title: Animate a TextView to slide off the screen
body: <p>I'm animating a TextView with this code:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;set xmlns:android="http://schemas.android.com/apk/res/android" &gt;
  
      &lt;translate
          android:duration="1000"
          android:toYDelta="100%"
          android:fromYDelta="0%" /&gt;
  
  &lt;/set&gt;
  </code></pre>
  
  <p>and doing this:</p>
  
  <pre><code>textView.startAnimation(slideOutAnim);
  </code></pre>
  
  <p>But this code only makes the TextView animate about 1/4 of the screen length. What should I set the toYDelta to so that it ensures that the TextView is out of the screen? I know I could just set it to a really high number but is there a more efficient/effective way to get this done? Thanks</p>
