Floating action button not visible on scrolling after updating Google Support & Design Library

Question

I\'ve tried updating com.android.support:appcompat and com.android.support:design from: 25.0.1 to 25.1.0, as follows:

compile \'com         


        

Answer 1

The behavior has changed since support lib version 25.1.0.

It must be the RecyclerView (Behavior) that triggers the FAB visibility change.

In other words, it's no longer the responsibility of the object that wants to react to have a behavior but on the object that moves to be aware of everything on screen.

Below is a link to a diff that shows the changes that are required to perform the upgrade:
