    lv_best.setOnScrollListener(new OnScrollListener() {
                @Override
                public void onScrollStateChanged(AbsListView view, int scrollState) {
                    switch (scrollState) {
                    case OnScrollListener.SCROLL_STATE_IDLE:
                                         // when list scrolling stops

                                        manipulateWithVisibleViews(view);

                        break;
                    case OnScrollListener.SCROLL_STATE_TOUCH_SCROLL:
                        break;
                    case OnScrollListener.SCROLL_STATE_FLING:
                        break;
                    }
                }

                @Override
                public void onScroll(AbsListView view, int firstVisibleItem,
                        int visibleItemCount, int totalItemCount) { 
                }
            });

private void manipulateWithVisibleViews(AbsListView view){
        int count = view.getChildCount(); // visible views count
        int lastVisibleItemPosition = view.getLastVisiblePosition();

        for (int i = 0; i < count; i++) {
            View convertView = view.getChildAt(i);
            // update views
            }
        }

}
