How to show empty view when ListView is empty?

Question

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>

Answer 1

it should be

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

take a close look at the id attribute
