title: Change text color of search hint in actionbar using support library
body: <p>I want to change the text color of search view hint, but I tried in many ways with no success.
  Like in this post: <a href="https://stackoverflow.com/questions/17791388/changing-action-bar-searchview-hint-text-color">Changing action bar searchview hint text color</a></p>
  
  <p>I'm using Appcompat, support library of actionbar.</p>
  
  <p>I tried this with null pointer return:</p>
  
  <pre><code>AutoCompleteTextView searchText = (AutoCompleteTextView) searchView.findViewById(R.id.abs__search_src_text);
  searchView.findViewById(R.id.abs__search_src_text);
  searchText.setHintTextColor(getResources().getColor(R.color.white));
  searchText.setTextColor(getResources().getColor(R.color.white)); 
  </code></pre>
