ViewDragHelper与Transition练习 2 | 3 | Android的框架层新增了ViewDragHelper这么一个类，官方的DrawerLayout就是通过它来实现的。 4 | ViewDragHelper是一个『拖拽控制器』，使用它可以用很少的代码实现很流畅的拖拽效果。Android在触摸这一块终于又进了一步。 5 | 6 | Trasition是4.4推出的，中文名字是：过渡动画，使用它可以做出各种界面变化后的过渡效果。 7 | Transition内部是对多个属性动画的封装，实现原理是通过记录View的初始状态和结束状态，然后通过属性动画进行播放 8 | 9 | 这个项目是自己对ViewDragHelper与Transition的一个小练习。 10 | 11 | # 截图： 12 |
