title: AppCompat SearchView icon can't be GONE
body: <p><img src="https://i.stack.imgur.com/HvE3u.png" alt="SearchView icon"></p>
  
  <p>I'm using android.support.v7.widget.SearchView and i need to make this search icon GONE.
  I have custom ActionBar layout with SearchView:</p>
  
  <pre><code>        &lt;android.support.v7.widget.SearchView
          android:id="@+id/search"
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          android:visibility="gone"/&gt;
  </code></pre>
  
  <p>initialize SearchView :</p>
  
  <pre><code>    searchView = (SearchView) findViewById(R.id.search);
  
      AutoCompleteTextView searchText = (AutoCompleteTextView) searchView.findViewById(R.id.search_src_text);
      searchText.setPadding(0, 0, 0, -padding);
      searchText.setHintTextColor(getResources().getColor(R.color.light_gray));
  
      View searchPlate = searchView.findViewById(R.id.search_plate);
      searchPlate.setBackgroundResource(R.drawable.searchview_textfield);
  
      View close = searchPlate.findViewById(R.id.search_close_btn);
      close.setBackgroundResource(R.drawable.selectable_background_orange);
  </code></pre>
  
  <p>I was trying to customize searchIcon like this:</p>
  
  <pre><code>ImageView icon = (ImageView)searchView.findViewById(android.support.v7.appcompat.R.id.search_mag_icon);
  </code></pre>
  
  <p>trying to set everything from here <a href="https://stackoverflow.com/a/21080023/2281717">Android SearchView Icon</a> but it's not that ImageView. 
  Can anyone help me plz?</p>
