Integrating OSM MapView in fragments

As per asked in here... I am trying to implement OSM MapView in fragments. I've seen people done this in onCreateView

return new MapView(getActivity(), 256);

However I am not sure how to change my implementation of an Activity into Fragments... right now my Activity codes are like this:

MapView myOpenMapView;

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    mResourceProxy = new DefaultResourceProxyImpl(getApplicationContext());
    setContentView(R.layout.offline_map_activity);
    myOpenMapView = (MapView) findViewById(R.id.openmapview);
    myOpenMapView.getTileProvider().clearTileCache();

    //.... code continues
}

But I'm not sure how to convert this part of the code when implemented in Fragments:

setContentView(R.layout.offline_map_activity);
myOpenMapView = (MapView) findViewById(R.id.openmapview);

How do I instantiate the MapView object properly and return it in the onCreateView method?
