title: Remove icon/title for actionbar with expanded SearchView?
body: <p>I created a new project, targeting api 11 and above. I have an activity where I want a SearchView expanded by default:</p>
  
  <pre><code>@Override
  public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
      super.onCreateOptionsMenu(menu, inflater);
  
      inflater.inflate(R.menu.menu_search, menu);
      MenuItem searchItem = menu.findItem(R.id.action_search); 
      mSearchView = (SearchView) searchItem.getActionView();
      mSearchView.setIconifiedByDefault(false);
  }
  </code></pre>
  
  <p>which works, but I don't want any icon or title on the actionbar, just the searchview. I tried getting rid of my title and icon by doing:</p>
  
  <pre><code>getActionBar().setDisplayHomeAsUpEnabled(false);
  getActionBar().setDisplayShowTitleEnabled(false);
  getActionBar().setIcon(android.R.color.transparent);
  </code></pre>
  
  <p>But my actionbar still has this padding to the left of the searchview:</p>
  
  <p><img src="https://i.stack.imgur.com/otFh2.png" alt="enter image description here"></p>
  
  <p>Is there a way to get rid of it?</p>
  
  <p>Thanks</p>
  
  <p>-------- Edit --------------------</p>
  
  <p>Here's my activity in full:</p>
  
  <pre><code>public class GreatAndroid extends FragmentActivity {
      private SearchView mSearchView;
  
      @Override
      protected void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
  
          getActionBar().setDisplayShowHomeEnabled(false);
      }
  
      @Override
      public boolean onCreateOptionsMenu(Menu menu) {
          super.onCreateOptionsMenu(menu);
  
          getMenuInflater().inflate(R.menu.menu_search, menu);
          MenuItem mi = menu.findItem(R.id.action_search);
          mSearchView = (SearchView) mi.getActionView();
          mSearchView.setIconifiedByDefault(false);
  
          return true;
      }
  }
  </code></pre>
  
  <p>and here's the menu xml:</p>
  
  <pre><code>&lt;menu xmlns:android="http://schemas.android.com/apk/res/android"&gt;
     &lt;item android:id="@+id/action_search"
        android:title="@string/search"
        android:icon="@android:drawable/ic_menu_search"
        android:showAsAction="always"
        android:actionViewClass="android.widget.SearchView" /&gt;
  &lt;/menu&gt;
  </code></pre>
