为什么，onlocationchanged no 它在使用数据移动时被调用？

Question

当我使用 gps 或 wifi 时 onlocationchanged 工作正常，但是当我使用数据移动时，onlocationchanged 它只被调用一次并且位置提供它很糟糕。

我希望你能帮助我，我真的需要用数据移动获取位置。

这是我的代码：

public class ObtenerLatLng implements LocationListener {

    public static double latitude = 0.0;
    public static double longitude = 0.0;
    public static boolean flaglocation=true;
    int contador;
    Context context;
    LocationManager locationManager;


    public ObtenerLatLng(Context context) {
        this.context = context;
        obtenerlatlng(context);
    }

    public void obtenerlatlng(Context context) {


        Log.i("hola ", "Se HA SOLICITADO LOCALIZACION");
        NetworkInfo aux;
        NetworkInfo isWifiOn = null;
        NetworkInfo isMobiledataOn = null;



        ConnectivityManager cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
            Network[] todas = cm.getAllNetworks();

            for (Network item : todas) {
                aux = cm.getNetworkInfo(item);
                if (aux.getType() == ConnectivityManager.TYPE_WIFI) {
                    isWifiOn = aux;
                }
                if (aux.getType() == ConnectivityManager.TYPE_MOBILE) {
                    isMobiledataOn = aux;
                }
            }

        } else {
            isWifiOn = cm.getNetworkInfo(ConnectivityManager.TYPE_WIFI);
            isMobiledataOn = cm.getNetworkInfo(ConnectivityManager.TYPE_MOBILE);

        }


        locationManager = (LocationManager) context.getSystemService(Context.LOCATION_SERVICE);
        if (locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER)) {

            if (isMobiledataOn.isConnected() || isWifiOn.isConnected() ) {
                Toast.makeText(context, "entre a Network", Toast.LENGTH_LONG).show();
                if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
                    if (context.checkSelfPermission(Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && context.checkSelfPermission(Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
                        locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 10000, 1, this);


                    }
                } else {
                    locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 10000, 1, this);

                }
            } else if (locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER)) {
                Toast.makeText(context, "entre a gps", Toast.LENGTH_LONG).show();
                if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
                    if (context.checkSelfPermission(Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && context.checkSelfPermission(Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {

                        locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 10000, 1, this);

                    }
                } else {

                    locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 10000, 1, this);

                }

            }

        } else {
            flaglocation=false;
           // Toast.makeText(context, "Revise la configuracion de red", Toast.LENGTH_LONG).show();

        }

    }


    @Override
    public void onLocationChanged(Location location) {

        if (location!= null ) {
            flaglocation=true;
            Toast.makeText(context, "Se actualizo la localizacion " + location.getLatitude() + "  " + location.getLongitude(), Toast.LENGTH_LONG).show();
            latitude = location.getLatitude();
            longitude = location.getLongitude();

        }

    }



    }

}

使用移动数据，您只能获得手机位置。请参阅 this 了解如何接收小区位置。

Network_provider 至少需要 WiFi 才能接收网络或粗略的位置。

为什么，onlocationchanged no 它在使用数据移动时被调用？
