Class BitmapContainerCrossFadeFactory<T>

java.lang.Object

com.bumptech.glide.request.animation.BitmapContainerCrossFadeFactory<T>

Type Parameters:

T - The type of the composite object that contains the Bitmap to be animated.

All Implemented Interfaces:

GlideAnimationFactory<T>

Direct Known Subclasses:

BitmapCrossFadeFactory

public abstract class BitmapContainerCrossFadeFactory<T>
extends Object
implements GlideAnimationFactory<T>

A cross fade GlideAnimation for complex types that have a Bitmap inside that uses an TransitionDrawable to transition from an existing drawable already visible on the target to the new bitmap. If no existing drawable exists, this class can instead fall back to a default animation that doesn't rely on TransitionDrawable. The new bitmap queried from the complex type is wrapped in a BitmapDrawable.
