        int icon = R.drawable.ic_launcher;
        String tickerText = "Notification";
        long when = System.currentTimeMillis();

        Notification notification = new Notification(icon, tickerText, when);
        notification.number++;

        //设置展开通知的内容
        Context context = getApplicationContext();
        String expandedText = "Extended status text";
        String expandedTitle = "Notification Title";

        //当单击展开的文本时，用于启动一个活动的意图
        Intent intent = new Intent(this, MyActivity.class);
        PendingIntent launchIntent = PendingIntent.getActivity(context, 0, intent, 0);
        notification.setLatestEventInfo(context, expandedText, expandedText, launchIntent);

        //若要定制布局(若手动设置contentView时，必须同时设置contentIntent)
        notification.contentView = new RemoteViews(this.getPackageName(), R.layout.my_status_window_layout);
        notification.contentIntent = launchIntent;

        //修改通知中的视图
        notification.contentView.setImageViewResource(R.id.status_icon, R.drawable.ic_launcher);//将后者搬到前者这个id的视图上
        notification.contentView.setTextViewText(R.id.status_text, "Current Progress");
        notification.contentView.setProgressBar(R.id.status_progress, 100, 50, false);

        //触发通知
        int notificationRef = 1;
        notificationManager.notify(notificationRef, notification);

        //消除通知
        notificationManager.cancel(notificationRef);

        notification.defaults = Notification.DEFAULT_SOUND | Notification.DEFAULT_VIBRATE; //设置上默认的声音和震动

        //自定义通知声音

        notification.sound = ringURI;

        //自定义通知震动,需添加一个permission <uses-permission android:name="android.permission.VIBRATE" />
        long[] vibrate = new long[] {1000,1000,1000,1000,1000};//一个值震动多久，下一个值暂定多久，这里持续了5秒
        notification.vibrate = vibrate;

        //自定义通知闪屏
        notification.ledARGB = Color.RED;
        notification.ledOffMS = 0;//设置频率
        notification.ledOnMS = 1; //若OnMS也是0，则将灯关闭
        notification.flags = notification.flags | Notification.FLAG_SHOW_LIGHTS;

        //持续的通知
        notification.flags = notification.flags | Notification.FLAG_ONGOING_EVENT;//正在进行的事件
        //连续的通知
        notification.flags = notification.flags | Notification.FLAG_INSISTENT;//一直重复音频震动闪烁直到被取消

//        RTC_WAKEUP指定时间唤醒并触发意图；
//        RTC指定时间触发意图但不唤醒设备；
//        ELAPSED_REALTIME设备启动后经过的时间触发待处理的意图，但不唤醒设备；
