Answer 1

更新到最新的 Android Studio 并重新导入项目解决了我的问题。

Answer 2

为了解决这个问题，我必须更新布局文件上的所有类名。

从：

<android.support.design.widget.CoordinatorLayout
<android.support.v7.widget.RecyclerView
...

自：

<androidx.core.widget.NestedScrollView
<androidx.coordinatorlayout.widget.CoordinatorLayout
...

之后，数据绑定错误消失了。

我运行了迁移工具，但它没有修复布局 xml 上的类名，可悲！
