1 Android FragmentTransition Sample
2 ===================================
3
4 This sample demonstrates how to start a Transition after a Fragment Transaction.
5
6 Introduction
7 ------------
8
9 This sample uses [the Transition framework][1] to show a nice visual effect on
10 Fragment Transaction.
11
12 Animation for fragment _transaction_ can be customized by overriding
13 [onCreateAnimation][2]. In this sample, we set up an AnimationListener
14 for this Animation, and start our Transition on [onAnimationEnd][3].
15
16 Transition is started by calling [TransitionManager.go][4]. We don't
17 instantiate a Scene for the initial state of Transition, as we never
18 go back. One thing we need to be careful here is that we need to
19 populate the content of Views after starting the Transition.
