JSONObject 解析json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:

{"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 = (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 (httpPost); 
          StringBuilder builder = new StringBuilder(); 
          BufferedReader bufferedReader2 = new BufferedReader( 
              new InputStreamReader(().getContent())); 
          String str2 = ""; 
          for (String s = bufferedReader2.readLine(); s != null; s = bufferedReader2 
              .readLine()) { 
            builder.append(s); 
          } 
          Log.i("cat", "$amp;>amp;>amp;>amp;>amp;>amp;>quot;$ + 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 = (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 (httpPost); 
          StringBuilder builder = new StringBuilder(); 
          BufferedReader bufferedReader2 = new BufferedReader( 
              new InputStreamReader(().getContent())); 
          String str2 = ""; 
          for (String s = bufferedReader2.readLine(); s != null; s = bufferedReader2 
              .readLine()) { 
            builder.append(s); 
          } 
          Log.i("cat", "$amp;>amp;>amp;>amp;>amp;>amp;>quot;$ + 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。
