title: Reset action bar after using SearchView
body: <p>I'm using <code>SearchView</code> widget to enable searching in my app. After the initial click on the search icon, the <code>SearchView</code> widget expands into the search field and the "back" arrow is shown next to the application icon. If I click the application icon the action bar reverts to the initial state (no "back" arrow) and the <code>SearchView</code> reverts back to icon.</p>
  
  <p>Now the problem: after the search is executed the action bar doesn't change, the only way to revert is to click the application icon or phone's "back" arrow. Not good since I want the action bar go to the initial state when the search is done. I tried <code>SearchView.setIconofied(true)</code> but there are 2 problems:</p>
  
  <ol>
  <li>Search icon appears at the same spot as the edit field (originally it's on the far right).</li>
  <li>Action bar still displays "back" arrow.</li>
  </ol>
  
  <p>I think the problem I'm facing results from deviating from the regular navigation pattern. In my case everything is happening inside the same activity (search results are displayed in the same activity that hosts the action bar), so for example executing <code>Activity.finish()</code> simply makes app exit.</p>
  
  <p>How do I trigger "go back one step" of the action bar? Or simulate click on the application icon?</p>
