TimeAnimator.TimeListener

public static interface TimeAnimator.TimeListener

androidx.core.animation.TimeAnimator.TimeListener


Implementors of this interface can set themselves as update listeners to a TimeAnimator instance to receive callbacks on every animation frame to receive the total time since the animator started and the delta time since the last frame. The first time the listener is called, deltaTime will be zero. The same is true for totalTime, unless the animator was set to a specific currentPlayTime prior to starting.

Summary

Public methods

abstract void onTimeUpdate(TimeAnimator animation, long totalTimeMs, long deltaTimeMs)

Notifies listeners of the occurrence of another frame of the animation, along with information about the elapsed time.
