android中用jsonObject解析json資料__js

json資料格式解析我自己分為兩種；
一種是普通的，一種是帶有數組形式的；
普通形式的：
伺服器端返回的json資料格式如下：
{ " userbean " :{ " Uid " : " 100196 " , " Showname " : " \u75af\u72c2\u7684\u7334\u5b50 " , " Avtar " : null , " State " : 1 }}
分析代碼如下：
// TODO 狀態處理 500 200
int res = 0 ;
res = httpClient.execute(httpPost).getStatusLine().getStatusCode();
if (res == 200 ) {
/*
* 當返回碼為200時，做處理
* 得到伺服器端返回json資料，並做處理
* */
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 " );
帶數組形式的：
伺服器端返回的資料格式為：
{ " 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 }
]
}
}
分析代碼如下：
// TODO 狀態處理 500 200
int res = 0 ;
res = httpClient.execute(httpPost).getStatusLine().getStatusCode();
if (res == 200 ) {
/*
* 當返回碼為200時，做處理
* 得到伺服器端返回json資料，並做處理
* */
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());
/**
* 這裡需要分析伺服器回傳的json格式資料，
*/
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);
}
總結，普通形式的只需用JSONObject ，帶數組形式的需要使用JSONArray 將其變成一個list。
