我正在尝试调用我的网络应用程序 API，它成功地为我获取了所有“配置文件”的列表并以正确的方式显示它们（配置文件的 JsonArrayRequest）。但是，我在调用一个连续的 url 时遇到问题，该 url 包含由配置文件 ID 指示的配置文件的“匹配项”。当我调用此 APi 并尝试在每个配置文件下方显示匹配量时，它可能工作了一半。我认为我的问题可能在于重用 requestQueue 但我已经尝试创建新的，但我的问题仍然存在！任何帮助，将不胜感激。

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

以下是对 Matchrequest API 的响应示例。

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

这是来自卖家资料 API 的回复

{"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"}

我想出了一个解决方法，但没有直接回答我的问题。我意识到我可以直接从配置文件 api 中提取并使用 JSON 数组的“matching_opportunities”部分，而不是费心调用 MATCH api。
