Kotlin

Question

我正在从 NETWORK_PROVIDER 获取位置，如下所示：

if(manager.isProviderEnabled(LocationManager.NETWORK_PROVIDER))
            {
                val locationManager = mContext.getSystemService(Context.LOCATION_SERVICE) as LocationManager

                // Define a listener that responds to location updates
                val locationListener = object : LocationListener {

                    override fun onLocationChanged(location: Location) {
                        // Called when a new location is found by the network location provider.
                        if (location != null) {
                            lastLocation = location
                            currentLatLng = LatLng(location.latitude, location.longitude)


                            if (currentLatLng != null &&
                                currentLatLng.latitude != null &&
                                currentLatLng.longitude != null
                            ) {

                                sharedPreferenceManager?.setStringData(
                                    Constant.PrefKey.userLatitude,
                                    "" + currentLatLng.latitude
                                )

                                sharedPreferenceManager?.setStringData(
                                    Constant.PrefKey.userLongitude,
                                    "" + currentLatLng.longitude
                                )

                                getAddress(currentLatLng)
                            }
                        }else{
                            ToastUtil.displayLongDurationToast(mContext,"Could not get Location. Please turn on GPS and try again.")
                            getAndSaveCurrentLocation()
                        }
                    }
                }
                // Register the listener with the Location Manager to receive location updates
                locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0L, 0f,locationListener)

但是，在方法 requestLocationUpdates 的最后一行出现错误：

None of the following function can be called with the arguments supplied

可能是什么问题？我已经传递了有效参数。

编辑：在此行获取参数错误：

locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0L, 0f,locationListener)

Answer 1

很可能您导入了错误的 LocationListener。您可能正在使用 com.google.android.gms.location.LocationListener

但是你需要导入android.location.LocationListener

检查您的导入并更改导入以更正 LocationListener 并且调用应该有效。
