解决方案
它，是因为有一个事实，即<一href="http://developer.android.com/reference/android/app/AlarmManager.html#setRepeating%28int,%20long,%20long,%20android.app.PendingIntent%29"相对=nofollow> setRepeating（）将立即触发报警，如果它是在过去。您将需要计算的时间差，然后shedule报警。添加到日历似乎是一个简单的方法来做到这一点。
例如，如果你使用日历和当前的一天是星期一：
台历挂历= Calendar.getInstance（）;
calendar.set（Calendar.HOUR_OF_DAY，12）;
calendar.set（Calendar.MINUTE，00）;
calendar.set（Calendar.SECOND，00）;
calendar.add（Calendar.DATE，6）; //增加6天。
I have an alarm manager that triggers a notification every Sunday. It works fine but whenever I open the application, the notification is displayed even if it is not Sunday. Is the onReceive method triggered when the application opens? How could I change it so the notification does not display when the app is opened?

}
}
解决方案
It has to do with the fact that setRepeating() will trigger the alarm immediately if it is in the past. You will need to compute the time difference then shedule the alarm. Adding to the calendar seems like an easy way to do it.
Eg, if you were using Calendar and the current day is Monday:
Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.HOUR_OF_DAY, 12);
calendar.set(Calendar.MINUTE, 00);
calendar.set(Calendar.SECOND, 00);
calendar.add (Calendar.DATE, 6); //add 6 days.
