title: Show DialogFragment with animation growing from a point
body: <p>I'm showing a <code>DialogFragment</code> when the user taps on a row in a <code>ListView</code>. I'd like to animate the showing of the dialog so that it grows from the center of the row. A similar effect can be seen when opening a folder from the launcher.</p>
  
  <p>One idea that I've had is a combination of <code>TranslateAnimation</code> and <code>ScaleAnimation</code>. Is there another way?</p>
