You will need to add a component on top of it. Here's a simple solution with a supplied arch image to cover part of the list. You will need to supply your own arch image.

Code:

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

<ListView
  android:id="@+id/list"
  android:layout_width="match_parent"
  android:layout_height="match_parent"> 
</ListView>

<ImageView
    android:id="@+id/imageView1"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:scaleType="fitXY"
    android:src="@drawable/arch" />

 </RelativeLayout>
