marker in the osm Map with osmdroid
提问by user1523001
I am trying to display a marquer in OSM, but can't. I can display the OSM map and the location of my phone, but nothing else.
我试图在 OSM 中显示一个标记，但不能。我可以显示 OSM 地图和我手机的位置，但不能显示其他任何内容。
Here is my code:
这是我的代码：
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
}
}

</activity>
</application>
I don't see how I can do that. Can somebody help me?
我不明白我怎么能做到这一点。有人可以帮助我吗？

Look at these lines of code:
看看这几行代码：
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);
I hope this will help you.
我希望这能帮到您。

add markerThey all ate as did :)
添加标记他们都像以前一样吃:)
working code:
工作代码：
public class mapcode extends Activity {
globalvar appState;

mapView = (MapView) this.findViewById(R.id.mapview);
mapView.setTileSource(TileSourceFactory.MAPNIK);
// mapView.setBuiltInZoomControls(true); //кнопка ZOOM +-
mapView.setMultiTouchControls(true);
mapController = this.mapView.getController();
mapController.setZoom(2);
this.mMyLocationOverlay = new SimpleLocationOverlay(this);

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