How to use JSON retrieved from Webserver in Java Android App to create and use Objects dynamically
问题
我第一次正在构建一个带有Web服务器连接（使用Raspberry Pi 4上的LAMP）的Java Android应用程序。
有一个名为“products”的数据库表，其中包含所有产品（Product_id、productName、price）。我通过一个PHP API检索JSON数组。
在应用程序启动时，我想获取所有产品并将其创建为Java对象，这样我就可以在应用程序的一个片段中动态显示所有产品和价格。请注意，产品的数量和价格可能会更改，因此我需要这种方法来动态创建产品。
由于我以前从未做过这个，我陷入了困境。我知道如何在代码中获取响应，但我需要帮助将该响应转换为Java对象。您通常会如何处理？以下是我的JSON：
“status”：200，
“info”：[
{
“Product_id”：“1”，
“product”：“Coca Cola”，
“price”：“3”
}，
{
“Product_id”：“2”，
“product”：“Orange Juice”，
“price”：“2.5”
}，
{
“Product_id”：“3”，
“product”：“Apple Juice”，
“price”：“2.5”
}，
{
“Product_id”：“4”，
“product”：“Beer”，
“price”：“1.5”
}，
{
“Product_id”：“5”，
“product”：“Energy Drink”，
“price”：“3”
}，
{
“Product_id”：“6”，
“product”：“Gin Tonic”，
“price”：“5”
}，
{
“Product_id”：“7”，
“product”：“Water”，
“price”：“1”
}，
{
“Product_id”：“8”，
“product”：“Soda”，
“price”：“1”
}，
{
“Product_id”：“9”，
“product”：“Ticket”，
“price”：“30”
}
]

I am building a Java Android App with Webserver (Raspberry Pi 4 with LAMP) connection for the first time.
There's a db table "products" which holds all products (Product_id, productName, price). I am retrieving a JSON array though a PHP API.
On App launch, I want to get all products and create Java Objects out of them, so I can dynamically display all products and prices in a Fragment in my app. Note that number and price of products might change, so I need this approach to dynamically create the products.
Since I have never done this before, I am stuck. I know how to get a response in my code, but what I need help with is to turn that response into Java Objects. Any advice how you usually would do that?
Here's my JSON:
"status": 200,
"info": [
{
"Product_id": "1",
"product": "Coca Cola",
"price": "3"
},
{
"Product_id": "2",
"product": "Orange Juice",
"price": "2.5"
},
{
"Product_id": "3",
"product": "Apple Juice",
"price": "2.5"
},
{
"Product_id": "4",
"product": "Beer",
"price": "1.5"
},
{
"Product_id": "5",
"product": "Energy Drink",
"price": "3"
},
{
"Product_id": "6",
"product": "Gin Tonic",
"price": "5"
},
{
"Product_id": "7",
"product": "Water",
"price": "1"
},
{
"Product_id": "8",
"product": "Soda",
"price": "1"
},
{
"Product_id": "9",
"product": "Ticket",
"price": "30"
}
]
}
