MVP实现RecyclerView

接口类

package com.bwie.month.contract;import com.bwie.month.model.RecyModel;public class RecyContract {    //View接口    public interface IRecyView {        public void setView(String s);    }    //Model接口    public interface IRecyModel {        public void getData(RecyModel.CCC ccc);    }    //PreSenter接口    public interface IRecyPresenter {        public void getData();    }}

Model
