【问题描述】：

我一直在尝试为特定日期设置 AlarmManager，但它根本不起作用！当我只使用时间时，它工作正常。代码如下：

SharedPreferences prefs = PreferenceManager
                    .getDefaultSharedPreferences(this);
            String getEventTime = prefs.getString("EventSTime", "");
            String getEventDate = prefs.getString("EventDate", "");
            Toast.makeText(this, getEventTime + " " + getEventDate,
                    Toast.LENGTH_LONG).show();
            String temp = "", temp2 = "";
            DateFormat dateformat = new SimpleDateFormat("HH:mm");
            DateFormat dateformatDate = new SimpleDateFormat("dd-MM-yyyy");
            try {
                temp = dateformat.format(dateformat.parse(getEventTime));
                temp2 = dateformatDate.format(dateformatDate
                        .parse(getEventDate));
                Toast.makeText(this, temp + " " + temp2, Toast.LENGTH_LONG)
                        .show();

            } catch (ParseException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            String getEventTimeSubStringHour = temp.substring(0, 2);
            String getEventTimeSubStringMinute = temp.substring(3, 5);
            String getEventDateSubStringDay = temp2.substring(0, 2);
            String getEventDateSubStringMonth = temp2.substring(3, 5);
            String getEventDateSubStringYear = temp2.substring(6, 10);
            Toast.makeText(
                    this,
                    getEventTimeSubStringHour + " "
                            + getEventTimeSubStringMinute + " "
                            + getEventDateSubStringDay + " "
                            + getEventDateSubStringMonth + " "
                            + getEventDateSubStringYear, Toast.LENGTH_LONG)
                    .show();
            hourOfDay = Integer.parseInt(getEventTimeSubStringHour);
            minute = Integer.parseInt(getEventTimeSubStringMinute);
            day = Integer.parseInt(getEventDateSubStringDay);
            month = Integer.parseInt(getEventDateSubStringMonth);
            year = Integer.parseInt(getEventDateSubStringYear);
            int second = 0;
//          calendar.setTimeInMillis(System.currentTimeMillis());
//          calendar.clear();
            //calendar.set(year, month, day);
            calendar.set(Calendar.YEAR, year);
            calendar.set(Calendar.MONTH, month);
            calendar.set(Calendar.DAY_OF_MONTH, day);
            calendar.set(Calendar.HOUR_OF_DAY, hourOfDay);
            calendar.set(Calendar.MINUTE, minute);
            calendar.set(Calendar.SECOND, second);


            Intent intent = new Intent(MessageService.this,
                    ServiceManager.class);
            PendingIntent callToServiceManager = PendingIntent.getService(
                    MessageService.this, 2, intent, 0);
            AlarmManager alarmToCallServiceManager = (AlarmManager) getSystemService(ALARM_SERVICE);
            alarmToCallServiceManager.set(AlarmManager.RTC_WAKEUP,
                    calendar.getTimeInMillis(), callToServiceManager);

即使在使用calendar.set(year, month, day, hourOfDay, minute, second) 之后也没有发生任何事情。请帮忙！谢谢！

【问题讨论】：

我也有同样的问题，很烦人。如果我删除与 YEAR 和 MONTH 相关的任何内容，我会在我的系统上注意到它有效。
@EugenevanderMerwe 那么你找到解决方案了吗？
原来我将六月存储为第6个月。实际上它应该存储为5，月份从0开始计数。
@EugenevanderMerwe 哦，那我应该试试。 :)

【解决方案1】：

感谢 Eugen 指导我。原来是价值的问题，事实上，我将六月存储为第 7 个月而不是第 6 个月。我在这个月里加了 1，但它出现了问题。现在我已经修复了它，它现在工作正常。
