json数据解析
Json数据解析可以分为两种
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。
