Android 应用程序鼠标指针输入在 Activity UI 元素上工作不正常
Android App Mouse Pointer Input Not working well on Activity UI Elements
已解决!
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控、鼠标指针或遥控器的输入。
目前,我的代码可以很好地实现功能,但在鼠标输入处理中存在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
但是指针处的鼠标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,它再次从应用程序 UI 中松开 focus
,并且鼠标指针的移动和点击再次变得检测不到。
请观看下面 Link 中的视频,了解该应用程序当前的运行情况。

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现。该应用程序会响应悬停和鼠标指针操作,当对应用程序进行某些操作时,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
代码
