Je veux obtenir les valeurs suivantes de Latitude et Longitude dans Android
Comment y parvenir?
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

Il existe un dernier truc pour obtenir l'adresse de Lat-Long (coordonnées géographiques). Vous pouvez simplement cliquer sur le service Web Google Maps en passant la latitude et la longitude. C'est simplement un service Web GET-Method.
Il retournera la réponse JSON qui peut être analysée facilement pour obtenir une adresse. L'URL pour cela est:
http://maps.googleapis.com/maps/api/geocode/json?latlng=32,75&sensor=true
Vous pouvez remplacer 32,75 par lat, long .
Ville & Pays n'entrent pas toujours dans les lignes 1 et 2 ...
Exemple: ici
Alors,
Geocoder geocoder = new Geocoder(context, Locale.getDefault());
List<Address> addresses = geocoder.getFromLocation(latitude,longitude, 1);
String city = addresses.get(0).getLocality();
String state = addresses.get(0).getAdminArea();
String Zip = addresses.get(0).getPostalCode();
String country = addresses.get(0).getCountryName();
Dans 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);
}
Écrivez le code dans 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();
}
}
Utilisez simplement cette méthode et passez votre 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()

Vous recherchez le terme géocodage.
La nouvelle est que vous devez faire:
Geocoder geocoder = new Geocoder(this, Locale.getDefault());
List<Address> addresses = geocoder.getFromLocation(lat, lng, 1);
Pour faire plus, vous devriez lire sur le géocodeur ici .
Vous pouvez faire comme ceci pour obtenir une adresse complète à partir de la latitude et de la longitude:
public class MainActivity extends AppCompatActivity {
...
private Geocoder geocoder;
private TextView mAddressTxtVu;
...
// I assume that you got latitude and longitude correctly
mLatitude = 20.23232
mLongitude = 32.999
String errorMessage = "";
geocoder = new Geocoder(context, Locale.getDefault());
List<Address> addresses = null;
try {
addresses = geocoder.getFromLocation(
mlattitude,
mlongitude,
1);
} catch (IOException e) {
errorMessage = getString(R.string.service_not_available);
Log.e(TAG, errorMessage, e);
} catch (IllegalArgumentException illegalArgumentException) {
// Catch invalid latitude or longitude values.
errorMessage = getString(R.string.invalid_lat_long_used);
Log.e(TAG, errorMessage + ". " + "Latitude = " + mlattitude +", Longitude = " + mlongitude, illegalArgumentException);
}
// 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);
}
} 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));
}
// Log.i(TAG, getString(R.string.address_found));
mAddressTxtVu.setText(TextUtils.join(System.getProperty("line.separator"),
addressFragments));
}
Il est très facile d'obtenir une adresse complète à partir de la latitude et de la longitude à l'aide de la classe Geocoder. Suite à l'exemple de code. J'espère que cela t'aides!
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
}
Vous ne pouvez utiliser que la valeur d'adresse car elle vous donne l'adresse complète. Si vous voulez des composants individuels, vous pouvez également utiliser d'autres composants.
Vous pouvez créer une classe
public class GeoLocation {
private Context mContext;
private String mLatitude;
private String mLongtitude;
private String mStreet;

// Format address string after lookup
@Override

// Workaround: doInBackground can only return Strings instead of, for example, an

// on fields returned by this method, set each String that currently reads "null" to
// a null reference
for (int fieldcnt = 0; fieldcnt < addressFields.length; ++fieldcnt) {
if (addressFields[fieldcnt].equals("null"))
addressFields[fieldcnt] = null;
}
switch (addressFields.length) {
case 4:
mStreet = null;
mHouseNumber = null;
mLatitude = addressFields[0];
mLongtitude = addressFields[1];
mPostalCode = addressFields[2];
mCity = addressFields[3];
break;
case 6:
mLatitude = addressFields[0];
mLongtitude = addressFields[1];
mStreet = addressFields[2];
mHouseNumber = addressFields[3];
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 +
"]");
}
}
}
Vous l'instanciez alors en utilisant
GeoLocation geoLocation = new GeoLocation(getActivity()); // or (this) if
called from an activity and not from a fragment
mGeoLocation.lookUpAddress(LOCATION_FROM_MAP);
Vous pouvez facilement utiliser le code suivant pour obtenir l'adresse.

Utilise ça ça marche pour moi: D
Récupère les données JSON de la latitude et de la longitude.
Changer la latitude, la longitude avec votre propre lieu.
https://maps.googleapis.com/maps/api/geocode/json?key= <\ API_KEY_HERE> & latlng = "latitude", "longitude" & sensor = true
Vous pouvez changer le <\ API_KEY_HERE> avec votre propre clé.
Besoin d'activer le service api dans la console Google pour la nouvelle clé api.
J'espère que ça aide: D
1 - Vous créez des variables pour LocationManager et LocationListener dans la méthode onCreate.
2 - Vérifiez s'il y a une permission alors exécutez les mises à jour d'emplacement et obtenez lastKnownLocation de locationManager, sinon vous demandez la permission
3 - Créez onRequestPermissionResult dans la classe principale et vérifiez s’il existe une autorisation, puis exécutez les mises à jour d’emplacement.
4 - Créez une méthode séparée qui inclut la variable Geocoder et créez une liste pour mettre les coordonnées de votre position, Pour être sûr, vérifiez si la liste existe et si chaque information que nous souhaitons dans cette liste existe, vous utilisez (getThoroughfare ==> pour l'adresse), (getLocality ==> pour la ville/l'État), (getPostalCode ==> pour le code postal), (getAdminArea ==> pour l'adresse complète)
5 - Enfin, vous appelez cette méthode après avoir vérifié l'autorisation avec (paramètre lastKnownLocation ==> pour afficher l'adresse lorsque l'application est exécutée) et dans onLocationChanged avec (paramètre d'emplacement ==> pour afficher l'adresse lorsque l'emplacement change).

Il semble que personne n'ait encore fourni la solution proposée par Google Documents ( https://developer.Android.com/training/location/display-address#Java ). La solution appropriée doit utiliser IntentService pour effectuer l'appel réseau pour le géocodage inversé.
Un service d'intention est utilisé plutôt qu'une AsyncTask car il n'est lié à aucune activité spécifique. c'est à dire. il a son propre cycle de vie. IntentService s’arrêtera une fois le géocodage terminé.
