1 2Android BasicTransition Sample 3=================================== 4 5A basic app showing how to use the Transition framework introduced in 6KitKat. The app shows radioboxes to select between different Scenes, 7and uses various ways to transition between them. 8 9Introduction 10------------ 11 12A Scene is an encapsulation of the state of a view hierarchy, 13including the views in that hierarchy and the various values 14(layout-related and otherwise) that those views have. A scene can be 15defined by a layout hierarchy directly or by code which sets up the 16scene dynamically as it is entered. 17 18A Transition is a mechanism to automatically animate changes that 19occur when a new scene is entered. Some transition capabilities are 20automatic. That is, entering a scene may cause animations to run which 21fade out views that go away, changeBounds and resize existing views 22that change, and fade in views that become visible. There are 23additional transitions that can animate other attributes, such as 24color changes, and which can optionally be specified to take place 25during particular scene changes. Finally, developers can define their 26own Transition subclasses which monitor particular property changes 27and which run custom animations when those properties change values. 28 29TransitionManager is used to specify custom transitions for particular 30scene changes, and to cause scene changes with specific transitions to 31take place. 32 33Pre-requisites 34-------------- 35 36- Android SDK 27 37- Android Build Tools v27.0.2 38- Android Support Repository 39 40Screenshots 41------------- 42 43<img src="screenshots/main.png" height="400" alt="Screenshot"/> 44 45Getting Started 46--------------- 47 48This sample uses the Gradle build system.
