TimeAnimator

Class Overview

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

public void setTimeListener ( TimeAnimator.TimeListener listener)

Added in API level 16

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

Parameters

listener	the listener to be set.

public void start ()

Added in API level 16

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.
