It is possible that you have a different label than this: android.support.design.widget.CoordinatorLayout
maybe you have android.support.constraint.ConstraintLayout
.
If so, you should change it to android.support.design.widget.CoordinatorLayout , since the child elements can apply the attribute app:layout_behavior="@string/appbar_scrolling_view_behavior"
For Androidx I followed this and got problem solved.
summary: In Gradle:
implementation 'com.google.android.material:material:1.1.0-alpha05'
in XML:
app:layout_behavior="@string/appbar_scrolling_view_behavior"
If not solved then Invalidate caches / Restart
layout_behavior
attribute is part of the CoordinatorLayout
. It defines interaction behavior plugin for child views of CoordinatorLayout.
In your case you can either delete this attribute ( app:layout_behavior="@string/appbar_scrolling_view_behavior"
) from your code or wrap your RelativeLayout
with CoordinatorLayout
if you need behavior functionality.
