title: Doing animation on "hidden" Activity
body: <p>I have been working on trying to get an Activity to not show until data has been selected and is ready for display: <a href="https://stackoverflow.com/questions/11827480/prevent-screen-display-until-after-fetching-data">Prevent screen display until after fetching data</a></p>
  
  <p>Finally got it to work with the aid of themes.</p>
  
  <p>Now I have another problem.</p>
  
  <p>I need to animate the transition from one Activity to the next.
  I know how to use overridePendingTransition but this won't work here since I am already in the target Activity when I want to do the animation.
  The only reason I can see the other one is because the current one is transparent.</p>
  
  <p>I have no problem sliding in the new one:</p>
  
  <pre><code>    View view = getLayoutInflater().inflate(R.layout.content_screen, null);
      view.startAnimation(AnimationUtils.loadAnimation(this, R.anim.slide_in_right));
      setContentView(view);
  </code></pre>
  
  <p>However, I can't think of any way to get the old one to slide out.</p>
  
  <p>Any ideas anyone?</p>
