simply create your views in xml, then onclick button setvisibility or gone — Engr Waseem Arain, May 21 '14 at 11:33
Your question is so vague that we can assume it is a duplicate. If it is not : provide more details on what/why it is different and the duplicate will be removed. — ben75, May 21 '14 at 11:34
engar Waseem Arain, the child view may be 10 or 1000 based on user. so it is not possible in xml layout — user1517638, May 21 '14 at 11:40

i found the answer for my question. for every button click just inflate the xml desiged layout. so the layout can be added one by one. the codes are here

LayoutInflater IInflater = (LayoutInflater) context
            .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    String[] names = { "Joe", "Jane", "Herkimer" };
    while (run >= 1) {

        View storeitems = IInflater.inflate(R.layout.product_child_item,
                null);
        productCode = (TextView) storeitems.findViewById(R.id.productCode);
        productName = (TextView) storeitems.findViewById(R.id.productName);
        noOfQuantity = (TextView) storeitems
                .findViewById(R.id.noOfQuantity);
        int i = run - 1;
        productCode.setText(names[i]);
        linearLayout.addView(storeitems, 0);
        run--;
    }

Implement OnChildClickListener in your Activity and implemet this method..

@Override
public boolean onChildClick(ExpandableListView parent, View v,
        int groupPosition, int childPosition, long id) {

           //Add new chid data in your list (ex ArrayLis or Array whatever you use)
          adapter.notifyDataSetChanged() // BaseExpandableListAdapter's adapter...


    return true;
}

Is it work work for you?
