这里有什么问题？我试着按照医生说的去做，有什么帮助吗？

Answer 1

您必须将tools属性绑定到清单元素：

<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="[YOUR APP NAME]" xmlns:tools="http://schemas.android.com/tools" >

Answer 2

我刚刚解决了它！您需要将这一行添加到manifest标记中——它实际上是文件中的第一个标记：xmlns:tools="http://schemas.android.com/tools"
