android - 如何从地点选择器的地址获取国家，城市？

Question

我正在使用地点选择器的 Intent 来获取地点。现在我想将地址以国家、城市、密码、州的形式保存。我怎样才能从地点选择器的地址得到所有这些？

代码:

public class NameOfBusinessFragment extends Fragment {

    int PLACE_PICKER_REQUEST = 1;
    int RESULT_OK = -1;
    PlacePicker.IntentBuilder builder = new PlacePicker.IntentBuilder();
    EditText category,location;

        @Override
        public View onCreateView(LayoutInflater inflater, ViewGroup container,
                                 Bundle savedInstanceState) {
            View view = inflater.inflate(R.layout.fragment_name_of_business,
                    container, false);

            location = (EditText)view.findViewById(R.id.location);

            location.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {

                    try {

                        startActivityForResult(builder.build(getActivity()), PLACE_PICKER_REQUEST);
                    }
                    catch (GooglePlayServicesRepairableException e)
                    {
                        Toast.makeText(getActivity(),"ServiceRepaire Exception",Toast.LENGTH_SHORT).show();
                    }
                    catch (GooglePlayServicesNotAvailableException  e)
                    {
                        Toast.makeText(getActivity(),"SeerviceNotAvailable Exception",Toast.LENGTH_SHORT).show();
                    }
                }
            });

            return view;
        }
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (requestCode == PLACE_PICKER_REQUEST) {
            if (resultCode == RESULT_OK) {
                Place place = PlacePicker.getPlace(data, getActivity());
                String toastMsg = String.format("Place: %s", place.getName());


                Toast.makeText(getActivity(), toastMsg, Toast.LENGTH_LONG).show();
                location.setText(place.getName());
            }
        }
    }
}

这就是我实现地点选择器并在 ActivityResult 上获取地点名称的方式。我可以使用反向地理编码或其他方式获得它吗？谁能帮我解决这个问题？谢谢。

我认为直接使用 Place 类是不可能的，但你可以要求它从纬度和经度开始谷歌。下面是您的 onActivityResult 方法的示例:

public void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == PLACE_PICKER_REQUEST) {
        if (resultCode == RESULT_OK) {
            // get place data
            Place place = PlacePicker.getPlace(data, getActivity());

            // ask for geolocation data
            Geocoder gcd = new Geocoder(this, Locale.getDefault());
            List<Address> addresses = null;
            try {
                addresses = gcd.getFromLocation(place.getLatLng().latitude, place.getLatLng().longitude, 1);
            } catch (IOException e) {
                e.printStackTrace();
            }
            if (addresses.size() > 0) {
                String toastMsg = String.format("Place: %s", addresses.get(0).getLocality() + " - " + addresses.get(0).getCountryName() + " - " + addresses.get(0).getCountryCode());
                Toast.makeText(getActivity(), toastMsg, Toast.LENGTH_LONG).show();


                // NOW SET HERE CORRECT DATA
                //location.setText(place.getName());

            }
        }
    }
}
