//设置一个唯一的ID，随便设置

//Notification管理器
Notification notification=new Notification(icon,tickertext,System.currentTimeMillis());
//后面的参数分别是显示在顶部通知栏的小图标，小图标旁的文字（短暂显示，自动消失）系统当前时间（不明白这个有什么用）
notification.defaults=Notification.DEFAULT_ALL; 
//这是设置通知是否同时播放声音或振动，声音为Notification.DEFAULT_SOUND
//振动为Notification.DEFAULT_VIBRATE;
//Light为Notification.DEFAULT_LIGHTS，在我的Milestone上好像没什么反应
//全部为Notification.DEFAULT_ALL
//如果是振动或者全部，必须在AndroidManifest.xml加入振动权限
PendingIntent pt=PendingIntent.getActivity(this, 0, new Intent(this,main.class), 0);
//点击通知后的动作，这里是转回main 这个Acticity
notification.setLatestEventInfo(this,title,content,pt);
nm.notify(notification_id, notification);

}
}

  AndroidManifest.xml加入权限：

 

<uses-permission android:name="android.permission.VIBRATE" /> 
<!-- 允许振动 -->
