* 1、 Activity和Task(栈)的关系
* 栈（Task）就像一个容器，而Activity就相当与填充这个容器的东西，
* 第一个东西（Activity）则会处于最下面，最后添加的东西（Activity）则会在最低端。从Task中取出东西（Activity）则是从最顶端取出，也
* 就是说最先取出的是最后添加的东西（Activity），一次类推，最后取出的是第一次添加的Activity，
* 而Activity在Task中的顺序是 可以控制的，那则在Activity跳转时用到Intent Flag
*
* 2、Intent.FLAG
* 如果activity在task存在，拿到最顶端,不会启动新的Activity
* intent.addFlags(Intent.FLAG_ACTIVITY_BROUGHT_TO_FRONT);
*
* 如果activity在task存在，将Activity之上的所有Activity结束掉
* intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
*
* 默认的跳转类型,将Activity放到一个新的Task中
* intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
*
* 如果Activity已经运行到了Task，再次跳转不会再运行这个Activity
* intent.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
