AlarmManager 没有按正确的时间表工作

Question

在我的应用程序中，我有 18 Checkboxes，如果用户检查它，AlarmManager 将在 CheckBox 指示的时间开始通知。我用一个警报器测试了 AlarmManager，它工作正常。

但是当我添加所有计划时，它无法正常工作并且 AlarmManager 在偶然的时间开始通知，通常是在我关闭应用程序时。

MainFragment.class，在方法 onCreate 中。这是为了保存复选框已标记并调用将创建 AlarmManager 的方法。

MainFragment.class,这是创建Alarm的方法

public void startAlarm(int eventID) {
        int[] HOUR_ARRAY =      {7, 20, 7,12,17 ,8,16, 8, 9,21, 9,19,12,13,13,14,15,15};
        int[] MINUTES_ARRAY =   {55,55,55,55,55,25,25,55,55,55,55,25,50,25,55,55,25,55};
        String[] NOTIFICATION_TITLES = {"Ocleera Rift", "Ocleera Rift", "Mistmerrow Conflict", "Mistmerrow Conflict",
        "Mistmerrow Conflict", "Freedich Gold Trader", "Freedich Gold Trader", "Nation Construction Quests", "Diamond Shores",
        "Diamond Shores", "Battle of the Golden Plains", "Battle of the Golden Plains", "Karkasse Ridgelands", "Kraken",
        "The Mirage Isle Fish Fest", "Red Dragon", "Abyssal Attack", "Lusca Awakening"};

        String notificationTitle = getString(R.string.contentTitle);
        String notificationText = NOTIFICATION_TITLES[eventID] + getString(R.string.contentNotificationText);

        Calendar calendar = Calendar.getInstance();
        Log.d("HOUR-BEFORE-SET", String.valueOf(calendar.get(Calendar.HOUR_OF_DAY)) + String.valueOf(calendar.get(Calendar.MINUTE)));
        calendar.set(Calendar.HOUR_OF_DAY, HOUR_ARRAY[eventID]);
        calendar.set(Calendar.MINUTE, MINUTES_ARRAY[eventID]);
        Log.d("HOUR-AFTER-SET", String.valueOf(calendar.get(Calendar.HOUR_OF_DAY)) + String.valueOf(calendar.get(Calendar.MINUTE)));

        Intent intent = new Intent(getActivity().getApplicationContext(), AlarmReceiver.class);
        intent.putExtra("contentTitle", notificationTitle);
        intent.putExtra("contentText", notificationText);

        PendingIntent pendingIntent = PendingIntent.getBroadcast(getActivity().getApplicationContext(), eventID, intent, PendingIntent.FLAG_UPDATE_CURRENT);

        AlarmManager alarmManager = (AlarmManager) getActivity().getSystemService(Context.ALARM_SERVICE);
        alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pendingIntent);
    }

AlarmReceiver.class，这是我的BroadcastReceiver

public class AlarmReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {

        NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context
        .NOTIFICATION_SERVICE);

        Intent repeatingIntent = new Intent(context,RepeatingActivity.class);
        repeatingIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

        PendingIntent pendingIntent = PendingIntent.getActivity(context,100,repeatingIntent,
                PendingIntent.FLAG_UPDATE_CURRENT);

        String contentTitle = intent.getStringExtra("contentTitle");
        String contentText = intent.getStringExtra("contentText");

        NotificationCompat.Builder builder = new NotificationCompat.Builder(context)
                .setContentIntent(pendingIntent)
                .setSmallIcon(R.drawable.icon_notification)
                .setLargeIcon(BitmapFactory.decodeResource(context.getResources(), R.drawable.icon_notification))
                .setContentTitle(contentTitle)
                .setContentText(contentText)
                .setSound(RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION))
                .setVibrate(new long[]{800,500,600,300})
                .setLights(Color.GREEN, 500, 500)
                .setAutoCancel(true);

        notificationManager.notify(100,builder.build());

        // Light up the screen
        PowerManager pm = (PowerManager)context.getSystemService(Context.POWER_SERVICE);
        boolean isScreenOn = false;
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT_WATCH) {
            isScreenOn = pm.isInteractive();
        }
        else if(Build.VERSION.SDK_INT < Build.VERSION_CODES.KITKAT_WATCH){
            isScreenOn = pm.isScreenOn();
        }

        if(isScreenOn==false)
        {
            PowerManager.WakeLock wl = pm.newWakeLock(PowerManager.FULL_WAKE_LOCK |PowerManager.ACQUIRE_CAUSES_WAKEUP |PowerManager.ON_AFTER_RELEASE,"MyLock");
            wl.acquire(10000);
            PowerManager.WakeLock wl_cpu = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK,"MyCpuLock");

            wl_cpu.acquire(10000);
        }
    }

}

Answer 1

AlarmManager 文档说 setRepeating:

If the stated trigger time is in the past, the alarm will be triggered immediately, with an alarm count depending on how far in the past the trigger time is relative to the repeat interval.

我的闹钟启动时间错误，因为设置的时间已经过去了。与多次报警无关

我所做的调整是将已经过去的警报设置为在第二天开始。

Calendar actualTime = Calendar.getInstance();
if(calendar.getTimeInMillis() < actualTime.getTimeInMillis()) {
    calendar.set(Calendar.DAY_OF_MONTH, 1);
}

我刚刚将它添加到我的代码中。
