title: Show dropdown programmatically in ActionBar / ActionBarSherlock
body: <p>I have an activity using <code>ActionBarSherlock</code> with <code>ActionBar.NAVIGATION_MODE_LIST</code>.</p>
  
  <p>When entering the page I want the spinner in the action bar to expand programmatically after it's populated with items so the user needs to pick an item. As of now the first item in the adapter is selected automatically.</p>
  
  <p>I can't figure out a nice way to expand the spinner in the action bar programmatically. Do I need to use a custom view to achieve this behavior?</p>
  
  <p>I've looked on the action bar with the <code>HierarchyViewer</code> and the spinner does not have an id set. Any ideas?</p>
