перемещение карты в представлении карты из одного места в другое в Android

Попробуйте этот класс, просто передайте Activity act,GeoPoint src,GeoPoint dest, int color, MapView mMapView

To call this class do this

    new getRoute().DrawPath(this,mGeoPoint,getGeoPoint,Color.RED,mMapView);  





  public class getRoute 
    {
        /*Variable*/
        double mIntentLatitude, mIntentLongitude;
        double mCursorLatitude, mCursorLongitude, mStartLatitude, mStartLongitude, mEndLatitude, MEndLongitude;
        String mJsonData;
        String mEnd_Address, mStart_Address, mName;
        int mLength;
        GeoPoint mGeoPoint = new GeoPoint(220328269, 725588202);
        double mLatitude_End[], mLongitude_End[], mLatitude_Start[], mLongitude_Start[];
        Activity activity;

            draw.execute("Draw");
        }

Попробуйте это, если вы хотите переместить карту в определенную позицию, затем получите широту или долготу этой позиции и просто передайте это:

MapController mMapController;

mMapController=mMapView.getController();
    mMapController.setCenter(new GeoPoint((int)(lat * 1E6), (int)(lon * 1E6)));

и если вы хотите нарисовать путь между двумя местоположениями, просто передайте lat и lon в этом:

Intent intent = new Intent(android.content.Intent.ACTION_VIEW, 
                Uri.parse("http://maps.google.com/maps?saddr="+ String.valueOf(from_lattitude) +","+ String.valueOf(from_longitude) +"&daddr="+ String.valueOf(dest_lati) +","+ String.valueOf(dest_longi)));
                startActivity(intent);
