我如何才能将直接从 Google 地点 API 获得的地址组件明智地分叉？

Question

我想将城市、州、国家/地区固定到不同的变量中，就像我获取地址、纬度和经度一样。但我不知道如何获取地址组件。

public class MainActivity extends AppCompatActivity {
String TAG = "placeautocomplete";
String API = "xxxxxxxxxxxxxxxxx";
String Latitude;
String Longitude;
double lat, lng;
String Address,Place_name,Phone,Complete_address;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    edit = findViewById(R.id.editText);
    txtView = findViewById(R.id.txtView);
    // Initialize Places.
    Places.initialize(getApplicationContext(), API);
    // Create a new Places client instance.
    PlacesClient placesClient = Places.createClient(this);

    // Initialize the AutocompleteSupportFragment.
    if (!Places.isInitialized()) {
        Places.initialize(getApplicationContext(), API);


    }

    // Initialize the AutocompleteSupportFragment.
    AutocompleteSupportFragment autocompleteFragment = (AutocompleteSupportFragment)
            getSupportFragmentManager().findFragmentById(R.id.autocomplete_fragment);

    assert autocompleteFragment != null;

    autocompleteFragment.setPlaceFields(Arrays.asList(Place.Field.ID, Place.Field.NAME,Place.Field.LAT_LNG, Place.Field.ADDRESS,Place.Field.PHONE_NUMBER));
    autocompleteFragment.setOnPlaceSelectedListener(new PlaceSelectionListener() {
        @Override
        public void onPlaceSelected(Place place) {
            // TODO: Get info about the selected place.
            Log.i(TAG, "Place: " + place.getName() + ", " + place.getId());

            if (place.getLatLng() !=null){
                lat =place.getLatLng().latitude;
                lng =place.getLatLng().longitude;

            }
            Latitude = String.valueOf(lat);
            Longitude= String.valueOf(lng);
            Address= place.getAddress();
            Place_name = place.getName();
            Phone = place.getPhoneNumber();

        }
        @Override
        public void onError(Status status) {
            // TODO: Handle the error.
            Log.i(TAG, "An error occurred: " + status);
        }
    });
}
 }

我只想在 Address、City、State、Pin 等组件中添加地址。

你不应该使用 Address= place.getAddress() 而应该使用 .getAddressComponents()，因为 .getAddress() returns String 具有人类可读的地点地址和官方文档 Google 写道：

Do not parse the formatted address programmatically. Instead you should use the individual address components, which the API response includes in addition to the formatted address field.

所以，你应该使用Place.getAddressComponents() to get List<AddressComponent> and than get name and type of each address component. Or use additional request for place lat/lng and Geocoder.getFromLocation() like in Display a location address官方例子：

...
Geocoder geocoder = new Geocoder(this, Locale.getDefault());
List<Address> addresses = null;

...
addresses = geocoder.getFromLocation(
            Latitude,    // <-- your Latitude = String.valueOf(lat);
            Longitude,   // <- your Longitude= String.valueOf(lng);
            location.getLongitude(),
            // In this sample, get just a single address.
            1);

// Handle case where no address was found.
if (addresses == null || addresses.size()  == 0) {
    if (errorMessage.isEmpty()) {
        errorMessage = getString(R.string.no_address_found);
        Log.e(TAG, errorMessage);
    }
    deliverResultToReceiver(Constants.FAILURE_RESULT, errorMessage);
} else {
    Address address = addresses.get(0);
    ArrayList<String> addressFragments = new ArrayList<String>();

    // Fetch the address lines using getAddressLine,
    // join them, and send them to the thread.
    for(int i = 0; i <= address.getMaxAddressLineIndex(); i++) {
        addressFragments.add(address.getAddressLine(i));
    }
}
...

也看看Developer Guide。

P.S。不要对变量使用大写名称（例如，Latitude）——这是类的风格。将其命名为 latitude.

How can I bifurcated address component wise which I am getting directly from Google Place API?
