Add buttons to a listactivity

Question

I have a layout for a ListActivity. To modify the list I have used menu-options. But to remove a couple of \"clicks\" on the screen I\'d like to add two buttons in the butto

From http://developer.android.com/reference/android/app/ListActivity.html:

“ListActivity has a default layout that consists of a single, full-screen list in the center of the screen. However, if you desire, you can customize the screen layout by setting your own view layout with setContentView() in onCreate(). To do this, your own view MUST contain a ListView object with the id "@android:id/list"”

EDIT: here is an example:

The ListActivity may be created like this:

public class ListViewTest extends ListActivity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        String[] values = {"One", "Two", "Three"};

        setListAdapter(new ArrayAdapter(this, android.R.layout.simple_list_item_1, values));

        setContentView(R.layout.main);
    }
}

The main.xml layout is as follows:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">

    <ListView 
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_weight="1" 
        android:id="@android:id/list"></ListView>
    <Button 
        android:layout_width="wrap_content" 
        android:layout_height="wrap_content" 
        android:layout_gravity="center_horizontal"
        android:text="Test button" 
        android:id="@+id/TestButton"></Button>
</LinearLayout>
