我想从此JSON数据中过滤JSON。

{
"place_id":"334147340966",
"osm_type":"node",
"osm_id":"3195103137",
"licence":"https:\/\/locationiq.com\/attribution",
"lat":"37.422283",
"lon":"-122.083944",
"display_name":"Charlie's cafe, Charleston Terrace, Mountain View, Santa Clara County, Kalifornien, 94043, Vereinigte Staaten",
"boundingbox":["37.422283","37.422283","-122.083944","-122.083944"],
"importance":0.2,
"address":{"name":"Charlie's cafe","neighbourhood":"Charleston Terrace","city":"Mountain View","county":"Santa Clara County","state":"Kalifornien","postcode":"94043","country":"Vereinigte Staaten","country_code":"us"}

}

码

  try {
                JSONArray lists = new JSONArray(jsonStr);
                for (int i = 0; i < lists.length(); i++) {
                    JSONObject c = lists.getJSONObject(i);
                    address = c.getString("adress");
                }
                System.out.println(address);
            } catch (JSONException e) {
                e.printStackTrace();
        }

JSON数据

我想从关键地址获取值，然后在控制台上打印

最佳答案

因此，您的“地址”实际上本身就是一个JSON对象。
做这个：

try {

JSONObject mainObject = new JSONObject(jsonStr);
JSONObject adressObject = mainObject.getJSONObject("adress");

//now extract all the values in adress like this
String name = adressObject.getString("name");
String neighbourhood = adressObject.getString("neighbourhood");
String city = adressObject.getString("city");
String county = adressObject.getString("county");
String state = adressObject.getString("state");
String postcode = adressObject.getString("postcode");
String postcode = adressObject.getString("postcode");
String country_code = adressObject.getString("country_code");


} catch (JSONException e) {
e.printStackTrace();
}
