AutoTransition

A TransitionSet is a parent of child transitions (including other TransitionSets). Using TransitionSets enables more complex choreography of transitions, where some sets play ORDERING_TOGETHER and others play ORDERING_SEQUENTIAL. For example, AutoTransition uses a TransitionSet to sequentially play a Fade(Fade.OUT), followed by a ChangeBounds, followed by a Fade(Fade.OUT) transition.

A TransitionSet can be described in a resource file by using the tag transitionSet, along with the standard attributes of TransitionSet and Transition. Child transitions of the TransitionSet object can be loaded by adding those child tags inside the enclosing transitionSet tag. For example, the following xml describes a TransitionSet that plays a Fade and then a ChangeBounds transition on the affected view targets:

     <transitionSet xmlns:android="http://schemas.android.com/apk/res/android"
             android:transitionOrdering="sequential">
         <fade/>
         <changeBounds/>
     </transitionSet>

Summary

Constants

ORDERING_SEQUENTIAL

added in version 25.1.0

int ORDERING_SEQUENTIAL

A flag used to indicate that the child transitions of this set should play in sequence; when one child transition ends, the next child transition begins. Note that a transition does not end until all instances of it (which are playing on all applicable targets of the transition) end.

Constant Value: 1 (0x00000001)

ORDERING_TOGETHER

added in version 25.1.0

int ORDERING_TOGETHER

A flag used to indicate that the child transitions of this set should all start at the same time.

Constant Value: 0 (0x00000000)

Public constructors

TransitionSet

added in version 25.1.0

TransitionSet ()

Constructs an empty transition set. Add child transitions to the set by calling addTransition(Transition) )}. By default, child transitions will play together.

TransitionSet

added in version 26.1.0

TransitionSet (Context context, 
                AttributeSet attrs)

Parameters
`context`	`Context`
`attrs`	`AttributeSet`

Public methods

addListener

added in version 25.1.0

TransitionSet addListener (Transition.TransitionListener listener)

Adds a listener to the set of listeners that are sent events through the life of an animation, such as start, repeat, and end.

Parameters
`listener`	`Transition.TransitionListener`: the listener to be added to the current set of listeners for this animation.

Returns
`TransitionSet`	This transition object.

addTarget

added in version 25.1.0

TransitionSet addTarget (View target)

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.

Parameters
`target`	`View`: A View on which the Transition will act, must be non-null.

Returns
`TransitionSet`	The Transition to which the target is added. Returning the same object makes it easier to chain calls during construction, such as `transitionSet.addTransitions(new Fade()).addTarget(someView);`

addTarget

added in version 25.1.0

TransitionSet addTarget (int targetId)

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.

Parameters
`targetId`	`int`: The id of a target view, must be a positive number.

Returns
`TransitionSet`	The Transition to which the targetId is added. Returning the same object makes it easier to chain calls during construction, such as `transitionSet.addTransitions(new Fade()).addTarget(someId);`

addTarget

added in version 26.1.0

TransitionSet addTarget (Class targetType)

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.

Parameters
`targetType`	`Class`: The type to include when running this transition.

Returns
`TransitionSet`	The Transition to which the target class was added. Returning the same object makes it easier to chain calls during construction, such as `transitionSet.addTransitions(new Fade()).addTarget(ImageView.class);`

addTarget

added in version 26.1.0

TransitionSet addTarget (String targetName)

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.

Parameters
`targetName`	`String`: The transitionName of a target view, must be non-null.

Returns
`TransitionSet`	The Transition to which the target transitionName is added. Returning the same object makes it easier to chain calls during construction, such as `transitionSet.addTransitions(new Fade()).addTarget(someName);`

addTransition

added in version 25.1.0

TransitionSet addTransition (Transition transition)

Adds child transition to this set. The order in which this child transition is added relative to other child transitions that are added, in addition to the
