android - 我无法设置闹钟日历

Question

我正在尝试为我的类(class)设置闹钟。我需要在他们开始前 1 小时拉响警报。所以我只想

• 获取一年中的第几周
• 查看周数(循环 ...51,52)
  • 浏览类(class)(循环...n)
    • 为这门课设置星期几
    • 将一天中的时间设置为上课前一小时
    • 将分钟设置为 00
    • 使用这个日历实例设置闹钟
  • 循环结束(类)
  • 将周设置为从当前周算起的一周

Calendar cal = Calendar.getInstance();
cal.setTimeInMillis(System.currentTimeMillis());
for (int i = cal.get(Calendar.WEEK_OF_YEAR); i <= 52; i++) {
    for (Dersler d : dersProgrami) {
        alarm = new DersAlarmi(String.valueOf(d.getBaslangicS()) + "00", d.getDersAdi(), d.getDerslik());
        cal.set(Calendar.DAY_OF_WEEK, d.getDayOfClass()+1);
        cal.set(Calendar.MINUTE, 00);
        cal.set(Calendar.HOUR_OF_DAY, d.getStartHour());
        cal.add(Calendar.HOUR_OF_DAY, -1);
        Log.i("ALARM KURULDU",
            String.valueOf(i) + String.valueOf(cal.get(Calendar.DAY_OF_MONTH))+"."+String.valueOf(cal.get(Calendar.MONTH))+"."+String.valueOf(cal.get(Calendar.YEAR))+" "+String.valueOf(cal.get(Calendar.HOUR_OF_DAY))+":"+String.valueOf(cal.get(Calendar.MINUTE))+" Ders:" + d.getDersAdi()
                + " Hafta:"
                + cal.get(Calendar.WEEK_OF_YEAR) + " Gün:"
                + cal.get(Calendar.DAY_OF_WEEK) + " Saat:"
                + cal.get(Calendar.HOUR_OF_DAY));
            alarmManager.set(AlarmManager.RTC_WAKEUP,
                cal.getTimeInMillis(), pendingIntent);
        dersAlarmlari.add(alarm);
    }
    cal.set(Calendar.WEEK_OF_YEAR, cal.get(Calendar.WEEK_OF_YEAR)+1);
}

当前日期时间是:23.04.2012 23:37

Logcat 是:

04-23 23:23:10.835: I/ALARM KURULDU(16380): 17 25.3.2012 14:0 Ders:DATA MINING Hafta:17 Gün:4 Saat:14

...

那么为什么它在 logcat 中说的是 23.03.2012 或 25.03.2012 而不是今天的日期 23.04.2012？我一直在为此浪费时间，谁能告诉我设置闹钟的正确方法吗？

Answer 1

您正在使用它来打印月份:cal.get(Calendar.MONTH))

然而，返回的月份看起来是零索引的。

根据日历联机帮助页，JANUARY 的值为 0，而 APRIL 的值为 3。因此，如果您想像通常那样打印月份打印(4 月 = 4)，然后只需在打印前的月份加一。
