使用AlarmManager编辑警报

Question

我试图制作一个简单的作业提醒应用程序我使用此功能设置闹钟：

void setAlarm(int year, int month, int day, int hour, int minute, int second, String lesson, String description, int id)
{
    Intent intent1 = new Intent(this, MyReceiver.class);
    Calendar calendar = Calendar.getInstance();
    calendar.set(Calendar.YEAR, year);
    calendar.set(Calendar.MONTH, month);
    calendar.set(Calendar.DAY_OF_MONTH, day);
    calendar.set(Calendar.HOUR_OF_DAY, hour);
    calendar.set(Calendar.MINUTE, minute);
    calendar.set(Calendar.SECOND, second);
    intent1.putExtra("LESSON", lesson);
    intent1.putExtra("DESC", description);
    intent1.putExtra("ID", id);
    PendingIntent pendingIntent = PendingIntent.getBroadcast(this, id, intent1, PendingIntent.FLAG_UPDATE_CURRENT);
    AlarmManager am = (AlarmManager) this.getSystemService(ALARM_SERVICE);
    am.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), pendingIntent);
}

人们说如果你想编辑你需要有完全相同的pendingIntent所以我做了但它似乎没有工作

当我设置闹钟并对其进行编辑而不关闭时，第一个闹钟似乎自动取消

我不知道我做错了什么

感谢您的帮助
