title: Event when searchview expands from iconified view
body: <p>What event(s) I should listen to determine when user clicks on iconified <a href="http://developer.android.com/reference/android/widget/SearchView.html" rel="noreferrer">SearchView</a>. I want to remove some items (ActionBar navigation tabs, if that is important) from action bar to make more space in portrait orientation.</p>
  
  <p>I've tried OnClickListener, OnFocusChangeListener, OnTouchListener and other events but neither gets triggered by SearchView expansion.</p>
