Bo basically it may be possible with the overlays but I have done it using RelativeLayout stuff 

<RelativeLayout
    android:id="@+id/headerlayout" 
    android:layout_width="fill_parent"
    android:layout_height="wrap_content" android:layout_alignParentTop="true"
    android:layout_alignParentLeft="true"
    >

    <Button android:id="@+id/amap_back_btn" android:layout_width="wrap_content"
        android:layout_height="wrap_content" android:layout_alignParentTop="true"
        android:layout_alignParentLeft="true" android:text="Back">
    </Button>

</RelativeLayout>

<MapViewActivity
    xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/mapview"
    android:layout_width="wrap_content" android:layout_height="wrap_content"
    android:clickable="true" android:apiKey="your map key"
    android:layout_below="@+id/headerlayout"
    android:layout_above="@+id/bottomlayout" 
    />

This is all If you find it correct dont forget to mark my answer as check. Best Regards,Anup

You will need to use an overlay to add the back button on the MapView. Have a look at this tutorial which explains on how to add overlays. http://www.anddev.org/viewtopic.php?t=92
