ViewInf

package com.example.yuekao1.view;

import com.example.yuekao1.bean.MyBean;

import java.util.List;

public interface ViewInf {
    public void updateUI(List<MyBean.DataBean.DatasBean> list);

ModelInf

package com.example.yuekao1.model;

import android.support.v7.app.AppCompatActivity;

import java.util.List;

public interface ModelInf {
    public void getData(AppCompatActivity activity,String url, CallBackListener listener);

CallBackListener

package com.example.yuekao1.model;

import com.example.yuekao1.bean.MyBean;

import java.util.List;

public interface CallBackListener {

Model
