问题在于这两行：

    app:cardUseCompatPadding="true"
    card_view:cardUseCompatPadding="true"

删除 其中一个，它就会被修复。

解释：尽管这两行看起来不同，但实际上它们是相同的，因为如果你看这个：

xmlns:card_view="http://schemas.android.com/apk/res-auto"
xmlns:app="http://schemas.android.com/apk/res-auto"

这两个命名空间被声明为同一个，这实际上意味着这两个引用相同的东西，因此两次声明相同的属性会使其重复，这是不允许的。
