Gson - Getting value from JSON string

Question

I have the following JSON string. I want to fetch formatted_address with the help of Gson library. I have done conversion of object to JSON. But this time want to get a value of a particular key and store it in a string.

{
   "results" : [
      {
         "address_components" : [
            {
               "long_name" : "Mumbai Highway",
               "short_name" : "NH 9",
               "types" : [ "route" ]
            },
            {
               "long_name" : "Kumar Swamy Nagar",
               "short_name" : "Kumar Swamy Nagar",
               "types" : [ "sublocality_level_1", "sublocality", "political" ]
            },
            {
               "long_name" : "Solapur",
               "short_name" : "Solapur",
               "types" : [ "locality", "political" ]
            },
            {
               "long_name" : "Solapur",
               "short_name" : "Solapur",
               "types" : [ "administrative_area_level_2", "political" ]
            },
            {

               "short_name" : "IN",
               "types" : [ "country", "political" ]

               "types" : [ "postal_code" ]
            }
         ],
         "formatted_address" : "Mumbai Highway, Kumar Swamy Nagar, Solapur, Maharashtra 413002, India",
         "geometry" : {
            "bounds" : {
               "northeast" : {
                  "lat" : 17.6920319,
                  "lng" : 75.9232926
               },
               "southwest" : {

         "place_id" : "ChIJhZADyJLaxTsRj9W-lIgGaRM",
         "types" : [ "route" ]
      }
   ],
   "status" : "OK"
}

I want to parse the JSON string ang get value of "formatted_address".

Answer 1

//result is your json data in the form of string..convert json data to string.
JSONObject returnValue = new JSONObject(result);

//getting array from json
JSONArray results= returnValue.getJSONArray("results");

for (int i = 0; i < results.length(); i++) {
  JSONObject ParentObject = results.getJSONObject(i);

  //getting particular_key...
  String format_addrs=ParentObject.getString("formatted_address");     
}
