<h3 id="view-prop-animator">Animating with ViewPropertyAnimator</h3>

<p>The {@link android.view.ViewPropertyAnimator} provides a simple way to animate several

properties of a {@link android.view.View} in parallel, using a single underlying {@link

android.animation.Animator}

object. It behaves much like an {@link android.animation.ObjectAnimator}, because it modifies the

actual values of the view's properties, but is more efficient when animating many properties at

once. In addition, the code for using the {@link android.view.ViewPropertyAnimator} is much

more concise and easier to read. The following code snippets show the differences in using multiple

{@link android.animation.ObjectAnimator} objects, a single

{@link android.animation.ObjectAnimator}, and the {@link android.view.ViewPropertyAnimator} when

simultaneously animating the <code>x</code> and <code>y</code> property of a view.</p>

<p><strong>Multiple ObjectAnimator objects</strong></p>

<pre>

ObjectAnimator animX = ObjectAnimator.ofFloat(myView, "x", 50f);

ObjectAnimator animY = ObjectAnimator.ofFloat(myView, "y", 100f);

AnimatorSet animSetXY = new AnimatorSet();

animSetXY.playTogether(animX, animY);

animSetXY.start();

</pre>

<p><strong>One ObjectAnimator</strong></p>

<pre>

PropertyValuesHolder pvhX = PropertyValuesHolder.ofFloat("x", 50f);

PropertyValuesHolder pvhY = PropertyValuesHolder.ofFloat("y", 100f);

ObjectAnimator.ofPropertyValuesHolder(myView, pvhX, pvyY).start();

</pre>

<p><strong>ViewPropertyAnimator</strong></p>

<pre>

myView.animate().x(50f).y(100f);

</pre>
