title: Overlay Android AlertDialog with a View (Button)
body: <p>I have created an AlertDialog (like below) and would like to display a View (floating action button from library) over it.</p>
  
  <pre><code>new AlertDialog.Builder(getActivity())
      .setTitle("Last Day of School Description")
  .setMessage(...)
  .show();
  </code></pre>
  
  <p>It currently looks like this, but the dialog overlays the button. I want the button to be above the AlertDialog and clickable as well.

  My FloatingActonButton object is called "fab".</p>
