Set Googlemapoptions For The Mapfragment Subclass

There is a method MapFragment.newInstance(options) The problem is that I have my own CustomMapFragment which is subclass of MapFragment and I don't see how I can set GoogleMapOpt

Solution 1:

So the correct solution was to look inside Android source code. After this I came up with this method:

publicstatic CustomMapFragment newInstance(GoogleMapOptions options) {
     CustomMapFragmentf=newCustomMapFragment();
     Bundleargs=newBundle();
     args.putParcelable(MAP_OPTIONS, options);
     f.setArguments(args);
     return f;
}

Solution 2:

You can use composition instead of inheritance (Composition vs inheritance) and come up with something like this:

publicclassMyMapFragmentextendsFragment {
    private MapFragment mapFragment; // google's map fragmentpublicMyMapFragment() {
        this.mapFragment = MapFragment.newInstance();
    }

    publicMyMapFragment(GoogleMapOptions options) {
        this.mapFragment = MapFragment.newInstance(options);
    }

    // delegate other methods to mapFragment
}
