Class AnimationHandler

java.lang.Object

icyllis.modernui.animation.AnimationHandler

@Internal
public class AnimationHandler
extends Object

This custom, static handler handles the timing pulse that is shared by all active ValueAnimators. This approach ensures that the setting of animation values will happen on the same thread that animations start on, and that all animations will share the same times for calculating their values, which makes synchronizing animations possible.
