如何使用GSON / JSON将字符串数组转换为对象？ [英] How to convert string array to object using GSON/ JSON?

问题描述

我有这样的json：

I have a json like this:

[
  [
    "Passport Number",
    "NATIONALITY",
    "REASONS"
  ],
  [
    "SHAIS100",
    "INDIA",
    ""
  ],
  [
    "",
    "",
    "Agent ID is not matched."
  ],
  [
    "",
    "",
    ""
  ]
]

我想把它填充到 ArrayList< String []> ，请告诉我怎么办？

I want to populate this to ArrayList<String[]>,Please tell me how to do?

空字符串不应该转换为空。

And empty strings should not convert as null.

推荐答案

1.-首先创建 Gson object：

1.- First create the Gson object:

Gson gson = new Gson();

2.-然后获取记者类型 （ List< String []> ）（注意，由于Java的类型擦除）： p>

2.- Then get the correspondent Type for your List<String[]> (Note that you can't do something like List<String[]>.class due to Java's type erasure):

Type type = new TypeToken<List<String[]>>() {}.getType();

3.-最后将JSON解析为类型 code>：



3.- Finally parse the JSON into a structure of type type:

List<String[]> yourList = gson.fromJson(yourJsonString, type);
