Answer 1

You need to do the same thing which happens with fab, first create a class extending CoordinatorLayout.Behavior<View> and implement it like other fab examples. just remember that it won't work on simple listView and gridView. Also here 'sa good detailed tutorial for you.

Answer 2

You Just have to set Scroll-Up & Scroll-Down listener of your Recycler view or Scroll View check Reference link .

Now base on Scroll-Up & Scroll-Down listener set VISIBLE / GONE of your footer view either it is LinearLayout or Toolbar with animation.
