我想让用户的当前位置(经度和纬度)始终只使用基于Sim的网络,而不是使用任何其他网络(如WiFi,移动数据,GPS和其他网络,甚至所有这些都在移动设备中处于禁用模式).不一定是确切的位置,但甚至大致的位置

有没有可能得到它？如果您有任何人可以解释并包含代码;我在谷歌搜索但没有得到正确的相关答案.

            _addressText = FindViewById<TextView>(Resource.Id.address_text);
            _locationText = FindViewById<TextView>(Resource.Id.location_text);

            FindViewById<TextView>(Resource.Id.get_address_button).Click += AddressButton_OnClick;
            InitializeLocationManager();


        }

            Criteria criteriaForLocationService = new Criteria

                Accuracy = Accuracy.Fine
            };

            }
        }


        protected override void OnResume()
        {
            base.OnResume();
            _locationManager.RequestLocationUpdates(_locationProvider, 0, 0, this);
        }


        protected override void OnPause()
        {
            base.OnPause();
            _locationManager.RemoveUpdates(this);
        }

        async void AddressButton_OnClick(object sender, EventArgs eventArgs)
        {
            if (_currentLocation == null)
            {
                _addressText.Text = "Can't determine the current location.";
                return;
            }

            Geocoder geocoder = new Geocoder(this);
            IList<Address> addressList = await geocoder.GetFromLocationAsync(_currentLocation.Latitude, _currentLocation.Longitude, 10);

            Address address = addressList.FirstOrDefault();
            if (address != null)
            {
                StringBuilder deviceAddress = new StringBuilder();
                for (int i = 0; i < address.MaxAddressLineIndex; i++)
                {
                    deviceAddress.Append(address.GetAddressLine(i))
                        .AppendLine(",");
                }
                _addressText.Text = deviceAddress.ToString();
            }
            else
            {
                _addressText.Text = "Unable to determine the address.";
            }

     }  

        public void OnLocationChanged(Location location)
        {
            _currentLocation = location;
            if (_currentLocation == null)
            {
                _locationText.Text = "Unable to determine your location.";
            }
            else
            {
                _locationText.Text = String.Format("{0},{1}", _currentLocation.Latitude, _currentLocation.Longitude);
            }

        }

        public void OnProviderDisabled(string provider) { }

        public void OnProviderEnabled(string provider) { }

        public void OnStatusChanged(string provider, Availability status, Bundle extras) { }
    }
}

解决方法:

您可以使用LocationManager.NETWORK_PROVIDER获取纬度和经度而无需打开GPS

    btnNWShowLocation.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View arg0) {

            Location nwLocation = appLocationService
                    .getLocation(LocationManager.NETWORK_PROVIDER);

            if (nwLocation != null) {
                double latitude = nwLocation.getLatitude();
                double longitude = nwLocation.getLongitude();
                Toast.makeText(
                        getApplicationContext(),
                        "Mobile Location (NW): \nLatitude: " + latitude
                                + "\nLongitude: " + longitude,
                        Toast.LENGTH_LONG).show();

            } else {
                showSettingsAlert("NETWORK");
            }

        }
    });
