From class Transition
Transition |
addListener(@NonNull listener: Transition.TransitionListener)
Adds a listener to the set of listeners that are sent events through the life of an animation, such as start, repeat, and end.

Transition |
addTarget(@NonNull target: View)
Sets the target view instances that this Transition is interested in animating. By default, there are no targets, and a Transition will listen for changes on every view in the hierarchy below the sceneRoot of the Scene being transitioned into. Setting targets constrains the Transition to only listen for, and act on, these views. All other views will be ignored.
The target list is like the targetId list except this list specifies the actual View instances, not the ids of the views. This is an important distinction when scene changes involve view hierarchies which have been inflated separately; different views may share the same id but not actually be the same instance. If the transition should treat those views as the same, then addTarget(int) should be used instead of addTarget(View). If, on the other hand, scene changes involve changes all within the same view hierarchy, among views which do not necessarily have ids set on them, then the target list of views may be more convenient.

addTarget(@IdRes targetId: Int)
Adds the id of a target view that this Transition is interested in animating. By default, there are no targetIds, and a Transition will listen for changes on every view in the hierarchy below the sceneRoot of the Scene being transitioned into. Setting targetIds constrains the Transition to only listen for, and act on, views with these IDs. Views with different IDs, or no IDs whatsoever, will be ignored.
Note that using ids to specify targets implies that ids should be unique within the view hierarchy underneath the scene root.

Transition |
addTarget(@NonNull targetName: String)
Adds the transitionName of a target view that this Transition is interested in animating. By default, there are no targetNames, and a Transition will listen for changes on every view in the hierarchy below the sceneRoot of the Scene being transitioned into. Setting targetNames constrains the Transition to only listen for, and act on, views with these transitionNames. Views with different transitionNames, or no transitionName whatsoever, will be ignored.
Note that transitionNames should be unique within the view hierarchy.

Transition |
addTarget(@NonNull targetType: Class<*>)
Adds the Class of a target view that this Transition is interested in animating. By default, there are no targetTypes, and a Transition will listen for changes on every view in the hierarchy below the sceneRoot of the Scene being transitioned into. Setting targetTypes constrains the Transition to only listen for, and act on, views with these classes. Views with different classes will be ignored.
Note that any View that can be cast to targetType will be included, so if targetType is View.class, all Views will be included.

excludeChildren(@NonNull target: View, exclude: Boolean)
Whether to add the children of given target to the list of target children to exclude from this transition. The exclude parameter specifies whether the target should be added to or removed from the excluded list.
Excluding targets is a general mechanism for allowing transitions to run on a view hierarchy while skipping target views that should not be part of the transition. For example, you may want to avoid animating children of a specific ListView or Spinner. Views can be excluded either by their id, or by their instance reference, or by the Class of that view (eg, Spinner).
