Android BasicTransition Sample

A basic app showing how to use the Transition framework introduced in KitKat. The app shows radioboxes to select between different Scenes, and uses various ways to transition between them.


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.

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.
