You can refer to blog - Create list view with custom list view adapter.

Now we will implement pagination in this list view.

• We will add 20 items each time to the list view.
• After 18th element is displayed on the screen we will call a method to load new items to the list view, so that user does not wait for new items to be loaded.(In real cases you might be loading from a server and this might take much time).
• We will restrict our pagination after 400 elements have been displayed.( It is a replication of the scenario when the server has no more items to be displayed).

We will be setting a onScrollListener() on the listView to check when to load new items and add them to the list.

listView.setOnScrollListener(new AbsListView.OnScrollListener() {
            @Override
            public void onScrollStateChanged(AbsListView absListView, int i) {

            }

            @Override
            public void onScroll(AbsListView absListView, int firstVisibleItem, int visibleItemCount, int totalItemCount) {
                if(firstVisibleItem+visibleItemCount > totalItemCount-2 && totalItemCount < maxRecords){
                    personAdapter.add(bootData());
                    personAdapter.notifyDataSetChanged();
                }
            }
        });
