CoordinatorLayout

public class CoordinatorLayout extends ViewGroup implements NestedScrollingParent2, NestedScrollingParent3


CoordinatorLayout is a super-powered FrameLayout.

CoordinatorLayout is intended for two primary use cases:

  1. As a top-level application decor or chrome layout
  2. As a container for a specific interaction with one or more child views

By specifying Behaviors for child views of a CoordinatorLayout you can provide many different interactions within a single parent and those views can also interact with one another. View classes can specify a default behavior when used as a child of a CoordinatorLayout by implementing the AttachedBehavior interface.

Behaviors may be used to implement a variety of interactions and additional layout modifications ranging from sliding drawers and panels to swipe-dismissable elements and buttons that stick to other elements as they move and animate.

Children of a CoordinatorLayout may have an anchor. This view id must correspond to an arbitrary descendant of the CoordinatorLayout, but it may not be the anchored child itself or a descendant of the anchored child. This can be used to place floating views relative to other arbitrary content panes.

Children can specify insetEdge to describe how the view insets the CoordinatorLayout. Any child views which are set to dodge the same inset edges by dodgeInsetEdges will be moved appropriately so that the views do not overlap.

public void onNestedPreScroll(
    @NonNull View target,
    int dx,
    int dy,
    @NonNull int[] consumed,
    int type
)

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
@NonNull View target

View that initiated the nested scroll

int dx

Horizontal scroll distance in pixels

int dy

Vertical scroll distance in pixels

@NonNull int[] consumed

Output. The horizontal and vertical scroll distance consumed by this parent

int type

the type of input which cause this scroll event

onNestedScroll

public void onNestedScroll(
    @NonNull View target,
    int dxConsumed,
    int dyConsumed,
    int dxUnconsumed,
    int dyUnconsumed
)

onNestedScroll

Added in 1.1.0
public void onNestedScroll(
    @NonNull View target,
    int dxConsumed,
    int dyConsumed,
    int dxUnconsumed,
    int dyUnconsumed,
    int type
)

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
@NonNull View target

The descendent view controlling the nested scroll

int dxConsumed

Horizontal scroll distance in pixels already consumed by target

int dyConsumed

Vertical scroll distance in pixels already consumed by target

int dxUnconsumed

Horizontal scroll distance in pixels not consumed by target

int dyUnconsumed

Vertical scroll distance in pixels not consumed by target

int type

the type of input which cause this scroll event

onNestedScroll

Added in 1.1.0
public void onNestedScroll(
    @NonNull View target,
    int dxConsumed,
    int dyConsumed,
    int dxUnconsumed,
    int dyUnconsumed,
    int type,
    @NonNull int[] consumed
)

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.

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
@NonNull View target

The descendant view controlling the nested scroll

int dxConsumed

Horizontal scroll distance in pixels already consumed by target

int dyConsumed

Vertical scroll distance in pixels already consumed by target

int dxUnconsumed

Horizontal scroll distance in pixels not consumed by target

int dyUnconsumed

Vertical scroll distance in pixels not consumed by target

int type

the type of input which cause this scroll event

@NonNull int[] consumed

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

onNestedScrollAccepted

public void onNestedScrollAccepted(@NonNull View child, @NonNull View target, int axes)

onNestedScrollAccepted

Added in 1.1.0
public void onNestedScrollAccepted(
    @NonNull View child,
    @NonNull View target,
    int axes,
    int type
)

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
@NonNull View child

Direct child of this ViewParent containing target

@NonNull View target

View that initiated the nested scroll

int axes

Flags consisting of SCROLL_AXIS_HORIZONTAL, SCROLL_AXIS_VERTICAL or both

int type

the type of input which cause this scroll event

onStartNestedScroll

onStartNestedScroll

Added in 1.1.0
public boolean onStartNestedScroll(
    @NonNull View child,
    @NonNull View target,
    int axes,
    int type
)

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
@NonNull View child

Direct child of this ViewParent containing target

@NonNull View target

View that initiated the nested scroll

int axes

Flags consisting of SCROLL_AXIS_HORIZONTAL, SCROLL_AXIS_VERTICAL or both

int type

the type of input which cause this scroll event

Returns
boolean

true if this ViewParent accepts the nested scroll operation

onStopNestedScroll

Added in 1.1.0
public void onStopNestedScroll(@NonNull View target, int type)

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
@NonNull View target

View that initiated the nested scroll

int type

the type of input which cause this scroll event
