在j2me应用里用json.me解析json

最近在写一个手机的应用，主要就是解析服务器返回的json。本来服务器是支持xml和json两种数据的，但发现用kxml做解析，研究了半晚还是没搞明白（鄙视自己一下:>）,于是改用json的数据了。

 

json 数据的格式

哈哈是不是看的有点晕，实际就是饭否API返回的数据啦。http://api.fanfou.com/statuses/user_timeline.json

 

下面是具体的代码 Msg.java

存放解析出的json数据的

public class Msg { private String id; private String msg; private String profileImg; private String uid; private String name; private String createtime; public void setId(String id){ this.id = id; } public String getId(){ return id; } public void setMsg(String msgstr){ msg = msgstr; } public String getMsg(){ return msg; }

 

 

这里就是怎么使用json.me了

import org.json.me.*; ... Vector msgs = new Vector(); ... JSONArray ja = new JSONArray (jsonstr); if (ja != null) { for(int i=0;i<ja.length();i++){ JSONObject ino = ja.optJSONObject(i); if(ino != null){ Msg msg = new Msg(); String id = ino.getString("id"); String user = ino.getString("user"); msg.setId(id); msg.setMsg(ino.getString("text")); JSONObject inner = new JSONObject(user); if(inner != null){ msg.setUid(inner.getString("id")); msg.setName(inner.getString("name")); msg.setProfileImg(inner.getString("profile_image_url")); } msgs.addElement(msg); } } }
