Java Alarmmanager在单击通知后不取消

我正在开发带有alarmmanager和服务的应用程序，在某些情况下我无法取消通知。我用的是碎片

我的应用程序每“x”分钟发送两次通知。我有一个按钮启动服务，另一个按钮停止服务。当我启动服务时，会触发通知，当我按下停止按钮时，通知会正常工作。但当我启动服务并退出应用程序时，通知会正常触发，但当我单击通知时，应用程序会打开，然后我按下停止按钮，但通知从未停止，通知会继续触发

调用AlarmManager.cancel（PendingEvent）的函数位于同一片段中。。（MainFragment.class，它是第一个片段）

main.class

    intent = new Intent(getContext(), TimeAlarm.class);
    intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP | Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_LAUNCHED_FROM_HISTORY);
    intent.setAction(Long.toString(System.currentTimeMillis()));
    pendingIntent = PendingIntent.getBroadcast(mContext, 0,
            intent, PendingIntent.FLAG_UPDATE_CURRENT);

    am.setRepeating(AlarmManager.ELAPSED_REALTIME_WAKEUP,
                SystemClock.elapsedRealtime() + 15000,
                15000,
                pendingIntent);

    intent2 = new Intent(getContext(), TimeAlarm2.class);
    intent2.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP | Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_LAUNCHED_FROM_HISTORY);
    intent2.setAction(Long.toString(System.currentTimeMillis()));
    pendingIntent2 = PendingIntent.getBroadcast(getContext(), 1,
            intent2, PendingIntent.FLAG_UPDATE_CURRENT);

    am.setRepeating(AlarmManager.ELAPSED_REALTIME_WAKEUP,
                        SystemClock.elapsedRealtime() + 15000,
                        15000,
                        pendingIntent2);

TimeAlarm.class，它扩展了BroadcastReceiver

NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(context)
                .setSmallIcon(R.drawable.icon)
                .setContentTitle("...")
                .setContentText("...");

 Intent resultIntent = new Intent(context, MainActivity.class);
        TaskStackBuilder stackBuilder = TaskStackBuilder.create(context);
        stackBuilder.addParentStack(MainActivity.class);
        stackBuilder.addNextIntent(resultIntent);
        PendingIntent resultPendingIntent =
                stackBuilder.getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT);
        mBuilder.setContentIntent(resultPendingIntent);

        mBuilder.setAutoCancel(true);

        mBuilder.build().flags |= Notification.FLAG_AUTO_CANCEL | Notification.FLAG_ONGOING_EVENT;

        NotificationManager mNotificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
        mNotificationManager.notify(0, mBuilder.build());

NotificationCompat.Builder mBuilder2 = new NotificationCompat.Builder(context)
                .setSmallIcon(R.drawable.icon2)
                .setContentTitle("..")
                .setContentText("..");

        Intent resultIntent = new Intent(context, MainActivity.class);
        TaskStackBuilder stackBuilder = TaskStackBuilder.create(context);
        stackBuilder.addParentStack(MainActivity.class);
        stackBuilder.addNextIntent(resultIntent);
        PendingIntent resultPendingIntent =
                stackBuilder.getPendingIntent(1, PendingIntent.FLAG_UPDATE_CURRENT);

        mBuilder2.setContentIntent(resultPendingIntent);

        mBuilder2.setAutoCancel(true);

        mBuilder2.build().flags |= Notification.FLAG_AUTO_CANCEL | Notification.FLAG_ONGOING_EVENT;
        NotificationManager mNotificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
        mNotificationManager.notify(1, mBuilder2.build());

TimeAlarm2.class，它扩展了BroadcastReceiver

NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(context)
                .setSmallIcon(R.drawable.icon)
                .setContentTitle("...")
                .setContentText("...");

 Intent resultIntent = new Intent(context, MainActivity.class);
        TaskStackBuilder stackBuilder = TaskStackBuilder.create(context);
        stackBuilder.addParentStack(MainActivity.class);
        stackBuilder.addNextIntent(resultIntent);
        PendingIntent resultPendingIntent =
                stackBuilder.getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT);
        mBuilder.setContentIntent(resultPendingIntent);

        mBuilder.setAutoCancel(true);

        mBuilder.build().flags |= Notification.FLAG_AUTO_CANCEL | Notification.FLAG_ONGOING_EVENT;

        NotificationManager mNotificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
        mNotificationManager.notify(0, mBuilder.build());

NotificationCompat.Builder mBuilder2 = new NotificationCompat.Builder(context)
                .setSmallIcon(R.drawable.icon2)
                .setContentTitle("..")
                .setContentText("..");

        Intent resultIntent = new Intent(context, MainActivity.class);
        TaskStackBuilder stackBuilder = TaskStackBuilder.create(context);
        stackBuilder.addParentStack(MainActivity.class);
        stackBuilder.addNextIntent(resultIntent);
        PendingIntent resultPendingIntent =
                stackBuilder.getPendingIntent(1, PendingIntent.FLAG_UPDATE_CURRENT);

        mBuilder2.setContentIntent(resultPendingIntent);

        mBuilder2.setAutoCancel(true);

        mBuilder2.build().flags |= Notification.FLAG_AUTO_CANCEL | Notification.FLAG_ONGOING_EVENT;
        NotificationManager mNotificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
        mNotificationManager.notify(1, mBuilder2.build());

谢谢并致以最良好的问候

试试这个，如果出现错误，告诉我会发生什么

为此，您需要在“停止”按钮上销毁服务，然后单击“开始”按钮再次启动服务。

好的。我建议您在AlarmManager上调用

cancel（）

，使用与

setRepeating（）

方法相同的挂起内容

在这里，您可以取消两个等效的挂起帐篷

am.cancel(pendingIntent);

及

希望它能对您有所帮助。

从两个意图中删除这些行，然后重试

intent2.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP |
Intent.FLAG_ACTIVITY_SINGLE_TOP | Intent.FLAG_ACTIVITY_NEW_TASK |
Intent.FLAG_ACTIVITY_LAUNCHED_FROM_HISTORY);
intent2.setAction(Long.toString(System.currentTimeMillis()));

它对我有效

这可能有助于您解决此问题，但我不确定。Ref:@Sabari谢谢，我通过混合代码解决了这个问题。但现在，问题是当我手动关闭应用程序时。。通知将继续触发，当我再次打开应用程序并按下停止按钮时，报警管理器不会被取消。您是否可以完全共享停止按钮单击事件？@Sabari在cancelAlarm（）函数中，我刚刚有am.cancel（PendingEvent）；上午10点取消（暂停2）；PendingEvent是全局的，在onCreate方法中定义。我对您的代码有点困惑。您是否在“开始”点击事件中调用此“am.setRepeating”并初始化“pendingent”？
