Comment obtenir le nom de la ville à partir des coordonnées de latitude et de longitude dans Google Maps?
Comment puis-je obtenir le nom de la ville dans Google Maps si j'ai la latitude et la longitude d'une ville ou d'une région?
j'ai essayé d'utiliser la latitude, la longitude et j'ai obtenu le pays mais je ne sais pas comment obtenir le nom de la ville.

à Partir d'un Geocoder objet, vous pouvez appeler la getFromLocation(double, double, int) la méthode. Il retournera une liste d'objets Address qui ont une méthode getLocality() .
Geocoder gcd = new Geocoder(context, Locale.getDefault());
List<Address> addresses = gcd.getFromLocation(lat, lng, 1);
if (addresses.size() > 0) {
System.out.println(addresses.get(0).getLocality());
}
else {
// do your stuff
}

j'utilise ce code. Vous pouvez également votre ceci pour obtenir la ville et d'autres détails sur une Latitude et longitude :
public class getReverseGeoCoding {
private String Address1 = "", Address2 = "", City = "", State = "", Country = "", County = "", PIN = "";
public void getAddress() {
Address1 = "";
Address2 = "";
City = "";
State = "";
Country = "";
County = "";
PIN = "";
try {
JSONObject jsonObj = parser_Json.getJSONfromURL("http://maps.googleapis.com/maps/api/geocode/json?latlng=" + Global.curLatitude + ","
+ Global.curLongitude + "&sensor=true");
String Status = jsonObj.getString("status");
if (Status.equalsIgnoreCase("OK")) {
JSONArray Results = jsonObj.getJSONArray("results");
JSONObject zero = Results.getJSONObject(0);
JSONArray address_components = zero.getJSONArray("address_components");
for (int i = 0; i < address_components.length(); i++) {
JSONObject zero2 = address_components.getJSONObject(i);
String long_name = zero2.getString("long_name");
JSONArray mtypes = zero2.getJSONArray("types");
String Type = mtypes.getString(0);
if (TextUtils.isEmpty(long_name) == false || !long_name.equals(null) || long_name.length() > 0 || long_name != "") {
if (Type.equalsIgnoreCase("street_number")) {
Address1 = long_name + " ";
} else if (Type.equalsIgnoreCase("route")) {
Address1 = Address1 + long_name;
} else if (Type.equalsIgnoreCase("sublocality")) {
Address2 = long_name;
} else if (Type.equalsIgnoreCase("locality")) {
// Address2 = Address2 + long_name + ", ";
City = long_name;
} else if (Type.equalsIgnoreCase("administrative_area_level_2")) {
County = long_name;
} else if (Type.equalsIgnoreCase("administrative_area_level_1")) {
State = long_name;
} else if (Type.equalsIgnoreCase("country")) {
Country = long_name;
} else if (Type.equalsIgnoreCase("postal_code")) {
PIN = long_name;
}
}
// JSONArray mtypes = zero2.getJSONArray("types");
// String Type = mtypes.getString(0);
// Log.e(Type,long_name);
}
}
} catch (Exception e) {
e.printStackTrace();
}
}
public String getAddress1() {
return Address1;
}
public String getAddress2() {
return Address2;
}
public String getCity() {
return City;
}
public String getState() {
return State;
}
public String getCountry() {
return Country;
}
public String getCounty() {
return County;
}
public String getPIN() {
return PIN;
}
}
JSON PARSER CLASS
public class parser_Json {
public static JSONObject getJSONfromURL(String url) {
// initialize
InputStream is = null;
String result = "";
JSONObject jObject = null;
// http post
try {
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(url);
HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();
is = entity.getContent();
} catch (Exception e) {
Log.e("log_tag", "Error in http connection " + e.toString());
}
// convert response to string
try {
BufferedReader reader = new BufferedReader(new InputStreamReader(is, "iso-8859-1"), 8);
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
is.close();
result = sb.toString();
} catch (Exception e) {
Log.e("log_tag", "Error converting result " + e.toString());

// try parse the string to a JSON object
try {

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

j'ai une nouvelle façon de résoudre ce problème. Ici, j'ai utilisé le service http de google pour obtenir des informations totales de localisation basée sur la longitude et la latitude. Vous avez juste besoin de passer la latitude et la longitude dans l'url et votre clé api (ex : latlng=21.1497409, 79.087479700002 & clé=votre clé API). Voici mon obtenir le service dans ExampleService Classe
getService(url) {
return this.http.get(url).map((data: any) => data.json())
}
ce que vous pouvez mettre n'importe où vous voulez et il suffit d'appeler ci-dessous service à partir du composant où vous avez besoin de données de localisation
this._exampleService.getService("https://maps.googleapis.com/maps/api/geocode/json?latlng=21.1497409, 79.08747970000002&key=YOUR API KEY").subscribe(getplaceData => {
var placeDataDest: any;
placeDataDest = getplaceData;
console.log("i got place id yeee " + placeDataDest['results'][0]['place_id']);
console.log("i got place details yeee " + placeDataDest['results']);
});
trouver également le nom de la ville....j'espère que vous trouverez cet utile
