Question

我是HERE地图的新手，目前正试图从定位管理器，getlocation（）方法获取当前用户位置，但我的代码始终返回以下信息

com.nokia.maps.GeoPositionImpl [坐标=会有地理座标[纬度= -179769313486232000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000.000000经度= -179769313486232000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000.000000海拔= 1073741824.000000有效值= FALSE]]

以下是我的代码：

     protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
            //requestPermissions();

            // Search for the Map Fragment
            final MapFragment mapFragment = (MapFragment)
                    getFragmentManager().findFragmentById(R.id.mapfragment);
    // initialize the Map Fragment and
    // retrieve the map that is associated to the fragment
            mapFragment.init(new OnEngineInitListener() {
                @Override
                public void onEngineInitializationCompleted(
                        OnEngineInitListener.Error error) {
                    if (error == OnEngineInitListener.Error.NONE) {
    // now the map is ready to be used
                        map = mapFragment.getMap();

                        onMapFragmentInitializationCompleted();
      } else {
                        System.out.println("ERROR: Cannot initialize MapFragment");
                        System.out.println("ERROR: Cannot initialize Map Fragment: " + error.toString());
                    }
                }
            });

       }




     private void onMapFragmentInitializationCompleted() {
            PositioningManager posManager;
             MapContainer placesContainer = null;
            // retrieve a reference of the map from the map fragment
           // map = mapFragment.getMap();
            // start the position manager
            posManager = PositioningManager.getInstance();
            posManager.start(PositioningManager.LocationMethod.GPS_NETWORK);

            GeoPosition position = posManager.getPosition();
            GeoCoordinate cor = position.getCoordinate();

            // Set a pedestrian friendly map scheme
            map.setMapScheme(Map.Scheme.PEDESTRIAN_DAY);

            // Display position indicator
            map.getPositionIndicator().setVisible(true);

            placesContainer = new MapContainer();
            map.addMapObject(placesContainer);

            // Set the map center coordinate to the current position
            map.setCenter(posManager.getPosition().getCoordinate(), Map.Animation.NONE);
            map.setZoomLevel(14);
        }

有效= FALSE表示您的设备没有GPS锁定。您的设备是否在室内且无法获得位置？其次，请检查您的申请是否具有定位权限。

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION " />

Android：HERE地图定位管理器getposition（）总是返回Lat：17976931348623200 ..，Lon：17976931348623200
