从当前位置和所选位置获取纬度和经度值

Question

我在地图中创建了当前位置。还有一个Spinner视图来选择目标位置。在我的情况下，我想从当前位置和选定位置获取纬度和经度。我想在onInfoWindowClick()方法中执行这些值。 有人能帮我吗？ 这是我的代码

public void onMapReady(GoogleMap googleMap) {
        mMap = googleMap;

        if (mLocationPermissionGranted){
            getDeviceLocation();

            if (ActivityCompat.checkSelfPermission(getActivity(), Manifest.permission.ACCESS_FINE_LOCATION)
                    != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(getActivity(),
                    Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {

                return;
            }
            mMap.setMyLocationEnabled(true);
        }

        SQLiteDatabase db = dbHelper.getReadableDatabase();
        cursor = db.rawQuery("SELECT * FROM atm", null);

        if (cursor != null){
            while (cursor.moveToNext()){
                title = cursor.getString(1).toString();
                __global_endposition = cursor.getString(2).toString();
                String[] exp_endCoordinate = __global_endposition.split(",");
                final double lat_endposition = Double.parseDouble(exp_endCoordinate[0]);
                double lng_endposition = Double.parseDouble(exp_endCoordinate[1]);
                LatLng endx = new LatLng(lat_endposition, lng_endposition);

                MarkerOptions options = new MarkerOptions();
                options.position(endx);
                options.title(title);
                options.snippet(__global_endposition);
                if (title.equals("ATM BNI")){
                    options.icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_ORANGE));
                }else if(title.equals("ATM BCA")){
                    options.icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_BLUE));
                }else if(title.equals("ATM Mandiri")){
                    options.icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_YELLOW));
                }

                Marker marker = mMap.addMarker(options);

                mMap.setInfoWindowAdapter(new CustomInfoWindowAdapter(getActivity()));

                mMap.setOnInfoWindowClickListener(new GoogleMap.OnInfoWindowClickListener() {
                    @Override
                    public void onInfoWindowClick(Marker marker) {
                        // Take LatLong current Location and LatLong selected location
                    }
                });
            }

            if (!cursor.isClosed()) {
                cursor.close();
                cursor = null;
            }

        }

        mMap.getUiSettings().setZoomControlsEnabled(true);

    }

这是我的getDeviceLocation()代码：

private void getDeviceLocation(){
        Log.d(TAG, "geDeviceLocation: mendapatkan lokasi pengguna");

        mFusedLocationProviderClient = LocationServices.getFusedLocationProviderClient(getActivity());

        try {
            if (mLocationPermissionGranted){
                Task location = mFusedLocationProviderClient.getLastLocation();
                location.addOnCompleteListener(new OnCompleteListener() {
                    @Override
                    public void onComplete(@NonNull Task task) {
                        if (task.isSuccessful()){
                            Log.d(TAG, "onComplete: lokasi ditemukan");
                            Location currentLocation = (Location) task.getResult();

                            // public variable
                            mLatitude = currentLocation.getLatitude();
                            mLongitude = currentLocation.getLongitude();

                            if (currentLocation != null){
                                moveCamera(new LatLng(mLatitude, mLongitude),
                                        DEFAULT_ZOOM);
                            }

                        }else{
                            Log.d(TAG, "onComplete: lokasi tidak ditemukan");
                            Toast.makeText(getActivity(), "Lokasi tidak ditemukan", Toast.LENGTH_SHORT).show();
                        }
                    }
                });
            }
        }catch (SecurityException e){
            Log.e(TAG, "geDeviceLocation: SecurityException"+e.getMessage() );
        }
    }
