Android Volley JsonArrayRequest工作時間的一半

Question

我正在嘗試調用我的web應用程序API，它成功地獲取了所有「配置文件」的列表，並以正確的方式顯示它們（用於配置文件的JsonArrayRequest）。但是，我遇到了問題，我正在調用連續的url，該URL包含配置文件ID指示的配置文件的「匹配」。當我打電話給這個APi並試圖在每個配置文件下面顯示匹配數量時，它可能工作一半時間。我認爲我的問題可能是重用requestQueue，但我嘗試了創建新的並且我的問題仍然存在！任何幫助，將不勝感激。

     Network network = new BasicNetwork(new HurlStack()); 
     mRequestQueue = new RequestQueue(cache, network); 
     mRequestQueue.start();

     JsonArrayRequest matchRequest = new JsonArrayRequest(matchCountUrl,

             buyersProfiles.get(k).setMatchCount(obj.getString("count")); 
             System.out.println(obj.getString("count")); 
            } 
           }

     }); 

     mRequestQueue.add(matchRequest); 
     mRequestQueue.add(profileRequest); 
     return root; 
    } 
} 

這裏是對Matchrequest API的響應示例。

[{"id":1,"count":"1"}] 

這裏是從賣家響應曲線API

{"id":1,"title":"Test Seller","profile_status":"ACTIVE","description":"Testing Seller Profile","locations":"Mid-Wilshire","asset_type":"RETAIL","property_status":"COMING_SOON","role":"PRINCIPAL","investment_lower":"650000","investment_upper":"900000","seller_id":2,"created_on":"2016-06-14T18:09:27.411Z","updated_on":"2016-06-14T18:09:27.411Z","matching_opportunities":"1"} 

Answer 1

我想出了一個解決方法，但沒有直接回答我的問題。與其不費力地調用MATCH api，我意識到我可以直接從配置文件API中取出並使用JSON數組的「matching_opportunities」部分。
