java - 如何反序列化 Array google-gson 中的 Array

Question

我有这样的 JSON:

{
 "Answers":
 [
  [
   {"Locale":"Ru","Name":"Name1"},
   {"Locale":"En","Name":"Name2"}
  ],
  [
   {"Locale":"Ru","Name":"Name3"},
   {"Locale":"En","Name":"Name4"}
  ]
 ]
}

如您所见，我在数组中有数组。如何在 Android ( https://code.google.com/p/google-gson/ ) 上使用 google-gson 库将此类 JSON 结构反序列化为对象？

Answer 1

Json 格式后我们得到这样的东西:

我的对象

public class MyObject {
public List<List<Part>> Answers;

public List<List<Part>> getAnswers() {
    return Answers;
  }
}

部分

public class Part {
private String Locale;
private String Name;

public String getLocale() {
    return Locale;
}
public String getName() {
    return Name;
}

}

主要

public static void main(String[] args) {
    String str = "    {" + 
            "       \"Answers\": [[{" + 
            "           \"Locale\": \"Ru\"," + 
            "           \"Name\": \"Name1\"" + 
            "       }," + 
            "       {" + 
            "           \"Locale\": \"En\"," + 
            "           \"Name\": \"Name2\"" + 
            "       }]," + 
            "       [{" + 
            "           \"Locale\": \"Ru\"," + 
            "           \"Name\": \"Name3\"" + 
            "       }," + 
            "       {" + 
            "           \"Locale\": \"En\"," + 
            "           \"Name\": \"Name4\"" + 
            "       }]]" + 
            "    }";

    Gson gson = new Gson();

    MyObject obj  = gson.fromJson(str, MyObject.class);

    List<List<Part>> answers = obj.getAnswers();

    for(List<Part> parts : answers){
        for(Part part : parts){
            System.out.println("locale: " + part.getLocale() + "; name: " + part.getName());
        }
    }

}

输出:

locale: Ru; name: Name1
locale: En; name: Name2
locale: Ru; name: Name3
locale: En; name: Name4
