我想用我在谷歌地圖上的位置的android

Question

MarkerOptions markerOptions = new MarkerOptions().position(position) 
      .draggable(true); 
@Override 
public boolean onMarkerClick(Marker marker) { 
    // TODO Auto-generated method stub 
    Log.i("GoogleMapActivity", "onMarkerClick"); 
    Toast.makeText(getApplicationContext(), 
      "Marker Clicked: " + marker.getTitle(), Toast.LENGTH_LONG) 
      .show(); 
    return false; 
} 

@Override 
public void onMarkerDrag(Marker arg0) { 
    // TODO Auto-generated method stub 

} 

@Override 
public void onMarkerDragEnd(Marker marker) { 
    // TODO Auto-generated method stub 
    double lat = marker.getPosition().latitude; 
    double lng = marker.getPosition().longitude; 
    Toast.makeText(
      getApplicationContext(), 
      "Marker " + marker.getTitle() + " dragged from " + fromPosition 
        + " to " + lat + lng, Toast.LENGTH_LONG).show(); 
} 

@Override 
public void onMarkerDragStart(Marker marker) { 
    // TODO Auto-generated method stub 
    fromPosition = marker.getPosition(); 
    Log.e(getClass().getSimpleName(), "Drag start at: " + fromPosition); 

} 

在此代碼的工作完成了，但我想設置引腳圖中心和拖動地圖，然後設置lat和長

Answer 1

試試這個代碼來設置。

map = mapView.getMap(); 
    markerOptions = new MarkerOptions(); 
    MapsInitializer.initialize(this.getActivity()); 
    appLocationService = new AppLocationService(getActivity()); 
    nwLocation = appLocationService.getLocation(LocationManager.NETWORK_PROVIDER); 
    if (nwLocation != null) { 
     userlatitude = nwLocation.getLatitude(); 
     userlongitude = nwLocation.getLongitude(); 
     MarkerOptions userlocmarker = new MarkerOptions(); 
     userlocmarker.position(new LatLng(userlatitude, userlongitude)); 
     userlocmarker.icon(BitmapDescriptorFactory.fromResource(R.drawable.usermarker)); 
     userlocmarker.title("You are here!"); 
     userlocmarker.snippet(""); 
     map.addMarker(userlocmarker); 
     MapsInitializer.initialize(this.getActivity()); 
     CameraUpdate cameraUpdate = CameraUpdateFactory.newLatLngZoom(new LatLng(userlatitude, userlongitude), 11); 
     map.animateCamera(cameraUpdate); 
    }
