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

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.

int ORDERING_TOGETHER

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

Public methods

TransitionSet addListener(Transition.TransitionListener listener)

TransitionSet addTarget(int targetId)

Adds the id of a target view that this Transition is interested in animating.

TransitionSet addTarget(String targetName)

Adds the transitionName of a target view that this Transition is interested in animating.

TransitionSet addTarget(Class<?> targetType)

Adds the Class of a target view that this Transition is interested in animating.

TransitionSet addTransition(Transition transition)

Adds child transition to this set.

void captureEndValues(TransitionValues transitionValues)

Captures the values in the end scene for the properties that this transition monitors.

void captureStartValues(TransitionValues transitionValues)

int getOrdering()

Returns the ordering of this TransitionSet.

Transition getTransitionAt(int index)

Returns the child Transition at the specified position in the TransitionSet.

int getTransitionCount()

Returns the number of child transitions in the TransitionSet.

TransitionSet removeListener(Transition.TransitionListener listener)
