Since <code>ViewPropertyAnimator</code> is only good for simple animations, use more advanced <code>ObjectAnimator</code> class - basically method <a href="http://developer.android.com/reference/android/animation/ValueAnimator.html#setRepeatCount(int)">setRepeatCount</a> and additionally <a href="http://developer.android.com/reference/android/animation/ValueAnimator.html#setRepeatMode(int)">setRepeatMode</a>.

This is actually possible. Here's an example of rotating a view:

<pre><code> final ViewPropertyAnimator animator = view.animate().rotation(360).setInterpolator(new LinearInterpolator()).setDuration(1000);

 animator.setListener(new android.animation.Animator.AnimatorListener() {
 ...

 @Override
 public void onAnimationEnd(final android.animation.Animator animation) {
 animation.setListener(null);
 view.setRotation(0);
 view.animate().rotation(360).setInterpolator(new LinearInterpolator()).setDuration(1000).setListener(this).start();
 }

 });
</code></pre>

You can also use "<a href="http://developer.android.com/reference/android/view/ViewPropertyAnimator.html#withEndAction(java.lang.Runnable)" rel="noreferrer">withEndAction</a>" instead of a listener.

blocks|key|2183404|text|您可以使用CycleInterpolator。例如，如下所示：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|2183405|++++int+durationMs+=+60000;
++++int+cycleDurationMs+=+1000;
++++view.setAlpha(0f);
++++view.animate().alpha(1f)
++++++++++++.setInterpolator(new+CycleInterpolator(durationMs+/+cycleDurationMs))
++++++++++++.setDuration(durationMs)
++++++++++++.start();|code-block|syntax|javascript|2183406|entityMap^0|5|H|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@$9|N|A|O|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|P|8|@]|D|@]|E|$I|J]]|$1|K|3|-4|5|6|7|Q|8|@]|D|@]|E|$]]]|L|$]]

You can use <code>CycleInterpolator</code>. For example, like this:

<pre><code> int durationMs = 60000;
 int cycleDurationMs = 1000;
 view.setAlpha(0f);
 view.animate().alpha(1f)
 .setInterpolator(new CycleInterpolator(durationMs / cycleDurationMs))
 .setDuration(durationMs)
 .start();
</code></pre>

blocks|key|5236564|text|下面是一个用Kotlin编写的示例，它提供了一种简单的方法，可以通过在withEndAction中递归调用来重复动画|type|unstyled|depth|inlineStyleRanges|entityRanges|data|5236565|示例|5236566|private+var+animationCount+=+0

private+fun+gyrate()+{

++++animate().scaleX(scale).scaleY(scale).setDuration(725).withEndAction(::gyrate)
}|code-block|syntax|javascript|5236567|这重复地使视图的大小变得更小，返回正常，变小，返回正常，等等。这是一个非常简单的模式，可以重复任何你想要的动画。|5236568|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|N|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|O|8|@]|9|@]|A|$G|H]]|$1|I|3|J|5|6|7|P|8|@]|9|@]|A|$]]|$1|K|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|L|$]]

Here is an example in Kotlin with a simple way to repeat the animation by recursively calling it in withEndAction
Example
<pre><code>private var animationCount = 0

private fun gyrate() {
 val scale = if (animationCount++ % 2 == 0) 0.92f else 1f
 animate().scaleX(scale).scaleY(scale).setDuration(725).withEndAction(::gyrate)
}
</code></pre>
This repeatedly animates the size of a view to get smaller, return to normal, get smaller, return to normal, etc. This is a pretty simple pattern to repeat whatever animation you'd like.

blocks|key|268789|text|在kotlin中，你可以这样做。创建一个runnable。在它内部，动画视图并将withEndAction设置为runnable本身。并在结束时运行runnable到动画开始。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|268790|var+runnable:+Runnable?+=+null

in kotlin you can do it like this. create a runnable. inside it animate the view and set <code>withEndAction</code> to runnable itself. and at the end run runnable to animation start.
<pre class="lang-kotlin prettyprint-override"><code>var runnable: Runnable? = null
runnable = Runnable {
 view.animate()
 .setDuration(10000)
 .rotationBy(360F)
 .setInterpolator(LinearInterpolator())
 .withEndAction(runnable)
 .start()
}
runnable.run()

I'm doing an animation of bubbles on the screen, but the bubbles stop after finishing the animation time. How do I repeat the animation or make it infinite?

<pre><code>bub.animate();
bub.animate().x(x2).y(y2);
bub.animate().setDuration(animationTime); 
bub.animate().setListener(new AnimatorListenerAdapter() {

 @Override
 public void onAnimationStart(Animator animation) {
 animators.add(animation); 
 } 

 @Override
 public void onAnimationRepeat(Animator animation) {
 }

 @Override
 public void onAnimationEnd(Animator animation) {
 }
});
</code></pre>

How can I repeat a property animation?
