如上图所示

右边也是一个数据列表，但它里面包含图片、文本框等等，并且每列都会有与之对应的餐类。

Android 部分

获取右侧商品listview的控件

private ListView rightListView = (ListView) view.findViewById(R.id.menu_lvmenu);

通过Http请求服务器，设置方法名参数到后台查询成功后返回json字符串，JSONObject获取json对象data，再通过gson1.fromJson获取数据到mGoodsList集合中，再执行initData（）方法，初始化数据。initData方法中配置了ListView的适配器，主要是显示列表数据。

String urlgoodsAll=ServiceUrls.getMenuItemsMethodUrl("selectGoodsAll")+ "?catalog_food_id=" + 0;OkHttpTool.httpPost(urlgoodsAll, null, new OkHttpTool.ResponseCallback() {    @Override    public void onResponse(boolean isSuccess, int responseCode, String response, Exception exception) {        mActivityContext.runOnUiThread(new Runnable() {            @Override            public void run() {                String strText = "网络环境不佳，请稍后再试";                if (isSuccess && responseCode == 200 && Tools.isNotNull(response)) {                    try {                        JSONObject jsonObject = new JSONObject(response);                        String strData =  jsonObject.getString("data");                        JSONArray jsonArray=new JSONArray(strData);                        Gson gson1=new Gson();                        mGoodsList= gson1.fromJson(strData, new TypeToken>() {}.getType());                        initData();                    } catch (JSONException e) {                        e.printStackTrace();                    }                }            }        });    }});private void initData() {    rightAdapter = new RightAdapter(mActivityContext,mGoodsList);    //setAdapter 适配器就是用来显示列表项    rightListView.setAdapter(rightAdapter); }

RightAdapter适配器实现SectionIndexer接口， getCount获取list集合中的条目个数，getItem根据索引获取对应的内容，getItemId获取索引，getView获取当前条目需要展示的布局效果，viewProductHolder通过容器来存储，优化找控件的内存，判断如果没有可复用那就获取控件绑定到view上，最后对控件的数据进行设置，再通过发送请求到后端查询每一列的图片。

class RightAdapter extends BaseAdapter implements SectionIndexer {     private List list = null;     private Context mContext;     public RightAdapter(Context mContext, List mGoodsList) {         this.mContext = mContext;         this.list = mGoodsList;     }    @Override     public int getCount() {          return this.list.size();     }     @Override     public Object getItem(int position) {          return list.get(position);     }     @Override     public long getItemId(int position) {          return position;     }     @Override     public View getView(int position, View convertView, ViewGroup parent) {          final ViewProductHolder viewProductHolder;         final GoodsBean mGoods = list.get(position);         if (convertView == null) {             convertView = LayoutInflater.from(mContext).inflate(R.layout.product_item, null);             TextView tvTag = (TextView) convertView.findViewById(R.id.cate_name);             TextView tvTitle = (TextView) convertView.findViewById(R.id.product_name_view);             ImageView productImage = (ImageView) convertView.findViewById(R.id.product_imageView);             TextView countView = (TextView) convertView.findViewById(R.id.add_count_view);             TextView tvPrice = (TextView) convertView.findViewById(R.id.product_price_view);             ImageView removeProductImage = (ImageView) convertView.findViewById(R.id.delete_product_view);             ImageView addProductImage = (ImageView) convertView.findViewById(R.id.add_product_view);             viewProductHolder = new ViewProductHolder(tvTag,tvTitle,productImage, countView,tvPrice, removeProductImage, addProductImage);             convertView.setTag(viewProductHolder);         } else {             viewProductHolder = (ViewProductHolder) convertView.getTag();         }         //如果有该类型，则隐藏         int section = getSectionForPosition(position);         if (position == getPositionForSection(section)) {             viewProductHolder.tvTag.setVisibility(View.VISIBLE);             viewProductHolder.tvTag.setText(mGoods.getCatalogFoodname());         } else {             viewProductHolder.tvTag.setVisibility(View.GONE);         }         viewProductHolder.tvTitle.setText(mGoods.getGoodsName());         viewProductHolder.tvPrice.setText("￥" + mGoods.getGoodsPrice());         int salecount = UIHelper.saleCount(getActivity(), mGoods.getGoodsId(),businessId);         if (salecount > 0) {             viewProductHolder.countView.setText(salecount + "");             viewProductHolder.countView.setVisibility(View.VISIBLE);             viewProductHolder.removeProductImage.setVisibility(View.VISIBLE);         } else {             viewProductHolder.countView.setText(0 + "");             viewProductHolder.countView.setVisibility(View.GONE);             viewProductHolder.removeProductImage.setVisibility(View.GONE);         }         /**          * 查询获取商品的图片          * 请求          */         List photo= Collections.singletonList(mGoods.getGoodsPicture());         for (int i=0;i
