Kotlin Android 扩展和 AndroidX 似乎没有正确投射视图
Kotlin Android Extensions and AndroidX seem not casting correctly Views
当我尝试将 AndroidX 用于我的 Android/Kotlin 项目时,KAE 恢复的许多视图在我的代码中失败(类型不匹配),因为它们都是用 View!
类型定义的。
例如,这里:
或此处:
发生什么事了?
这是我的工具栏所在的布局:

我找到了编辑布局文件的解决方案。
使用 com.google.android.material.appbar.AppBarLayout
而不是 android.support.design.widget.AppBarLayout
。或者使用 androidx.appcompat.widget.Toolbar
而不是 android.support.v7.widget.Toolbar
.
不幸的是,您必须手动完成所有操作...
