The app shows radioboxes to select between different Scenes, +and uses various ways to transition between them. + +Introduction +------------ + +A Scene is an encapsulation of the state of a view hierarchy, +including the views in that hierarchy and the various values +(layout-related and otherwise) that those views have. A scene can be +defined by a layout hierarchy directly or by code which sets up the +scene dynamically as it is entered. -This sample demonstrates the basic use of the transition framework introduced in KitKat. - Select each of the RadioButtons to switch between the Scenes. +A Transition is a mechanism to automatically animate changes that +occur when a new scene is entered. Some transition capabilities are +automatic. That is, entering a scene may cause animations to run which +fade out views that go away, changeBounds and resize existing views +that change, and fade in views that become visible. There are +additional transitions that can animate other attributes, such as +color changes, and which can optionally be specified to take place +during particular scene changes. Finally, developers can define their +own Transition subclasses which monitor particular property changes +and which run custom animations when those properties change values. + +TransitionManager is used to specify custom transitions for particular +scene changes, and to cause scene changes with specific transitions to +take place.
