android解析json时动态获取key

最近项目中有解析json的时候,本来应该很快解决的,但是一看发过来的json数据,

我的乖乖,json数据好多啊有点复杂,关键是这个key是不一定,网上

找了一下,确实有这样的需求和我的一样,于是应用到自己的项目中

贴一下我的json数据:

{"column": 6, 
	"map": 
	    {"5-4":{"check_name": "-", "ip": "192.168.103.174", "num": 23, "group": 0},

下面贴代码:

                               JSONObject jsonObject = new JSONObject(jString);
int column = jsonObject.getInt("column");
int row = jsonObject.getInt("row");
JSONObject mapJSON = jsonObject.getJSONObject("map");

                                // 动态获取key值
Iterator iterator = mapJSON.keys();
while (iterator.hasNext()) {
key = iterator.next();
JSONObject keyJSON = mapJSON.getJSONObject(key);
String stu_name = keyJSON.getString("check_name");
String stu_ip = keyJSON.getString("ip");
int num = keyJSON.getInt("num");
int group = keyJSON.getInt("group");
}

嗯,就是这样子
