title: Admob transparent in ListActivity
body: <p>AdView displays after a few seconds but it is transparent and listView is taking up whole screen.  Looked everywhere but cannot get Adview to behave.  Can you see what I am doing wrong so the ListView is making space for the Adview?</p>
  
  <pre><code>@Override
  protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      this.setContentView(R.layout.activity_with_adview);
  }
  </code></pre>
