MVP登录注册、跳转

这是一个用MVP模式写的登录注册，包括手机号、密码验证，登陆成功后跳转到商品列表页面。先看一下效果：正如我们看到的一样，在登陆界面点击注册会跳转到注册页面，注册成功后会跳转到登录界面，登录成功后会跳转到商品列表界面。在登录注册的过程中手机号和密码使用正则表达式进行了验证，使用OKhttp请求的网络，RecyclerView展示的数据，Springview执行上拉刷新和下拉加载。下面

这是一个用MVP模式写的登录注册，包括手机号、密码验证，登陆成功后跳转到商品列表页面。先看一下效果：

正如我们看到的一样，在登陆界面点击注册会跳转到注册页面，注册成功后会跳转到登录界面，登录成功后会跳转到商品列表界面。在登录注册的过程中手机号和密码使用正则表达式进行了验证，使用OKhttp请求的网络，RecyclerView展示的数据，Springview执行上拉刷新和下拉加载。下面看代码：
