java - 单击通知后 Alarmmanager 未取消

Question

我正在开发一个带有 alarmmanager 和服务的应用程序，在某些情况下我无法取消通知。我正在使用 fragment 。

我的应用每隔“x”分钟发送两个通知。我有一个启动服务的按钮和另一个停止服务的按钮。当我启动服务时，会触发通知，当我按下停止按钮时，它会正常工作。但是当我启动服务并退出应用程序时，通知会正常触发，但是当我单击通知时，应用程序会打开，然后我按下停止按钮但通知不会停止，通知会继续被触发。

我调用 alarmanager.cancel(pendingintent) 的函数在同一个 fragment 中..(MainFragment.class 是第一个 fragment )。

MainFragment.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);

扩展 BroadcastReceiver 的 TimeAlarm.class

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());

扩展 BroadcastReceiver 的 TimeAlarm2.class

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());

谢谢并致以最诚挚的问候!

Answer 1

从两个 Intent 中删除这些行并重试。

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()));

对我有用
