我正在使用倒数计时器类,并且在该类的onfinish()状态下,我正在创建通知。这是Onfinish方法的代码:
public void onFinish() {
notificate();
Log.i("Aler Resume", "Finished");
remtime.setText("0 : 00 : 00");
textCondition.setText(getString(R.string.BuddyAlertExpired));
}
在我写的notificate()方法中:
private void notificate() {
NotificationManager notifManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
Notification note = new Notification(R.drawable.ic_launcher, "New E-mail", System.currentTimeMillis());
PendingIntent intent = PendingIntent.getActivity(this, 0, new Intent(this, AlertResume.class), 0);
note.setLatestEventInfo(this, "Buddy Alert", getString(R.string.BuddyAlertExpired), intent);
note.defaults= Notification.DEFAULT_VIBRATE;
note.defaults=Notification.DEFAULT_SOUND;
notifManager.notify(NOTIF_ID, note);
}
当我保持应用程序打开时,它工作正常。但是当我从应用程序返回时,调用onfinish方法并且我可以正确地看到日志但是notofication方法不起作用并且不显示任何通知。有什么错吗?

当你离开应用程序时,可能会发生Android认为你的进程运行CountDown Timer作为垃圾邮件或额外而非意图。并完成它...(就像它认为你忘了关闭让我关闭)
所以最好使用AlarmManager来完成上述内容,例如设置PendingIntent - Notification,在你开始倒计时器的时候,也可以通过使用ALARM MANAGER的意图来设置通知。
nm = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
Notification notification = new Notification(R.drawable.icon, "Test", System.currentTimeMillis());
Intent intentTL = new Intent(context, MainActivity.class);
notification.setLatestEventInfo(context, "Test", "Do something!",
PendingIntent.getActivity(context, 0, intentTL,
PendingIntent.FLAG_CANCEL_CURRENT));
notification.flags = Notification.DEFAULT_LIGHTS | Notification.FLAG_AUTO_CANCEL;
nm.notify(1, notification);
AlarmManager am = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0,
intent, PendingIntent.FLAG_CANCEL_CURRENT);
am.set(AlarmManager.RTC_WAKEUP, System.currentTimeMillis() + 10000, pendingIntent);
