Question

我试图创建一个警报，触发按钮点击，并将在早上6:00重复。我做的第一个工作正常，但是当我添加另一个重复警报时，它同时触发了上一个警报。所以我的问题是如何才能使多重警报正常工作？

重复闹钟的代码

 public void setAlarmRepeating()
    {
        AlarmManager dog=(AlarmManager)this.getSystemService(Context.ALARM_SERVICE);
        Intent alarm_dog=new Intent(this,Dog_alarm.class);
        PendingIntent pi1 = PendingIntent.getBroadcast(this, 100,alarm_dog, PendingIntent.FLAG_UPDATE_CURRENT);
        Calendar calendar = Calendar.getInstance();
        calendar.set(Calendar.HOUR_OF_DAY, 6);
        calendar.set(Calendar.MINUTE,0);
        calendar.set(Calendar.SECOND, 00);
        dog.setRepeating(AlarmManager.RTC_WAKEUP,calendar.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pi1);


        AlarmManager dog1=(AlarmManager)this.getSystemService(Context.ALARM_SERVICE);
        Intent alarm_dog1=new Intent(this,Dog_alarm.class);
        PendingIntent pi2 = PendingIntent.getBroadcast(this, 200,alarm_dog1, PendingIntent.FLAG_UPDATE_CURRENT);
        Calendar calendar1 = Calendar.getInstance();
        calendar1.set(Calendar.HOUR_OF_DAY, 7);
        calendar1.set(Calendar.MINUTE,0);
        calendar1.set(Calendar.SECOND, 00);
        dog1.setRepeating(AlarmManager.RTC_WAKEUP,calendar1.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pi2);

    }

这适用于BroadcastReciever

 public class MorningAlarm extends BroadcastReceiver{
    @Override
    public void onReceive(Context context, Intent intent) {
        NotificationManager notificationManager1=(NotificationManager)context.getSystemService(context.NOTIFICATION_SERVICE);
        Intent dog_intent1=new Intent(context,HomeActivity.class);
        dog_intent1.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        PendingIntent dog_pending1=PendingIntent.getActivity(context, 100,dog_intent1, PendingIntent.FLAG_UPDATE_CURRENT);

        NotificationCompat.Builder builder1=new NotificationCompat.Builder(context)
                .setContentIntent(dog_pending1)
                .setSmallIcon(android.R.drawable.ic_dialog_alert)
                .setContentTitle("Pet Guide 101")
                .setContentText("Time to feed your dog")
                .setAutoCancel(true);
        notificationManager1.notify(100,builder1.build());



        NotificationManager notificationManager2=(NotificationManager)context.getSystemService(context.NOTIFICATION_SERVICE);
        Intent dog_intent2=new Intent(context,HomeActivity.class);
        dog_intent2.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        PendingIntent dog_pending2=PendingIntent.getActivity(context, 200,dog_intent2, PendingIntent.FLAG_UPDATE_CURRENT);

        NotificationCompat.Builder builder2=new NotificationCompat.Builder(context)
                .setContentIntent(dog_pending2)
                .setSmallIcon(android.R.drawable.ic_dialog_alert)
                .setContentTitle("Pet Guide 101")
                .setContentText("Time to walk your dog")
                .setAutoCancel(true);
        notificationManager2.notify(200,builder2.build());
    }
}

Answer 1

当您使用PendingIntent.FLAG_UPDATE_CURRENT标记当前PendingIntent更新新的附加内容并且未创建新的PendingIntent时。

您必须为每个闹钟创建新的PendingIntent。

使用：

PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, intent, 0);

请记住取消闹钟，您必须重启设备或卸载应用

Answer 2

我认为这是因为您的警报管理员没有将您的任务视为时间紧迫的

您需要使用setInexactRepeating()而不是setRepeating()函数。

希望它能工作。
