import idv.hondadai.offlinemap.views.OfflineMapView;

import org.osmdroid.util.GeoPoint;
import org.osmdroid.views.MapController;
import org.osmdroid.views.MapView;

Using OfflineMapView to build your off-line map

MapView mapView = new OfflineMapView(this, "Your Database File's path");

Demo Code:

// init Layout
setContentView(R.layout.main);
this.mapLayout = (RelativeLayout) findViewById(R.id.mapLayout);

// init Offline Map
this.mapView = new OfflineMapView(this, "GoogleMapCH.sqlitedb");
this.mapController = mapView.getController();

// set Zoom Countrol
this.mapView.setBuiltInZoomControls(true);
// set Touch Control
this.mapView.setMultiTouchControls(true);
// zoom to 15
this.mapController.setZoom(15);
//add mapview
this.mapLayout.addView(this.mapView, new RelativeLayout.LayoutParams(
			android.view.ViewGroup.LayoutParams.FILL_PARENT,
			android.view.ViewGroup.LayoutParams.FILL_PARENT));

// scroll to 24082456, 120558472
GeoPoint geoPoint = new GeoPoint(24082456, 120558472);
this.mapController.setCenter(geoPoint);
