Override this method if you wish to adjust the anchor coordinates for each child view
during a layout pass. In the override set the new desired anchor coordinates in
the provided array. The coordinates should be provided in relation to the child view.
Parameters
child
View: The child view to which the anchor coordinates will apply.
anchorOffsetXY
float: The anchor coordinates for the provided child view, by default set
to a pre-defined constant on the horizontal axis and half of the
child height on the vertical axis (vertical center).
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.
