codenmaeone - 位置轮询始终返回相同的位置坐标

Question

我正在使用以下代码轮询设备的当前位置 位置loc = LocationManager.getLocationManager（）。getCurrentLocation（）;

每次返回相同的位置坐标。我必须使用getCurrentLocationSync（）吗？请告知可能出错的地方。

另外，我应该使用PRIORITY_HIGH_ACCUARCY或PRIORITY_MEDIUM_ACCUARCY而不是“PRIORITY_LOW_ACCUARCY”

代码：

public class TrackLocation implements LocationListener {

    private static TrackLocation instance = new TrackLocation();
    private Location lastLocation;
    private Timer time;

    public static TrackLocation getInstance() {
        return instance;
    }

    public void stopTracking() {
        if (time != null) {
            time.cancel();
        }
        time = null;
        LocationManager.getLocationManager().setLocationListener(null);
    }

    public void startTracking() {
        if (time != null) {
            stopTracking();
        }
        if (Preferences.get("LocationTracking", true)) {
            long delay = Server.instance.getLoctionPollingIntervalMillis();
            LocationManager.getLocationManager().setLocationListener(this,
                    new LocationRequest(LocationRequest.PRIORITY_LOW_ACCUARCY, delay));
            time = new Timer();
            time.schedule(new TimerTask() {
                @Override
                public void run() {
                    if (lastLocation != null) {
                        Server.instance.updateLocationInServer(lastLocation.getLatitude(), lastLocation.getLongitude(), System.currentTimeMillis(), true);
                    }
                }
            }, 30000, delay);
        }
    }

    @Override
    public void locationUpdated(Location location) {
        lastLocation = location;
    }

    @Override
    public void providerStateChanged(int newState) {
    }
}
