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

Question

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 mat

Answer 1

Fastest (with less code lines) way i found:

ViewGroup.MarginLayoutParams parms = (ViewGroup.MarginLayoutParams) rlLocation.getLayoutParams();
    parms.bottomMargin = 100;
    parms.topMargin = 100;

Answer 2

You should not fix height of a map... set it according to screen height & width.

DisplayMetrics displaymetrics = new DisplayMetrics();
        getActivity().getWindowManager().getDefaultDisplay().getMetrics(displaymetrics);
        int height = displaymetrics.heightPixels;

        ViewGroup.LayoutParams params = mMapFragment.getView().getLayoutParams();
        params.height = height/2;
        mMapFragment.getView().setLayoutParams(params);

Answer 3

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);

this is an example using onConfigurationChanged() method :

@Override
public void onConfigurationChanged(Configuration newConfig) {
    super.onConfigurationChanged(newConfig);
    setContentView(R.layout.main);
    findViewById(R.id.storefront_map).getLayoutParams().width = 400;
}
