title: Animate ImageView between two activities using shared element transitions with ChangeImageTransform
body: <p>I am trying to animate one ImageView to another position between two activities in Android API level 21. Since "MoveImage" in Android L Preview has been removed, I use "<a href="https://developer.android.com/reference/android/transition/ChangeImageTransform.html">ChangeImageTransform</a>" instead, but the sample code in documents doesn't work out (the two images animated separately).</p>
  
  <pre><code>&lt;transitionSet xmlns:android="http://schemas.android.com/apk/res/android"&gt;
      &lt;changeImageTransform&gt;
          &lt;targets&gt;
              &lt;target android:targetId="@id/ivA" /&gt;
              &lt;target android:targetId="@id/ivB" /&gt;
          &lt;/targets&gt;
      &lt;/changeImageTransform&gt;
  &lt;/transitionSet&gt;
  </code></pre>
  
  <p>Is there any working example? Thanks!</p>
