我們如何使用java代碼在屏幕上打印這個JSON數據？

-2

我要打印數組列表使用Java代碼..... 我必須表現出每個學生出勤我們如何使用java代碼在屏幕上打印這個JSON數據？

ArrayList的text_view_list =新的ArrayList（）;

 JSONObject jsonObject=new JSONObject(response_view); 


     for(int x=0;x<jsonObject.length();x++) { 

      Iterator<String> iterator = jsonObject.keys(); 
      while (iterator.hasNext()) { 
       String key = iterator.next(); 

       student_name=key.replaceAll("[0-9-_]"," "); 

       header[x]+=student_name; 
       JSONArray jsonArray = jsonObject.getJSONArray(key); 

       for (int i = 0; i < jsonArray.length(); i++) { 
        jsonObject2 = jsonArray.getJSONObject(i); 

        text_view_list.add(new ViewAttendanceData(jsonObject2.getString("status"), jsonObject2.getString("date"))); 

       } 
      } 
     }

頭是字符串數組用來存儲學生姓名後更換號碼This Type of data Which i want to Show in Screen。

代碼顯示的數據有些事情是這樣的：

TableLayout STK =（TableLayout）rootView.findViewById（R.id.id_table_V_Atte）;

  for (int i=0;i<header.length;i++){ 
       TableRow tableRow=new TableRow(context); 
       TextView tv0 = new TextView(context); 
       for(int j=0;j<1;j++){ 
        tv0.setText(""); //Dont Know What we have to write 

        tv0.setPadding(5, 10, 10, 10); 

        tv0.setGravity(Gravity.CENTER); 
        tv0.setTextColor(Color.GREEN); 
        tableRow.addView(tv0); 
        break; 

       }stk.addView(tableRow); 
      } 




My JSON is

       "Mr. VICKRAM SINGH_269": [

顯然你的反應是不是JSON數組 – Selvin

我的回答是存放在字符串變量名稱response_view –

JSONObject jsonArray1=new JSONObject(response_view); //Getting Response from server 

         for(int x=0;x<jsonArray1.length();x++) { 
          JSONArray jsonArray = jsonArray1.getJSONArray(x); 
          for (int i = 0; i < jsonArray.length(); i++) { 
           jsonObject = jsonArray.getJSONObject(i); 
           text_view_list.add(new ViewAttendanceData(jsonObject.getString("status"), jsonObject.getString("date"))); 
          } 

         }

試試這個希望有幫助，你的JSON響應不正確

我的回答是存儲在字符串變量名稱作爲response_view –

我得到一個錯誤再次 –

我知道這一點。所以你的迴應首先有JSONObject並且你檢索JSONArray。發佈錯誤日誌 –

The keys of the JsonObject are dynamic. So we can parse the data as the help of below methods. 

private void parseData(String result) { 
    try { 
     if (result != null) { 
      JSONObject data = new JSONObject(result); 
      if(data != null) {} 
       Iterator<String> it = data.keys(); 
       while (it.hasNext()) { 
        String key = it.next(); 
        try { 
         System.out.println("Data of: " + key); 
         if (data.get(key) instanceof JSONArray) { 
          JSONArray arry = data.getJSONArray(key); 
          int size = arry.length(); 
          for (int i = 0; i < size; i++) { 
           parseJson(arry.getJSONObject(i)); 
          } 
         } else if (data.get(key) instanceof JSONObject) { 
          parseJson(data.getJSONObject(key)); 
         } 
        } catch (Throwable e) { 
         try { 
          System.out.println(key + ":" + data.getString(key)); 
         } catch (Exception ee) { 
         } 
         e.printStackTrace(); 

        } 
       } 
      } 
     } 
    } catch (Exception e){} 
} 

private void parseJson(JSONObject object) { 
    try { 
     if(object != null) { 
      System.out.println("Status:" + data.getString("status") + ", date:" + data.getString("date")); 
     } 
    } catch (Exception e) {} 
}
