Question: what would be needed to apply the same thing on a normal button?

[AndroidDeveloperLB]

Suppose the current content of the layout is just:

-vertical linearLayout
-RecyclerView
-Button (at the bottom)

What would it need, to add a similar behavior of replacing the button at the bottom, with the SnackBar, as you did on the FAB ?
Or, even the more basic thing: to move the button to be above the SnackBar.
