title: Including animation resources
body: <p>Hey I've been trying to include two animations into a third animation for the sake of modularity.  I have a fade in animation in one file:</p>
  
  <pre><code>&lt;alpha xmlns:android="http://schemas.android.com/apk/res/android"
      android:fromAlpha="0.0"
      android:toAlpha="1.0"
      android:duration="1"
      android:fillAfter="true"&gt;
  &lt;/alpha&gt;
  </code></pre>
  
  <p>and a slide in animation in another file</p>
  
  <pre><code>&lt;translate xmlns:android="http://schemas.android.com/apk/res/android"
      android:fromXDelta="-50%"
      android:toXDelta="0"
      android:duration="1"&gt;
  &lt;/translate&gt;
  </code></pre>
  
  <p>I would like a third resource that just calls the two animations sequentially</p>
  
  <pre><code>&lt;!--psuedo code--&gt;
  &lt;set
      android:ordering="together"&gt;
      &lt;animation android:animation="@anim/fade_in"/&gt;
      &lt;animation android:animation="@anim/slide_in"/&gt;
  &lt;/set&gt;
  </code></pre>
  
  <p>Is there any way to do this?  Or do I have to create a set that contains all the animation properties that were defined in the previous files?</p>
