//1.1.4 p18 3种Notification
//布局三个Button
/*
普通、折叠式、悬挂式
 */
/*
1.普通Notification
创建Builder对象，PendingIntent控制跳转
 */
/*
2.折叠式Notification
折叠式Notification是一种自定义视图的Notification，用来显示长文本和一些自定义的布局场景
它有两种状态：
一：普通状态下的视图(如果不是自定义与普通Notification一样)
二：展开状态下的视图，需要自定义视图
这个视图显示的进程和创建视图的不是一个进程，需要使用RemoteViews
 */
/*
3.悬挂式Notification
悬挂式Notification是5.0新增方式
不需要下拉通知栏就直接显示出来悬挂在屏幕上方，焦点仍在用户操作界面，过几秒自动消失
调用setFullScreenIntent
 */
/*
通知的显示等级：
5.0加入了显示等级
VISIBILITY_PUBLIC:任何情况都会显示通知
VISIBILITY_PRIVATE:只有在没有锁屏时会显示通知
VISIBILITY_SECRET:只有在pin,password等安全锁和没有锁屏时会显示通知
调用builder.setVisibility(Notification.VISIBILITY_PUBLIC);
