title: Up ActionBar action on DialogFragment
body: <p>I have a <code>DialogFragment</code> that is styled to full screen using <code>setStyle(STYLE_NORMAL, R.style.Theme_App)</code>. </p>
  
  <p>The <code>DialogFragment</code> shows fine but the up action (the <code>homeAsUp</code> action on the ActionBar) does not work. I tried implementing <code>onOptionsItemSelected</code> in the <code>DialogFragment</code> but it is never called.</p>
  
  <p>Is there a way to get the up action callback in the DialogFragment so I can dismiss it ? For reference, I'm using <code>ActionBarCompat</code>.</p>
