В макете будет выглядеть так:

<com.example.yourpackage.RoundedLayout
    android:id="@+id/maplayout"
    android:layout_width="match_parent"
    android:layout_height="200dp"
    android:layout_margin="20dp">

    <fragment
        android:id="@+id/map"
        android:name="com.google.android.gms.maps.SupportMapFragment"
        android:layout_width="match_parent"
        android:layout_height="200dp"
        tools:context="com.example.yourpackage.MapsMarkerActivity"/>
</com.example.yourpackage.RoundedLayout>

В коде может быть как круглый, с рамкой :

    RoundedLayout rl = (RoundedLayout) findViewById(R.id.maplayout);
    rl.setShapeCircle(true);
    rl.showBorder(true);
    rl.setBorderWidth(2);

Этот макет можно использовать для формирования любого вида.

Невероятно, как Google не способен создавать полноценные демо-версии для API android.
