我正在尝试为我的课程设置闹钟。我需要在他们开始前1小时发出警报。所以我只想要
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:2012年4月23日23:37
Logcat是:

那么为什么它在logcat而不是今天的日期23中表示23. 03 .2012或25. 03 。2012. 04 0.2012?我一直在浪费我的时间,有人能告诉我正确设置闹钟的方法吗?
答案 0 :(得分:2)
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。
根据日历联机帮助页,JANUARY
的值为0,APRIL
的值为3.因此,如果您要打印通常打印的月份(4月= 4) ,然后只需在打印前的一个月添加一个。
