Android: ListView adding Items on scroll

Question

I am getting data from server in a listview using a custom adapter . The data coming from server is a large amount having images with text. Now I need to load the data each time only 10 items and when I scroll down it should load more 10 items and so on. Her is how I am setting adapter code. I don't understand now how to handle this situation inside the onscroll method. I am loading all items from server at once and assigning to an arraylist. So inside onscroll method what should I do, please help me with some code.

list = (ArrayList<ListItems>) control.Table.GetData();

        final ListView listview = (ListView)findViewById(R.id.user_data);

        adapter = new customAdapter(this, list);
        adapter.setLayout(this, layout);
        listview.setAdapter(adapter);


        listview.setOnScrollListener(new OnScrollListener() {
            @Override
            public void onScrollStateChanged(AbsListView view, int scrollState) {
            }

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

               final int lastItem = firstVisibleItem + visibleItemCount;
               if(lastItem == totalItemCount) {
                   //Here I have to add next 10 items from arraylist

               }
            }
        });

I think large amount of text and images in a listview will be handle by android, I remember in a video Google I/O that even a million rows in a listview, android can handle hit. just implement the best practice on how to manage views/rows in a listview just to avoid recreating the rows everytime it will be viewed.
