android - 指定した時間にアラームを設定する方法

Question

@Override
public void onTimeSet(TimePicker view, int hourOfDay, int minute) {

    Calendar calNow = Calendar.getInstance();
    Calendar calSet = (Calendar) calNow.clone();

    calSet.set(Calendar.HOUR_OF_DAY, hourOfDay);
    calSet.set(Calendar.MINUTE, minute);
    calSet.set(Calendar.SECOND, 0);
    calSet.set(Calendar.MILLISECOND, 0);

    if(calSet.compareTo(calNow) <= 0){
        //Today Set time passed, count to tomorrow
        calSet.add(Calendar.DATE, 1);
    }

    setAlarm(calSet);
}};

private void setAlarm(Calendar targetCal){

    textAlarmPrompt.setText(
        "\n\n***\n"
        + "Alarm is set@ " + targetCal.getTime() + "\n"
        + "***\n");

    Intent intent = new Intent(getBaseContext(), AlarmReceiver.class);
    PendingIntent pendingIntent = PendingIntent.getBroadcast(getBaseContext(), RQS_1, intent, 0);
    AlarmManager alarmManager = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
    // alarmManager.set(AlarmManager.RTC_WAKEUP, targetCal.getTimeInMillis(), pendingIntent);
    alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, targetCal.getTimeInMillis(),AlarmManager.INTERVAL_DAY, pendingIntent);
}

この時間がすでに経過しているかどうかを確認する必要があります。そうでない場合、アラームは決して発生しません。
