androidx下报错 Failed resolution of: Landroid/view/View$OnUnhandledKeyEventListener_androidx.core.view.viewcompat$2

升级 AndroidStudio 以后，默认compileSdkVersion为30，APP运行后报这个错，但不闪退。

有两种解决办法：

方法一： 降低sdk版本号。

但只能修改到28，修改为27及以下会报错

AAPT: error: style attribute 'android:attr/dialogCornerRadius' not found.

方法二： 修改appcompat版本

implementation 'androidx.appcompat:appcompat:1.3.0-rc01'
