android - 不支持的操作异常 : Tried to obtain display from a Context not associated with one

Question

我在实时应用程序上遇到 UnsupportedOperationException 崩溃。所有崩溃都与 Moto Android 11 设备相关。可以看出它与onKeyUp有某种关系。但仍然不知道如何重现或解决此问题。
任何帮助，将不胜感激。

Fatal Exception: java.lang.UnsupportedOperationException: Tried to obtain display from a Context not associated with  one. Only visual Contexts (such as Activity or one created with Context#createWindowContext) or ones created with Context#createDisplayContext are associated with displays. Other types of Contexts are typically related to background entities and may return an arbitrary display.

所以我可以看到你可以在你的 Activity 中覆盖 onKeyUp 方法并且不返回 super.onKeyUp(...)调用。
