Question

警报应每月重复一次，每月一次，每月一次，每月一次，等等就像我在10月31日发出警报一样，那么它应该在31个月的31个月内重复，因为我们每个月都没有相同的天数我在找出此警报的间隔时遇到问题，请帮我弄清楚这个INTERVAL_Value必须是什么，或者如何以另一种方式处理它

alarmMgr.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), AlarmManager.INTERVAL_Value, alarmIntent);

Answer 1

我们可以从源接收当前的月值，它是一个整数

if (currentMonth == Calendar.JANUARY || currentMonth == Calendar.MARCH || currentMonth == Calendar.MAY || currentMonth == Calendar.JULY 
            || currentMonth == Calendar.AUGUST || currentMonth == Calendar.OCTOBER || currentMonth == Calendar.DECEMBER){
    alarmMgr.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), AlarmManager.INTERVAL_DAY * 31, alarmIntent);
    }
    if (currentMonth == Calendar.APRIL || currentMonth == Calendar.JUNE || currentMonth == Calendar.SEPTEMBER 
            || currentMonth == Calendar.NOVEMBER){
        alarmMgr.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), AlarmManager.INTERVAL_DAY * 30, alarmIntent);
        }


    if  (currentMonth == Calendar.FEBRUARY){//for feburary month)
        GregorianCalendar cal = (GregorianCalendar) GregorianCalendar.getInstance();    
            if(cal.isLeapYear(year)){//for leap year feburary month  
                alarmMgr.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), AlarmManager.INTERVAL_DAY * 29, alarmIntent);
            }
            else{ //for non leap year feburary month
                alarmMgr.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), AlarmManager.INTERVAL_DAY * 28, alarmIntent);
            }
    }

Answer 2

您应该使用cal.getActualMaximum(Calendar.DAY_OF_MONTH));。这为您提供了每个月的最长日期，无论月份如何。

android重复警报，应该按月重复，并在每个月的同一天重播，等等
