每次打开app都会响我搞不懂为什么每次打开app我的notification设置为响alarmgoes取消。我只在特定的日期和时间设置日历。我的闹钟不仅没有在日历上指示的时间和星期几响起。我的闹钟需要维修吗？我试图确保即使应用程序关闭它也会关闭。下面的代码(MyService)在MainActivityonCreate()中被调用。[服务]publicclassMyService:Service{//constintNOTIFICATION_ID=9000;publicoverrideStartCommandResultOnStartCommand(Intentintent,StartCommandFlagsflags,intstartId){SetAlarm();返回StartCommandResult.Sticky；}privatevoidSetAlarm(){//设置日历Java.Util.Calendarcalendar=Java.Util.Calendar.Instance;calendar.Set(Java.Util.CalendarField.DayOfWeek,1);calendar.Set(Java.Util.CalendarField.HourOfDay,02);calendar.Set(Java.Util.CalendarField.Minute,15);AlarmManager管理器=(AlarmManager)GetSystemService(Context.AlarmService);意图经理意图；待定意图managerIntent=newIntent(this,typeof(AlarmNotificationReceiver));//pendingIntent=PendingIntent.GetBroadcast(this,0,managerIntent,0);pendingIntent=PendingIntent.GetBroadcast(this,0,managerIntent,PendingIntentFlags.UpdateCurrent);//manager.SetRepeating(AlarmType.RtcWakeup,SystemClock.ElapsedRealtime()+3000,60+1000,待定意图）；//manager.SetRepeating(AlarmType.ElapsedRealtimeWakeup,SystemClock.ElapsedRealtime()+AlarmManager.IntervalHalfHour,AlarmManager.IntervalHalfHour,pendingIntent);//manager.SetRepeating(AlarmType.RtcWakeup,calendar.TimeInMillis,AlarmManager.IntervalHalfHour,pendingIntent);manager.SetRepeating(AlarmType.RtcWakeup,calendar.TimeInMillis,604800,pendingIntent);}[BroadcastReceiver(Enabled=true)]publicclassAlarmNotificationReceiver:BroadcastReceiver{publicoverridevoidOnReceive(Contextcontext,Intentintent){NotificationCompat.Builderbuilder=newNotificationCompat.Builder(context);builder.SetAutoCancel(true).SetDefaults((int)NotificationDefaults.All).SetSmallIcon(Resource.Drawable.Icon).SetContentTitle("ComicPullList").SetStyle(newNotificationCompat.BigTextStyle().BigText("新漫画有这周出来了！检查你的列表，如果需要的话拉漫画。”））.SetContentText（“新漫画已经出来了星期！检查你的列表，如果需要的话拉漫画。”);NotificationManagermanager=(NotificationManager)context.GetSystemService(Context.NotificationService);manager.Notify(1,builder.Build());}}}我添加的新代码如下：AlarmManagermanager=(AlarmManager)GetSystemService(Context.AlarmService);//设置日历Java.Util.Calendarcalendar=Java.Util.Calendar.Instance;if(calendar.Get(Java.Util.CalendarField.DayOfWeek)==Java.Util.Calendar.Wednesday){calendar.Add(Java.Util.CalendarField.Date,4);}while(calendar.Get(Java.Util.CalendarField.DayOfWeek)!=Java.Util.Calendar.Wednesday){日历。添加(Java.Util.CalendarField.Date,4);}//calendar.Set(Java.Util.CalendarField.DayOfWeek,1);calendar.Set(Java.Util.CalendarField.HourOfDay,15);calendar.Set(Java.Util.CalendarField.Minute,30);意图managerIntent;PendingIntentpendingIntent;managerIntent=newIntent(this,typeof(AlarmNotificationReceiver));//pendingIntent=PendingIntent.Get广播（这，0，managerIntent，0）；pendingIntent=PendingIntent.GetBroadcast(this,0,managerIntent,PendingIntentFlags.UpdateCurrent);//manager.SetRepeating(AlarmType.RtcWakeup,SystemClock.ElapsedRealtime()+3000,60+1000,pendingIntent);//manager.SetRepeating(AlarmType.ElapsedRealtimeWakeup,SystemClock.ElapsedRealtime()+AlarmManager.IntervalHalfHour,AlarmManager.IntervalHalfHour,pendingIntent);//manager.SetRepeating(AlarmType.RtcWakeup,calendar.TimeInMillis,AlarmManager.Intervaling);manager.SetRepeating(AlarmType.RtcWakeup,calendar.TimeInMillis,1000*60*60*24*7,pendingIntent);您正在设置过去的第一个警报如果您指定的触发时间是过去，警报将立即触发。您需要将日期设置为下一个星期日。以上是C#学习教程：每次打开应用时闹钟都会关闭所有分享的内容。如果对大家有用，需要进一步了解C#学习教程，希望大家多多关注——例子：using(AlarmManagermanager=(AlarmManager)GetSystemService(AlarmService))using(varcalendar=Calendar.Instance){如果(calendar.Get(CalendarField.DayOfWeek)==Calendar.Sunday)calendar.Add(CalendarField.Date,1);while(calendar.Get(CalendarField.DayOfWeek)!=Calendar.Sunday)calendar.Add(CalendarField.Date,1);calendar.Set(CalendarField.HourOfDay,02);calendar.Set(CalendarField.Minute,15);Log.Debug("SO",$"当前日期是：{Calendar.Instance.Time.ToString()}");Log.Debug("SO",$"Alarmwillfireat{calendar.Time.ToString()}");varmanagerIntent=newIntent(this,typeof(MainActivity));varpendingIntent=PendingIntent.GetBroadcast(this,0,managerIntent,PendingIntentFlags.UpdateCurrent);manager.SetRepeating(AlarmType.RtcWakeup,calendar.TimeInMillis,1000*60*60*24*7,pendingIntent);}输出：[SO]当前日期是：2017年8月12日星期六23:01:11PDT[SO]警报将在：SunAug1302:15:11PDT2017本文收集自网络，不代表立场。如涉及侵权，请点击右侧联系管理员删除。如需转载请注明出处：
