Get Started

1. ActivityA jump to ActivityB，when need use “SharedElementTransition”（ActivityA 跳转到ActivityB，当需要用到“共享元素转场动画”时）:

ActivityA edit code as below（编辑ActivityA 的代码如下）:

    ElementTransition.startActivity(intent, activityA, view1, view2, view...);

ActivityB edit code as below（编辑ActivityB 的代码如下）:

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        ......
        ElementTransition.runEnterAnim(activityB);
        ......
    }

2. ActivityB back to ActivityA（ActivityB Ac回到ActivityA）:

ActivityB edit code like this（编辑ActivityB 的代码，类似代码如下）:

    @Override
    public void onBackPressed() {
        ElementTransition.runExitAnim(activityB);
    }

好了，就这样了，让大家失望了，我可能失去了奋斗的动力，但迟早会回来的。
