WearableRecyclerView

This package is part of the Android support library which is no longer maintained. The support library has been superseded by AndroidX which is part of Jetpack. We recommend using the AndroidX libraries in all new projects. You should also consider migrating existing projects to AndroidX. To find the AndroidX class that maps to this deprecated class, see the AndroidX support library class mappings.

Public methods

getBezelFraction

added in version 26.1.0

float getBezelFraction ()

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

Returns
float

See also:

• setBezelFraction(float)

getScrollDegreesPerScreen

added in version 26.1.0

float getScrollDegreesPerScreen ()

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

Returns
float

See also:

• setCircularScrollingGestureEnabled(boolean)
• setScrollDegreesPerScreen(float)

isCircularScrollingGestureEnabled

added in version 26.1.0

boolean isCircularScrollingGestureEnabled ()

Returns whether circular scrolling is enabled for this view.

Returns
boolean

See also:

• setCircularScrollingGestureEnabled(boolean)

isEdgeItemsCenteringEnabled

added in version 26.1.0

boolean isEdgeItemsCenteringEnabled ()

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

Returns
boolean

onTouchEvent

boolean onTouchEvent (MotionEvent event)

Parameters
event	MotionEvent

Returns
boolean

setBezelFraction

added in version 26.1.0

void setBezelFraction (float fraction)

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.

Parameters
fraction	float

setCircularScrollingGestureEnabled

added in version 26.1.0

void setCircularScrollingGestureEnabled (boolean circularScrollingGestureEnabled)

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.

Parameters
circularScrollingGestureEnabled	boolean

See also:

• setScrollDegreesPerScreen(float)
• setBezelFraction(float)

setEdgeItemsCenteringEnabled

added in version 26.1.0

void setEdgeItemsCenteringEnabled (boolean isEnabled)

Use this method to configure the WearableRecyclerView 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.

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 version 26.1.0

void setScrollDegreesPerScreen (float degreesPerScreen)

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,
