Question

我从json文件中获取数据，并希望在android中使用pojo类读取数据。我尝试了一些来自互联网的解决方案但我找不到确切的解决方案请帮帮我。

{  
"data":[  
    {  
        "id":"7",
        "parent_id":"3",

    }
]
}

到目前为止我的代码是什么。

jsonobject包含上面的json数据

Gson gson = new GsonBuilder().create();
Log.d("JSON",jsonObject.toString());
String jsonOutput = jsonObject.toString();

Type listType = new TypeToken<List<CatalogueDetail>>(){}.getType();
ArrayList<CatalogueDetail>      catalogueDetailslist = (List<CatalogueDetail>) gson.fromJson(jsonOutput, listType);

Answer 1

以下是Pojo课程的示例：

class List{
    CatalogueDetail[] data;
}

class CatalogueDetail{
    int id;
    int parent_id;
    String catalogue_code;
    String catalogue_name;
    String image;
    int image_code;
    String price;
    String description;
    String color;
    String fabric;
    String innner;
    String fabric_top;
    String fabric_bottom;
    String fabric_dupatta;
    String dupatta;
    String size;
    String length;
    String work;
    String style;
    String occasion;
    String stitch_unstitch;
    String blouse;
    String date;
    String main_category;
    String sub_category;
}

//Use this method to get data from your json
gson.fromJson(json, List.class);

Answer 2

根据您粘贴的json，您需要创建两个java类并将其转换为Example.java

Example ex = gson.fromJson(datastring, Example.class);

这两个课程如下。

-----------------------------------com.example.Example.java-----------------------------------

package com.example;

import java.util.ArrayList;
import java.util.List;
import javax.annotation.Generated;
import com.google.gson.annotations.Expose;
import com.google.gson.annotations.SerializedName;

@Generated("org.jsonschema2pojo")
public class Example {

@SerializedName("data")
@Expose
private List<Datum> data = new ArrayList<Datum>();


}

-----------------------------------com.example.Datum.java-----------------------------------

package com.example;

import javax.annotation.Generated;
import com.google.gson.annotations.Expose;
import com.google.gson.annotations.SerializedName;

public class Datum {

@SerializedName("id")
@Expose
private String id;
@SerializedName("parent_id")
@Expose
private String parentId;
@SerializedName("catalogue_code")
@Expose
private String catalogueCode;
@SerializedName("catalogue_name")
@Expose
private String catalogueName;
@SerializedName("image")
@Expose
private String image;
@SerializedName("image_code")
@Expose
private String imageCode;
@SerializedName("price")
@Expose
private String price;
@SerializedName("description")
@Expose
private String description;
@SerializedName("color")
@Expose
private String color;
@SerializedName("fabric")
@Expose
private String fabric;
@SerializedName("innner")
@Expose
private String innner;
@SerializedName("fabric_top")
@Expose
private String fabricTop;
@SerializedName("fabric_bottom")
@Expose
private String fabricBottom;
@SerializedName("fabric_dupatta")
@Expose
private String fabricDupatta;
@SerializedName("dupatta")
@Expose
private String dupatta;
@SerializedName("size")
@Expose
private String size;
@SerializedName("length")
@Expose
private String length;
@SerializedName("work")
@Expose
private String work;
@SerializedName("style")
@Expose
private String style;
@SerializedName("occasion")
@Expose
private String occasion;
@SerializedName("stitch_unstitch")
@Expose
private String stitchUnstitch;
@SerializedName("blouse")
@Expose
private String blouse;
@SerializedName("date")
@Expose
private String date;
@SerializedName("main_category")
@Expose
private String mainCategory;
@SerializedName("sub_category")
@Expose
private String subCategory;


}

尝试以下代码......

public class TestPojo {

    private List<DataEntity> data;

    public void setData(List<DataEntity> data) {
        this.data = data;
    }

        return data;
    }

    public static class DataEntity {

使用Gson进行转换

TestPojo pj = new Gson().fromJson(<Your JSON String>, TestPojo.class);

希望这是有效的。

如何在android中使用GSON库读取下面的json数据？
