如何抓住JSON数组并使用gson来解析每个json对象？ （改型） [英] How to grab JSON Array and use gson to parse each json object? (Retrofit)

问题描述

我用我的json Objects返回了一个结果数组，我试图用我的customObjectResponse类来提取每个对象中的每个字段......它期望一个对象的问题，那么我该如何编辑我的类以允许它接受一个对象数组，以便能够调用每个对象的字段......我很困惑，需要添加什么：

这是一个正在传递的响应示例：

  [{itemId：'dfsdfsdf343434'，
名称：'tests'，
图片：'6976-7jv8h5.jpg'，
描述：'testy。'，
 dateUpdated：1395101819，
}] 
  

这是我的响应对象类：

  public class ObjResponse {
 private String itemId; 
私人字符串名称; 
私人字符串图片; 
 
私人字符串描述; 
 
私人字符串位置; 
 private int dateUpdated; 
 
 private String msg; 
 
 
 
 
 // gridview构造函数
 public ObjResponse（String picture）{
 this.picture = picture; 
 
 
 //公共构造函数
 public ObjResponse（）{
 
} 
 
 public String getItemId（）{
返回itemId; 
} 
 
 public void setItemId（String itemId）{
 this.itemId = itemId; 
} 
 
 public String getName（）{
 return name; 
} 
 
 public void setName（String name）{
 this.name = name; 
} 
 
 public String getPicture（）{
 return picture; 
} 
 
 public void setPicture（String picture）{
 this.picture = picture; 
} 
 
 
 public String getLocation（）{
 return location; 
} 
 
 public void setLocation（String location）{
 this.location = location; 
} 
 
 
 public String getDescription（）{
 return description; 
} 
 
 public void setDescription（String description）{
 this.description = description; 
} 
 
 
 
 public int getDateUpdated（）{
 return dateUpdated; 
} 
 
 public void setDateUpdated（int dateUpdated）{
 this.dateUpdated = dateUpdated; 
} 
 
 
 
 
 public String getMsg（）{
 return msg; 
} 
 
} 
  

我在尝试的是不工作，即使我将这些类分隔到自己的文件中：

pre code传入的数据
items：[{ obj1：A，obj2：[c，d]}，{etc ...}]


公共类响应{

公开课列表< Custom> {
私人列表<自定义>项目;
}

公共类自定义{
private String obj1;
私人列表< Obj2> obj2的;
}

public Class Obj2 {
private String letters;
}
}

解决方案

I最后只是在回调中调用了customObject的列表，并完成了工作......

  new Callback< List< ObjResponse> ;>（）{
  

I am returning an array of results with my json Objects, and I am trying to use my customObjectResponse class to pull out each of the fields within each of the objects... the problem it is expecting an object so how do I edit my class to allow it to take in an array of object to be able to then call the fields of each object... I am confused as to what needs to be added:

Here is a response example of what is being passed to be used:

[ { itemId: 'dfsdfsdf343434',
       name: 'tests',
       picture: '6976-7jv8h5.jpg',
       description: 'testy.',
       dateUpdated: 1395101819,
       } ]

Here is my response Object Class:

public class ObjResponse{
    private String itemId;
    private String name;
    private String picture;

    private String description;

    private String location;
    private int dateUpdated;

    private String msg;




    //gridview constructor
    public ObjResponse(String picture) {
        this.picture = picture;
    }

    //public constructor
    public ObjResponse() {

    }

    public String getItemId() {
        return itemId;
    }

    public void setItemId(String itemId) {
        this.itemId = itemId;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getPicture() {
        return picture;
    }

    public void setPicture(String picture) {
        this.picture = picture;
    }


    public String getLocation() {
        return location;
    }

    public void setLocation(String location) {
        this.location = location;
    }


    public String getDescription() {
        return description;
    }

    public void setDescription(String description) {
        this.description = description;
    }



    public int getDateUpdated() {
        return dateUpdated;
    }

    public void setDateUpdated(int dateUpdated) {
        this.dateUpdated = dateUpdated;
    }




    public String getMsg() {
        return msg;
    }

}

what I am trying, but is not working, even if I separate the classes into their own files:

Data passed in:
items: [{obj1: "A", obj2: ["c", "d"]}, {etc...}]


public class Response {

        public class List<Custom> {
                private List<Custom> items;
        }

        public class Custom {
                private String obj1;
                private List<Obj2> obj2;
        }

        public Class Obj2 {
                private String letters;
        }
}

解决方案

I ended up just calling in the callback a list of the customObject and it did the job...

new Callback<List<ObjResponse>>() {
