title: Android SearchView.OnQueryTextListener OnQueryTextSubmit not fired on empty query string
body: <p>I am using <strong>Android 4.1.2</strong>. I have a <code>SearchView</code> widget on an <code>ActionBar</code>. Documentation on <code>SearchView.OnQueryTextListener</code> from the android developer site states that <code>onQueryTextSubmit</code> is fired/Called when the user submits the query. This could be due to a keypress on the keyboard or due to pressing a submit button."</p>
  
  <p>This does not happen if the search query is empty. I need this to fire on an empty query to clear the search filter of a ListView. Is this a bug or am I doing something wrong?</p>
