Json解析要点

解析Json时，昨天遇到了新的问题，之前都是解析的数组，不是数组的用类来做。

这是Json串;

{"status":"00001","ver":"1.0","msg":"ok","result":{"init_id":"13","init_time":"2015-12-30 00:00:00","init_title":"\u7bee\u7403\u7ea6\u67b6","init_lati":"31.19","init_longti":"120.37","init_location":"\u82cf\u5dde","commit_init_users":[{"commits_id":"25","commit_images":{"pub_img":["Public\/dd\/201512\/22\/5678ad286dfb8.jpg"],"pub_th_img":["Public\/dd\/thumb\/antu_5678ad286dfb8.jpg"]},"user_id":"1234648","user_head_url":"Public\/tmp\/7004.jpg","commits_time":"2015-12-30 00:00:00","commits_comments":" \u77ed\u53d1\n","commits_flg":"0","count":1},{"commits_id":"26","commit_images":{"pub_img":["Public\/dd\/201512\/22\/5678ad30337d8.jpg"],"pub_th_img":["Public\/dd\/thumb\/antu_5678ad30337d8.jpg"]},"user_id":"1234649","user_head_url":"Public\/tmp\/7005.jpg","commits_time":"2015-12-20 00:00:00","commits_comments":"\u5404\u4f4d\n","commits_flg":"0","count":1},{"commits_id":"40","commit_images":{"pub_img":["Public\/dd\/201512\/22\/5678ac6ec7a53.jpg","Public\/dd\/201512\/22\/5678ac7535f56.jpg"],"pub_th_img":["Public\/dd\/thumb\/antu_5678ac6ec7a53.jpg","Public\/dd\/thumb\/antu_5678ac7535f56.jpg"]},"user_id":"1234648","user_head_url":"Public\/tmp\/7004.jpg","commits_time":"2015-12-30 00:00:00","commits_comments":"\u7bee\u7403\u7ea6\u67b6","commits_flg":"1","count":2}],"all_count":4}}

这是解析这条Json的JavaBean对象：

/**JavBean对象的父类
 * Created by cyc on 16-1-4.
 */
public class Response_Header_Info {
    @Expose
    public String status;//状态
    @Expose
    public String ver;//版本
    @Expose
    public String msg;//是否OK

    public String getStatus() {
        return status;
    }

    public String getVer() {
        return ver;
    }
}

/**

 * Square界面的Json对象
 * Created by cyc on 16-1-4.
 */
public class Response_Square_Callup_Recommend_Info extends Response_Header_Info {
    private static final String TAG = "Response_Square_Callup_Recommend_Info";

    /**一条广场活动的信息总和*/
    @Expose
    public Squre_Activity_all result;

    /**
     * 一条广场活动信息的总和
     */
    public class Squre_Activity_all {
        /**所有参与这个活动的用户集合*/
        @Expose
        public ArrayList<Init_users> commit_init_users;

        /**活动的图片总数*/
        @Expose
        public int image_count;
        /**发起事件ID*/
        @Expose
        public int init_id;
        /**事件的经度*/
        @Expose
        public float init_lati;
        /**事件的地点*/
        @Expose
        public String init_location;
        /**事件的纬度*/
        @Expose
        public float init_longti;
        /**发起事件的时间*/
        @Expose
        public String init_time;
        /**发起事件的标题*/
        @Expose
        public String init_title;
        /**所有参与人和发起人发起图片的总和*/
        @Expose
        public int all_count;

    }

    /**
     * 参与这个活动的用户类
     */
    public class Init_users {
        /**参与人的评论*/
        @Expose
        public String commits_comments;//字段仔细别写错
        /**是否活动发起人*/
        @Expose
        public int commits_flg;
        /**参与发起的ID*/
        @Expose
        public int commits_id;
        /**参与发起的时间*/
        @Expose
        public String commits_time;
        /**参与事件人的头像*/
        @Expose
        public String user_head_url;
        /**用户的ID*/
        @Expose
        public int user_id;
        /**发布图片的数量*/
        @Expose
        public int count;

        /**参与人发的所有图片的类*/
        @Expose
        public Img commit_images;
    }
    /**参与人发的图片(缩略图和大图)*/
    public class Img{
        /**大图集合*/
        @Expose
        public ArrayList<String> pub_img;
        /**缩略图集合*/
        @Expose
        public ArrayList<String> pub_th_img;
    }
}

根据这个Json串的解析，绝大多数的Json都是这样解析的,一定要小心字段别写错了，要点： { 开头的字段用类来描述　　　　[ 开头的字段用集合来描述
