Retrifit工具类：

接口类：

public class Constants {
    public static String Base_url="https://www.zhaoapi.cn/";
    public static String login_url="user/login";
}

请求网络接口的封装接口Service类：

import com.example.admin.xiaoshixun_retrofit_rxjava_mvp.Entity.BaseUser;
import com.example.admin.xiaoshixun_retrofit_rxjava_mvp.Entity.User;

import java.util.Map;

import retrofit2.Call;
import retrofit2.http.FieldMap;
import retrofit2.http.FormUrlEncoded;
import retrofit2.http.POST;
import retrofit2.http.Url;


/**
 * Created by dell on 2018/1/30.
 */

public interface LoginService {
    @POST
    @FormUrlEncoded
    Call> postRetrofit(@Url String url, @FieldMap Map map);
}

Entity类：

public class BaseUser<T> {
    private String msg;
    private String code;
    private T      data;

    public void setMsg(String msg) {
        this.msg = msg;
    }

    public void setCode(String code) {
        this.code = code;
    }

    public void setData(T data) {
        this.data = data;
    }

    public String getMsg() {
        return msg;
    }

    public String getCode() {
        return code;
    }

    public T getData() {
        return data;
    }
}

Entity下User类：

public class User extends BaseUser {


    private Object age;
    private String appkey;
    private String appsecret;
    private String createtime;

Model：

public interface IModel {

    //请求网络，为登录做准备
    void LoginModel(Map map,OnLoginListener onLoginListener);

}

public class ModelImpl implements IModel {

    @Override
    public void LoginModel(Map map, final OnLoginListener onLoginListener) {
        //创建OkhttpClient
        OkHttpClient client = new OkHttpClient.Builder().build();
        //构造链式调用
        new RetrofitUtils
                .Builder()
                .client(client)
                .addCallAdapterFactory(RxJava2CallAdapterFactory.create())
                .addConverterFactory(GsonConverterFactory.create())
                .build()
                .getTsetService()
                .postRetrofit(Constants.login_url,map)
                .enqueue(new Callback>() {
                    //请求成功
                    @Override
                    public void onResponse(Call> call, Response> response) {
                        Log.e( "onResponse: ",response.body().getMsg() );
                        onLoginListener.Success(response.body());
                    }

                    //请求失败
                    @Override
                    public void onFailure(Call> call, Throwable t) {
                        Log.e( "onFailure: ", t.toString());
                        onLoginListener.Error(t.toString());
                    }
                });

    }
}

请求网络监听：

public interface OnLoginListener {
    //成功的方法
    void Success(BaseUser baseUser);
    //失败的方法
    void Error(String error);
}

Precenter：

public interface IPrecenter {
    //联系mv
    void LoginPrecenter(IModel iModel, IView iView);
    //mvp解绑
    void Destory();

}

public class PrecenterImpl implements IPrecenter {
    private IView iView;

    @Override
    public void LoginPrecenter(IModel iModel, final IView iView) {
        this.iView = iView;

        //获取用户名密码做验证
        String mobile = iView.getMobile();
        String password = iView.getpassword();

        if (mobile.length() == 0) {

            iView.MobileError("手机格式不正确");
        }
        if (password.length() == 0) {
            iView.PasswordError("密码格式不正确");
        }

        Map map = new HashMap<>();
        map.put("mobile", mobile);
        map.put("password", password);
        iModel.LoginModel(map, new OnLoginListener() {
            @Override
            public void Success(BaseUser baseUser) {
                String code = baseUser.getCode();
                if (code.equals("0")) {
                    iView.LoginSuccess(baseUser);
                } else {
                    iView.failure(baseUser.getMsg());
                }
            }

            @Override
            public void Error(String error) {
                iView.failure(error);

            }
        });
    }

    @Override
    public void Destory() {

        if (iView != null) {
            iView = null;
        }
    }
}

View：

public interface IView {
    //获取手机号
    String getMobile();
    //获取密码
    String getpassword();

    //手机号格式错误
    void MobileError(String error);
    //密码格式错误
    void PasswordError(String error);
    //网络请求成功，登录成功
    void LoginSuccess(BaseUser baseUser);
    //网络请求失败，登录失败
    void LoginError(BaseUser baseUser);
    //网络请求失败
    void failure(String error);
}

public class MainActivity extends AppCompatActivity implements IView {
    @BindView(R.id.ed1)
    EditText ed1;
    @BindView(R.id.ed2)
    EditText ed2;
    private PrecenterImpl p;

    @Override

        p = new PrecenterImpl();

    }

    @OnClick(R.id.login)
    public void loginButton(View view){
        //调中间人
        p.LoginPrecenter(new ModelImpl(),this);

    }

    @Override
    public String getMobile() {
        String trim = ed1.getText().toString().trim();
        return trim;
    }

    @Override
    public String getpassword() {
        String trim = ed2.getText().toString().trim();
        return trim;
    }

    //手机格式不正确
    @Override
    public void MobileError(String error) {
        Toast.makeText(this, error, Toast.LENGTH_SHORT).show();
    }
    //密码格式不正确
    @Override
    public void PasswordError(String error) {
        Toast.makeText(this, error, Toast.LENGTH_SHORT).show();
    }

    //请求网络成功，登录成功
    @Override
    public void LoginSuccess(BaseUser baseUser) {
