In this sample, we set up an AnimationListener 70 for this Animation, and start our Transition on [onAnimationEnd][3]. 71 72 Transition is started by calling [TransitionManager.go][4]. We don't 73 instantiate a Scene for the initial state of Transition, as we never 74 go back. One thing we need to be careful here is that we need to 75 populate the content of Views after starting the Transition. 76 77 [1]: https://developer.android.com/reference/android/transition/package-summary.html 78 [2]: http://developer.android.com/reference/android/support/v4/app/Fragment.html#onCreateAnimation(int, boolean, int) 79 [3]: http://developer.android.com/reference/android/view/animation/Animation.AnimationListener.html#onAnimationEnd(android.view.animation.Animation) 80 [4]: http://developer.android.com/reference/android/transition/TransitionManager.html#go(android.transition.Scene) 81 ]]> 82 </intro> 83 </metadata> 84 85 </sample> 86
