Try this

public class MyMap extends MapActivity{

    MapView mapView;
    MapController mapController;

    /* positon */
    double latitude = Your latitude; 
    double longitude = Your longitude;

    @Override
    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);
        setContentView(R.layout.YourLayout);

        mapView = (MapView) findViewById(R.id.mapview);
        mapView.setBuiltInZoomControls(true);
        mapView.setSatellite(true);

        mapController = mapView.getController();
        mapController.setZoom(8); 
        GeoPoint pointRabat = new GeoPoint(microDegres(latitude),
                microDegres(longitude));
        mapController.setCenter(pointRabat);
    }

    private int microDegres(double value) {
        return (int) (value * 1000000);
    }

@Override
    protected boolean isRouteDisplayed() {
        return false;
    }

}

for add overlay

public void onLocationChanged(Location loc) {
        // TODO Auto-generated method stub
       GeoPoint pointRabat = new GeoPoint(microDegres(latitude),
                    microDegres(longitude));
        OverlayItem overlayitem = new OverlayItem(point, "My Current Location", "My Current Location");
        overlay.addOverlay(overlayitem);
        mapOverlays.add(overlay);

    }
