Как получить полный адрес из широты и долготы?

Я хочу получить следующие значения из широты и долготы в android

  • Адрес улицы
  • Город/штат
  • Zip
  • Полный адрес

Как это сделать?

Ответ 1

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

addresses = geocoder.getFromLocation(latitude, longitude, 1); // Here 1 represent max location result to returned, by documents it recommended 1 to 5

String address = addresses.get(0).getAddressLine(0); // If any additional address line present than only, check with max available address lines by getMaxAddressLineIndex()
String city = addresses.get(0).getLocality();
String state = addresses.get(0).getAdminArea();
String country = addresses.get(0).getCountryName();
String postalCode = addresses.get(0).getPostalCode();
String knownName = addresses.get(0).getFeatureName(); // Only if available else return NULL

Попробуйте этот мой друг

 private String getCompleteAddressString(double LATITUDE, double LONGITUDE) {
            String strAdd = "";
            Geocoder geocoder = new Geocoder(this, Locale.getDefault());
            try {
                List<Address> addresses = geocoder.getFromLocation(LATITUDE, LONGITUDE, 1);
                if (addresses != null) {
                    Address returnedAddress = addresses.get(0);
                    StringBuilder strReturnedAddress = new StringBuilder("");

                    for (int i = 0; i <= returnedAddress.getMaxAddressLineIndex(); i++) {
                        strReturnedAddress.append(returnedAddress.getAddressLine(i)).append("\n");
                    }
                    strAdd = strReturnedAddress.toString();
                    Log.w("My Current loction address", strReturnedAddress.toString());
                } else {
                    Log.w("My Current loction address", "No Address returned!");
                }
            } catch (Exception e) {
                e.printStackTrace();
                Log.w("My Current loction address", "Canont get Address!");
            }
            return strAdd;
        }

Последний способ получить адрес из Lat-Long (геокоординаты). Вы можете просто нажать веб-сервис google-maps, передавая широту и долготу. Это просто веб-сервис GET-Method.

Он вернет ответ JSON, который может быть легко проанализирован для получения адреса. URL для этого:

http://maps.googleapis.com/maps/api/geocode/json?latlng=32,75&sensor=true

Вы можете заменить 32,75 на lat, long.

Город и Страна не всегда попадают в адрес Строка 1 и Строка 2...

Пример здесь

Так,

Geocoder geocoder = new Geocoder(context, Locale.getDefault());

List<Address> addresses  = geocoder.getFromLocation(latitude,longitude, 1);
String address = addresses.get(0).getAddressLine(0);
String city = addresses.get(0).getLocality();
String state = addresses.get(0).getAdminArea();
String zip = addresses.get(0).getPostalCode();
String country = addresses.get(0).getCountryName();

В onCreate()..

LocationManager locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);
    locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 30000, 0, this);




    Criteria criteria = new Criteria();
    String bestProvider = locationManager.getBestProvider(criteria, true);
    Location location = locationManager.getLastKnownLocation(bestProvider);

    if (location == null) {
        Toast.makeText(getApplicationContext(), "GPS signal not found",
                3000).show();
    }
    if (location != null) {
        Log.e("locatin", "location--" + location);

        Log.e("latitude at beginning",
                "@@@@@@@@@@@@@@@" + location.getLatitude());
        onLocationChanged(location);
    }

Введите код в onLocationChanged()

@Override
public void onLocationChanged(Location location) {

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

    latitude = location.getLatitude();
    longitude = location.getLongitude();

    Log.e("latitude", "latitude--" + latitude);

    try {
        Log.e("latitude", "inside latitude--" + latitude);
        addresses = geocoder.getFromLocation(latitude, longitude, 1);





        if (addresses != null && addresses.size() > 0) {
            String address = addresses.get(0).getAddressLine(0); 
            String city = addresses.get(0).getLocality();
            String state = addresses.get(0).getAdminArea();
            String country = addresses.get(0).getCountryName();
            String postalCode = addresses.get(0).getPostalCode();
            String knownName = addresses.get(0).getFeatureName(); 

            locationTxt.setText(address + " " + city + " " + country);
        }
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}

Просто используйте этот метод и передайте свой lat, long.

public static void getAddress(Context context, double LATITUDE, double LONGITUDE) {

    //Set Address
    try {
        Geocoder geocoder = new Geocoder(context, Locale.getDefault());
        List<Address> addresses = geocoder.getFromLocation(LATITUDE, LONGITUDE, 1);
        if (addresses != null && addresses.size() > 0) {



            String address = addresses.get(0).getAddressLine(0); // If any additional address line present than only, check with max available address lines by getMaxAddressLineIndex()
            String city = addresses.get(0).getLocality();
            String state = addresses.get(0).getAdminArea();
            String country = addresses.get(0).getCountryName();
            String postalCode = addresses.get(0).getPostalCode();
            String knownName = addresses.get(0).getFeatureName(); // Only if available else return NULL

            Log.d(TAG, "getAddress:  address" + address);
            Log.d(TAG, "getAddress:  city" + city);
            Log.d(TAG, "getAddress:  state" + state);
            Log.d(TAG, "getAddress:  postalCode" + postalCode);
            Log.d(TAG, "getAddress:  knownName" + knownName);

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

Вы ищете термин "геокодирование".

