获取NotificationManager

NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);

初始化Notification

Notification notification = new Notification();
notification.icon = R.drawable.ic_launcher;
notification.defaults = Notification.DEFAULT_ALL;
notification.flags |= Notification.FLAG_AUTO_CANCEL;
notification.tickerText="我是个消息";
notification.when = System.currentTimeMillis();

/**
* notification.defaults = Notification.DEFAULT_SOUND; 默认声音
*  使用自定义声音 notification.sound =  Uri.parse(uriString);
*
* notification.defaults = Notification.DEFAULT_LIGHTS; 默认闪光灯
*  权限：<uses-permission android:name="android.permission.FLASHLIGHT" />
*  notification.ledARGB = 0xff00ff00; 颜色
*  notification.ledOnMS = 300; //亮的时间
*  notification.ledOffMS = 1000; //灭的时间
*
* notification.defaults = Notification.DEFAULT_VIBRATE; 默认震动
*  权限：<uses-permission android:name="android.permission.VIBRATE" />
*  long[] vibrate = {0,100,200,300};
*  notification.vibrate = vibrate; 震动的时间
*/

/**
* notification.flags |= Notification.FLAG_AUTO_CANCEL;自动取消
* 其他属性：
* Notification.FLAG_INSISTENT;  //让声音、振动无限循环，直到用户响应
* Notification.FLAG_AUTO_CANCEL;   //通知被点击后，自动消失
* Notification.FLAG_NO_CLEAR;  //点击'Clear'时，不清楚该通知
*/

/**
* notification.tickerText 标题
* notification.when 提醒时间
*/

Intent intent = new Intent();
PendingIntent pIntent = PendingIntent.getActivity(
MainActivity.this, requestCode, intent, flags);
notification.contentIntent = pIntent;
notification.setLatestEventInfo(MainActivity.this, "我改的标题","我改的内容", pIntent);

/**
* intent 点击通知时的意图
* notification.setLatestEventInfo 下拉状态时显示的效果
* pendingIntent中的flag：
* *     0：不带数据
*  PendingIntent.FLAG_CANCEL_CURRENT：最后一次有效
*  PendingIntent.FLAG_UPDATE_CURRENT:描述的Intent有 更新的时候需要用到这个flag去更新你的描述，否则组件在下次事件发生或时间到达的时候extras永远是第一次Intent的extras
*  PendingIntent.FLAG_ONE_SHOT:PendingIntent只能使用一次
*  PendingIntent.FLAG_NO_CREATE:利用FLAG_NO_CREAT获取的PendingIntent，若描述的Intent不存在则返回NULL值
