Public methods
getDuration
int getDuration ()
jumpTo
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
void setDuration (int duration)
setDx
void setDx (int dx)
setDy
void setDy (int dy)
setInterpolator
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. |
update
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
