to get the the first item of the listview having a different layout the following code can be used. But the listview don't move when the items in the list are less than the no of visible items.

list.setOnScrollListener(new OnScrollListener() {

        @Override
        public void onScrollStateChanged(AbsListView view, int scrollState) {
            // TODO Auto-generated method stub

        }

        @Override
        public void onScroll(AbsListView view, int firstVisibleItem,
                int visibleItemCount, int totalItemCount) {
            // TODO Auto-generated method stub

            if(firstItem != firstVisibleItem)
            {
                firstItem = firstVisibleItem;
                adapter.notifyDataSetChanged();
            }
        }
    });

and inside the adapter class check if the postion is same as firstItem if its equal then show the detals layout.

Try this

int visibleposition = ListView.getFirstVisiblePosition();

now for this particular position change the background of the list item like this

You can try some method such as

getFirstVisiblePosition

Or this might answer your problem

In getView(), you might inflate a different layout for different position. do something like

 if(position==0){
           inflate(first_layout);
   else{
           inflate(other_layout);
