Android Listview slow down scroll speed

When a user swipes on a ListView its' scrolling speed can get pretty high. I'd like to limit the speed - is it possible ?

the thing is - u can swipe it really fast and it needs to be limited — user1462299, Jul 12 '12 at 08:15
I mean the scrolling speed gets high if u swipe it abruptly. I want to limit the scrolling speed — user1462299, Jul 12 '12 at 08:26
Try this:android:fastScrollEnabled="false" in xml under listview — AkashG, Jul 12 '12 at 08:28
AkashG, it shows me additional drag thing - it doesn't seem to lessen the speed. — user1462299, Jul 12 '12 at 08:46
Because it is by default functionality which cannot be controlled.it depends on the Motion of touch user applies on it. — AkashG, Jul 12 '12 at 08:48
Think im with AkashG on this, if you have to do it, you have to extend listview, override the onTouchEvent with a gesturelistener, and in that do it. But thats a huuuge amount of work to get it to work propperly i think. — Anders Metnik, Jul 12 '12 at 08:51

Check this out -:

private class SpeedMeterOnScrollListener implements OnScrollListener {

        private long timeStamp;
        private int lastFirstVisibleItem;

        public SpeedMeterOnScrollListener() {
            timeStamp = System.currentTimeMillis();
            lastFirstVisibleItem = 0;
        }

        @Override
        public void onScroll(AbsListView view, int firstVisibleItem, int visibleItemCount, int totalItemCount) {
            long lastTime = System.currentTimeMillis();
            //calculate speed by firstVisibleItem, lastFirstVisibleItem, timeStamp and lastTime
            timeStamp = lastTime;
            lastFirstVisibleItem = firstVisibleItem;
        }

        @Override
        public void onScrollStateChanged(AbsListView view, int scrollState) {
        }
    }
