Showing empty view when ListView is empty

For some reason the empty view, a TextView in this case, always appears even when the ListView is not empty. I thought the ListView would automatically detect when to show the empty view.

<RelativeLayout android:id="@+id/LinearLayoutAR"
android:layout_height="fill_parent"
android:layout_width="fill_parent">
<ListView android:id="@+id/ARListView"
android:layout_width="fill_parent"
android:layout_height="fill_parent"></ListView>
<ProgressBar android:id="@+id/arProgressBar"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"></ProgressBar>
<!-- Here is the view to show if the list is emtpy -->
<TextView android:id="@id/android:empty"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:text="No Results" />
</RelativeLayout>


How can I hook up the empty view properly?

Answer

It should be:

<TextView android:id="@android:id/empty"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:text="No Results" />

Note the id attribute.
