Question

您好我已经使用GSON解析简单的jsonobjects。但这次我的回复数据非常复杂。所以我很难解析那些数据。我的数据看起来像：

[{"creator":"1", "users":[{"userName":"nilesh", "userAge":"25"},{"userName":"Me", "userAge":"25"}]},
{"creator":"2", "users":[{"userName":"nilesh", "userAge":"25"},{"userName":"Me", "userAge":"25"}]}
]

所以我用以下方式编写了一个解析类

public class UserData 
{
    @SerializedName("creator")
    public String creator;

    public List<Users> users;

    public static class Users
    {
        @SerializedName("userName")
        public String userName;

        @SerializedName("userAge")
        public String userAge;
    }
}

但这不起作用。我做错了什么需要一些关于这个解析的帮助。谢谢。

我试着像这样解析：

Gson gson = new Gson();
UserData users = gson.fromJson(result, UserData.class);

它给我这样的错误：

 01-04 12:36:04.337: E/AndroidRuntime(15651): Caused by: com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected BEGIN_OBJECT but was BEGIN_ARRAY at line 1 column 2

Answer 1

这是因为您发布的JSON无效。
它应该是这样的下面发布的json是你的json有效。

[
{
    "creator": "1",
    "users": [
        {
            "userName": "nilesh",
            "userAge": "25"
        },
        {
            "userName": "Me",
            "userAge": "25"
        }
    ]
},
{
    "creator": "2",
    "users": [
        {
            "userName": "nilesh",
            "userAge": "25"
        },
        {
            "userName": "Me",
            "userAge": "25"
        }
    ]
}
]

您发布的json包含以下几点的错误

users [应为"users" :[
userAge :应为"userAge":

Answer 2

这就是我要找的东西

public class UserData 
{
    public String creator;

    public List<Users> user;

    public class Users
    {
        public String userName;
        public String userAge;
    }
}

我按照以下方式解析

Gson gson = new Gson();
Type type = new TypeToken<List<UserData>>(){}.getType();
List<UserData > objList = gson.fromJson(result, type);

用GSON解析复杂的JsonArray
