Public functions
Float

Returns the current bezel width for circular scrolling as a fraction of the screen's radius.
Float

Returns how many degrees does the user have to rotate for to scroll through one screen height.
Boolean

Returns whether circular scrolling is enabled for this view.
Boolean

Returns whether the view is currently configured to center the edge children.
Boolean
Unit

Taps within this radius and the radius of the screen are considered close enough to the bezel to be candidates for circular scrolling.
Unit
setCircularScrollingGestureEnabled(
    circularScrollingGestureEnabled: Boolean
)

Enables/disables circular touch scrolling for this view.
Unit

Use this method to configure the WearableRecyclerView on round watches to always align the first and last items with the vertical center of the screen.
Unit
setScrollDegreesPerScreen(degreesPerScreen: Float)

Sets how many degrees the user has to rotate by to scroll through one screen height when they are using the circular scrolling gesture.The default value equates 180 degrees scroll to one screen.

Public functions

getBezelFraction

Added in 1.1.0
fun getBezelFraction(): Float

Returns the current bezel width for circular scrolling as a fraction of the screen's radius.

See also
setBezelFraction

getScrollDegreesPerScreen

Added in 1.1.0
fun getScrollDegreesPerScreen(): Float

Returns how many degrees does the user have to rotate for to scroll through one screen height.

setCircularScrollingGestureEnabled
setScrollDegreesPerScreen

isCircularScrollingGestureEnabled

Added in 1.1.0
fun isCircularScrollingGestureEnabled(): Boolean

Returns whether circular scrolling is enabled for this view.

See also
setCircularScrollingGestureEnabled

isEdgeItemsCenteringEnabled

Added in 1.1.0
fun isEdgeItemsCenteringEnabled(): Boolean

Returns whether the view is currently configured to center the edge children. See setEdgeItemsCenteringEnabled for details.

onTouchEvent

fun onTouchEvent(event: MotionEvent!): Boolean

setBezelFraction

Added in 1.1.0
fun setBezelFraction(fraction: Float): Unit

Taps within this radius and the radius of the screen are considered close enough to the bezel to be candidates for circular scrolling. Expressed as a fraction of the screen's radius. The default is the whole screen i.e 1.0f.

setCircularScrollingGestureEnabled

Added in 1.1.0
fun setCircularScrollingGestureEnabled(
    circularScrollingGestureEnabled: Boolean
): Unit

Enables/disables circular touch scrolling for this view. When enabled, circular touch gestures around the edge of the screen will cause the view to scroll up or down. Related methods let you specify the characteristics of the scrolling, like the speed of the scroll or the are considered for the start of this scrolling gesture.

setScrollDegreesPerScreen
setBezelFraction

setEdgeItemsCenteringEnabled

Added in 1.1.0
fun setEdgeItemsCenteringEnabled(isEnabled: Boolean): Unit

Use this method to configure the WearableRecyclerView on round watches to always align the first and last items with the vertical center of the screen. This effectively moves the start and end of the list to the middle of the screen if the user has scrolled so far. It takes the height of the children into account so that they are correctly centered. On nonRound watches, this method has no effect and original padding is used.

Parameters
isEnabled: Boolean

set to true if you wish to align the edge children (first and last) with the center of the screen.

setScrollDegreesPerScreen

Added in 1.1.0
fun setScrollDegreesPerScreen(degreesPerScreen: Float): Unit

Sets how many degrees the user has to rotate by to scroll through one screen height when they are using the circular scrolling gesture.The default value equates 180 degrees scroll to one screen.

Parameters
degreesPerScreen: Float

the number of degrees to rotate by to scroll through one whole height of the screen,
