改造-JSON数组解析 [英] Retrofit - JSON Array Parsing

问题描述

我正在使用Retrofit解析JSON Array，其中JSON数组如下:

I am parsing JSON Array using Retrofit, where JSON Array looks like:

"hobbies": [ "Music", "Reading"]

这是我的JSON的样子:

{
    "type":"success",
    "value":[
        {
            "id":1,
            "title":"Title - 1",
         "name":{
            "first":"First - 1",
            "last":"Last - 1"
         },
            "hobbies":[
                "Writing Code - 1",
            "Listening Music - 1"
            ]
        },
       .....
    ]
}

Value.java

private List<String> hobbies = new ArrayList<String>();

Adapter.java

viewHolder.hobbies.setText(value.getHobbies().toString());

运行程序时，我是getting data，如下所示:

And when I run my program, I am getting data as seen below:

[Music, Reading]

所以，问题是Why，我的输出也得到了[].

So, Question is Why I am getting [] as well in output.

Value.java

public class Value {

    @SerializedName("id")
    @Expose
    private Integer id;

    @SerializedName("title")
    @Expose
    private String title;

    @SerializedName("hobbies")
    @Expose
    private List<String> hobbies = new ArrayList<String>();

    @SerializedName("name")
    @Expose
    private Name name;

    .....

    public List<String> getHobbies() {
        return hobbies;
    }

    public void setHobbies(List<String> hobbies) {
        this.hobbies = hobbies;
    }
}

Service.java

public interface Service {

   @GET("/demo_retrofit.json")
   Observable<Master> getMaster();
}

推荐答案

实际上value.getHobbies();直接使用[ ]返回List.更好的iterate它并使用StringBuilder

Actually value.getHobbies(); directly return an List with [ ]. better iterate it and show by using StringBuilder
