No resource identifier found for attribute 'layout_behavior' in package

Question

My application worked fine until I tried to add a library to it. After I added the library, Android Studio gives me the following error:

Error:(26) No

Answer 1

For those who use AndroidX and don't want to add the old library:

com.android.support:design:28.0.0

you can add instead:

implementation 'com.google.android.material:material:1.0.0'

and use it like this:

app:layout_behavior="com.google.android.material.appbar.AppBarLayout$ScrollingViewBehavior"
