android 将json转换为bean

 1，写一个序列化数据的bean类，例如：

public class TestInfoBean {

    public String status;

    public String message;

    public List<TestInfoBean.Bean2> data = new ArrayList<>();

    public static class Bean2 {

        public String groupCode;
        public String groupName;
        public String id;
        public List<TestInfoBean.Bean1> ListGroups = new ArrayList<>();
    }

    public static class Bean1 {

        public String groupCode;
        public String groupName;
        public String id;
        public List<TestInfoBean.Bean> ListGroups = new ArrayList<>();
    }

    public static class Bean {

        public String groupCode;
        public String groupName;
        public String id;
    }
}

2，将从服务器后台获取到的json格式的string数据，转化为序列化数据bean，方法如下： 

   /**
     * 将json转换为bean
     * @param json
     * @return
     */
    public TestInfoBean transformJsonToBean(JSONObject json) {
        TestInfoBean Bean = new TestInfoBean();

        Bean = new Gson().fromJson(json.toString(), TestInfoBean.class);

        for (TestInfoBean.Bean2 bean: Bean.data){
            Log.d("test", bean.toString());
        }
        return Bean;
    }

3，调用如下

TestInfoBean Bean = transformJsonToBean(result);
