Public functions

adjustAnchorOffsetXY

Added in 1.1.0
fun adjustAnchorOffsetXY(child: View!, anchorOffsetXY: FloatArray!): Unit

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: FloatArray!

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).

onLayoutFinished

Added in 1.4.0-alpha01
fun onLayoutFinished(child: View!, parent: RecyclerView!): Unit

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.
