android - 关于JSON格式转为JavaBean？

Question

[
    {
        "url": "http://www.baidu.com",
        "title": "测试1",
        "type": 1,
        "pic": "null"
    },
    {
        "url": "http://www.baidu.com",
        "title": "测试2",
        "type": 2,
        "pic": "null"
    }
]

例如如上的JSON格式，其对应的JavaBean是什么样子的？
[]括号括起来的应该是对应List，但是其List并没有一个key，这该怎么弄？
Gson解析就报这里错了。。。

Answer 1

This is a problem of converting JOSN array to List. For example, the object is as follows

 public class TestBean{
     private String url;
     private String title;
     private String type;
     private String pic;
     //省略getter,setter
}

The json string you gave you converted into a list should be:
List<TestBean> list = gson.fromJson(str, new TypeToken<List<TestBean>>(){}.getType());

Answer 2

public class Test{
    
    private List<TestBean> tests;
    //省略getter,setter
    
    public static class TestBean{
         private String url;
         private String title;
         private String type;
         private String pic;
         //省略getter,setter
    }
}

//这就能得到如题所示的json了
JSON.toJSON(Test.getTests())

Answer 3

In json, [] represents an array and {} represents an object. In the above structure, there are two objects in the array, and each object has four properties. The data structure is

List<Object> list = new ArrayList<Object>();
