Question

我在每个星期一，每月1日和1月1日为setRepeating做一个函数，我每个星期一都这样做：

public class UserRoleCondition<T> : TypedQueryableStringOperatorCondition<T, IndexedContact> where T : VisitorRuleContext<IndexedContact>
{
    protected override Expression<Func<IndexedContact, bool>> GetResultPredicate(T ruleContext)
    {
        var userrole = this.Value ?? string.Empty;

        return
            this.GetCompareExpression(
                c => (string)c[(ObjectIndexerKey)"contact.profileproperties.userrole"], userrole);

    }
}

我的问题是我不知道每个月的每个月1日和1月1日我怎么办，因为每个月都有不同的天数。我需要点子。

Answer 1

我认为您可以通过以下内容完成此操作并每隔365天设置一次警报：

GregorianCalendar date = new GregorianCalendar();
date.set(Calendar.MONTH, Calendar.JANUARY);
date.set(Calendar.DAY_OF_MONTH, 1);
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, date.getTimeInMillis(), 365 * 24 * 60 * 60 * 1000, pendingintentResetAlarms);

date.set(Calendar.MONTH, Calendar.FEBRUARY);
date.set(Calendar.DAY_OF_MONTH, 1);  
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, date.getTimeInMillis(), 365 * 24 * 60 * 60 * 1000, pendingintentResetAlarms);
...

然而，有一个问题是一年有365天或366天。另一种解决方案可能是避免这种情况并执行以下操作：

alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, date.getTimeInMillis(), 24 * 60 * 60 * 1000, pendingintentResetAlarms);

它每天触发警报，在您的广播接收器中，您可以查看当天：

GregorianCalendar date = new GregorianCalendar();
if(date.get(Calendar.DAY_OF_MONTH) == 1)
   ....

实际上我认为第二种解决方案更好，更强大

    Bundle bundle = intent.getExtras();

        if (bRestAlarms) {
            //call your subbroutine here
            GregorianCalendar date = new GregorianCalendar();

                for(int i=0;i<6;i++) {
                    db.execSQL("UPDATE " + "SesionesSemana" + " SET " + columnas[i] + " = " + 0 + " WHERE " + "_id = 1");

                }
            }
            if(date.get(Calendar.DAY_OF_MONTH)==1 && date.get(Calendar.MONTH)==Calendar.JANUARY){
                //reseteo la tabla años
                for(int i=0;i<6;i++) {

                }
            }
            db.close();
        }
    }
