маркер на карте osm с osmdroid

Я пытаюсь отобразить маркер в OSM, но не могу. Я могу отобразить карту OSM и местоположение своего телефона, но больше ничего.

Вот мой код:

public class Carte2Activity extends Activity implements LocationListener {
    MapView mapView;
    MapController myMapController;
    MyLocationOverlay location = null;
    double lat;
    double lng;
    LocationManager lm;
    LocationListener ll;

    ArrayList<OverlayItem> anotherOverlayItemArray;
    String[] sources;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main); 
        mapView = (MapView)findViewById(R.id.openmapview);
        mapView.setBuiltInZoomControls(true);
        mapView.setMultiTouchControls(true);

        lm = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
        ll = new Myll();
        lm.requestLocationUpdates(LocationManager.GPS_PROVIDER,1000,0,ll);

        myMapController = mapView.getController();
        myMapController.setZoom(10);
        myMapController.setCenter(new GeoPoint((int)(48.785152*1E6), (int)(2.285156*1E6)));


        location = new MyLocationOverlay(getApplicationContext(), mapView);

       //ajouter la loc
        mapView.getOverlays().add(location);
        //afficher
        location.enableMyLocation();

    }      

    private class Myll implements LocationListener{

    public void onLocationChanged(Location location) {
        // TODO Auto-generated method stub
        lat = location.getLatitude();
        lng = location.getLongitude();
        run();
    }

    public void run() {
        // TODO Auto-generated method stub
        location.runOnFirstFix(new Runnable() { public void run() {
            mapView.getController().animateTo(location.getMyLocation());
            }}); 
    }

    public void onProviderDisabled(String provider) {
        // TODO Auto-generated method stub      
    }

    public void onProviderEnabled(String provider) {
        // TODO Auto-generated method stub      
    }

    public void onStatusChanged(String provider, int status, Bundle extras) {
        // TODO Auto-generated method stub      
    }
}

    public void onLocationChanged(Location location) {
        // TODO Auto-generated method stub      
    }

    public void onProviderDisabled(String provider) {
        // TODO Auto-generated method stub      
    }

    public void onProviderEnabled(String provider) {
        // TODO Auto-generated method stub      
    }

    public void onStatusChanged(String provider, int status, Bundle extras) {
        // TODO Auto-generated method stub

    }
}

            <category android:name="android.intent.category.LAUNCHER" />

    </activity>
</application>

I don't see how I can do that. Can somebody help me?

Посмотрите на эти строки кода:

        OverlayItem myLocationOverlayItem = new OverlayItem("Here", "Current Position", currentLocation);
        Drawable myCurrentLocationMarker = this.getResources().getDrawable(R.drawable.person);
        myLocationOverlayItem.setMarker(myCurrentLocationMarker);

        final ArrayList<OverlayItem> items = new ArrayList<OverlayItem>();
        items.add(myLocationOverlayItem);

        currentLocationOverlay = new ItemizedIconOverlay<OverlayItem>(items,
                new ItemizedIconOverlay.OnItemGestureListener<OverlayItem>() {
                    public boolean onItemSingleTapUp(final int index, final OverlayItem item) {
                        return true;
                    }
                    public boolean onItemLongPress(final int index, final OverlayItem item) {
                        return true;
                    }
                }, resourceProxy);
        this.mapView.getOverlays().add(this.currentLocationOverlay);

Я надеюсь, что это поможет вам.

Я получаю исключение nullpointer в этой строке: currentLocationOverlay = new ItemizedIconOverlay‹OverlayItem›(items, new ItemizedIconOverlay.OnItemGestureListener‹OverlayItem›() { public boolean onItemSingleTapUp(final int index, final OverlayItem item) { return true; } public boolean onItemLongPress( final int index, конечный элемент OverlayItem) { return true; } }, resourceProxy); - person user914425; 14.08.2015

добавить маркерОни все ели как и ели :)

рабочий код:

public class mapcode extends Activity {
    globalvar appState;
    int stats=0;
    private MapView mapView;

      //  mapView.setBuiltInZoomControls(true); //кнопка ZOOM +-
        mapView.setMultiTouchControls(true);

        mapController = this.mapView.getController();
        mapController.setZoom(2);

        this.mMyLocationOverlay = new SimpleLocationOverlay(this);                          
        this.mapView.getOverlays().add(mMyLocationOverlay);

        this.mScaleBarOverlay = new ScaleBarOverlay(this);                          
        this.mapView.getOverlays().add(mScaleBarOverlay);


        /////////////////
        resourceProxy = new DefaultResourceProxyImpl(getApplicationContext());
        GeoPoint  currentLocation = new GeoPoint(55.860863,37.115046);

        OverlayItem myLocationOverlayItem = new OverlayItem("Here", "Current Position", currentLocation);
        Drawable myCurrentLocationMarker = this.getResources().getDrawable(R.drawable.a);
