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

if you not added android material yet first add this line in your dependencies in build.gradle file

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

then use this attribute instead

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