您能详细说明一下这句话吗，“但是对用户、页面或应用FQL表进行嵌套查询总是排在最后，因此不会显示在ListView中。”从代码上看，它类似于初始posts/stream查询完成回调，然后调用用户/page/app请求。这不是你想要的吗？我想你这里的问题是，以前所有的请求都是同步发出的（在发出进一步的请求之前，你一直在等待返回结果），而在新的实现中，你是异步发出请求的，这就是为什么你没有像以前那样看到结果的原因。@CAbernathy:很抱歉回复得太晚了。实际上，在我之前的实现中，我首先查询FQL流，获取
author\u id
，然后立即使用它查询名称和配置文件图片。这一过程同时发生。现在，它首先获取steam结果，然后查询用户、页面或应用程序FQL表。我暂时转向使用GraphAPI的“me/home”端点，但我更愿意使用FQL。我怎样才能让它像以前一样工作？查询同步运行，而不是像现在这样一个接一个地运行？