Расскажите, что вам нужно сделать:

Geocoder geocoder = new Geocoder(this, Locale.getDefault());
List<Address> addresses = geocoder.getFromLocation(lat, lng, 1);

Чтобы сделать больше, вы должны прочитать здесь Geocoder здесь.

  public static String getAddressFromLatLng(Context context, LatLng latLng) {
    Geocoder geocoder;
    List<Address> addresses;
    geocoder = new Geocoder(context, Locale.getDefault());
    try {
        addresses = geocoder.getFromLocation(latLng.latitude, latLng.longitude, 1);
        return addresses.get(0).getAddressLine(0);
    } catch (Exception e) {
        e.printStackTrace();
        return "";

Его очень легко получить полный адрес по широте и долготе с использованием класса Geocoder. Следуя образцу кода. Надеюсь это поможет!

 if (l != null) {
        val lat = l.latitude
        val lon = l.longitude

        val geocoder = Geocoder(this, Locale.getDefault())
        val addresses: List<Address>

        addresses = geocoder.getFromLocation(lat, lon, 1) 

        val address = addresses[0].getAddressLine(0)
        val address2 = addresses[0].getAddressLine(1)
        val city = addresses[0].locality
        val state = addresses[0].adminArea
        val country = addresses[0].countryName
        val postalCode = addresses[0].postalCode
        val knownName = addresses[0].featureName

        val message =
                "Emergency situation. Call for help. My location is: " + address + "." + "http://maps.google.com/maps?saddr=" + lat + "," + lon

    }

Вы можете использовать только значение адреса, поскольку оно дает вам полный адрес. Если вам нужны отдельные компоненты, вы можете использовать и другие.

                mPostalCode = addressFields[4];
                mCity = addressFields[5];
                break;
            default:
                mLatitude = null;
                mLongtitude = null;
                mStreet = null;
                mHouseNumber = null;
                mPostalCode = null;
                mCity = null;
                break;
        }

        Log.d("GeoLocation Street", mStreet);
        Log.d("GeoLocation No.", mHouseNumber);
        Log.d("GeoLocation Postalcode", mPostalCode);
        Log.d("GeoLocation Locality", mCity);
        Log.d("GeoLocation Lat/Lng", "[" + mLatitude + ", " + mLongtitude + 
    "]");
    }
 }
   }

Затем вы создаете экземпляр, используя

GeoLocation geoLocation = new GeoLocation(getActivity()); // or (this) if 
called from an activity and not from a fragment
mGeoLocation.lookUpAddress(LOCATION_FROM_MAP);

Используйте это, это работает для меня: D

Получить JSON данные широты и долготы.

https://maps.googleapis.com/maps/api/geocode/json?key=AIzaSyAr29XeWWAeWZcrOgjjfs3iSnqkWtAz4No&latlng=2.1812,102.4266&sensor=true

Измените широту, долготу с вашим собственным местом.

https://maps.googleapis.com/maps/api/geocode/json?key= <\ API_KEY_HERE> & latlng = "широта", "долгота" & sensor = true

Вы можете изменить <\ API_KEY_HERE> своим собственным ключом.

Необходимо включить службу API в консоли Google для нового ключа API.

Попробуйте использовать код ниже с помощью геокодера:

  Geocoder gcd = new Geocoder(MainActivity.this, Locale.getDefault());
  List<Address> geoAddresses = geoAddresses = gcd.getFromLocation(location.getLatitude(), location.getLongitude(), 1);
  if (geoAddresses.size() > 0) {
      String mUserLocation = "";
      for (int i = 0; i < 4; i++) { //Since it return only four value we declare this as static.
           mUserLocation = mUserLocation + geoAddresses.get(0).getAddressLine(i).replace(",", "") + ", ";
        } 
    }

Ответ 19

1 - Вы создаете переменные для LocationManager и LocationListener в методе onCreate.

2 - Проверьте, есть ли разрешение, чтобы выполнить обновление местоположения и получить lastKnownLocation из locationManager, иначе вы запрашиваете разрешение

3 - Создайте onRequestPermissionResult в основном классе и проверьте, есть ли разрешение, затем выполните обновления местоположения

4 - Создайте разделенный метод, который включает переменную Geocoder и создайте список, чтобы поместить координаты из вашего местоположения, поэтому, чтобы быть в безопасности, вы проверяете, существует ли Список, и если каждая информация, которую мы хотим в этом списке, существует, тогда вы используете (getThoroughfare = => для уличного адреса), (getLocality ==> для города/состояния), (getPostalCode ==> для Zip), (getAdminArea ==> для полного адреса)

5 - Наконец, вы вызываете этот метод после проверки разрешения с помощью параметра lastKnownLocation ==> для отображения адреса при запуске приложения) и в onLocationChanged (параметр location ==> для отображения адреса при изменении местоположения)

Кажется, что никто еще не предоставил решение, предлагаемое Google Docs (https://developer.android.com/training/location/display-address#java). Правильное решение должно использовать IntentService для создания сетевого вызова для обратного геокодирования.

Используется служба намерений, а не AsyncTask, поскольку она не привязана к какой-либо конкретной деятельности. то есть. он имеет собственный жизненный цикл. IntentService остановится, когда закончится геокодирование.

public class GeocodingService extends IntentService {

    public GeocodingService() {
        super("GeocodingService");
    }


    @Override
    protected void onHandleIntent(@Nullable Intent intent) {

        BCCDatabase BCCDatabase = skicompanion.skicompanion.storage.BCCDatabase.getInstance(getApplicationContext());

        // Get the location passed to this service through an extra.
        Location location = intent.getParcelableExtra(
                "location");
        long trackID = intent.getLongExtra("trackID", -1);
