ScrollerCompat

public final class ScrollerCompat
extends Object

java.lang.Object
↳	android.support.v4.widget.ScrollerCompat

This class was deprecated in API level 26.1.0.
Use OverScroller directly.

Provides access to new Scroller APIs when available.

This class provides a platform version-independent mechanism for obeying the current device's preferred scroll physics and fling behavior. It offers a subset of the APIs from Scroller or OverScroller.

Public methods

abortAnimation

added in version 22.1.0

void abortAnimation ()

This method was deprecated in API level 26.1.0.
Use abortAnimation() directly.

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

computeScrollOffset

added in version 22.1.0

boolean computeScrollOffset ()

This method was deprecated in API level 26.1.0.
Use computeScrollOffset() directly.

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.

Returns
`boolean`

create

added in version 22.1.0

`minX`	`int`: Minimum X value. The scroller will not scroll past this point.
`maxX`	`int`: Maximum X value. The scroller will not scroll past this point.
`minY`	`int`: Minimum Y value. The scroller will not scroll past this point.
`maxY`	`int`: Maximum Y value. The scroller will not scroll past this point.

`maxX`	`int`: Maximum X value. The scroller will not scroll past this point.
`minY`	`int`: Minimum Y value. The scroller will not scroll past this point.
`maxY`	`int`: Maximum Y value. The scroller will not scroll past this point.
`overX`	`int`: Overfling range. If > 0, horizontal overfling in either direction will be possible.

getCurrVelocity

added in version 22.1.0

float getCurrVelocity ()

This method was deprecated in API level 26.1.0.
Use getCurrVelocity() directly.

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.

Returns
`float`	The original velocity less the deceleration. Result may be negative.

getCurrX

added in version 22.1.0

int getCurrX ()

This method was deprecated in API level 26.1.0.
Use getCurrX() directly.

Returns the current X offset in the scroll.

Returns
`int`	The new X offset as an absolute distance from the origin.

getCurrY

added in version 22.1.0

int getCurrY ()

This method was deprecated in API level 26.1.0.
Use getCurrY() directly.

Returns the current Y offset in the scroll.

Returns
`int`	The new Y offset as an absolute distance from the origin.

getFinalX

added in version 22.1.0

int getFinalX ()

This method was deprecated in API level 26.1.0.
Use getFinalX() directly.

Returns
`int`	The final X position for the scroll in progress, if known.

getFinalY

added in version 22.1.0

int getFinalY ()

This method was deprecated in API level 26.1.0.
Use getFinalY() directly.

Returns
`int`	The final Y position for the scroll in progress, if known.

isFinished

added in version 22.1.0

boolean isFinished ()

This method was deprecated in API level 26.1.0.
Use isFinished() directly.

Returns whether the scroller has finished scrolling.

Returns
`boolean`	True if the scroller has finished scrolling, false otherwise.

isOverScrolled

added in version 22.1.0

boolean isOverScrolled ()

This method was deprecated in API level 26.1.0.
Use isOverScrolled() directly.

Returns whether the current Scroller is currently returning to a valid position. Valid bounds were provided by the fling(int, int, int, int, int, int, int, int, int, int) method. One should check this value before calling startScroll(int, int, int, int) 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.

Returns
`boolean`	true when the current position is overscrolled and in the process of interpolating back to a valid value.

notifyHorizontalEdgeReached

added in version 22.1.0

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

This method was deprecated in API level 26.1.0.
Use notifyHorizontalEdgeReached(int, int, int) directly.

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.

Parameters
`startX`	`int`: Starting/current X position
`finalX`	`int`: Desired final X position
`overX`	`int`: Magnitude of overscroll allowed. This should be the maximum desired distance from finalX. Absolute value - must be positive.

notifyVerticalEdgeReached

added in version 22.1.0

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

This method was deprecated in API level 26.1.0.
Use notifyVerticalEdgeReached(int, int, int) directly.

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.

Parameters
`startY`	`int`: Starting/current Y position
`finalY`	`int`: Desired final Y position
`overY`	`int`: Magnitude of overscroll allowed. This should be the maximum desired distance from finalY. Absolute value - must be positive.

springBack

added in version 24.1.0

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

This method was deprecated in API level 26.1.0.
Use springBack(int, int, int, int, int, int) directly.

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

Parameters
`startX`
