嵌套JsonArray对已固定的ListView解析

Question

我使用这个library做一个固定的部分列表视图。我的API回应如下。我需要解析嵌套jsonarray但问题是我得到的最后一个对象只针对JSONArray“产品”，使得我得到相同的2列表行项目的第一节头部，而不是2个不同的列表行第二循环中项目。如何解析嵌套的jsonarray并将其添加到模型类？

Answer 1

您可以使用下面

AllCartProduct类

public class AllCartProduct { 

private String sellerId; 
private String sellerName; 
private String email; 
private String sellerImage; 
private List<Product> products = null; 

public String getSellerId() { 
return sellerId; 
} 

public void setSellerId(String sellerId) { 
this.sellerId = sellerId; 
} 

public String getSellerName() { 
return sellerName; 
} 

public void setSellerName(String sellerName) { 
this.sellerName = sellerName; 
} 

public String getEmail() { 
return email; 
} 

public void setEmail(String email) { 
this.email = email; 
} 

public String getSellerImage() { 
return sellerImage; 
} 

public void setSellerImage(String sellerImage) { 
this.sellerImage = sellerImage; 
} 

public List<Product> getProducts() { 
return products; 
} 

public void setProducts(List<Product> products) { 
this.products = products; 
} 

} 

例类

给出。三个模式对象轻松地分析这个JSON

public class Example { 

private List<AllCartProduct> allCartProducts = null; 
private Integer totalQty; 
private Integer ack; 

public List<AllCartProduct> getAllCartProducts() { 
return allCartProducts; 
} 

public void setAllCartProducts(List<AllCartProduct> allCartProducts) { 
this.allCartProducts = allCartProducts; 
} 

public Integer getTotalQty() { 
return totalQty; 
} 

public void setTotalQty(Integer totalQty) { 
this.totalQty = totalQty; 
} 

public Integer getAck() { 
return ack; 
} 

public void setAck(Integer ack) { 
this.ack = ack; 
} 

} 

产品类

public class Product { 

private String id; 
private String productUserId; 
private String name; 
private String desc; 
private String quantity; 
private String unitPrice; 
private Integer totalPrice1; 
private String totalPrice; 
private String itemImage; 
private String totalquantity; 

public String getId() { 
return id; 
} 

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

public String getProductUserId() { 
return productUserId; 
} 

public void setProductUserId(String productUserId) { 
this.productUserId = productUserId; 
} 

public String getName() { 
return name; 
} 

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

public String getDesc() { 
return desc; 
} 

public void setDesc(String desc) { 
this.desc = desc; 
} 

public String getQuantity() { 
return quantity; 
} 

public void setQuantity(String quantity) { 
this.quantity = quantity; 
} 

public String getUnitPrice() { 
return unitPrice; 
} 

public void setUnitPrice(String unitPrice) { 
this.unitPrice = unitPrice; 
} 

public Integer getTotalPrice1() { 
return totalPrice1; 
} 

public void setTotalPrice1(Integer totalPrice1) { 
this.totalPrice1 = totalPrice1; 
} 

public String getTotalPrice() { 
return totalPrice; 
} 

public void setTotalPrice(String totalPrice) { 
this.totalPrice = totalPrice; 
} 

public String getItemImage() { 
return itemImage; 
} 

public void setItemImage(String itemImage) { 
this.itemImage = itemImage; 
} 

public String getTotalquantity() { 
return totalquantity; 
} 

public void setTotalquantity(String totalquantity) { 
this.totalquantity = totalquantity; 
} 

} 

然后使用GSON库，你可以把它解析到模型对象

Gson gson = new Gson(); 
      Example modelObject = (Example) gson.fromJson(response, Example.class);

添加这种扶养

编译“融为一体。 google.code.gson：GSON：2.8.0'

，并使用这个分析器类。
