title: Actionbar dropdown click event
body: <p>I have dropdown list in actionbar as navigation list. Using <strong>ActionBar.OnNavigationListener</strong> and <strong>onNavigationItemSelected</strong> to detect when user has clicked on item in actionbar dropdown navigation list and that works fine. </p>
  
  <p>However, <strong>onNavigationItemSelected</strong> is <strong>not called</strong> if user has clicked on the same item as the one which is currently selected in dropdown list! (I need this exact functionality behavior for app to work properly) </p>
  
  <p>So is there any way to detect click on any part of the dropdown list in actionbar? </p>
  
  <p>Is there a way to somehow reference dropdown view in actionbar, and then set onclicklistner on that dropdown object in actionbar. Like when we use dropdown list in standard layout?</p>
