android中用jsonObject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 " );
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。
