Added in 1.1.0

Kotlin |Java

class NestedScrollView : FrameLayout, NestedScrollingParent3, NestedScrollingChild3, ScrollingView

kotlin.Any
↳	android.view.View
	↳	android.view.ViewGroup
		↳	android.widget.FrameLayout
			↳	androidx.core.widget.NestedScrollView

NestedScrollView is just like ScrollView, but it supports acting as both a nested scrolling parent and child on both new and old versions of Android. Nested scrolling is enabled by default.

    type: Int
): Boolean

Dispatch one step of a nested scroll in progress before this view consumes any portion of it.

Nested pre-scroll events are to nested scroll events what touch intercept is to touch. dispatchNestedPreScroll offers an opportunity for the parent view in a nested scrolling operation to consume some or all of the scroll operation before the child view consumes it.

Parameters
`dx: Int`	Horizontal scroll distance in pixels
`dy: Int`	Vertical scroll distance in pixels
`consumed: IntArray?`	Output. If not null, consumed[0] will contain the consumed component of dx and consumed[1] the consumed dy.
`offsetInWindow: IntArray?`	Optional. If not null, on return this will contain the offset in local view coordinates of this view from before this operation to after it completes. View implementations may use this to adjust expected input coordinate tracking.
`type: Int`	the type of input which cause this scroll event

Returns
`Boolean`	true if the parent consumed some or all of the scroll delta

Dispatch one step of a nested scroll in progress.

Implementations of views that support nested scrolling should call this to report info about a scroll in progress to the current nested scrolling parent. If a nested scroll is not currently in progress or nested scrolling is not enabled for this view this method does nothing.

Compatible View implementations should also call dispatchNestedPreScroll before consuming a component of the scroll event themselves.

Parameters
`dxConsumed: Int`	Horizontal distance in pixels consumed by this view during this scroll step
`dyConsumed: Int`	Vertical distance in pixels consumed by this view during this scroll step
`dxUnconsumed: Int`	Horizontal scroll distance in pixels not consumed by this view
`dyUnconsumed: Int`	Horizontal scroll distance in pixels not consumed by this view
`offsetInWindow: IntArray?`	Optional. If not null, on return this will contain the offset in local view coordinates of this view from before this operation to after it completes. View implementations may use this to adjust expected input coordinate tracking.
`type: Int`	the type of input which cause this scroll event

Returns
`Boolean`	true if the event was dispatched, false if it could not be dispatched.

fun onNestedPreScroll(
    target: View,
    dx: Int,
    dy: Int,
    consumed: IntArray,
    type: Int
): Unit

React to a nested scroll in progress before the target view consumes a portion of the scroll.

When working with nested scrolling often the parent view may want an opportunity to consume the scroll before the nested scrolling child does. An example of this is a drawer that contains a scrollable list. The user will want to be able to scroll the list fully into view before the list itself begins scrolling.

onNestedPreScroll is called when a nested scrolling child invokes dispatchNestedPreScroll. The implementation should report how any pixels of the scroll reported by dx, dy were consumed in the consumed array. Index 0 corresponds to dx and index 1 corresponds to dy. This parameter will never be null. Initial values for consumed[0] and consumed[1] will always be 0.

Parameters
`target: View`	View that initiated the nested scroll
`dx: Int`	Horizontal scroll distance in pixels
`dy: Int`	Vertical scroll distance in pixels
`consumed: IntArray`	Output. The horizontal and vertical scroll distance consumed by this parent
`type: Int`	the type of input which cause this scroll event

onNestedScroll

onNestedScroll

Added in 1.16.0-alpha01

fun onNestedScroll(
    target: View,
    dxConsumed: Int,
    dyConsumed: Int,
    dxUnconsumed: Int,
    dyUnconsumed: Int,
    type: Int
): Unit

React to a nested scroll in progress.

This method will be called when the ViewParent's current nested scrolling child view dispatches a nested scroll event. To receive calls to this method the ViewParent must have previously returned true for a call to onStartNestedScroll.

Both the consumed and unconsumed portions of the scroll distance are reported to the ViewParent. An implementation may choose to use the consumed portion to match or chase scroll position of multiple child elements, for example. The unconsumed portion may be used to allow continuous dragging of multiple scrolling or draggable elements, such as scrolling a list within a vertical drawer where the drawer begins dragging once the edge of inner scrolling content is reached.

Parameters
`target: View`	The descendent view controlling the nested scroll
`dxConsumed: Int`	Horizontal scroll distance in pixels already consumed by target
`dyConsumed: Int`	Vertical scroll distance in pixels already consumed by target
`dxUnconsumed: Int`	Horizontal scroll distance in pixels not consumed by target
`dyUnconsumed: Int`	Vertical scroll distance in pixels not consumed by target
`type: Int`	the type of input which cause this scroll event

Added in 1.16.0-alpha01

fun onNestedScroll(
    target: View,
    dxConsumed: Int,
    dyConsumed: Int,
    dxUnconsumed: Int,
    dyUnconsumed: Int,
    type: Int,
    consumed: IntArray
): Unit

React to a nested scroll in progress.

