android解析json數據格式 – Android移動開發技術文章_手機開發 Android移動開發教學課程

json數據格式解析我自己分為兩種;

一種是普通的,一種是帶有數組形式的;

普通形式的:

服務器端返回的json數據格式如下:

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

分析代碼如下:

// TODO 狀態處理500 200

                int res = 0;

                res = httpClient.execute(httpPost).getStatusLine().getStatusCode();

                if (res == 200) {

                    /*

                     * 當返回碼為200時,做處理

                     * 得到服務器端返回json數據,並做處理

                     * */

                    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");

帶數組形式的:

服務器端返回的數據格式為:

{"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:

// TODO 狀態處理500 200

                int res = 0;

                res = httpClient.execute(httpPost).getStatusLine().getStatusCode();

                if (res == 200) {

                    /*

                     * 當返回碼為200時,做處理

                     * 得到服務器端返回json數據,並做處理

                     * */

                    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());

                    /**

                     * 這裡需要分析服務器回傳的json格式數據,

                     */

                    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);

                    }

總結,普通形式的隻需用JSONObject ,帶數組形式的需要使用JSONArray 將其變成一個list。
