If you want the click handler specifically on the button inside the listview you need something like this:

public class CustomListAdapter: BaseAdapter {
    public CustomListAdapter(Context context, EventHandler buttonClickHandler) {
        _context = context;
        _buttonClickHandler = buttonClickHandler;
    }

    public View GetView(int position, View convertView, View parent) {
        var itemView = convertView;

        if(itemView == null) {
            var layoutInflater = (LayoutInflater)_context.GetSystemService(Context.LayoutInflaterService);
            itemView = layoutInflater(Resource.Layout.ItemView);
        }

        var button = itemView.FindViewById<Button>(Resource.Id.MyButton);
        button.Click += _buttonClickHandler;
    }

    // ... Rest of the code omitted for simplicity.
}

This code does not take into account the fact that there could be another handler attached to the button. Make sure that you decouple the old one, before coupling a new one. Or add some sort of detection that you've added the click handler before and don't add another one.
