本文介绍了一个基于MVP(Model-View-Presenter)架构的应用实现案例，包括登录模块与商品展示模块的具体设计与实现过程。

//这是抽象类

public interface ContartIntface {

//view login
public interface LoginViewIntface{
    //注册的刷新方法
    public void showReg(String str);
    //登陆的刷新方法
    public void showLog(String str);
}


public interface  ProductIntface{
    //展示列表
    public void showProuduct(Object o);

    //展示搜索内容

    public void showSechProduct(Object o);
}

//p层的接口对象
public interface PersentIntface{
    public void pLogin(String phone , String pwd);
    public void pRegist(String phone , String pwd);
    public void pToRequest(int page);
    public void setContPrames(String cont,int page);
}

}

	//这个是Model的数据

            Gson gson = new Gson();
            Bean bean = gson.fromJson(json , Bean.class);
            myCallback.success(bean);
        }else {
