这是我未决的意图

alarmMgr= (AlarmManager)getSystemService(Context.ALARM_SERVICE);
                Intent intent = new Intent(this,BroadcastReceiver_Class.class);
                /*intent.putExtra("alarm_time_minutes",minutes);*/
                pendingIntent = PendingIntent.getBroadcast(this,requestCode,intent,requestCode);
                alarmMgr.set(AlarmManager.RTC_WAKEUP,cal.getTimeInMillis(),pendingIntent);

提前致谢..
