body: <p><img src="https://i.stack.imgur.com/d4Hot.png" alt="enter image description here"></p>
  
  <p>I was trying to create an <a href="http://developer.android.com/training/search/setup.html" rel="noreferrer">action bar search</a> in my application, but in the expanded state the <a href="http://developer.android.com/reference/android/widget/SearchView.html" rel="noreferrer">SearchView</a> is not taking the entire action bar width( it is still showing other actions)!</p>
  
  <p>So, how to make the SearchView fill the full ActionBar Area (as in GMAIL app)?   </p>
