android 微博数据请求,android腾讯微博开发04-json数据解析，获取微博列表

上篇已完成了微博的发送，接下来我们就以“主页时间线来获取微博”

1.首先，根据返回的json微博数据，我们需要对json数据进行解析

返回的json数据格式如下：

{"data":

{

"hasnext":0,

"info":[

{

"city_code":"2",

"count":0,

"country_code":"1",

"emotiontype":0,

"emotionurl":"",

"from":"微博开放平台",

"fromurl":"http:\/\/wiki.open.t.qq.com\/index.php\/产品类FAQ#.E6.8F.90.E4.BA.A4.E5.BA.94.E7.94.A8.E6.9D.A5.E6.BA.90.E5.AD.97.E6.AE.B5.E5.AE.A1.E6.A0.B8.E8.83.BD.E5.BE.97.E5.88.B0.E4.BB.80.E4.B9.88.E5.A5.BD.E5.A4.84.EF.BC.9F\u000a","geo":"","head":"","id":"179515026443503",

"image":null,

"isrealname":2,

"isvip":0,

"jing":"0",

"latitude":"0",

"location":"中国 湖南 株洲",

"longitude":"0",

"mcount":0,

"music":null,

"name":"xiexieni4185",

"nick":"谢谢你",

"openid":"7CE51577F1CD290A03784DB817622898",

"origtext":"yyyyyy",

"province_code":"43",

"self":1,

"source":null

,"status":0,

"text":"yyyyyy",

"timestamp":1355600954,

"type":1,

"video":null,

"wei":"0"

}

],

"timestamp":1355600965,

"user":{

"xiexieni4185":"谢谢你"

}

},

"errcode":0,

"msg":"ok",

"ret":0,

"seqid":5822261811111418032

}

-------------------------分析 ：

{"data":

{

"hasnext":0,

"info":[

{},

{}

],

"timestamp":1355600965,

"user":{

"xiexieni4185":"谢谢你"

}

},

"errcode":0,

"msg":"ok",

"ret":0,

"seqid":5822261811111418032

}

json数据解析的工具类代码：

package com.xgh.tencent.weibo.data.util;

import java.util.ArrayList;

import java.util.List;

import org.json.JSONArray;

import org.json.JSONException;

import org.json.JSONObject;

import com.xgh.tencent.weibo.beans.Blog;

import com.xgh.tencent.weibo.beans.Data;

import com.xgh.tencent.weibo.beans.DataContext;

import com.xgh.tencent.weibo.beans.Info;

import com.xgh.tencent.weibo.beans.User;

public class JSONParser {

public static Data getData(String jsonString)

{

List blogList = new

ArrayList();

// 获取最上层json数据对象

JSONObject dataContextJO =

parseJSONString(jsonString);

// 创建数组上下文对象

DataContext dataContext = new

DataContext();

Data data = null;

try {

dataContext.errcode

= dataContextJO.getString("errcode");

dataContext.msg

= dataContextJO.getString("msg");

dataContext.ret

= dataContextJO.getString("ret");

dataContext.seqid

= dataContextJO.getString("seqid");

//

创建Data对象

data = new Data();

JSONObject

dataJO = dataContextJO.getJSONObject("data");

data.context

= dataContext;

data.hasnext

= dataJO.getString("hasnext");

data.timestamp

= dataJO.getString("timestamp");

// 获取用户

JSONObject

userJO = dataJO.getJSONObject("user");

//

创建User对象

User user =

new User();

//

..暂时不解析

//

解析Info

JSONArray

infoJA = dataJO.getJSONArray("info");

//

创建Info对象

Info info =

new Info();

//

解析BlogList

JSONObject

jsonObj = null;

for (int i =

0; i < infoJA.length(); i++) {

Blog

blog = new Blog();

jsonObj

= infoJA.getJSONObject(i);

blog.id

= jsonObj.getString("id");

blog.text

= jsonObj.getString("text");

blog.origtext

= jsonObj.getString("origtext");

blog.openid

= jsonObj.getString("openid");

blog.nick

= jsonObj.getString("nick");

blog.name

= jsonObj.getString("name");

blog.timestamp

= jsonObj.getString("timestamp");

blog.count

= jsonObj.getString("count");

blog.from

= jsonObj.getString("from");

blog.fromurl

= jsonObj.getString("fromurl");

blog.self

= jsonObj.getString("self");

blog.status

= jsonObj.getString("status");

blog.location

= jsonObj.getString("location");

blog.latitude

= jsonObj.getString("latitude");

blog.longitude

= jsonObj.getString("longitude");

