json数据解析

 1 json数据格式解析我自己分为两种；
 2 
 3 一种是普通的，一种是带有数组形式的；

 7 
 8 普通形式的：
 9 服务器端返回的json数据格式如下：
10 
11 {"userbean":{"Uid":"100196","Showname":"u75afu72c2u7684u7334u5b50","Avtar":null,"State":1}}
12 
13 分析代码如下：
14 
15 // TODO 状态处理 500 200 
16                 int res = 0; 
17                 res = httpClient.execute(httpPost).getStatusLine().getStatusCode(); 
18                 if (res == 200) { 
19                     /* 
20                      * 当返回码为200时，做处理 
21                      * 得到服务器端返回json数据，并做处理 
22                      * */ 
23                     HttpResponse httpResponse = httpClient.execute(httpPost); 
24                     StringBuilder builder = new StringBuilder(); 
25                     BufferedReader bufferedReader2 = new BufferedReader( 
26                             new InputStreamReader(httpResponse.getEntity().getContent())); 
27                     String str2 = ""; 
28                     for (String s = bufferedReader2.readLine(); s != null; s = bufferedReader2 
29                             .readLine()) { 
30                         builder.append(s); 
31                     } 
32                     Log.i("cat", ">>>>>>" + builder.toString());
33 
34 JSONObject jsonObject = new JSONObject(builder.toString()) 
35                         .getJSONObject("userbean"); 
36 
37                 String Uid; 
38                 String Showname; 
39                 String Avtar; 
40                 String State; 
41 
42                 Uid = jsonObject.getString("Uid"); 
43                 Showname = jsonObject.getString("Showname"); 
44                 Avtar = jsonObject.getString("Avtar"); 
45                 State = jsonObject.getString("State");
46 带数组形式的：
47 服务器端返回的数据格式为：
48 
49 {"calendar": 
50     {"calendarlist": 
51             [ 
52             {"calendar_id":"1705","title":"(u4eb2u5b50)ddssd","category_name":"u9ed8u8ba4u5206u7c7b","showtime":"1288927800","endshowtime":"1288931400","allDay":false}, 
53             {"calendar_id":"1706","title":"(u65c5u884c)","category_name":"u9ed8u8ba4u5206u7c7b","showtime":"1288933200","endshowtime":"1288936800","allDay":false} 
54             ] 
55     } 
56 }
57 
58 分析代码如下：
59 
60 // TODO 状态处理 500 200 
61                 int res = 0; 
62                 res = httpClient.execute(httpPost).getStatusLine().getStatusCode(); 
63                 if (res == 200) { 
64                     /* 
65                      * 当返回码为200时，做处理 
66                      * 得到服务器端返回json数据，并做处理 
67                      * */ 
68                     HttpResponse httpResponse = httpClient.execute(httpPost); 
69                     StringBuilder builder = new StringBuilder(); 
70                     BufferedReader bufferedReader2 = new BufferedReader( 
71                             new InputStreamReader(httpResponse.getEntity().getContent())); 
72                     String str2 = ""; 
73                     for (String s = bufferedReader2.readLine(); s != null; s = bufferedReader2 
74                             .readLine()) { 
75                         builder.append(s); 
76                     } 
77                     Log.i("cat", ">>>>>>" + builder.toString()); 
78                     /** 
79                      * 这里需要分析服务器回传的json格式数据， 
80                      */ 
81                     JSONObject jsonObject = new JSONObject(builder.toString()) 
82                             .getJSONObject("calendar"); 
83                     JSONArray jsonArray = jsonObject.getJSONArray("calendarlist"); 
84                     for(int i=0;i<jsonArray.length();i++){ 
85                         JSONObject jsonObject2 = (JSONObject)jsonArray.opt(i); 
86                         CalendarInfo calendarInfo = new CalendarInfo(); 
87                         calendarInfo.setCalendar_id(jsonObject2.getString("calendar_id")); 
88                         calendarInfo.setTitle(jsonObject2.getString("title")); 
89                         calendarInfo.setCategory_name(jsonObject2.getString("category_name")); 
90                         calendarInfo.setShowtime(jsonObject2.getString("showtime")); 
91                         calendarInfo.setEndtime(jsonObject2.getString("endshowtime")); 
92                         calendarInfo.setAllDay(jsonObject2.getBoolean("allDay")); 
93                         calendarInfos.add(calendarInfo); 
94                     }
95 
96 总结，普通形式的只需用JSONObject ，带数组形式的需要使用JSONArray 将其变成一个list。
