title: Put a progressBar on ActionBar
body: <p>I am trying to put an indeterminate ProgressBar on the actionBar. I was using an actionView to put the progressBar like Google+ app for example.</p>
  
  <pre><code>&lt;item
      android:id="@+id/menu_progress"
      android:actionLayout="@layout/action_progress"
      android:menuCategory="container"
      android:showAsAction="always"&gt;
  &lt;/item&gt;
  </code></pre>
  
  <p>the problem is that the progress bar is considered as an item and therefore on a Nexus S portrait mode I have only one other item on the actionbar while on Google+ I can see two items plus the progressBar. 
  How is it possible to put a progressbar using the android actionbar?</p>
