here is the xml layout which I use...

```
<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >

<fragment
        android:id="@+id/map"
        android:layout_width="251dp"
        android:layout_height="174dp"
        android:layout_gravity="center"
        android:layout_marginLeft="20dp"
        android:layout_marginRight="20dp"
        android:layout_marginTop="20dp"
        class="com.google.android.gms.maps.MapFragment" />

   <ListView
      android:id="@+id/tips"
      android:layout_width="match_parent"
      android:layout_height="0dp"
      android:layout_marginBottom="20dp"
      android:layout_marginLeft="20dp"
      android:layout_marginRight="20dp"
      android:layout_weight="1.64"
      android:clickable="false"
      android:focusable="false"
      android:focusableInTouchMode="false"
      android:listSelector="@android:color/transparent" >
   </ListView>
 </LinearLayout>
