  • android解析JSON数据

    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");

    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); 
                        }
