android中解析后台返回的json字符串

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}}

// TODO 状态处理 500 200
int res = ;
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 = ;
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=;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。
