add multiple buttons dynamically inside Grid-view

Question

Can any one tell me the approach to set number of buttons dynamically in Grid-View items.I mean,Suppose i am having the grid-view(consist of categories of different products) of 3X3 and when i click on its first item i get the list of buttons of its sub-product inside grid-view first time and number differs for every item based on the availability of sub-products.

The list of buttons shown inside grid-view item may differ for every item click.I am new to android so any help will be appreciated

Here is my xml of adapter :-

Here is my adapter class :-

public class ProductSelectorAdapter extends BaseAdapter {

    Activity activity;
    List listSelector;
    private Button btn;
    List _categories;

    public ProductSelectorAdapter(Activity activity,
            List listSelector) {
        this.activity = activity;
        this.listSelector = listSelector;
    }

    @Override
    public int getCount() {
        return listSelector.size();
    }

    @Override
    public SelectorTest getItem(int position) {
        return listSelector.get(position);
    }

    @Override
    public long getItemId(int position) {
        return position;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        final ViewHolder viewHolder;
        _categories = listSelector.get(position).getCategories();
        if (convertView == null) {
            LayoutInflater inflater = (LayoutInflater) activity
                    .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            convertView = inflater.inflate(R.layout.selector_items, parent,
                    false);
            viewHolder = new ViewHolder();
            viewHolder.tvProductName = (TextView) convertView
                    .findViewById(R.id.tv_product);
            viewHolder.imgView = (ImageView) convertView
                    .findViewById(R.id.img_product);
            viewHolder.viewRightLine = (View) convertView
                    .findViewById(R.id.view_right_line);
            viewHolder.lnrLayout = (LinearLayout) convertView
                    .findViewById(R.id.lnr_test);

            convertView.setTag(viewHolder);

        } else {
            viewHolder = (ViewHolder) convertView.getTag();
        }
        if (!activity.getResources().getBoolean(R.bool.landscape_only)) {
            if (position % 2 != 0) {
                viewHolder.viewRightLine.setVisibility(View.GONE);
            } else {
                viewHolder.viewRightLine.setVisibility(View.VISIBLE);
            }
        } else {
            if (position % 3 != 0 & position % 3 != 1) {
                viewHolder.viewRightLine.setVisibility(View.GONE);
            } else {
                viewHolder.viewRightLine.setVisibility(View.VISIBLE);
            }
        }

        SelectorTest selectorTest = listSelector.get(position);
        viewHolder.tvProductName.setText(selectorTest.getName());
        viewHolder.imgView.setImageResource(selectorTest.getImage());
        viewHolder.imgView.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                if (activity.getResources().getBoolean(R.bool.landscape_only)) {
                    viewHolder.lnrLayout.setVisibility(View.VISIBLE);
                    viewHolder.imgView.setVisibility(View.GONE);

                    for (int i = 0; i < _categories.size(); i++) {

                        btn = new Button(activity);
                        btn.setText(_categories.get(i).getName());

                        viewHolder.lnrLayout.addView(btn);
                        int idx = viewHolder.lnrLayout.indexOfChild(btn);
                        btn.setTag(Integer.toString(idx));

                        btn.setOnClickListener(new OnClickListener() {

                            @Override
                            public void onClick(View v) {
                                String idxStr = (String) v.getTag();
                                Toast.makeText(activity, idxStr,
                                        Toast.LENGTH_SHORT).show();

                            }
                        });
                    }
                } else {
                    Session.ChangeFragmentWithBack(new ProductDetailFragment(),
                            "ProductDetailFragment", "ProductDetailFragment", 0);
                }

            }
        });

        return convertView;
    }

    static class ViewHolder {
        TextView tvProductName, tvTest;
        ImageView imgView;
        View viewRightLine;
        ListView lstroduct;
        ScrollView scrlLstItems;
        LinearLayout lnrLayout;
        Button btn1, btn2, btn3;
    }

Here is my SelectorTest model class :-

import java.util.List;

public class SelectorTest {
    int id;
    String name;
    int image;
    List categories;

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getImage() {
        return image;
    }

    public void setImage(int image) {
        this.image = image;
    }

    public List getCategories() {
        return categories;
    }

    public void setCategories(List categories) {
        this.categories = categories;
    }

}

Here is my catagoriesListModal class :-

public class catagoriesListModal {
    String name;
    int id;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

}
