我试图在OSM中展示一个品牌，但不能。我可以显示OSM地图和手机的位置，但没有别的。
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
}
}
androidManifest：
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
我不知道我怎么能这样做。有人可以帮帮我吗？

看看这些代码行：
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);
我希望这会对你有所帮助。
