JSON数组到特定类的ArrayList [重复]

Question

JSON

[
  {
    "id": 1,
    "name": "product new"
  },
  {
    "id": 2,
    "name": "test12345"
  },
  {
    "id": 3,
    "name": "product new"
  }
]

Java

 ArrayList<Product> products
 products = new Gson().fromJson(result.toString(), ArrayList<Product>.getClass());

如何将 JSON 数组转换为基于 Product 类的 ArrayList？

Answer 1

试试这个：

import com.google.gson.reflect.TypeToken;

ArrayList<Product> products  = new Gson().fromJson(results, new TypeToken<ArrayList<Product>>(){}.getType());;
