Question

Hi am working on an android application. And am using a listview in some of my activities.

The problem is all of my listviews displayed are much longer so that the user needs to scroll the whole list to go for the last item.

Am trying to implement a pagination for this, like at first say only 20 items need to displayed on the listview. And at the end of my listview i need a titlebar which have next & previous buttons and on clicking on next button the listview will load the next records from 21st to 40 and so on.

Am using java rest webservice to load the listview.

Can anyone give me a good suggestion for solving my problem.?

Answer 1

I suggest than you load list data in a custom Adapter class that extends BaseAdapter class. Like @oriolpons suggested, you should add a footer view, and when you click on button next call some method that is fetching next for example 20 rows, and then add them in your adapter object and call notifyDataSetChanged().

For example

private OnClickListener mListener = new OnClickListener() {

    public void onClick(View v) {
        ArrayList<YourObject> al = getSomeData(int startRow, int endRow);
                    MyCustomAdapter adapter = new MyCustomAdapter();
                    for(YourObject a : al)
                       adapter.add(a);
                       getListView.setAdapter(adapter);
                       notifyDataSetChanged();
    }
};

Hope this helps.