//

添加到博客列表

blogList.add(blog);

}

info.blogs =

blogList;

//

设置数据关系

data.context

= dataContext;

data.user =

user;

data.info =

info;

} catch (JSONException e)

{

e.printStackTrace();

}

return data;

}

public static List getBlogList(Data data) {

return data.info.blogs;

}

public static JSONObject parseJSONString(String

jsonString) {

JSONObject jsonObj =

null;

try {

jsonObj = new

JSONObject(jsonString);

} catch (JSONException e) {

e.printStackTrace();

}

return jsonObj;

}

}

----------------------------------------------------------

根据返回的微博JSON数据，自定义的一些模型类：

微博model类：

package com.xgh.tencent.weibo.beans;

import java.util.Date;

public class Blog {

public String name; //似为昵称拼音

public String city_code; //城市码

public String count; //微博被转发的次数

public String text; //微博内容

public String origtext; //原始内容

public String mcount; //点评次数

public String

from; //微博来源

public String fromurl; //来源url

public String

id; //微博唯一id

public String image; //图片url列表

public String status;

//微博状态，0-正常，1-系统删除，2-审核中，3-用户删除，4-根删除(根节点被系统审核删除)

public String nick; //用户昵称

public String openid; //用户openid

public String provicen_code; //省代码

public String self; //是否自已发的的微博，0-不是，1-是

public

String head; //发表者头像url;

public

String timestamp; //发表时间

public

String latitude ; //经度

public

String longitude; //纬度

public

String location; //位置

public Video video; //视频信息

public Music music; //音频信息

public String toString(){

return

"id:"+id+",openid:"+openid+",name:"+name+",nick:"+nick

+",text:"+text+",origtext:"+origtext+",self:"+self+

",status:"+status+",timestamp:"+timestamp+",from:"+from

+",location:"+location+",count:"+count+",fromurl:"+fromurl;

}

public String getGeneralShowMsg(){

return origtext+","+nick+","+

timestamp;

}

}

------------------------------------------------

package com.xgh.tencent.weibo.beans;

public class Data {

public String timestamp; //时间线

public String hasnext; //是否还有，0表示有

public User user; //用户信息

public Info info; //信息，包含博客内容列表

public DataContext context; //数组上下文信息

public String toString(){

return

"hasnext:"+hasnext+",timestamp:"+timestamp

+",user{"+user.toString()+"},info{"+info.toString()

+"},context{"+context.toString()+"}";

}

}

------------------------------------------------------------

package com.xgh.tencent.weibo.beans;

public class DataContext { public

String errcode; //错误码 , 0表示正常返回

public

String

msg; //返回信息，正常时返回"ok"

public

String

ret; //正常时，返回0

public

String seqid; //序列id

public

String toString(){

return

"errcode:"+errcode+",msg:"+msg

+",ret:"+ret+",seqid:"+seqid

;

}

}

------------------------------------------------

package com.xgh.tencent.weibo.beans;

import java.util.List;

public class Info {

public List

blogs; //微博数组

public

String toString(){

if(blogs==null||blogs.size()==0)

return "{null}";

StringBuffer buff = new StringBuffer("{");

for(Blog blog: blogs){

buff.append(blog.toString()).append(",");

}

buff.append("}");

return buff.toString();

}

}

--------------------------------------------

package com.xgh.tencent.weibo.beans;

public class User {

public String name; //用户名

public String nick; //昵称

public String toString(){

return

"name:"+name+",nick:"+nick;

}

}

----------------------------------------

package com.xgh.tencent.weibo.beans;

public class Music {

}

-------------------------------------------

package com.xgh.tencent.weibo.beans;

public class Image {

}

---------------------------------------------

package com.xgh.tencent.weibo.beans;

public class Video {

}

另外，还有一个临时的BeanUtil类：

package com.xgh.tencent.weibo.data.util;

import java.util.ArrayList;

import java.util.List;

import com.xgh.tencent.weibo.beans.Blog;

public class BeanUtil {

public static

List

objectToStringList(List extends

Object> list){

List result = new

ArrayList();

for(Object obj:list){

result.add(obj.toString());

}

return result;

}

public static

List

getBlogStringList(List

blogs){

List result = new

ArrayList();

for(Blog obj:blogs){

result.add(obj.getGeneralShowMsg());

}

return result;

}

}
