1.首先xUtils-2.4.4.jar包导入libs：

2.实现的.java文件有：

3.代码展示：
3.1、bean.class类

public class Bean {    public String title;    public String body;    public Bean() {        super();        // TODO Auto-generated constructor stub    }    public Bean(String title, String body) {        super();        this.title = title;        this.body = body;    }    public String getTitle() {        return title;    }    public void setTitle(String title) {        this.title = title;    }    public String getBody() {        return body;    }    public void setBody(String body) {        this.body = body;    }    @Override    public String toString() {        return "Bean [title=" + title + ", body=" + body + "]";    }}

3.2 MainActivity.class类

还有注意一点别忘了加网络权限
