Interfaces

A transition listener receives notifications from a transition.

Classes

ArcMotion	A PathMotion that generates a curved path along an arc on an imaginary circle containing the two points.
AutoTransition	Utility class for creating a default transition that automatically fades, moves, and resizes views during a scene change.
ChangeBounds	This transition captures the layout bounds of target views before and after the scene change and animates those changes during the transition.
ChangeClipBounds	ChangeClipBounds captures the `android.view.View#getClipBounds()` before and after the scene change and animates those changes during the transition.
ChangeImageTransform	This Transition captures an ImageView's matrix before and after the scene change and animates it during the transition.
ChangeScroll	This transition captures the scroll properties of targets before and after the scene change and animates any changes.
ChangeTransform	This Transition captures scale and rotation for Views before and after the scene change and animates those changes during the transition.
CircularPropagation	A propagation that varies with the distance to the epicenter of the Transition or center of the scene if no epicenter exists.
Explode	This transition tracks changes to the visibility of target views in the start and end scenes and moves views in or out from the edges of the scene.
Fade	This transition tracks changes to the visibility of target views in the start and end scenes and fades views in or out when they become visible or non-visible.
PathMotion	This base class can be extended to provide motion along a Path to Transitions.
PatternPathMotion	A PathMotion that takes a Path pattern and applies it to the separation between two points.
Scene	A scene represents the collection of values that various properties in the View hierarchy will have when the scene is applied.
SidePropagation	A `TransitionPropagation` that propagates based on the distance to the side and, orthogonally, the distance to epicenter.
Slide	This transition tracks changes to the visibility of target views in the start and end scenes and moves views in or out from one of the edges of the scene.
Transition	A Transition holds information about animations that will be run on its targets during a scene change.
TransitionInflater	This class inflates scenes and transitions from resource files.
TransitionListenerAdapter	This adapter class provides empty implementations of the methods from .
TransitionManager	This class manages the set of transitions that fire when there is a change of `Scene`.
TransitionPropagation	Extend `TransitionPropagation` to customize start delays for Animators created in `Transition#createAnimator(ViewGroup, TransitionValues, TransitionValues)`.
TransitionSet	A TransitionSet is a parent of child transitions (including other TransitionSets).
TransitionValues	Data structure which holds cached values for the transition.
Visibility	This transition tracks changes to the visibility of target views in the start and end scenes.
VisibilityPropagation	Base class for `TransitionPropagation`s that care about View Visibility and the center position of the View.

Extension functions summary

For Transition
Transition.TransitionListener	`Transition.addListener(crossinline onEnd: (transition: Transition) -> Unit = {}, crossinline onStart: (transition: Transition) -> Unit = {}, crossinline onCancel: (transition: Transition) -> Unit = {}, crossinline onResume: (transition: Transition) -> Unit = {}, crossinline onPause: (transition: Transition) -> Unit = {})` Add a listener to this Transition using the provided actions.
Transition.TransitionListener	`Transition.doOnCancel(crossinline action: (transition: Transition) -> Unit)` Add an action which will be invoked when this transition has been cancelled.
Transition.TransitionListener	`Transition.doOnEnd(crossinline action: (transition: Transition) -> Unit)` Add an action which will be invoked when this transition has ended.
Transition.TransitionListener	`Transition.doOnPause(crossinline action: (transition: Transition) -> Unit)` Add an action which will be invoked when this transition has been paused.
Transition.TransitionListener	`Transition.doOnResume(crossinline action: (transition: Transition) -> Unit)` Add an action which will be invoked when this transition has resumed after a pause.
Transition.TransitionListener	`Transition.doOnStart(crossinline action: (transition: Transition) -> Unit)` Add an action which will be invoked when this transition has started.
