title: Contextual action bar does not overlay my toolbar
body: <p>I have created an activity and set  toolbar as the actionbar which i have positioned at the bottom. </p>
  
  <p>Inside that activity, I have a listview that contain some data.</p>
  
  <p>Problem is, when I long press a list item, contextual action bar appears at the top instead of overlaying my toolbar which is positioned at the bottom.</p>
  
  <p><strong>my activity theme</strong></p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;resources&gt;
  &lt;!-- Base application theme. --&gt;
  &lt;style name="myActivityTheme" parent="Theme.AppCompat.Light.NoActionBar"&gt;
      &lt;item name="windowActionBar"&gt;false&lt;/item&gt;
      &lt;item name="android:windowActionModeOverlay"&gt;true&lt;/item&gt;
  &lt;/style&gt;
  </code></pre>
  
  <p></p>
  
  <p><strong>my toolbar</strong></p>
  
  <pre><code>&lt;android.support.v7.widget.Toolbar
      android:layout_width="fill_parent"
      android:layout_height="wrap_content"
      android:minHeight="?attr/actionBarSize"
      android:id="@+id/toorbar"
      android:background="@android:color/white"
      android:layout_gravity="bottom"&gt;
  &lt;/android.support.v7.widget.Toolbar&gt;
  </code></pre>
  
  <p><strong>my activity</strong></p>
  
  <pre><code>protected void onCreate(Bundle savedInstanceState){
      ToolBar toolbar =(ToolBar) findViewById(R.id.toolbar)
      setSupportActionBar(toolbar)
  }
  </code></pre>
  
  <p>What should i do to make CAB overlay my toolbar?</p>
  
  <p><strong>EDIT</strong></p>
  
  <p>This is <code>onCreateActionMode</code> method in my  class that handle long clicks</p>
  
  <pre><code>private class Selector implements AbsListView.MultiChoiceModeListener{
  
      @Override
      public boolean onCreateActionMode(android.view.ActionMode mode, Menu menu) {
          mode.getMenuInflater().inflate(R.menu.my_activity_menu,menu);
          toolbar.setVisibility(View.VISIBLE);
          return true;
      }
  </code></pre>
