TimeAnimator

public class TimeAnimator
extends ValueAnimator

java.lang.Object
↳	android.animation.Animator
	↳	android.animation.ValueAnimator
		↳	android.animation.TimeAnimator

This class provides a simple callback mechanism to listeners that is synchronized with all other animators in the system. There is no duration, interpolation, or object value-setting with this Animator. Instead, it is simply started, after which it proceeds to send out events on every animation frame to its TimeListener (if set), with information about this animator, the total elapsed time, and the elapsed time since the previous animation frame.

Summary

Nested classes
`interface`	`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.

Public methods

setCurrentPlayTime

Added in API level 16

void setCurrentPlayTime (long playTime)

Sets the position of the animation to the specified point in time. This time should be between 0 and the total duration of the animation, including any repetition. If the animation has not yet been started, then it will not advance forward after it is set to this time; it will simply set the time to this value and perform any appropriate actions based on that time. If the animation is already running, then setCurrentPlayTime() will set the current playing time to this value and continue playing from that point.

Parameters
`playTime`	`long`: The time, in milliseconds, to which the animation is advanced or rewound.

setTimeListener

Added in API level 16

void setTimeListener (TimeAnimator.TimeListener listener)

Sets a listener that is sent update events throughout the life of an animation.

Parameters
`listener`	`TimeAnimator.TimeListener`: the listener to be set.

start

Added in API level 16

void start ()

Starts this animation. If the animation has a nonzero startDelay, the animation will start running after that delay elapses. A non-delayed animation will have its initial value(s) set immediately, followed by calls to onAnimationStart(Animator) for any listeners of this animator.

The animation started by calling this method will be run on the thread that called this method. This thread should have a Looper on it (a runtime exception will be thrown if this is not the case). Also, if the animation will animate properties of objects in the view hierarchy, then the calling thread should be the UI thread for that view hierarchy.
