Question

在我的应用程序中，我设置了许多警报通知。所有人都在不同的日期，但同一时间。我在切换按钮的帮助下打开/关闭它。

现在的问题是，如果我正在设置它，那时它会从当前日期通知我前一个。它只出现在一次，然后所有报警通知都能正常工作。

假如我已将警报设置为12,14,16，那么我在设备中将日期设置为15，然后在切换按钮上，然后它会在此时通知我14。然后一切都很顺利。

它在逻辑上是否正确或我的代码中是否有任何问题？

是否应该发生？

请参阅我为警报通知设置的以下代码：

public void startTwoMonthAlarmNotification() {

        // ===================== GST ALARM FOR THE TWO MONTHS ==========================
        // for the GST 20 June 2011
        AM_2M_GST_1 = (AlarmManager) getApplicationContext().getSystemService(Context.ALARM_SERVICE);

        in1.putExtra("MyMessage","Your 2 Monthly GST return is DUE on 20th June 2011.");
        PI_2M_GST_1 = PendingIntent.getBroadcast(this, 0, in1, PendingIntent.FLAG_UPDATE_CURRENT);
        Calendar calendar_GST_18_June_2011 = Calendar.getInstance();
        calendar_GST_18_June_2011.setTimeInMillis(System.currentTimeMillis());
        calendar_GST_18_June_2011.set(2011, 5, 18, mHour, mMinute, 0);

        }

以下代码用于取消关闭toogleButton上的所有通知警报：

        AM_2M_GST_1.cancel(PI_2M_GST_1);
    AM_2M_GST_2.cancel(PI_2M_GST_2);
    AM_2M_GST_3.cancel(PI_2M_GST_3);
    AM_2M_GST_4.cancel(PI_2M_GST_4);
    AM_2M_GST_5.cancel(PI_2M_GST_5);
    AM_2M_GST_6.cancel(PI_2M_GST_6);
    AM_2M_PROVISIONAL_1.cancel(PI_2M_PROVISIONAL_1);
    AM_2M_PROVISIONAL_2.cancel(PI_2M_PROVISIONAL_2);
    AM_2M_PROVISIONAL_3.cancel(PI_2M_PROVISIONAL_3);
    AM_2M_TERMINAL_1.cancel(PI_2M_TERMINAL_1);

Answer 1

首先，你必须取消旧的AlarmManager和Pending Intent。在这里你没有取消你的待定意图。只需取消使用代码 -

alaramManagerObj.cancel(pendingIntent);
pendingIntent.cancel();

这将清除您的不受欢迎的通知，仅适用于提供的警报。如果要检查警报，请确定该日期的指定日期。请检查一下 -

Calendar c = Calendar.getInstance(); 
c.set(2011, 1, 20); 
long mills = c.getTimeInMillis(); 
long currentTime = System.currentTimeMillis(); 
int x = (mills<=currentTime)?0:1;

如果日期未通过，整数x将返回0，否则返回1.使用此代码满足您的需求。

希望这可以帮到你。
