title: Showing empty view when ListView is empty
body: <p>For some reason the empty view, a <em>TextView</em> in this case, always appears even when the <em>ListView</em> is not empty. I thought the <em>ListView</em> would automatically detect when to show the empty view.</p>
  
  <pre><code>&lt;RelativeLayout android:id="@+id/LinearLayoutAR"
      android:layout_height="fill_parent"
      android:layout_width="fill_parent"&gt;
      &lt;ListView android:id="@+id/ARListView"
          android:layout_width="fill_parent"
          android:layout_height="fill_parent"&gt;&lt;/ListView&gt;
      &lt;ProgressBar android:id="@+id/arProgressBar"
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          android:layout_centerHorizontal="true"
          android:layout_centerVertical="true"&gt;&lt;/ProgressBar&gt;
      &lt;!-- Here is the view to show if the list is emtpy --&gt;
      &lt;TextView android:id="@id/android:empty"
          android:layout_width="match_parent"
          android:layout_height="match_parent"
          android:text="No Results" /&gt;
  &lt;/RelativeLayout&gt;
  </code></pre>
  
  <p>How can I hook up the empty view properly?</p>
