发送通知：通过NotificationManager的实例 manager.notify(通知的id，通知实例Notification);
所以先要获取manager：NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
然后需要Notification对象：Notification notification = new Notification(R.drawable.ic_launcher, "this is ticker", System.currentTimeMillis());
(通知栏图标，通知栏信息，下拉时间)
Notification下拉的信息呢：notification.setLatestEventInfo(MainActivity.this, "title","text", pendingIntent);
(context，下拉标题，下拉内容，点击时执行的延迟意图pendingintent)
所以还得有pendingIntent：PendingIntent pendingIntent = PendingIntent.getActivity(MainActivity.this, 0, intent,PendingIntent.FLAG_UPDATE_CURRENT);
(context，这里通常传入0，目的地，构造时的flag)
pendIntent四个值：
取消通知：同样通过manager，manager.cancel(通知的id);
给通知添加音频
Uri soundUri = Uri.fromFile(new File("/system/media/audio/ringtones")); notification.sound = soundUri;
给通知设置LED灯闪烁
notification.ledARGB = Color.RED;// 颜色红——测试只有红和绿可用，蓝色用不了 notification.ledOffMS = 1000; // 熄灭时长 notification.ledOnMS = 1000;// 闪光灯亮起的时长 notification.flags = Notification.FLAG_SHOW_LIGHTS;// 一旦设置了LED，必须为flags属性添加FLAG_SHOW_LIGHTS标志位
给通知增加震动——需要声明权限
// 收到通知，立即震动1秒，静止一秒，再震动1秒————震动需要权限 // <uses-permission android:name="android.permission.VIBRATE" /> long vibrates[] = { 0, 1000, 1000, 1000 }; notification.vibrate = vibrates;
注：可以直接一行代码表示使用默认：notification.defaults = Notification.DEFAULT_ALL;——无需声明权限
