Java 通过AlarmManager取消通知时出现问题,java,android,Java,Android,我有一个由AlarmManager触发的通知。这是我的代码： notification = new NotificationCompat.Builder(getActivity()); AlarmManager alarmManager = (AlarmManager) getActivity().getSystemService(Context.ALARM_SERVICE); Intent notificationIntent = new Intent("andro

我有一个由

AlarmManager

触发的

通知。这是我的代码：
    notification = new NotificationCompat.Builder(getActivity());

    AlarmManager alarmManager = (AlarmManager) getActivity().getSystemService(Context.ALARM_SERVICE);

    Intent notificationIntent = new Intent("android.media.action.DISPLAY_NOTIFICATION");

    notificationIntent.addCategory("android.intent.category.DEFAULT");

    PendingIntent broadcast = PendingIntent.getBroadcast(getContext(), 5000, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);

    alarmManager.setExact(AlarmManager.RTC_WAKEUP, 10000, broadcast);

    alarmManager.cancel(broadcast);
    // here am trying to cancel the notification with PendingIntent but its not working 

编辑：
我所说的“工作”是指不取消本应使用的通知
PendingIntent.getBroadcast(getContext(), 5000, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT).cancel();

代替alarmManager。取消（广播）
