在Android Studio中如何添加GSON 并使用GsonFormat快速实现实体类

方法一：

1.在Android Studio中按F4快捷键进入Project Structure

2点击+号

.

3.选择Library dependency

4.搜索GSON

5.添加进去

方法二：

在buil的.gradle中输入

compile 'com.google.code.gson:gson:2.6.2'

--------------------------------------------------------------------------------

综上就会看到添加成功

GsonFormat的安装

使用方法：

安装后重启android studio

然后在最上方code-Generate-GsonFormat

点OK就生成了

package com.example.myapplication;



/**
 * Created by 小新 on 2016/3/24.
 */
public class gson  {


    /**
     * name : 王五
     * gender : man
     * age : 15
     * height : 140cm
     */

    private String name;
    private String gender;
    private int age;
    private String height;

    public String getName() {
        return name;
    }

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

    public String getGender() {
        return gender;
    }

    public void setGender(String gender) {
        this.gender = gender;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    public String getHeight() {
        return height;
    }

    public void setHeight(String height) {
        this.height = height;
    }
}

简单使用Demo

1.比如获取的Json数据是

String Data = "{students:[{name:'魏祝林',age:25},{name:'阿魏',age:26}],class:'三年二班'}  ";

我们根据这个使用GsonFormat构建实体类

import com.google.gson.annotations.SerializedName;

import java.util.List;

/**
 * Created by 小新 on 2016/3/24.
 */
public class bean {

    /**
     * students : [{"name":"魏祝林","age":25},{"name":"阿魏","age":26}]
     * class : 三年二班
     */

    @SerializedName("class")
    private String classX;
    /**
     * name : 魏祝林
     * age : 25
     */

    private List students;

    public String getClassX() {
        return classX;
    }

    public void setClassX(String classX) {
        this.classX = classX;
    }

    public List getStudents() {
        return students;
    }

    public void setStudents(List students) {
        this.students = students;
    }

    public static class StudentsBean {
        private String name;
        private int age;

        public String getName() {
            return name;
        }

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

        public int getAge() {
            return age;
        }

        public void setAge(int age) {
            this.age = age;
        }
    }
}

2.然后使用Gson解析数据

String Data = "{students:[{name:'魏祝林',age:25},{name:'阿魏',age:26}],class:'三年二班'}  ";
Gson gson = new Gson();
bean b = gson.fromJson(Data,bean.class);
Log.v("Tag",b.getClassX());

可以解析出他的班级是三年二班
