上回说到，Android实战-智慧城市(3)

软件设计

个人中心

    这一页没啥技术含量

关闭HomeActivity

    当点击”退出登录“按钮时关闭HomeAvtivity，并不是说什么时候都关闭HomeActivity
    在HomeActivity.java的类中声明类变量

1
public static HomeActivity homeActivity;

    在HomeActivity的init方法中给homeActivity变量赋值

1
homeActivity = HomeActivity.this;

用户信息的反序列化对象类

    GetInfoBean中的类全部都实现了Serializable接口，因为等下要把它传递给资料修改页
    GetInfoBean.java
