This package is part of the Android support library which is no longer maintained. The support library has been superseded by AndroidX which is part of Jetpack.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.

Public methods

getDuration

added in version 22.1.0

int getDuration ()

Returns
int

getDx

added in version 22.1.0

int getDx ()

Returns
int

getDy

added in version 22.1.0

int getDy ()

Returns
int

getInterpolator

added in version 22.1.0

Interpolator getInterpolator ()

Returns
Interpolator

jumpTo

added in version 24.1.0

void jumpTo (int targetPosition)

Instead of specifying pixels to scroll, use the target position to jump using scrollToPosition(int).

You may prefer using this method if scroll target is really far away and you prefer to jump to a location and smooth scroll afterwards.

Note that calling this method takes priority over other update methods such as update(int, int, int, Interpolator), setX(float), setY(float) and #setInterpolator(Interpolator). If you call jumpTo(int), the other changes will not be considered for this animation frame.

Parameters
targetPosition	int: The target item position to scroll to using instant scrolling.

setDuration

added in version 22.1.0

void setDuration (int duration)

Parameters
duration	int

setDx

added in version 22.1.0

void setDx (int dx)

Parameters
dx	int

setDy

added in version 22.1.0

void setDy (int dy)

Parameters
dy	int

setInterpolator

added in version 22.1.0

void setInterpolator (Interpolator interpolator)

Sets the interpolator to calculate scroll steps

Parameters
interpolator	Interpolator: The interpolator to use. If you specify an interpolator, you must also set the duration.

• setDuration(int)

update

added in version 22.1.0

void update (int dx, 
                int dy, 
                int duration, 
                Interpolator interpolator)

Updates the action with given parameters.

Parameters
dx	int: Pixels to scroll horizontally
dy	int: Pixels to scroll vertically
duration	int: Duration of the animation in milliseconds
interpolator	Interpolator: Interpolator to be used when calculating scroll position in each animation step
