Notification notification = new Notification();
notification.icon=iconId;
notification.tickerText=tickerText;
long time = System.currentTimeMillis();
Date d = new Date(time);
notification.when=System.currentTimeMillis()+3600*10000000;
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, getIntent(), 0);
notification.setLatestEventInfo(this, contentTitle, contentText, pendingIntent);
//5步:使用notificationManager对象的notify方法 显示Notification消息 需要制定 Notification的标识
notificationManager.notify(notiId, notification);
Notification的when参数不管设置成多少都是马上就通知比如上面的代码也是马上通知,怎么才能设置通知时间
