DefaultOffsettingHelper
extends WearableRecyclerView.OffsettingHelper
This class is deprecated.
use the androidx.wear.widget.WearableRecyclerView and associated classes
provided by the Jetpack Wear library
instead.
This implementation of WearableRecyclerView.OffsettingHelper provides basic offsetting
logic for updating child layout. For round devices it offsets the children horizontally to make
them appear to travel around a circle. For square devices it aligns them in a straight list.

Public methods
adjustAnchorOffsetXY
public void adjustAnchorOffsetXY (View child,
float[] anchorOffsetXY)
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).
|
updateChild
public void updateChild (View child,
WearableRecyclerView parent)
The default implementation will lay out children along a curve for round screens and along a
straight line for square screens.
| Parameters |
|---|
child |
View: the current child to be affected. |
parent |
WearableRecyclerView: the WearableRecyclerView parent that this helper is attached to.
