【问题描述】：

如何使用 android 改造来使用这个 JSON？

"Pepsico": 
    "items": [
        
            "pro_name": "Lays indian mGic masala",
            "pro_price": "0"
        ,
        
            "pro_name": "amla hair amla",
            "pro_price": "0"
        
    ]
,
"Amul": 
    "items": [
        
            "pro_name": "Amul butter",
            "pro_price": "48"
        ,
        
            "pro_name": "Amul cow ghee",
            "pro_price": "270"
        ,
        
            "pro_name": "Amul Kool Elaine flavored milk",
            "pro_price": "20"
        ,
        
            "pro_name": "Amul plain cheese slices",
            "pro_price": "122"
        ,
        
            "pro_name": "pure ghee",
            "pro_price": "0"
        
    ]

预期的输出应该在嵌套的回收器视图中：

Category Name 1
Product1
Product2
Product3
Category Name 2
Product4
Product5
Product6
...

【参考方案1】：

试试下面的代码。

//if your product(Pepsico,Amul...etc) is also dynamic than you can parse you api response in hashmap dynamically
 HashMap<String,Product>()

//if your product is fixed then you should use this approach
class ApiResult
Product Pepsico;
Product Amul;

public Product getPepsico() 
    return Pepsico;


public void setPepsico(Product pepsico) 
    Pepsico = pepsico;


public Product getAmul() 
    return Amul;


public void setAmul(Product amul) 
    Amul = amul;




class  Product
ArrayList<HashMap<String,String>> items;

public ArrayList<HashMap<String, String>> getItems() 
    return items;


public void setItems(ArrayList<HashMap<String, String>> items) 
    this.items = items;

 

【讨论】：

产品也是动态的API

那么你应该采用第一种方法，直接在 hasmap 中序列化你的响应
