title: android explode transition doesn't explode GridView
body: <p>I am trying to use explode exit transition on a grid view. However, the only thing that flies away radially is the floating button at the bottom of the screen. The <code>GridView</code> cells slide away as a single unit. How do I make these cells "explode"?</p>
  
  <p>Here is my <code>style.xml</code> : </p>
  
  <pre><code>&lt;resources&gt;
  
      &lt;!-- Base application theme. --&gt;
      &lt;style name="AppTheme" parent="Theme.AppCompat.NoActionBar"&gt;
          &lt;!-- Customize your theme here. --&gt;
          &lt;item name="colorPrimary"&gt;@color/colorPrimary&lt;/item&gt;
          &lt;item name="colorPrimaryDark"&gt;@color/colorPrimaryDark&lt;/item&gt;
          &lt;item name="colorAccent"&gt;@color/colorAccent&lt;/item&gt;
          &lt;item name="colorControlActivated"&gt;@color/colorAccent&lt;/item&gt;
          &lt;item name="colorControlHighlight"&gt;@color/colorAccent&lt;/item&gt;
          &lt;item name="windowActionBar"&gt;false&lt;/item&gt;
          &lt;item name="windowNoTitle"&gt;true&lt;/item&gt;
          &lt;!-- Animation items --&gt;
          &lt;item name="android:windowActivityTransitions"&gt;true&lt;/item&gt;
          &lt;item name="android:windowContentTransitions"&gt;true&lt;/item&gt;
          &lt;item name="android:windowEnterTransition"&gt;@android:transition/fade&lt;/item&gt;
          &lt;item name="android:windowExitTransition"&gt;@android:transition/explode&lt;/item&gt;
      &lt;/style&gt;
  
  &lt;/resources&gt;
  </code></pre>
  
  <p>Here is the <code>onCreate</code> of the <code>GridView</code> activity that I am trying to explode : </p>
  
  <pre><code>protected void onCreate(Bundle savedInstanceState) {
          getWindow().requestFeature(Window.FEATURE_ACTIVITY_TRANSITIONS);
          super.onCreate(savedInstanceState);
          getWindow().setExitTransition(new Explode());
          setContentView(R.layout.activity_main);
  </code></pre>
  
  <p>Alternately, If you know of examples that contain <code>GridView</code> explode transitions please  feel free to post them.</p>
