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.
|
||
|
|
|
||
|
|
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.
|
||
|
|
|
||
|
|
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.
