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?

As appsthatmatter says, in the layout something like:

<ListView android:id="@+id/listView" ... />
<TextView android:id="@+id/emptyElement" ... />

and in the linked Activity: 

this.listView = (ListView) findViewById(R.id.listView);
this.listView.setEmptyView(findViewById(R.id.emptyElement));

Does also work with a GridView...

A programmatically solution will be:

TextView textView = new TextView(context);
textView.setId(android.R.id.empty);
textView.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT));
textView.setText("No result found");
listView.setEmptyView(textView);
