title: SearchView edittext is always null
body: <p>I always get that textView is null when doing this:</p>
  
  <pre><code>public boolean onCreateOptionsMenu(Menu menu) {
  
          getMenuInflater().inflate(R.menu.main, menu);
  
          MenuItem searchItem = menu.findItem(R.id.action_search);
          SearchView searchView = (SearchView) MenuItemCompat
                  .getActionView(searchItem);
  
          int id = searchView.getContext().getResources().getIdentifier("android:id/search_src_text", null, null);
          TextView textView = (TextView) searchView.findViewById(id);
          textView.setTextColor(Color.WHITE);
  }
  </code></pre>
  
  <p>Anyone know why?</p>
