我使用 infinteScrollAdapter 和来自 json 的 connectionRequest 来填充组件，但有时它会给出以下错误，而它通常运行良好。这里可能有什么问题？如果我再次运行，它工作正常，但有时会挂起相当长的时间，然后显示此错误

最佳答案
那里有很多代码，但不是全部，所以我无法对此发表评论。我确实注意到你每次都关闭网络，这是错误的。您应该只在非常极端的情况下调用关闭。
此异常报告我们的事件队列已完全满。这是一种疯狂的情况，只有在 EDT 保持到位时 native 代码不断发送事件才能达到这种情况。在模拟器中打开 EDT 违规检测工具，它可能会指出实际的违规情况。
要了解有关 EDT 的更多信息，请查看 developer guide .
关于java - EDT 性能非常慢，显示触发错误，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/35288964/
