도시 나 지역의 위도와 경도 좌표가있는 경우 Google지도에서 도시 이름을 어떻게 얻을 수 있습니까?
위도, 경도를 사용해 보았고 국가가 있지만 도시 이름을 얻는 방법을 모르겠습니다.
답변
A로부터 Geocoder객체, 당신은 호출 할 수있는 getFromLocation(double, double, int)방법을. Address메서드가있는 개체 목록을 반환합니다 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
}답변
이 코드를 사용하고 있습니다. 위도 및 경도에 대한 도시 및 기타 세부 정보를 얻기 위해 이것을 사용할 수도 있습니다.
