如何从android devide获取经度和纬度？

Question

我有一个应用程序已经在请求运行时权限来激活本地化权限，我已经准备好接收经度和纬度。我现在的问题只是从设备本身获取纬度和经度。

这是我的方法，请假定该方法转到else语句，因为我已经具有处理权限的权限

 if (!checkPermissions()) {
        requestPermissions()
    } else {

        //get latitude and long here
    }

Answer 1

这是示例代码

1.LocationManager和侦听器

private LocationManager locationManager;
private LocationListener locationListener;

2。设置管理器和监听器

locationManager = (LocationManager)this.getSystemService(Context.LOCATION_SERVICE);

locationListener = new LocationListener() {
    public void onLocationChanged(Location location) {
        double latitude = location.getLatitude();
        double longitude = location.getLongitude();
    }
}

locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, locationListener);
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, locationListener);
    String locationProvider = LocationManager.GPS_PROVIDER;
    currentLocation = locationManager.getLastKnownLocation(locationProvider);
    if (currentLocation != null) {
        double lng = currentLocation.getLongitude();
        double lat = currentLocation.getLatitude();
        Log.d("Log", "longtitude=" + lng + ", latitude=" + lat);
    }
