Use the following method and enjoy!

    private void setListViewScrollable(final ListView list) {
    list.setOnTouchListener(new OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            listViewTouchAction = event.getAction();
            if (listViewTouchAction == MotionEvent.ACTION_MOVE)
            {
                list.scrollBy(0, 1);
            }
            return false;
        }
    });
    list.setOnScrollListener(new OnScrollListener() {
        @Override
        public void onScrollStateChanged(AbsListView view,
                int scrollState) {
        }

        @Override
        public void onScroll(AbsListView view, int firstVisibleItem,
                int visibleItemCount, int totalItemCount) {
            if (listViewTouchAction == MotionEvent.ACTION_MOVE)
            {
                list.scrollBy(0, -1);
            }
        }
    });
}

listViewTouchAction is a global integer value. If you can replace the line

list.scrollBy(0, 1);

with something else please share it with us.
