title: ProgressBar in ActionBar
body: <p>When trying to show the ProgressBar in the ActionBar it doesn't work. This is what I've done. Is there something else I need to do that people aren't mentioning because it's so simple? Is there something I need to do with my ActionBar?</p>
  
  <p>In the activity:</p>
  
  <pre><code>super.onCreate(savedInstanceState);
  requestWindowFeature(Window.FEATURE_INDETERMINATE_PROGRESS);
  setContentView(R.layout.activity_movie_grid);
  </code></pre>
  
  <p>As far as I know, that alone should display the ProgressBar. Then to toggle it I can run one of these commands from the fragment:</p>
  
  <pre><code>getActivity().setProgressBarIndeterminate(true);
  getActivity().setProgressBarIndeterminate(false);
  </code></pre>
  
  <p>I've looked at other posts but there's nothing else mentioned. I'm not using the support version.</p>
  
  <p>The only other things in the ActionBar are an up arrow, title, and searchView; there's plenty of space.</p>
  
  <p>I'm assuming I don't need to create an ActionBar in XML or pragmatically and that this one command is all that's required. Is there anything else I'm supposed to do? Any other info you want me to provide?</p>
