不通過排序在android中檢索mysql的所有數據

您好我想從mysql中檢索所有數據並通過排列和php顯示在android的listview中但我只收到一個響應對象中的記錄並在列表視圖中只顯示一條記錄我不知道錯誤在哪裏。我的Android代碼是不通過排序在android中檢索mysql的所有數據

JsonArrayRequest jsonArrayRequest=new JsonArrayRequest(url, new Response.Listener<JSONArray>() { 
      @Override 
      public void onResponse(JSONArray response) { 
      hide(); 


       ////////get json data 
       for(int i=0; i<response.length(); i++){ 

        try { 
         Log.d("the ","response "+response); 
         JSONObject obj=response.getJSONObject(i); 
         item item=new item(); 
         item.setTitlwimage(obj.getString("Title_Image")); 
         item.setTitle(obj.getString("Vedio_Title")); 
         item.setDescription(obj.getString("Description")); 
         item.setCate(obj.getInt("S_category_Id")); 
         // item.setTime(obj.getDouble("Datetime")); 

        list.add(item); 

        } 
        catch (JSONException e) { 
         e.printStackTrace(); 
         Log.d("Error"," and "+String.valueOf(response)); 
       } 
       } 
       adapter.notifyDataSetChanged(); 
      } 
     }, new Response.ErrorListener() { 
      @Override 
      public void onErrorResponse(VolleyError error) { 
        error.printStackTrace(); 
      } 
     }); 


     Singleton.getinstance().addtorequest(jsonArrayRequest); 


     //System.out.println("vvvvvvvvvvvvvvvvvv"+t.getText()); 
    }

和JSON甲是

和PHP代碼是

<?php 

include('Connection.php'); 
$sql = "select * from vedio"; 
    $result = mysqli_query($con,$sql); 
     $response=array(); 
     if(mysqli_num_rows($result)>0){ 
     while($row=mysqli_fetch_assoc($result)){ 
      $response[]=$row;  
      echo json_encode($response); 
     } 

} 
else{ 

echo mysqli_error($con); 
} 
?>

和響應的對象僅檢索

[{"Description":"2011 commercial by MOE (Ministry of `Education","Title_Image":"http:\/\/192.168.43.2\/Library\/pimages\/asd.jpg","Link":"https:\/\/www.youtube.com\/watch?v=UIun5xGK86g","Vedio_Title":"A touching commercial that rubs the deepest p","S_category_Id":"1","Vedio_Id":"16","Datetime":"2017-08-09 17:38:36"}]`

你是在每次讀取下一行時寫入數組。試試這個：

while($row=mysqli_fetch_assoc($result)) 
{ 
    array_push( $response,$row);      
} 
    echo json_encode($response);

AFAIK在陣列'$響應使用空索引[] = ...'不會覆蓋它，它會增加元件到它 – Yazan

@Yazan只需將json_encode（$響應）總分while循環。 – deejay

@deejay是的，這是在我的答案:) – Yazan

只是把echo json_encode($response);跳出while循環的，因爲你打印第一循環的反應，這就是服務器發回給你發送請求。

while($row=mysqli_fetch_assoc($result)){ 
    $response[]=$row;  
} 
echo json_encode($response);

編碼並在循環完成所有迭代時發送響應。
