解决了！https://stackoverflow.com/a/63790855/12021422

我正在开发一个适用于手机、标签和电视盒的 Android 应用程序。我的应用程序需要处理来自触摸、鼠标指针或远程的输入。

目前，我的代码可以很好地实现该功能，但处理鼠标输入的异常行为仅发生在电视盒上。

问题：当应用程序启动时，遥控器可以轻松地在focusable元素上导航，但鼠标指针不会被应用程序元素检测到。现在，当鼠标指针移至音量选项，然后单击返回时。该应用程序开始检测鼠标，但经过一些操作后，它再次focus从应用程序 UI 中丢失，鼠标指针的运动和点击再次变得未被检测到。

请观看下面链接中的视频，了解应用程序当前的行为方式。 https://jumpshare.com/v/bvyfbqZFWNJfoUsXJbSU

问题要点：由于音量控制器显示在应用程序上方，鼠标可以在音量跟踪器上进行更改，并在左键单击后出来。该应用程序会响应悬停和鼠标指针操作，并且当在应用程序上执行某些操作时，它会再次变得无响应。

应用程序应遵循的一些条件：

  • 最低 SDK 19
  • 滚动视图

getSupportActionBar().hide();从我的 MainActivity中删除 get 后，我​​解决了这个奇怪的问题。

解决方案描述：我发现当应用程序栏没有从主题中删除时，应用程序上的鼠标事件开始工作。

我正在为我的用例隐藏应用栏以获得干净的 UI，但这只是一种增强功能，因此取消隐藏应用栏以使其工作。如果您遇到相同的独特案例，我希望这会有所帮助。
