title: Android: scale animation does not work when direction is changed
body: <p>In my Android app, I hava a scale animation.</p>
  
  <pre><code>&lt;set xmlns:android="http://schemas.android.com/apk/res/android"   android:interpolator="@android:anim/accelerate_interpolator"   android:fillEnabled="true"  android:fillAfter="true"  &gt;
   &lt;scale android:fromXScale="1.0" android:toXScale="0.0"   android:fromYScale="1.0"    android:toYScale="1.0"      android:duration="32000"   /&gt;
   &lt;/set&gt;
  </code></pre>
  
  <p>it works fine. it scales the view from left to right. but I need to scale from right to left. so when I modify the <code>fromXScale="-1.0"</code>, the animation does not happen and the view is scaled instantly without animation.
  My animation xml for the reverse direction is given below: </p>
  
  <pre><code> &lt;set xmlns:android="http://schemas.android.com/apk/res/android"   android:interpolator="@android:anim/accelerate_interpolator"   android:fillEnabled="true"  android:fillAfter="true"  &gt;            
    &lt;scale android:fromXScale="-1.0" android:toXScale="0.0"   android:fromYScale="1.0"    android:toYScale="1.0"      android:duration="32000"   /&gt; 
   &lt;/set&gt;
  </code></pre>
  
  <p>How can I animate the View from reverse direction? what is wrong with my code?                                           </p>
