*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IntentFlag
*
*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);
