TransitionManager
extends Object
| java.lang.Object | |
| ↳ | android.transition.TransitionManager |
This class manages the set of transitions that fire when there is a
change of Scene. To use the manager, add scenes along with
transition objects with calls to setTransition(Scene, Transition)
or setTransition(Scene, Scene, Transition). Setting specific
transitions for scene changes is not required; by default, a Scene change
will use AutoTransition to do something reasonable for most
situations. Specifying other transitions for particular scene changes is
only necessary if the application wants different transition behavior
in these situations.
TransitionManagers can be declared in XML resource files inside the
res/transition directory. TransitionManager resources consist of
the transitionManagertag name, containing one or more
transition tags, each of which describe the relationship of
that transition to the from/to scene information in that tag.
For example, here is a resource file that declares several scene
transitions:
Developers
<transitionManager xmlns:android="http://schemas.android.com/apk/res/android">
<transition android:fromScene="@layout/transition_scene1"
android:toScene="@layout/transition_scene2"
android:transition="@transition/changebounds"/>
<transition android:fromScene="@layout/transition_scene2"
android:toScene="@layout/transition_scene1"
android:transition="@transition/changebounds"/>
<transition android:toScene="@layout/transition_scene3"
android:transition="@transition/changebounds_fadein_together"/>
<transition android:fromScene="@layout/transition_scene3"
android:toScene="@layout/transition_scene1"
android:transition="@transition/changebounds_fadeout_sequential"/>
<transition android:fromScene="@layout/transition_scene3"
android:toScene="@layout/transition_scene2"
android:transition="@transition/changebounds_fadeout_sequential"/>
</transitionManager>
For each of the fromScene and toScene attributes,
there is a reference to a standard XML layout file. This is equivalent to
creating a scene from a layout in code by calling
getSceneForLayout(ViewGroup, int, Context). For the
transition attribute, there is a reference to a resource
file in the res/transition directory which describes that
transition.

void beginDelayedTransition (ViewGroup sceneRoot, Transition transition)
Convenience method to animate to a new scene defined by all changes within the given scene root between calling this method and the next rendering frame. Calling this method causes TransitionManager to capture current values in the scene root and then post a request to run a transition on the next frame. At that time, the new values in the scene root will be captured and changes will be animated. There is no need to create a Scene; it is implied by changes which take place between calling this method and the next frame when the transition begins.
Calling this method several times before the next frame (for example, if unrelated code also wants to make dynamic changes and run a transition on the same scene root), only the first call will trigger capturing values and exiting the current scene. Subsequent calls to the method with the same scene root during the same frame will be ignored.
Passing in null for the transition parameter will
cause the TransitionManager to use its default transition.
| Parameters | |
|---|---|
sceneRoot |
ViewGroup:
The root of the View hierarchy to run the transition on. |
transition |
Transition:
The transition to use for this change. A
value of null causes the TransitionManager to use the default transition.
|
void beginDelayedTransition (ViewGroup sceneRoot)
Convenience method to animate, using the default transition,
to a new scene defined by all changes within the given scene root between
calling this method and the next rendering frame.
Equivalent to calling beginDelayedTransition(ViewGroup, Transition)
with a value of null for the transition parameter.
| Parameters | |
|---|---|
sceneRoot |
ViewGroup:
The root of the View hierarchy to run the transition on.
|
void endTransitions (ViewGroup sceneRoot)
Ends all pending and ongoing transitions on the specified scene root.
| Parameters | |
|---|---|
sceneRoot |
ViewGroup:
The root of the View hierarchy to end transitions on.
|
void go (Scene scene, Transition transition)
Convenience method to simply change to the given scene using the given transition.
Passing in null for the transition parameter will
result in the scene changing without any transition running, and is
equivalent to calling exit() on the scene root's
current scene, followed by enter() on the scene
specified by the scene parameter.
| Parameters | |
|---|---|
scene |
Scene:
The Scene to change to |
transition |
Transition:
The transition to use for this scene change. A
value of null causes the scene change to happen with no transition.
|
void go (Scene scene)
Convenience method to simply change to the given scene using the default transition for TransitionManager.
| Parameters | |
|---|---|
scene |
Scene:
The Scene to change to
|
void setTransition (Scene scene, Transition transition)
Sets a specific transition to occur when the given scene is entered.
| Parameters | |
|---|---|
scene |
Scene:
The scene which, when applied, will cause the given
transition to run. |
transition |
Transition:
The transition that will play when the given scene is
entered. A value of null will result in the default behavior of
using the default transition instead.
|
void setTransition (Scene fromScene, Scene toScene, Transition transition)
Sets a specific transition to occur when the given pair of scenes is exited/entered.
| Parameters | |
|---|---|
fromScene |
Scene:
The scene being exited when the given transition will
be run |
toScene |
Scene:
The scene being entered when the given transition will
be run |
transition |
Transition:
The transition that will play when the given scene is
entered. A value of null will result in the default behavior of
using the default transition instead.
|
void transitionTo (Scene scene)
Change to the given scene, using the appropriate transition for this particular scene change (as specified to the TransitionManager, or the default if no such transition exists).
| Parameters | |
|---|---|
scene |
Scene:
The Scene to change to
