title: Contextual Actionbar with DialogFragment
body: <p>I've been trying to implement a contextual action bar along with a dialog fragment. 
  Similar to the downloads widget in android.</p>

  <p>I've tried to set <code>android:windowActionModeOverlay</code> to be true in the theme. </p>
  
  <p>But it doesnt seem to work.  Is there any way I can achieve it??</p>
