A subclass of ConstraintLayout that supports animating between various states Added in 2.0

A MotionLayout is a subclass of ConstraintLayout which supports transitions between between various states (ConstraintSet) defined in MotionScenes.

Note:MotionLayout is available as a support library that you can use on Android systems starting with API level 14 (ICS).

MotionLayout links to and requires a MotionScene file. The file contains one top level tag "MotionScene"

LayoutDescription

Tags	Description
<StateSet>	Describes states supported by the system (optional)
<ConstraintSet>	Describes a constraint set
<Transition>	Describes a transition between two states or ConstraintSets
<ViewTransition>	Describes a transition of a View within a states or ConstraintSets

Transition

Attributes	Description
android:id	The id of the Transition
constraintSetStart	ConstraintSet to be used as the start constraints or a layout file to get the constraint from
constraintSetEnd	ConstraintSet to be used as the end constraints or a layout file to get the constraint from
motionInterpolator	The ability to set an overall interpolation (easeInOut, linear, etc.)
duration	Length of time to take to perform the transition
staggered	Overrides the Manhattan distance from the top most view in the list of views. For any view of stagger value S(Vi) With the transition stagger value of TS (from 0.0 - 1.0) The duration of the animation is duration The views animation duration DS = duration * (1 -TS) Call the stagger fraction SFi = (S(Vi) - S(V0)) / (S(Vn) - S(V0)) The view starts animating at: (duration-DS) * SFi
pathMotionArc	The path will move in arc (quarter ellipses) key words {startVertical | startHorizontal | flip | none }
autoTransition	automatically transition from one state to another. key words {none, jumpToStart, jumpToEnd, animateToStart, animateToEnd}
transitionFlags	flags that adjust the behaviour of Transitions. supports {none, beginOnFirstDraw} begin on first draw forces the transition's clock to start when it is first displayed not when the begin is called
layoutDuringTransition	Configures MotionLayout on how to react to requestLayout calls during transitions. Allowed values are {ignoreRequest, honorRequest}
<OnSwipe>	Adds support for touch handling (optional)
<OnClick>	Adds support for triggering transition (optional)
<KeyFrameSet>	Describes a set of Key object which modify the animation between constraint sets.

• A transition is typically defined by specifying its start and end ConstraintSets. You also have the possibility to not specify them, in which case such transition will become a Default transition. That Default transition will be applied between any state change that isn't explicitly covered by a transition.
• The starting state of the MotionLayout is defined to be the constraintSetStart of the first transition.
• If no transition is specified (or only a default Transition) the MotionLayout tag must contain a app:currentState to define the starting state of the MotionLayout

ViewTransition

Attributes	Description
android:id	The id of the ViewTransition
viewTransitionMode	currentState, allStates, noState transition affect the state of the view in the current constraintSet or all ConstraintSets or non if noState the ViewTransitions are run asynchronous
onStateTransition	actionDown or actionUp run transition if on touch down or up if view matches motionTarget
motionInterpolator	The ability to set an overall interpolation key words {easeInOut, linear, etc.}
duration	Length of time to take to perform the ViewTransition
pathMotionArc	The path will move in arc (quarter ellipses) key words {startVertical | startHorizontal | flip | none }
motionTarget	Apply ViewTransition matching this string or id.
setsTag	set this tag at end of transition
clearsTag	clears this tag at end of transition
ifTagSet	run transition if this tag is set on view
ifTagNotSet	run transition if this tag is not set on view/td>
<OnSwipe>	Adds support for touch handling (optional)
<OnClick>	Adds support for triggering transition (optional)
<KeyFrameSet>	Describes a set of Key object which modify the animation between constraint sets.

• A Transition is typically defined by specifying its start and end ConstraintSets. You also have the possibility to not specify them, in which case such transition will become a Default transition. That Default transition will be applied between any state change that isn't explicitly covered by a transition.
• The starting state of the MotionLayout is defined to be the constraintSetStart of the first transition.
• If no transition is specified (or only a default Transition) the MotionLayout tag must contain a app:currentState to define the starting state of the MotionLayout

maxVelocity	limit the maximum velocity (in progress/sec) of the animation will on touch up. Default 4
dragDirection	which side to swipe from {dragUp|dragDown|dragLeft|dragRight}
maxAcceleration	how quickly the animation will accelerate (progress/sec/sec) and decelerate on touch up. Default 1.2
dragScale	scale factor to adjust the swipe by. (e.g. 0.5 would require you to move 2x as much)
dragThreshold	How much to drag before swipe gesture runs. Important for mult-direction swipe. Default is 10. 1 is very sensitive.

defaultState	The constraint set or layout to use
<State>	The side of the object to move

State

android:id	Id of the State
constraints	Id of the ConstraintSet or the Layout file
<Variant>	a different constraintSet/layout to choose if the with or height matches

Variant

region_widthLessThan	Match if width less than
region_widthMoreThan	Match if width more than

ConstraintSet

android:id	The id of the ConstraintSet
deriveConstraintsFrom	The id of another constraintSet which defines the constraints not define in this set. If not specified the layout defines the undefined constraints.
<Constraint>	A ConstraintLayout Constraints + other attributes associated with a view

Constraint

Constraint supports two forms:

1: All of ConstraintLayout + the ones listed below + <CustomAttribute> .

Or

2: Combination of tags: <Layout> <PropertySet> <Transform> <Motion> <CustomAttribute> . The advantage of using these is that if not present the attributes are taken from the base layout file. This saves from replicating all the layout tags if only a Motion tag is needed. If is used then all layout attributes in the base are ignored.

pathMotionArc	the path will move in arc (quarter ellipses) or key words {startVertical | startHorizontal | none }
transitionPathRotate	(float) rotate object relative to path taken
drawPath	draw the path the layout will animate animate
progress	call method setProgress(float) on this view (used to talk to nested ConstraintLayouts etc.)

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

Added in 2.2.0

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 2.2.0

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

Added in 2.2.0

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

Added in 2.2.0

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 2.2.0

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
