MVP+Retrofit2+Okhttp3

先写一个baseAPI

//存储地址

    //Retrofit_banner
    public static final String Retrofit_Banner = "mobile/listSlides.do";
    //Retrofit_login
    public static final String Retrofit_Login = "mblogin.do";
}

RetrofitContract

        void bannerData(List<banner> list);

    }

    abstract class presenter extends BasePresenter<View>{

        this.context = context;
        //this.mModel = mModel;
        this.mView = mView;
    }

}

　　

//用来回调接口成功失败
public interface BaseView {
    void showMsg(String msg);
    void showLoading();
    void stopLoading();
    //void success(Object o,int type);
    void failure();

//存放Demo模块，API
