Here is my layout.

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

How can I hook up the empty view properly?

<RelativeLayout android:id="@+id/LinearLayoutAR"
            android:layout_height="fill_parent" android:layout_width="fill_parent">
            <ListView android:layout_width="fill_parent"
                android:layout_height="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android"
                android:id="@+id/ARListView"></ListView>
            <ProgressBar android:layout_width="wrap_content"
                android:layout_height="wrap_content" android:id="@+id/arProgressBar"
                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>
