如何在android中为可扩展listview中的子级设置限制

我正在创建一个包含listview的android应用程序
在listview中，我有一个可扩展的高度listview。对于父listview，我将限制设置为仅显示两个列表项。但是在可扩展列表视图中，我没有设置任何限制。
我想知道如何为listview中的子视图（即可扩展listview）设置限制。下面是我的listview one适配器代码：

  public class Daybook_adapter extends BaseAdapter {
    Context context;
    Activity activity;


    //DaybookSwipeMenuListView daybookdetailviewlist;
    public Daybook_adapter(Activity activity, ArrayList<Daybook> list) {

        //this.context = context;
        this.activity = activity;
        entriesdaybook = list;

    }


    @Override
    public int getCount() {

        return entriesdaybook.size();
    }

    @Override
    public Object getItem(int position) {

        return entriesdaybook.get(position);
    }

    @Override
    public long getItemId(int position) {

        return position;
    }


    @Override
    public View getView(int position, View convertView, ViewGroup arg2) {

                    .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
