前提是引用Volley的异步机制，引入它的jar包
public void getJSONByVolley() { //mContext为上下文， RequestQueue requestQueue = Volley.newRequestQueue(mContext); String JSONDataUrl = "http://sjshop.easyder.com/app/order_index/getCart?buyer_id=511"; final ProgressDialog progressDialog = ProgressDialog.show(mContext, "正在下载", "Loading......"); progressDialog.setCancelable(true);//progressDialog可以取消 JsonObjectRequest jsonObjectRequest = new JsonObjectRequest( Request.Method.GET, JSONDataUrl, null, new Response.Listener<JSONObject>() { @Override public void onResponse(JSONObject response) { try { getcartJson(response); } catch (Exception e) { e.getMessage(); } if (progressDialog.isShowing() && progressDialog != null) { progressDialog.dismiss(); } } }, new Response.ErrorListener() { @Override public void onErrorResponse(VolleyError arg0) { System.out.println("sorry,Error"); } }); requestQueue.add(jsonObjectRequest); Log.i(TAG, "shopBeanList ---->解析完Json "); } //getcart的网络解析，参数-->JSONObject public void getcartJson(JSONObject jsonObject) { // 创建商店列表 List<ShopBean> shopBeanList= new ArrayList<ShopBean>(); JSONObject objectInfo = null; try { objectInfo = jsonObject.getJSONObject("info"); JSONArray arraygroup = objectInfo.getJSONArray("group"); for (int i = 0; i <arraygroup.length() ; i++) { JSONObject item = arraygroup.getJSONObject(i); ShopBean shopBean = new ShopBean(item); shopBeanList.add(shopBean); Log.d(TAG, "shopBeanList-----> "+ item); } } catch (JSONException e) { e.printStackTrace(); } if(mCallback!=null){ mCallback.getDat(shopBeanList); } }
实体类中添加了一个JsonObject的构造函数
ShopBean实体类：
/** * Created by Administrator on 2015/7/19 0019. */ public class ShopBean { private int seller_uid;//店铺ID private String seller_name;//店铺名称 public List<GoodsBean> goodsList;//商品信息列表 public String getSeller_name() { return seller_name; } public void setSeller_name(String seller_name) { this.seller_name = seller_name; } public int getSeller_uid() { return seller_uid; } public List<GoodsBean> getGoodsList() { return goodsList; } public void setGoodsList(List<GoodsBean> goodsList) { this.goodsList = goodsList; } public void setSeller_uid(int seller_uid) { this.seller_uid = seller_uid; } public ShopBean() { } //构造函数，参数为JSONObject型 public ShopBean(JSONObject jsonObject) { this.seller_uid = jsonObject.optInt("seller_uid"); this.seller_name = jsonObject.optString("seller_name"); GoodsBean goodsBean; JSONArray jsonArray = jsonObject.optJSONArray("goods"); if (jsonArray != null && jsonArray.length() > 0) { try { goodsList = new ArrayList<>(); for (int j = 0; j < jsonArray.length(); j++) { goodsBean = new GoodsBean(jsonArray.getJSONObject(j)); goodsList.add(goodsBean); } } catch (JSONException e) { e.printStackTrace(); } } } }
GoodsBean实体类：
/** * Created by Administrator on 2015/7/24. */ public class GoodsBean { private int stock_id;//商品ID private String goods_name;//商品名称 private int qty;//商品的星级 private boolean is_choose;//是否选中 private double price;//单价 private String goods_img;//图片链接 private String extend;//图片拓展 private int stock_num;//商品数量 private double goodsTotalPrice;//商品总价 private double rate;//商品税率 public String getGoods_name() { return goods_name; } public void setGoods_name(String goods_name) { this.goods_name = goods_name; } public int getQty() { return qty; } public void setQty(int qty) { this.qty = qty; } public boolean is_choose() { return is_choose; } public void setIs_choose(boolean is_choose) { this.is_choose = is_choose; } public double getPrice() { return price; } public void setPrice(double price) { this.price = price; } public String getGoods_img() { return goods_img; } public void setGoods_img(String goods_img) { this.goods_img = goods_img; } public String getExtend() { return extend; } public void setExtend(String extend) { this.extend = extend; } public int getStock_num() { return stock_num; } public void setStock_num(int stock_num) { this.stock_num = stock_num; } public double getGoodsTotalPrice() { return goodsTotalPrice; } public void setGoodsTotalPrice(double goodsTotalPrice) { this.goodsTotalPrice = goodsTotalPrice; } public double getRate() { return rate; } public void setRate(double rate) { this.rate = rate; } public int getStock_id() { return stock_id; } public void setStock_id(int stock_id) { this.stock_id = stock_id; } public GoodsBean(JSONObject jsonObject){ this.stock_id = jsonObject.optInt("stock_id"); this.goods_name = jsonObject.optString("goods_name"); this.qty = jsonObject.optInt("qty"); this.is_choose = jsonObject.optBoolean("is_choose"); this.price = jsonObject.optDouble("price"); this.goods_img = jsonObject.optString("goods_img"); this.extend = jsonObject.optString("extend"); this.stock_num = jsonObject.optInt("stock_num"); this.goodsTotalPrice = jsonObject.optDouble("goodsTotalPrice"); this.rate = jsonObject.optDouble("rate"); } public GoodsBean(){ } @Override public String toString() { return "等级:" + qty + " " + "税率:" + rate ; } }