This method is called when a nested scrolling child invokes dispatchNestedScroll} or one of methods it overloads.

An implementation must report how many pixels of the the x and y scroll distances were consumed by this nested scrolling parent by adding the consumed distances to the consumed parameter. If this View also implements NestedScrollingChild3, consumed should also be passed up to it's nested scrolling parent so that the parent may also add any scroll distance it consumes. Index 0 corresponds to dx and index 1 corresponds to dy.

Parameters
`target: View`	The descendant view controlling the nested scroll
`dxConsumed: Int`	Horizontal scroll distance in pixels already consumed by target
`dyConsumed: Int`	Vertical scroll distance in pixels already consumed by target
`dxUnconsumed: Int`	Horizontal scroll distance in pixels not consumed by target
`dyUnconsumed: Int`	Vertical scroll distance in pixels not consumed by target
`type: Int`	the type of input which cause this scroll event
`consumed: IntArray`	Output. Upon this method returning, will contain the scroll distances consumed by this nested scrolling parent and the scroll distances consumed by any other parent up the view hierarchy

fun onNestedScrollAccepted(child: View, target: View, axes: Int, type: Int): Unit

React to the successful claiming of a nested scroll operation.

This method will be called after onStartNestedScroll returns true. It offers an opportunity for the view and its superclasses to perform initial configuration for the nested scroll. Implementations of this method should always call their superclass's implementation of this method if one is present.

Parameters
`child: View`	Direct child of this ViewParent containing target
`target: View`	View that initiated the nested scroll
`axes: Int`	Flags consisting of `SCROLL_AXIS_HORIZONTAL`, `SCROLL_AXIS_VERTICAL` or both
`type: Int`	the type of input which cause this scroll event

onStartNestedScroll

Added in 1.16.0-alpha01

fun onStartNestedScroll(child: View, target: View, axes: Int, type: Int): Boolean

React to a descendant view initiating a nestable scroll operation, claiming the nested scroll operation if appropriate.

This method will be called in response to a descendant view invoking startNestedScroll. Each parent up the view hierarchy will be given an opportunity to respond and claim the nested scrolling operation by returning true.

This method may be overridden by ViewParent implementations to indicate when the view is willing to support a nested scrolling operation that is about to begin. If it returns true, this ViewParent will become the target view's nested scrolling parent for the duration of the scroll operation in progress. When the nested scroll is finished this ViewParent will receive a call to onStopNestedScroll.

Parameters
`child: View`	Direct child of this ViewParent containing target
`target: View`	View that initiated the nested scroll
`axes: Int`	Flags consisting of `SCROLL_AXIS_HORIZONTAL`, `SCROLL_AXIS_VERTICAL` or both
`type: Int`	the type of input which cause this scroll event

Returns
`Boolean`	true if this ViewParent accepts the nested scroll operation

onStopNestedScroll

Added in 1.16.0-alpha01

fun onStopNestedScroll(target: View, type: Int): Unit

React to a nested scroll operation ending.

Perform cleanup after a nested scrolling operation. This method will be called when a nested scroll stops, for example when a nested touch scroll ends with a ACTION_UP or ACTION_CANCEL event. Implementations of this method should always call their superclass's implementation of this method if one is present.

Parameters
`target: View`	View that initiated the nested scroll
`type: Int`	the type of input which cause this scroll event

Parameters
`direction: Int`	the scroll direction: `FOCUS_UP` to go one page up or `FOCUS_DOWN` to go one page down

Returns
`Boolean`	true if the key event is consumed by this method, false otherwise

startNestedScroll

fun startNestedScroll(axes: Int): Boolean

startNestedScroll

Added in 1.16.0-alpha01

fun startNestedScroll(axes: Int, type: Int): Boolean

Begin a nestable scroll operation along the given axes, for the given input type.

A view starting a nested scroll promises to abide by the following contract:

The view will call startNestedScroll upon initiating a scroll operation. In the case of a touch scroll type this corresponds to the initial ACTION_DOWN. In the case of touch scrolling the nested scroll will be terminated automatically in the same manner as requestDisallowInterceptTouchEvent. In the event of programmatic scrolling the caller must explicitly call stopNestedScroll to indicate the end of the nested scroll.

If startNestedScroll returns true, a cooperative parent was found. If it returns false the caller may ignore the rest of this contract until the next scroll. Calling startNestedScroll while a nested scroll is already in progress will return true.

At each incremental step of the scroll the caller should invoke dispatchNestedPreScroll once it has calculated the requested scrolling delta. If it returns true the nested scrolling parent at least partially consumed the scroll and the caller should adjust the amount it scrolls by.

After applying the remainder of the scroll delta the caller should invoke dispatchNestedScroll, passing both the delta consumed and the delta unconsumed. A nested scrolling parent may treat these values differently. See onNestedScroll.

Parameters
`axes: Int`	Flags consisting of a combination of `SCROLL_AXIS_HORIZONTAL` and/or `SCROLL_AXIS_VERTICAL`.
`type: Int`	the type of input which cause this scroll event

Returns
`Boolean`	true if a cooperative parent was found and nested scrolling has been enabled for the current gesture.
