json數(shù)據(jù)格式解析我自己分為兩種；

一種是普通的，一種是帶有數(shù)組形式的；

普通形式的：
服務(wù)器端返回的json數(shù)據(jù)格式如下：

{"userbean":{"Uid":"100196","Showname":"/u75af/u72c2/u7684/u7334/u5b50","Avtar":null,"State":1}}

分析代碼如下：

復(fù)制代碼代碼如下:

// TODO 狀態(tài)處理 500 200
                int res = 0;
                res = httpClient.execute(httpPost).getStatusLine().getStatusCode();
                if (res == 200) {
                    /*
                     * 當(dāng)返回碼為200時，做處理
                     * 得到服務(wù)器端返回json數(shù)據(jù)，并做處理
                     * */
                    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(shù)組形式的：
服務(wù)器端返回的數(shù)據(jù)格式為：

復(fù)制代碼代碼如下:

{"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：

復(fù)制代碼代碼如下:

// TODO 狀態(tài)處理 500 200 
                int res = 0; 
                res = httpClient.execute(httpPost).getStatusLine().getStatusCode(); 
                if (res == 200) { 
                    /* 
                     * 當(dāng)返回碼為200時，做處理 
                     * 得到服務(wù)器端返回json數(shù)據(jù)，并做處理 
                     * */ 
                    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()); 
                    /** 
                     * 這里需要分析服務(wù)器回傳的json格式數(shù)據(jù)， 
                     */ 
                    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); 
                    }
