我该怎么办？

Answer 1

从LinearLayout属性中删除此行：

tools:context=".MainActivity"

您不需要传递上下文。它已经获得了上下文，您正在尝试再次传递它。因此属性重复。

另外，删除正在使用的xmlns属性。它也会导致错误。删除这些行：

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

xmlns:android="http://schemas.android.com/apk/res/android"
