通知的主要功能是提示功能。例如：短信、推送信息等等。
大体使用步骤：
1.获取状态通知栏管理
NotificationManager 是一个系统Service，所以必须通过 getSystemService(NOTIFICATION_SERVICE)方法来获取。
notificationManager = (NotificationManager) this .getSystemService(NOTIFICATION_SERVICE);
2.实例化通知栏构造器NotificationCompat.Builder
3.设置NotificationCompat.Builder
4.设置PendingIntent
5.显示
方法或参数介绍：
1.PendingIntent
PendingIntent.getBroadcast(context, requestCode, intent, flags)
PendingIntent.getActivities(context, requestCode, intents, flags)
PendingIntent.getService(context, requestCode, intent, flags)
中的flags属性参数：
FLAG_ONE_SHOT 表示返回的PendingIntent仅能执行一次，执行完后自动取消
FLAG_NO_CREATE 表示如果描述的PendingIntent不存在，并不创建相应的PendingIntent，而是返回NULL
FLAG_CANCEL_CURRENT 表示相应的PendingIntent已经存在，则取消前者，然后创建新的PendingIntent
FLAG_UPDATE_CURRENT 表示更新的PendingIntent
2.notification.flags参数介绍
Notification.FLAG_SHOW_LIGHTS //三色灯提醒，在使用三色灯提醒时候必须加该标志符
Notification.FLAG_ONGOING_EVENT //发起正在运行事件（活动中）
Notification.FLAG_INSISTENT //让声音、振动无限循环，直到用户响应 （取消或者打开）
Notification.FLAG_ONLY_ALERT_ONCE //发起Notification后，铃声和震动均只执行一次
Notification.FLAG_AUTO_CANCEL //用户单击通知后自动消失
Notification.FLAG_NO_CLEAR //只有全部清除时，Notification才会清除 ，不清楚该通知(QQ的通知无法清除，就是用的这个)
Notification.FLAG_FOREGROUND_SERVICE //表示正在运行的服务
使用方法：
在设置完属性后，设置
Notification notification =builder.build(); notification.flags =Notification.FLAG_ONLY_ALERT_ONCE;
3.setVibrate(long[] pattern)
设置震动，需要权限.
<uses-permission android:name="android.permission.VIBRATE"/>
4.builder.setOngoing( )
设置为ture，表示它为一个正在进行的通知。简单的说，当为ture时，不可以被侧滑消失。

使用自定义Notification，就要使用RemoteViews。

实现代码：
