设置重复闹钟

Question

9我在做一个定时提醒你吃药的app，让用户给我频率和时间段，例如：

频率 = 8 小时经期 = 7 天

所以我会制作一个警报，在 7 天内每 8 小时触发一次。这是我现在的代码，但它没有按照我想要的方式工作......（它同时发送所有通知，所以在上面的例子中它一次发送 21 个通知，只需几秒钟在我运行代码之后，这意味着它不是发送第一个，而是发送所有代码）

private void makeAlarm(MedAlarm mAlarm) {

    String medName = mAlarm.getMedName();
    String medDescripcion = mAlarm.getMedDescription();
    String frequency = mAlarm.getMedIntervalHours();
    String duration = mAlarm.getMedIntervalDays();
    int lastitem = ((24 / Integer.parseInt(frequency)) * 
    Integer.parseInt(duration)) - 1;

    String alarmMsg = medName;

    for (int k = 0; k < ((24 / Integer.parseInt(frequency)) * 
         Integer.parseInt(duration)); k++) {// hours

        setAlarm(Integer.parseInt(frequency) * (k + 1), alarmMsg, k + "", 
         "0");
        Log.i("setAlarm", k + " - ");
        Log.i("duration", Integer.parseInt(frequency) * (k + 1) + "");

        if (k == lastitem) {
            setAlarm(Integer.parseInt(frequency) * (k + 1), alarmMsg, k + "", 
            "1");
        }
    }
}

/**
 * @param duration
 * @param name
 * @param id
 * @param lastitem 0 normal item, 1 last item
 */
private void setAlarm(int duration, String name, String id, String lastitem) 
{

    Calendar calendar = Calendar.getInstance();
    calendar.setTimeInMillis(System.currentTimeMillis());

    Intent alertIntent = new Intent(this, AlertReceiver.class);
    alertIntent.putExtra("message", name);
    alertIntent.putExtra("id", id);
    alertIntent.putExtra("lastitem", lastitem);
    PendingIntent pi = PendingIntent.getBroadcast(this, duration++, 
    alertIntent, PendingIntent.FLAG_UPDATE_CURRENT);

    int alarmType = AlarmManager.ELAPSED_REALTIME;
    final int FIFTEEN_SEC_MILLIS = 15000;
    final int HOURS_MILLIS = 3600000 * duration;
    AlarmManager alarmManager = (AlarmManager)
            this.getSystemService(this.ALARM_SERVICE);

    alarmManager.setRepeating(alarmType, SystemClock.elapsedRealtime() + 
    FIFTEEN_SEC_MILLIS,
            HOURS_MILLIS, pi);

    Log.i("intent sent", HOURS_MILLIS + " || ");
}

并且 class AlertReciver 是发送通知的那个。

如果你能帮我解决这个问题并告诉我我缺少什么，或者我是否应该以不同的方式解决这个问题。

谢谢。

使用 alarmManager.set() 而不是 alarmManager.setRepeating()。

更新您的 setAlarm() 方法如下：

private void setAlarm(int duration, String name, String id, String lastitem)
{
    Intent alertIntent = new Intent(this, AlertReceiver.class);
    alertIntent.putExtra("message", name);
    alertIntent.putExtra("id", id);
    alertIntent.putExtra("lastitem", lastitem);
    PendingIntent pi = PendingIntent.getBroadcast(this, duration++,
            alertIntent, PendingIntent.FLAG_UPDATE_CURRENT);

    int alarmType = AlarmManager.ELAPSED_REALTIME;
    final int FIFTEEN_SEC_MILLIS = 15000;
    final int HOURS_MILLIS = 3600000 * duration;
    AlarmManager alarmManager = (AlarmManager) this.getSystemService(this.ALARM_SERVICE);

    Calendar calendar = Calendar.getInstance();
    calendar.setTimeInMillis(System.currentTimeMillis() + HOURS_MILLIS);
    alarmManager.set(alarmType, calendar.getTimeInMillis() + FIFTEEN_SEC_MILLIS, pi);

    Log.i("intent sent", System.currentTimeMillis() + HOURS_MILLIS + " || ");
}
