android 解析json数据格式

前面我有用到android发送json数据；这里我想总结一下我用到的解析json数据格式的方式

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。
