从 Google geocode reverse API, android 获取国家名称

Question

我想获取给定纬度和经度的国家名称。我正在使用谷歌地理编码 API。我正在使用以下查询：

"http://maps.googleapis.com/maps/api/geocode/json?latlng="+lat1+","+lng1+"&sensor=true_or_false"

JSON 的结果是这样的：

{
  "status": "OK",
  "results": [ {
    "types": street_address,
    "formatted_address": "275-291 Bedford Ave, Brooklyn, NY 11211, USA",
    "address_components": [ {
      "long_name": "275-291",
      "short_name": "275-291",
      "types": street_number
    }, {
      "long_name": "Bedford Ave",
      "short_name": "Bedford Ave",
      "types": route
    }, {
      "long_name": "New York",
      "short_name": "New York",
      "types": [ "locality", "political" ]
    }, {
      "long_name": "Brooklyn",
      "short_name": "Brooklyn",
      "types": [ "administrative_area_level_3", "political" ]
    }, {
      "long_name": "Kings",
      "short_name": "Kings",
      "types": [ "administrative_area_level_2", "political" ]
    }, {
      "long_name": "New York",
      "short_name": "NY",
      "types": [ "administrative_area_level_1", "political" ]
    }, {
      "long_name": "United States",
      "short_name": "US",
      "types": [ "country", "political" ]
    }, {
      "long_name": "11211",
      "short_name": "11211",
      "types": postal_code
    } ],
    "geometry": {
      "location": {
        "lat": 40.7142298,
        "lng": -73.9614669
      },
      "location_type": "RANGE_INTERPOLATED",
      "viewport": {
        "southwest": {
          "lat": 40.7110822,
          "lng": -73.9646145
        },
        "northeast": {
          "lat": 40.7173774,
          "lng": -73.9583193
        }
      }
    }
  },

如何从这个结果中得到国家名称。

Answer 1

使用新的 Location API 来执行此操作。这是相同的教程 - https://developer.android.com/training/location/display-address.html。对于国家名称，只需在 Address 对象上调用 getCountryName()。

Answer 2

Geocoder gCoder = new Geocoder(this);
            List<Address> addresses;
            try {
                addresses = gCoder.getFromLocation(clat, clng, 5);
                Log.e("get adderess", addresses + "");
                if (addresses != null && addresses.size() > 0) {
                    addres = addresses.get(0).getLocality();
                    System.out.print(addresses.get(0).getLocality());
                }
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }

（或）

试试这个

public static String getCountryName(Context context, double latitude, double longitude) {
    Geocoder geocoder = new Geocoder(context, Locale.getDefault());
    List<Address> addresses = null;
    try {
        addresses = geocoder.getFromLocation(latitude, longitude, 1);
    } catch (IOException ignored) {
    Address result;
    if (addresses != null && !addresses.isEmpty()) {
        return addresses.get(0).getCountryName();
    }
    return null;
}
