a new Drawable instance from its constant state. Note: Using this method means density-dependent properties, such as pixel dimensions or bitmap images, will not be updated to match the density of the target display. To ensure correct scaling, use newDrawable(android.content.res.Resources) instead to provide an appropriate Resources object. Drawable newDrawable(res: Resources?) Creates a new Drawable instance from its constant state using the specified resources. This method should be implemented for drawables that have density-dependent properties. The default implementation for this method calls through to newDrawable(). Drawable newDrawable(res: Resources?, theme: Resources.Theme?) Creates a new Drawable instance from its constant state using the specified resources and theme. This method should be implemented for drawables that have theme-dependent properties. The default implementation for this method calls through to newDrawable(android.content.res.Resources).
