scrollable activity in as3 is not working perfect for android air

Question

i want to make a scrollable index of particular math book for android version where i will be able to scroll a movie clip consists of 56 child movieclips(there are chapter 1 to chapter 56 child clips has made "buttons_all" parentclip) and when i will choose a child movie clip it will go to selected label or chapter(suppose if i click chapter 1 movie clip it will gotoAndPlay("chapter 1")).i had made the parent movieclip scrollable and added eventlistener to each child movie clip..but when i want to scroll it is doing two things,first it scrolls then go to that "chapter" that i clicked to start scrolling whether i want to go this chapter or not.to solve that i added a timer event to create an interval to stop selecting chapter immediately before i want to select a specific chapter..but it is working partially.i want to add this interval to every button.because i dont have a scrollbar here for up and down..please help me to solve this..here is my part of code

 var pat1:MovieClip = scrolling_manu.buttons_all.part1;

    var listTimer:Timer; // timer for all events

     var tapDelayTime:Number = 0;
     var maxTapDelayTime:Number = 20; // change this to increase or descrease tap sensitivity

     var tapEnabled:Boolean = false;

 init();
 function init()
    {
        //removeEventListener(Event.ADDED_TO_STAGE, init);

        pat1.addEventListener(TouchEvent.TOUCH_BEGIN, onmouseDown );
        //trace("hit");

         pat1.addEventListener(TouchEvent.TOUCH_END, onmouseUp );
        listTimer = new Timer( 33 );
        listTimer.addEventListener( TimerEvent.TIMER, onListTimer);
        listTimer.start();

    }
    function onmouseDown( e:TouchEvent ):void 
    {

         handleItemPress()
    }
    function onmouseUp( e:TouchEvent ):void 
    {

        onTapDisabled();
        //listTimer.stop();
    }

 function onListTimer(e:Event):void
    {
        // test for touch or tap event
        if(tapEnabled)
            onTapDelay();


    }


    function onTapDisabled():void
    {

            tapEnabled = false;
            tapDelayTime = 0;

    }       
function onTapDelay():void

    {
        tapDelayTime++;

        if(tapDelayTime > maxTapDelayTime ) 
        {
            //tapItem.selectItem();
            tapDelayTime = 0;
            tapEnabled = false;
            trace("hit");
            pat1.gotoAndPlay("over1");
            pat1.addEventListener(TouchEvent.TOUCH_END, onmouseUp );
        }

    }

    function handleItemPress()
    {
            tapDelayTime = 0;
            tapEnabled = true;
            trace("hit");

    }

Firstly, I recommend you to convert all vector images to raster. It's very hard for processor to animate vector images.

Delete all code after drop_me function.

Write this:

scrolling_manu.buttons_all.addEventListener(TouchEvent.TOUCH_BEGIN, onTouchBegin);
scrolling_manu.buttons_all.addEventListener(TouchEvent.TOUCH_END, onTouchEnd);

var touchedPart:MovieClip;
var posY:int;

function onTouchBegin(event:TouchEvent):void
{
    touchedPart = event.target as MovieClip;
    posY = scrolling_manu.buttons_all.y;
}

function onTouchEnd(event:TouchEvent):void
{
    // if list was been moved, that isn't a tap.
    if (posY == scrolling_manu.buttons_all.y)
    {
        trace("part tapped", touchedPart.name);
        touchedPart.gotoAndPlay("over1");
    }
}
