java - 将位置数据从 fragment 传递到 Android 中的 Activity

Question

当用户长时间点击 mapFragment 时，我想将有关点击位置的数据发送到另一个 Activity ，即。我想将纬度、经度、城市、邮政编码、国家...传递给 LocationDetailsActivity。

我成功地通过了纬度和经度测试，但我遇到了其他所有问题。我是编码和 Android 的初学者，所以我使用分步示例，到目前为止我找不到任何分步示例。

代码:

    if (myLocation != null) {
        latitude = myLocation.getLatitude();
        longitude = myLocation.getLongitude();
    }

    mMap.setOnMapLongClickListener(new GoogleMap.OnMapLongClickListener() {

        @Override
        public void onMapLongClick(LatLng arg0) {

            Geocoder geocoder = new Geocoder(getActivity(), Locale.getDefault());
            try {
                List<Address> allAddresses = geocoder.getFromLocation(arg0.latitude, arg0.longitude, 1);
                  if (allAddresses.size() > 0) {
                    Address address = allAddresses.get(0);
                      String addressline = allAddresses.get(0).getAddressLine(0);
                      String city = allAddresses.get(0).getLocality();
                      String state = allAddresses.get(0).getAdminArea();
                      String country = allAddresses.get(0).getCountryName();
                      String postalCode = allAddresses.get(0).getPostalCode();
                }

            } catch (IOException e) {
                e.printStackTrace();
            }


            Intent intent = new Intent(getActivity(), LocationDetailsActivity.class);
            intent.putExtra("latitude", arg0.latitude);
            intent.putExtra("longitude", arg0.longitude);
            intent.putExtra("city",);
            intent.putExtra("zip",);
            intent.putExtra("country",);
            startActivity(intent);

        }
    });

感谢任何帮助:)

试试这个:

mMap.setOnMapLongClickListener(new GoogleMap.OnMapLongClickListener() {

        @Override
        public void onMapLongClick(LatLng arg0) {

            Geocoder geocoder = new Geocoder(getActivity(), Locale.getDefault());
            try {
                List<Address> allAddresses = geocoder.getFromLocation(arg0.latitude, arg0.longitude, 1);
                  if (allAddresses.size() > 0) {
                    Address address = allAddresses.get(0);

                     Intent intent = new Intent(getActivity(), LocationDetailsActivity.class);
                     intent.putExtra("latitude", arg0.latitude);
                     intent.putExtra("longitude", arg0.longitude);
                     intent.putExtra("city", allAddresses.get(0).getLocality());
                     intent.putExtra("zip", allAddresses.get(0).getPostalCode());
                     intent.putExtra("state", allAddresses.get(0).getAdminArea());
                     intent.putExtra("country", allAddresses.get(0).getCountryName());
                     startActivity(intent);
                }

            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    });
