Android App鼠标指针输入在Activity UI元素上无法正常工作

问题描述

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

我正在开发可在手机，标签和电视盒上使用的Android应用。我的应用程序需要处理来自触摸，鼠标指针或遥控器的输入。

当前，“我的代码”可以很好地实现该功能，但是鼠标输入的处理中存在异常行为，仅在电视盒上发生。

问题：应用启动后，遥控器可以轻松导航到focusable元素上但是应用程序元素不会检测到指针上的鼠标。现在，将鼠标指针移至“音量选项”，然后单击以返回。该应用程序开始检测鼠标，但是经过一些操作后，它再次从应用程序UI中松开focus并移动了鼠标指针，并再次检测不到点击。

请观看下面的链接视频，以了解应用程序当前的运行方式。 https://jumpshare.com/v/bvyfbqZFWNJfoUsXJbSU

问题要点：当音量控制器显示在应用程序上方时，鼠标可以在音量跟踪器上进行更改，并在单击鼠标左键后出来。该应用程序会响应悬停和鼠标指针操作，并且在该应用程序上执行某些操作后，它将再次变得无响应。

应用程序应遵循的一些条件：

解决方法

从我的MainActivity中删除了`getSupportActionBar().hide();`后，我解决了这个奇怪的问题。
解决方案说明：我发现当未从主题中删除应用栏时，该应用上的鼠标事件开始起作用。

我为用例隐藏了干净的UI的应用程序栏，但这只是一项增强，因此请取消隐藏应用程序栏以使其正常工作。如果您坚持使用相同的独特案例，希望对您有所帮助。
