AlarmManager

Question

我希望每年根据输入的日期（生日）显示通知。我有其他所有工作栏如何每年设置通知。正如您在下面看到的，我已将代码更改为 "HERE" 间隔所在的位置。有几天的间隔，我知道我可以将其乘以 365。但是如果是闰年会发生什么......

int REQUEST_CODE = 7;
Intent intent = new Intent(Activity2.this, Receiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(Activity2.this, REQUEST_CODE, intent, 0);
AlarmManager am = (AlarmManager) getSystemService(ALARM_SERVICE);
am.setRepeating(am.RTC_WAKEUP, System.currentTimeMillis(), HERE, pendingIntent);

Answer 1

1) 以 MM/DD/YY 格式保存日期。

2) 打开应用时（或不同时间）阅读这些日期

3) 为单个 day/today 自己设置警报。

此外，您还可以显示接下来的生日 week/month 等

Answer 2

您可以将'HERE'替换为一种方法，该方法确定从今天开始的下一个二月是否处于闰年，然后returns值365或366天（以毫秒为单位）你）基于这些检查。

private long millisUntilNextYear(){

    //Set days in a year for Leap and Regular
    final int daysInLeapYear = 366;
    final int daysInYear = 365;

    //Get calendar instance
    GregorianCalendar cal = (GregorianCalendar) GregorianCalendar.getInstance();

    //Get this year and next year
    int thisYear = cal.get(GregorianCalendar.YEAR);
    int nextYear = thisYear + 1;

    //Get today's month
    int thisMonth = cal.get(GregorianCalendar.MONTH);

    //Get today's date
    int dayOfMonth = cal.get(GregorianCalendar.DAY_OF_MONTH);

    //Is today before February? If so then the following February is in THIS year
    if (thisMonth < GregorianCalendar.FEBRUARY){

        //Check if THIS year is leapYear, and return correct days (converted to millis)
        return cal.isLeapYear(thisYear) ? daysToMillis(daysInLeapYear) : daysToMillis(daysInYear);
    }

    //Is today after February? If so then the following February is NEXT year
    else if (thisMonth > GregorianCalendar.FEBRUARY) {
        //Check if NEXT year is leapYear, and return correct days (converted to millis)
        return cal.isLeapYear(nextYear) ? daysToMillis(daysInLeapYear) : daysToMillis(daysInYear);
    }

    //Then today must be February.
    else {
        //Special case: today is February 29
        if (dayOfMonth == 29){
            return daysToMillis(daysInYear);
        } else {
            //Check if THIS year is leapYear, and return correct days (converted to millis)
            return cal.isLeapYear(thisYear) ? daysToMillis(daysInLeapYear) : daysToMillis(daysInYear);
        }
    }
}
