TransitionManager
extends Object
| java.lang.Object | |
| ↳ | android.support.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:
<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.
