ChangeTransform

Kotlin |Java

open class ChangeTransform : Transition

kotlin.Any
↳	androidx.transition.Transition
	↳	androidx.transition.ChangeTransform

This Transition captures scale and rotation for Views before and after the scene change and animates those changes during the transition. A change in parent is handled as well by capturing the transforms from the parent before and after the scene change and animating those during the transition.

Summary

Inherited constants

From class Transition Int MATCH_ID With setMatchOrder(int...), chooses to match by android.view.View#getId(). Negative IDs will not be matched. Int MATCH_INSTANCE With setMatchOrder(int...), chooses to match by View instance. Int MATCH_ITEM_ID With setMatchOrder(int...), chooses to match by the android.widget.Adapter item id. When android.widget.Adapter#hasStableIds() returns false, no match will be made for items. Int MATCH_NAME With setMatchOrder(int...), chooses to match by android.view.View#getTransitionName(). Null names will not be matched.

Inherited functions

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. Transition 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
