title: Custom Translation Animation not working correctly
body: <p>I am attempting to animate a part of an android app, unfortunately I can not get my animation to work correctly. </p>
  
  <p>The following xml file works correctly, but it has an absolute reference rather than a relative one.</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;objectAnimator xmlns:android="http://schemas.android.com/apk/res/android" 
          android:propertyName="x" 
          android:valueType="floatType"
          android:valueTo="0" 
          android:valueFrom="100"
          android:duration="800"
  /&gt;
  </code></pre>
  
  <p>When I try a a relative reference, like the following, the animation is not correct. It produces the correct screen, but the fragment just appears, rather than sliding in from the left.</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;objectAnimator xmlns:android="http://schemas.android.com/apk/res/android"
      android:propertyName="translationX" 
      android:fromXDelta="100%"
      android:toXDelta="0%"
      android:duration="500"/&gt;
  </code></pre>
  
  <p>Does anyone have the solution to this?</p>
