TwoActivity代码：

MyAdapter代码：

Bean类代码:

public class Bean {
    String name;
    String age;
    String img;
    public Bean(){

    }

    public String getName() {
        return name;

        this.name = name;
    }

    public String getAge() {
        return age;
    }

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

    public String getImg() {
        return img;
    }

    public void setImg(String img) {
        this.img = img;
