How to make map rotate instead of my current location marker osmdroid

I'm writing an android app that uses osmdroid. Right now the map displays and my current location marker (the triangle) rotates on top of the map. Instead of this I would like the MAP to rotate and the current location triangle marker to be locked in one position like a typical car GPS. This is my current code.

public class MainActivity extends Activity {

protected static final String PROVIDER_NAME = LocationManager.GPS_PROVIDER;
public static final GeoPoint SCHOOL = new GeoPoint(33.989820, -81.029123);

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    MapView mapView = (MapView) findViewById(R.id.mapview);
    mapView.setClickable(true);
    mapView.setBuiltInZoomControls(true);
    mapView.setMultiTouchControls(true);
    mapView.setUseDataConnection(true);
    //mapView.setMapOrientation(0);
    mapView.setTileSource(TileSourceFactory.MAPQUESTOSM);

    MyLocationNewOverlay myLocationOverlay = new MyLocationNewOverlay(getApplicationContext(), mapView);
    myLocationOverlay.enableMyLocation();
    myLocationOverlay.enableFollowLocation();

    mapView.getOverlays().add(myLocationOverlay);
    IMapController mapViewController = mapView.getController();
    mapViewController.setZoom(16);
   }

}

Any ideas on what needs to be fixed/added?

Use this instead default MyLocationNewOverlay:

class LocationOverlay(map: MapView) : MyLocationNewOverlay(map) {
    override fun drawMyLocation(canvas: Canvas?, pj: Projection?, lastFix: Location?) {
        if (this.isFollowLocationEnabled) rotateMap(lastFix)
        super.drawMyLocation(canvas, pj, lastFix)
    }

    private fun rotateMap(lastFix: Location?) {
        lastFix?.let {
            if (it.speed > 0.2) {
                mMapView.mapOrientation = -it.bearing
            }
        }
    }
}

The behaviour you want is implemented in OSMNavigator MapActivity, using: DirectedLocationOverlay, and LocationListener. Have a look.
