我希望能够发出通知，以提醒用户有关计时器已结束的信息，但是，当您单击通知时，我不希望有任何意图。

我已经尝试将null传递给意图

String ns = Context.NOTIFICATION_SERVICE;
NotificationManager mNotificationManager = (NotificationManager) context.getSystemService(ns);

int icon = R.drawable.icon;
CharSequence tickerText = "Hello";
long when = System.currentTimeMillis();

Notification notification = new Notification(icon, tickerText, when);

CharSequence contentTitle = "My notification";
CharSequence contentText = "Hello World!";

notification.setLatestEventInfo(context, contentTitle, contentText, null);
mNotificationManager.notify(HELLO_ID, notification);
