android - How do you programmatically change the width & height of Google Maps v2 (support Fragment)?

How do you programatically change the width and height of a com.google.android.gms.maps.SupportMapFragment? I'd imagine you might be able to wrap it in a viewgroup with match_parent, but I'm hoping not to nest if I don't have to (honestly not even sure it works).

 <fragment xmlns:android="http://schemas.android.com/apk/res/android"
                    android:id="@+id/storefront_map"
                    class="com.google.android.gms.maps.SupportMapFragment"
                    android:layout_width="match_parent"
                    android:layout_height="250dp"
                    />

To give context, I'd like to expand the map from one height to another on map click.

mMap.setOnMapClickListener(new GoogleMap.OnMapClickListener() {
    @Override
    public void onMapClick(LatLng latLng) {
       expandMap(); // not sure how to do this programatically.
    }
});

Any help would be great!

I figured it out largely with the help of Programmatically set google map fragment visibility (API2).

mMapFragment = (SupportMapFragment) (getSupportFragmentManager()
            .findFragmentById(R.id.storefront_map));
ViewGroup.LayoutParams params = mMapFragment.getView().getLayoutParams();
params.height = 900;
mMapFragment.getView().setLayoutParams(params);
