在Grid-view中动态添加多个按钮

Question

任何人都可以告诉我在Grid-View项目中动态设置按钮数量的方法。我的意思是，假设我有3X3的grid-view（由不同产品的类别组成），当我点击它的第一项时，我得到按钮列表其子产品在网格视图中的第一次和数量根据子产品的可用性而不同。

网格视图项目内显示的按钮列表可能因每个项目点击而有所不同。我是android新手，所以任何帮助将不胜感激

这是我的xml适配器： -

这是我的适配器类： -

public class ProductSelectorAdapter extends BaseAdapter {

	Activity activity;
	List<SelectorTest> listSelector;
	private Button btn;
	List<catagoriesListModal> _categories;

	public ProductSelectorAdapter(Activity activity,
			List<SelectorTest> 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);

					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;
	}

这是我的SelectorTest模型类： -

import java.util.List;



public class SelectorTest {
	int id;
	String name;
	int image;
	List<catagoriesListModal> 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<catagoriesListModal> getCategories() {
		return categories;
	}

	public void setCategories(List<catagoriesListModal> categories) {
		this.categories = categories;
	}

}

这是我的catagoriesListModal类： -

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;
	}

}

谢谢
