    } 
]

這是我的工作

嘗試{

 JSONArray jObject=new JSONArray(response); 

     for (int arr_size=0;arr_size<jObject.length();arr_size++){ 

      JSONObject dataObject= (JSONObject) jObject.get(arr_size); 

      System.out.println("dataObject: "+dataObject.toString()); 
      a_updated = dataObject.getString("a_updated"); 

     }

我想只存儲所有值

a_updated，A_ID，a_ref_annonceur，a_date_modified，a_time_modified，a_titre_1，a_titre_2

in arraylist

你get.you得到什麼響應。 – Yugesh

試試這個..

JSONArray jObject=new JSONArray(response); 

     for (int arr_size=0;arr_size<jObject.length();arr_size++){ 

      JSONObject dataObject= jObject.getJSONObject(arr_size); 

     if(dataObject.has("a_updated")) 
      System.out.println("a_updated: "+dataObject.getString("a_updated")); 
     if(dataObject.has("a_id")) 
      System.out.println("a_id: "+dataObject.getString("a_id")); 

      System.out.println("a_ref_annonceur: "+dataObject.getString("a_ref_annonceur")); 
      System.out.println("a_date_modified: "+dataObject.getString("a_date_modified")); 
      System.out.println("a_time_modified: "+dataObject.getString("a_time_modified")); 
      System.out.println("a_titre_1: "+dataObject.getString("a_titre_1")); 


     }

我沒有共享，但錯誤org.json.JSONException：沒有值爲a_updated – Dimitri

@Nikita檢查我的編輯**使用**有**是否存在或不 – Hariharan

@尼基塔，因爲第一部分**沒有** 'a_updated'所以只有 – Hariharan

，而不是JSONObject dataObject= (JSONObject) jObject.get(arr_size);

做JSONObject dataObject = jObject.getJSONObject(arr_size);

我確實改變了，但是org.json.JSONException：沒有值爲a_updated – Dimitri

試試這個...

ArrayList<String> arrayList = new ArrayList<String>(); 
    try { 
     JSONArray jsonArray = new JSONArray(response); 
     for(int i =0,N = jsonArray.length();i<N;i++) { 
      Object object = jsonArray.get(i); 
      if(object instanceof JSONObject) { 
       JSONObject jsonObject = (JSONObject) object; 
       Iterator iterator = jsonObject.keys(); 
       while(iterator.hasNext()) { 
        String text = (String) iterator.next(); 
        String string = jsonObject.getString(text); 
        arrayList.add(string); 
       } 
      } 
     } 
    } catch (Exception e) { 
     // TODO: handle exception 
    }

private ArrayList<String> list = new ArrayList<String> 

JSONArray jObject=new JSONArray(response); 

    for (int arr_size=0;arr_size<jObject.length();arr_size++){ 

     JSONObject dataObject= jObject.getJSONObject(arr_size); 
     list.add(dataObject.getString("a_updated")); 
     different_array_list.add(dataObject.getString("object name your give here")); 



    }

//數組列表對象 ArrayList中的ArrayList =新阿拉yList（）;我的回答是這樣的：JSONArray（jsonArray）= new JSONArray（your Response string）;這個JSONArray是一個json數組，

for (int i=1;i<jsonArray.length();i++){ 

     JSONObject dataObject= (JSONObject) jsonArray.get(i); 
          ;       
      arrList.add(dataObject.getString("a_updated"));  
      arrList.add(dataObject.getString("a_id"));  
      arrList.add(dataObject.getString("a_ref_annonceur"));  
      arrList.add(dataObject.getString("a_date_modified"));  
      arrList.add(dataObject.getString("a_time_modified")); 
      arrList.add(dataObject.getString("a_titre_1"));  
      arrList.add(dataObject.getString("a_titre_2"));  
    }

//打印數組列表，你會得到所有的數據
