JSON对象的Java表示

概述我正在尝试反序列化以下字符串,对于Java来说我是新手,我无法在我的一生中使用它…我现在仅尝试在对象中解码两个字符串.我的JSON和Java类如下.我得到的结果变量确定.{"result":"true","recentlyMarkedTerritories":{"0":{"pk_activity":"471",

我正在尝试反序列化以下字符串,对于Java来说我是新手,我无法在我的一生中使用它…我现在仅尝试在对象中解码两个字符串.我的JSON和java类如下.我得到的结果变量确定.

{   "result": "true",   "recentlyMarkedTerritorIEs": {      "0": {         "pk_activity": "471",         "fk_activity_type": "100",         "activity_content": "Hhhhh",         "fk_user": "2",         "activity_image": "2_QZe73f4t8s3R1317230457.jpg",         "created": "1317244857",         "activity_status": "1",         "activity_location_lat": "43.515283",         "activity_location_lon": "-79.880678",         "fk_walk": null,         "fk_event_location": "73",         "user_point": "0",         "public_image": "0",         "fk_event_location_lat": "43.515273",         "fk_event_location_lon": "-79.879989",         "profile_image": "2_y9JlkI3CZDml1312492743.jpg",         "user_gender": "1",         "user_dob": "236073600",         "user_nickname": "junoman",         "isFrIEnd": "false",         "profile_image_thumb": "2_y9JlkI3CZDml1312492743_t.jpg",         "activity_image_thumb": "2_QZe73f4t8s3R1317230457_t.jpg",         "relationship_status_IDx": "2",         "isBlocked": "false"      },      "1": {         "pk_activity": "469",         "fk_activity_type": "100",         "activity_content": "JsJsJs",         "fk_user": "1",         "activity_image": null,         "created": "1317244508",         "activity_status": "1",         "activity_location_lat": "43.515283",         "activity_location_lon": "-79.880678",         "fk_walk": null,         "fk_event_location": "73",         "user_point": "0",         "public_image": "0",         "fk_event_location_lat": "43.515273",         "fk_event_location_lon": "-79.879989",         "profile_image": "1_4Cpkofueqnrb1316895161.jpg",         "user_gender": "1",         "user_dob": "116841600",         "user_nickname": "JoePennington",         "isFrIEnd": "false",         "profile_image_thumb": "1_4Cpkofueqnrb1316895161_t.jpg",         "activity_image_thumb": null,         "relationship_status_IDx": "1",         "isBlocked": "false"      },      .....   }}

还有我下面的java类

RecentActivity infoList = null;Gson gson = new Gson();infoList = gson.fromJson(JsONString, RecentActivity.class);public class RecentActivity {    String result;    recentlyMarkedTerritorIEs recentlyMarkedTerritorIEs = null;    public RecentActivity() {    }    public class recentlyMarkedTerritorIEs {        public Set<recentlyMarkedTerritorIEs> pk_activity = new HashSet<recentlyMarkedTerritorIEs>() ;        public recentlyMarkedTerritorIEs() {    }    }}

请原谅我缺乏描述,但我确信代码会有所帮助. JsON已在其他应用程序中使用,因此不可更改.

谢谢！

解决方法:

这是一些不错的JsON教程,可以帮助您.

更新

这样尝试

 try {            JsONObject object = new JsONObject(JsonString);            JsONObject myObject = object.getJsONObject("recentlyMarkedTerritorIEs");            for (int i = 0; i < object.length(); i++) {                JsONObject myObject2 = myObject.getJsONObject(Integer.toString(i));                System.out.println(myObject2.toString(2));              }        } catch (Exception e) {            e.printstacktrace();        }
