android 解析json数据格式

json数据格式解析我自己分为两种；

一种是普通的，一种是带有数组形式的；




普通形式的：
服务器端返回的json数据格式如下：

{"userbean":{"Uid":"100196","Showname":"\u75af\u72c2\u7684\u7334\u5b50","Avtar":null,"State":1}}

分析代码如下：

// TODO 状态处理 500 200 
int res = 0; 
res = httpClient.execute(httpPost).getStatusLine().getStatusCode(); 
if (res == 200) { 
/* 
* 当返回码为200时，做处理 
* 得到服务器端返回json数据，并做处理 
* */ 
HttpResponse httpResponse = httpClient.execute(httpPost); 
StringBuilder builder = new StringBuilder(); 
BufferedReader bufferedReader2 = new BufferedReader( 
new InputStreamReader(httpResponse.getEntity().getContent())); 
String str2 = ""; 
for (String s = bufferedReader2.readLine(); s != null; s = bufferedReader2 
.readLine()) { 
builder.append(s); 
} 
Log.i("cat", ">>>>>>" + builder.toString());

JSONObject jsonObject = new JSONObject(builder.toString()) 
.getJSONObject("userbean"); 

String Uid; 
String Showname; 
String Avtar; 
String State; 

Uid = jsonObject.getString("Uid"); 
Showname = jsonObject.getString("Showname"); 
Avtar = jsonObject.getString("Avtar"); 
State = jsonObject.getString("State");
带数组形式的：
服务器端返回的数据格式为：

{"calendar": 
{"calendarlist": 
[ 
{"calendar_id":"1705","title":"(\u4eb2\u5b50)ddssd","category_name":"\u9ed8\u8ba4\u5206\u7c7b","showtime":"1288927800","endshowtime":"1288931400","allDay":false}, 
{"calendar_id":"1706","title":"(\u65c5\u884c)","category_name":"\u9ed8\u8ba4\u5206\u7c7b","showtime":"1288933200","endshowtime":"1288936800","allDay":false} 
] 
} 
}

分析代码如下：

// TODO 状态处理 500 200 
int res = 0; 
res = httpClient.execute(httpPost).getStatusLine().getStatusCode(); 
if (res == 200) { 
/* 
* 当返回码为200时，做处理 
* 得到服务器端返回json数据，并做处理 
* */ 
HttpResponse httpResponse = httpClient.execute(httpPost); 
StringBuilder builder = new StringBuilder(); 
BufferedReader bufferedReader2 = new BufferedReader( 
new InputStreamReader(httpResponse.getEntity().getContent())); 
String str2 = ""; 
for (String s = bufferedReader2.readLine(); s != null; s = bufferedReader2 
.readLine()) { 
builder.append(s); 
} 
Log.i("cat", ">>>>>>" + builder.toString()); 
/** 
* 这里需要分析服务器回传的json格式数据， 
*/ 
JSONObject jsonObject = new JSONObject(builder.toString()) 
.getJSONObject("calendar"); 
JSONArray jsonArray = jsonObject.getJSONArray("calendarlist"); 
for(int i=0;i<jsonArray.length();i++){ 
JSONObject jsonObject2 = (JSONObject)jsonArray.opt(i); 
CalendarInfo calendarInfo = new CalendarInfo(); 
calendarInfo.setCalendar_id(jsonObject2.getString("calendar_id")); 
calendarInfo.setTitle(jsonObject2.getString("title")); 
calendarInfo.setCategory_name(jsonObject2.getString("category_name")); 
calendarInfo.setShowtime(jsonObject2.getString("showtime")); 
calendarInfo.setEndtime(jsonObject2.getString("endshowtime")); 
calendarInfo.setAllDay(jsonObject2.getBoolean("allDay")); 
calendarInfos.add(calendarInfo); 
}

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。
