【问题描述】：
我对 android TV 应用程序上的 Leanback ListRowPresenter 有疑问。
有时向左或向右滚动时，应用程序崩溃了。
我搜索了一些解决方案，但找到了答案“由 main(ui) 线程上的工作引起”，但我的项目在子线程和 UI 上工作的任务最少。
发生崩溃时我的Logcat：

Reason: Input dispatching timed out (Waiting to send key event because the focused window has not finished processing all of the input events that were previously delivered to it. Outbound queue length: 0. Wait queue length: 1.)
