Override this method to implement custom child layout behavior on scroll. It is called
at the end of each layout pass of the view (including scrolling) and enables you to
modify any property of the child view. Examples include scaling the children based on
their distance from the center of the parent, or changing the translation of the children
to create an illusion of the path they are moving along.
Parameters
child
View: the current child to be affected.
parent
RecyclerView: the RecyclerView parent that this class is attached to.
