MVP
写一个model接口
iModel
package com.example.yuekaolx1.LoginMVP.model;

import java.util.Map;

public interface iLoginModel {
void getData(String url, Map<String,String> parms,Cteanview cteanview);
interface Cteanview{
void ChengGong(Object oj);
void ShiBai();
}
}
在Model实现
Model
package com.example.yuekaolx1.LoginMVP.model;

import com.example.yuekaolx1.bean.LoginBean;
import com.example.yuekaolx1.network.HttpUtil;

import java.util.Map;

public class LoginModel implements iLoginModel{
@Override
public void getData(String url, Map<String, String> parms, final Cteanview cteanview) {
HttpUtil.getInstance().doPost(url,LoginBean.class,parms, new HttpUtil.NetCallBack() {
@Override
public void OnSuccess(Object oj) {
cteanview.ChengGong(oj);
}

        @Override
        public void OnFailure(Exception e) {

        }
    });
}

}
