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");
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 = 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); 
                    }

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。
