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：
复制代码 代码如下:
{"userbean":{"Uid":"100196","Showname":"u75afu72c2u7684u7334u5b50","Avtar":null,"State":1}}
分析代码如下：
复制代码 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：
复制代码 代码如下:
{"calendar":
{"calendarlist":
[
{"calendar_id":"1705","title":"(u4eb2u5b50)ddssd","category_name":"u9ed8u8ba4u5206u7c7b","showtime":"1288927800","endshowtime":"1288931400","allDay":false},
{"calendar_id":"1706","title":"(u65c5u884c)","category_name":"u9ed8u8ba4u5206u7c7b","showtime":"1288933200","endshowtime":"1288936800","allDay":false}
]
}
}
分析代码如下：
复制代码 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。
