我想在特定日期和时间（25/12/2012 12:00）显示一个对话框，我正在使用此代码。我设置为 11 个月（因为 0 是 gen），但警报没有启动。我的错误是什么？

Calendar cal=Calendar.getInstance();
    cal.set(Calendar.MONTH,11);
    cal.set(Calendar.YEAR,2012);
    cal.set(Calendar.DAY_OF_MONTH,25);
    cal.set(Calendar.HOUR_OF_DAY,12);
    cal.set(Calendar.MINUTE,00);
    cal.set(Calendar.SECOND,0);

Intent _myIntent = new Intent(context, Notify.class);
    PendingIntent _myPendingIntent = PendingIntent.getBroadcast(context, 123, _myIntent, PendingIntent.FLAG_UPDATE_CURRENT|  Intent.FILL_IN_DATA);

AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
alarmManager.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), _myPendingIntent);

Look at below code about how i am going to set the alarm for the December month:

// for Alarm 25/12/2012 at 12.00   
Calendar myAlarmDate = Calendar.getInstance();
myAlarmDate.setTimeInMillis(System.currentTimeMillis());
myAlarmDate.set(2012, 11, 25, 12, 00, 0);
AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);

Intent _myIntent = new Intent(context, AlarmReceiverNotificationForEveryMonth.class);
_myIntent.putExtra("MyMessage","HERE I AM PASSING THEPERTICULAR MESSAGE WHICH SHOULD BE SHOW ON RECEIVER OF ALARM");
PendingIntent _myPendingIntent = PendingIntent.getBroadcast(context, 123, _myIntent, PendingIntent.FLAG_UPDATE_CURRENT);
alarmManager.set(AlarmManager.RTC_WAKEUP, myAlarmDate.getTimeInMillis(),_myPendingIntent);

You can update the above code with your intent and class and you will get your desire output.

Hope this help you.
