android 解析json数据格式的方法

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：

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

分析代码如下：

代码如下:
// TODO 状态处理 500 200
                int res = 0;
                res = HttpClient.execute(httpPost).getStatusLine().getStatusCode();
                if (res == 200) {
                   
                    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：

代码如下:
{"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}
            ]
    }
}

分析代码如下：

代码如下:
// TODO 状态处理 500 200
                int res = 0;
                res = httpClient.execute(httpPost).getStatusLine().getStatusCode();
                if (res == 200) {
                   
                    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("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。
