ScrollerCompat

public void abortAnimation()

Stops the animation. Aborting the animation causes the scroller to move to the final x and y position.

public boolean computeScrollOffset()

Call this when you want to know the new location. If it returns true, the animation is not yet finished. loc will be altered to provide the new location.

public static ScrollerCompat create(Context context, Interpolator interpolator)

public void fling(
    int startX,
    int startY,
    int velocityX,
    int velocityY,
    int minX,
    int maxX,
    int minY,
    int maxY
)

Start scrolling based on a fling gesture. The distance travelled will depend on the initial velocity of the fling.

public void fling(
    int startX,
    int startY,
    int velocityX,
    int velocityY,
    int minX,
    int maxX,
    int minY,
    int maxY,
    int overX,
    int overY
)

Start scrolling based on a fling gesture. The distance travelled will depend on the initial velocity of the fling.

public float getCurrVelocity()

Returns the current velocity on platform versions that support it.

This method should only be used as input for nonessential visual effects such as EdgeEffectCompat.

public int getCurrX()

Returns the current X offset in the scroll.

public int getCurrY()

Returns the current Y offset in the scroll.

public int getFinalX()

public int getFinalY()

public boolean isFinished()

Returns whether the scroller has finished scrolling.

public boolean isOverScrolled()

Returns whether the current Scroller is currently returning to a valid position. Valid bounds were provided by the fling method. One should check this value before calling startScroll as the interpolation currently in progress to restore a valid position will then be stopped. The caller has to take into account the fact that the started scroll will start from an overscrolled position.

public void notifyHorizontalEdgeReached(int startX, int finalX, int overX)

Notify the scroller that we've reached a horizontal boundary. Normally the information to handle this will already be known when the animation is started, such as in a call to one of the fling functions. However there are cases where this cannot be known in advance. This function will transition the current motion and animate from startX to finalX as appropriate.

public void notifyVerticalEdgeReached(int startY, int finalY, int overY)

Notify the scroller that we've reached a vertical boundary. Normally the information to handle this will already be known when the animation is started, such as in a call to one of the fling functions. However there are cases where this cannot be known in advance. This function will animate a parabolic motion from startY to finalY.

public boolean springBack(int startX, int startY, int minX, int maxX, int minY, int maxY)

Call this when you want to 'spring back' into a valid coordinate range.

public void startScroll(int startX, int startY, int dx, int dy)

Start scrolling by providing a starting point and the distance to travel. The scroll will use the default value of 250 milliseconds for the duration.

public void startScroll(int startX, int startY, int dx, int dy, int duration)

Start scrolling by providing a starting point and the distance to travel.
