Bir şehrin veya bölgenin enlem ve boylam koordinatlarına sahipsem, şehir adını Google Haritalar'da nasıl elde edebilirim?
Enlem, boylam kullanmayı denedim ve ülkem var ama şehir adını nasıl alacağımı bilmiyorum.

Yanıtlar:
Bir Geocodernesneden getFromLocation(double, double, int)yöntemi çağırabilirsiniz . AddressYöntemi olan nesnelerin bir listesini döndürür 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
}
Bu kodu kullanıyorum. Bunu ayrıca bir Enlem ve boylamla ilgili şehir ve diğer ayrıntıları almak için de yapabilirsiniz:
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&key=YOUR_API_KEY");
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 != "") {

Bu sorunu çözmenin yeni bir yolunu buldum. Burada, boylam ve enleme dayalı toplam konum bilgisini almak için google http hizmetini kullandım. Sadece url'de ve api anahtarınızda enlem ve boylamı iletmeniz gerekir (örn: latlng = 21.1497409, 79.08747970000002 & key = API ANAHTARINIZ). İşte benim sınıfta hizmet ExampleServicealmam
getService(url) {
return this.http.get(url).map((data: any) => data.json())
}bunu istediğiniz yere koyabilirsiniz ve konum verilerine ihtiyaç duyduğunuz bileşenden aşağıdaki servisi aramanız yeterlidir.
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']);
});benzer şekilde şehir adını bulun .... bunu faydalı bulacağınızı umuyoruz
Lütfen aşağıdaki koda bakın
Geocoder geocoder = new Geocoder(this, Locale.getDefault());
List<Address> addresses = geocoder.getFromLocation(latitude, longitude, 1);
String cityName = addresses.get(0).getAddressLine(0);
String stateName = addresses.get(0).getAddressLine(1);
String countryName = addresses.get(0).getAddressLine(2);Bir listeniz varsa bunu kullanabilirsiniz:
Address address = list.get(0);
String cityname = address.getLocality(); com.alibaba.fastjson.JSONObject jsonObject = com.alibaba.fastjson.JSONObject.parseObject(data);
if("OK".equals(jsonObject.getString("status"))){
String formatted_address;
JSONArray results = jsonObject.getJSONArray("results");
if(results != null && results.size() > 0){
com.alibaba.fastjson.JSONObject object = results.getJSONObject(0);
String addressComponents = object.getString("address_components");
formatted_address = object.getString("formatted_address");
Log.e("amaya","formatted_address="+formatted_address+"--url="+url);
if(findCity){
boolean finded = false;
JSONArray ac = JSONArray.parseArray(addressComponents);
if(ac != null && ac.size() > 0){
for(int i=0;i<ac.size();i++){
com.alibaba.fastjson.JSONObject jo = ac.getJSONObject(i);
JSONArray types = jo.getJSONArray("types");
if(types != null && types.size() > 0){
for(int j=0;j<ac.size();j++){
String string = types.getString(i);
if("administrative_area_level_1".equals(string)){
finded = true;
break;
}
}
}
if(finded) break;
}
}
Log.e("amaya","city="+formatted_address);
}else{
Log.e("amaya","poiName="+hotspotPoi.getPoi_name()+"--"+hotspotPoi);
}
if(hotspotPoi != null) hotspotPoi.setPoi_name(formatted_address);
EventBus.getDefault().post(new AmayaEvent.GeoEvent(hotspotPoi));
}
}bu, google geri bildirim verilerini ayrıştırmak için bir yöntemdir.

}Brezilya'dayım. Bölgesel detaylardan dolayı bazen şehir farklı şekillerde anılır. Hindistan ve diğer ülkelerde de aynı olduğunu düşünüyorum. Bu yüzden, hataları önlemek için şu doğrulamayı yapıyorum:
private fun getAddress(latLng: LatLng): String {
// 1
val geocoder = Geocoder(this)
val addresses: List<Address>?
var city = "no"
try {
addresses = geocoder.getFromLocation(latLng.latitude, latLng.longitude, 1)
if (null != addresses && !addresses.isEmpty()) { //prevent from error
//sometimes the city comes in locality, sometimes in subAdminArea.
if (addresses[0].locality == null) {
city = addresses[0].subAdminArea
} else {
city = addresses[0].locality
}
}
} catch (e: IOException) {
Log.e("MapsActivity", e.localizedMessage)
}
return city
}Şehrin "hayır" döndürüp döndürmediğini de kontrol edebilirsiniz. Öyleyse, kullanıcının konumunu almak mümkün değildi. Umarım yardımcı olur.
