在我的应用程序已经设置了许多报警通知。都是在不同的日期，但具有相同的时间。而我与切换按钮的帮助下将它设置开/关。
现在的问题是，如果我把它放在那么在那个时候它给我的previous一个通知，从当前日期。它只出现一次，然后所有的报警通知工作正常。
假设，如果我已经设置了闹钟，以在12,14,16日期，然后我设定的日期为15我的设备和切换按钮，然后它给了我14通知在那个时候。然后，一切都很好。
因此，它是逻辑上是正确还是有我的code什么问题？
如果它可以发生或不？
请看到我已经设置了报警通知下面code：

首先，您必须取消旧AlarmManager和待定的意图。在这里，你没有取消挂起的意图。只是取消使用THIC code -
alaramManagerObj.cancel（的PendingIntent）;pendingIntent.cancel（）; 这将是清楚您不需要的通知，只为提供报警工程。如果你想与指定的日期检查您的报警，该日期即通过与否。就在这个检查 -
日历C = Calendar.getInstance（）;c.set（2011，1，20）;长钢厂= c.getTimeInMillis（）;长currentTime的= System.currentTimeMillis的（）;INT X =（钢厂＆LT; = currentTime的）0：1; 在整数 X 将返回0，如果日期不通过，否则返回1。使用此code您的需求。
但愿这可以帮助你。
In My application i have set the many Alarm Notification. All are at different date but with the same time. And i am setting it on/off with the help of the toggle Button.
Now the Problem is, If i am setting it on then at that time it gives me notification of the previous one from current date. it only appear at once and then all alarm notification works fine.
Suppose if i have set the alarm at 12,14,16 date then i set the date as 15 in my device and on the toggle button then it gives me notification of 14 at that time. And then all goes fine.
So is it logically correct or is there any problem in my code ?
Should it be happened or not ?
Please see the Below code that i have set for the alarm notification:
public void startTwoMonthAlarmNotification() {

Below code is for the Canceling all the notification alarm on the toogleButton off:
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);
解决方案
First you must cancel the old AlarmManager and Pending Intent. Here you didn't cancel your Pending Intent. Just cancel that use thic code -
alaramManagerObj.cancel(pendingIntent);
pendingIntent.cancel();
This will be clear your unWanted Notification and works only for provided Alarm. If you want to Check your alarm with Specified date for that date is passed or not. Just check with this -
Calendar c = Calendar.getInstance();
c.set(2011, 1, 20);
long mills = c.getTimeInMillis();
long currentTime = System.currentTimeMillis();
int x = (mills<=currentTime)?0:1;
In the integer x will return 0 if the date is not passed, else returns 1. Use this code to your needs.
Hope this may helps you.
