Expandable Listview Child count Dynamically

Issue

I am making an web service based Android application. My problem is child count with expandableListView. I must use 2 different web services. Namely, 1st web service is getting parent informations. I want this, when i clicked parent 2nd web service must start and get child informations. My child counts are flexible. 1st parent have 2 childs, 2nd parent have 5 childs. How can i manage them.

I am using expandablelistviewadapter. This adapter want child counts before using this code "listview.setadapter(adapter)"

So I want to use dynamic child counts. When I clicked parent dialog will show and childs getting from server.

Solution

I don't get your questin. Writing a custom adapter is the way to go in most cases. So you are on the right way. This adapter should use a datastructure what does what you want.

edit:
this should work right? (Item is my baseclass for dynamic data)

public class MyBaseListAdapter implements ListAdapter {
    List<? extends Item> items;
    @Override
    public int getCount() {
        return items.size();
    }

edit II:
this line may also be improtant for you:

adapter.notifyDataSetChanged();

and you should try to sync or block access while you change the data
