首先是他用到的框架

compile 'com.github.bumptech.glide:glide:3.7.0'

compile 'com.jakewharton:butterknife:8.8.1'
annotationProcessor 'com.jakewharton:butterknife-compiler:8.8.1'
compile 'com.squareup.retrofit2:converter-gson:2.2.0'
compile 'com.squareup.retrofit2:adapter-rxjava2:2.2.0'
compile 'io.reactivex.rxjava2:rxandroid:2.0.1'
compile 'com.squareup.retrofit2:retrofit:2.2.0'
compile 'io.reactivex.rxjava2:rxjava:2.0.7'
compile 'com.squareup.okhttp3:okhttp:3.7.0'
compile 'com.squareup.okhttp3:logging-interceptor:3.6.0'
compile 'com.youth.banner:banner:1.4.9'

************************************************

网络请求net包下，作用：封装网络请求

public interface Api {

    public static final String HOST="http://120.27.23.105";
    public static final String XHOST="https://www.zhaoapi.cn";

}
**************************

public interface OnNetListner<T> {
//成功调用的方法
 void onSuccess(T t);
//失败调用的方法
 void onFailed(Exception e);
}

****************************************

//我用的是io的，还有ix的，别弄错了
import io.reactivex.Observable;
import retrofit2.http.POST;
import retrofit2.http.Query;

public interface RetrofitServer {

    @POST("/user/login")
    Observable<SingnBean> sign(@Query("mobile") String mobile, @Query("password") String pwd);

    @POST("/user/reg")
    Observable<RegisBean> regis(@Query("mobile") String mobile, @Query("password") String pwd);

    //首页广告（轮播图+京东秒杀+最底部的为你推荐）
    @POST("/ad/getAd")
    Observable<SgouyeBean> shouye();

    @POST("/product/getCatagory")
    Observable<FlleftBean> flleftbean();

    //商品分类
    @POST("/product/getCatagory")
    Observable<CatagoryBean> cara();

    //商品子分类
    @POST("/product/getProductCatagory")
    Observable<ProducatagoryBean> producatagory(@Query("cid") String cid);

    //当前子分类下的商品列表
    @POST("/product/getProducts")
    Observable<ProListBean> lisproduts(@Query("pscid") String pscid, @Query("source") String sourc);

    //.商品详情

    @POST("/product/getProductDetail")
    Observable<DetailBean> detail(@Query("pid") String pid, @Query("source") String source);

    //加入购物车
    @POST("/product/addCart")
    Observable<AddBean> adds(@Query("pid") String pid, @Query("uid") String uid, @Query("source") String source);

    //查询购物车
    @POST("/product/getCarts")
    Observable<CartsBean> carts(@Query("uid") String uid, @Query("source") String source);

    //搜索购物车
    @POST("/product/searchProducts")
    Observable<SpSouSbean> spss(@Query("keywords") String keywords, @Query("page") String page, @Query("source") String source);

 }
*********************************************

public class Retrofitss {
    private static OkHttpClient okHttpClient;
    private static RetrofitServer server;
    
  static {
        getOkHttpClient();
    }

    public static OkHttpClient getOkHttpClient() {
        if (okHttpClient == null) {
            synchronized (Retrofitss.class) {
                if (okHttpClient == null) {
                    okHttpClient = new OkHttpClient();
                }
            }
        }
        return okHttpClient;
    }

    public static RetrofitServer getServer() {
        if (server == null) {
            synchronized (OkHttpClient.class) {
                if (server == null) {
                    server = onCreate(RetrofitServer.class, Api.XHOST);
                }
            }

        }
        return server;
    }

    public static <T> T onCreate(Class<T> tClass, String url) {

        Retrofit retrofit = new Retrofit.Builder()
                .baseUrl(url)
                .addConverterFactory(GsonConverterFactory.create(new Gson()))
                .addCallAdapterFactory(RxJava2CallAdapterFactory.create())
                .client(okHttpClient)
                .build();
        return retrofit.create(tClass);

    }

}
//下面的是自己的项目一部分，主要看思路
****************************
在Model层的简单使用，看一下思路就可以了，下面的就是使用到项目中

public interface IAddModel {
    void getadd(String uid, String pid, String source, OnNetListner<AddBean> onNetListner);

}
********************************

public class AddModel implements IAddModel {
    @Override
    public void getadd(String uid, String pid, String source, final OnNetListner<AddBean> onNetListner) {
 // AddBean类里的数据是用https://www.zhaoapi.cn/product/addCart?pid=1&uid=这个地方写你自己登陆成功反回数据上的uid
//source=android公共参数
 Observable<AddBean> adds = Retrofitss.getServer().adds(pid, uid, source);

        adds.observeOn(AndroidSchedulers.mainThread())
                .subscribeOn(Schedulers.io())
                .subscribe(new Observer<AddBean>() {
                    @Override
                    public void onSubscribe(Disposable d) {

                    }

                    @Override
                    public void onNext(AddBean addBean) {
                        onNetListner.onSuccess(addBean);
                    }

                    @Override
                    public void onError(Throwable e) {
                        onNetListner.onFailed((Exception) e);
                    }

                    @Override
                    public void onComplete() {

                    }
                });
    }
}
**********************************
p层的使用

public class AddPrensenter {
    private IDetaileActivity activity;
    private final IAddModel model;

    public AddPrensenter(IDetaileActivity activity) {
        this.activity = activity;
        model = new AddModel();

    }
//防止内存泄漏
 public void ond(){
        if (activity!=null){
            activity=null;
        }
    }
    public void geta(String pid,String uid,String source){
        model.getadd(uid, pid, source, new OnNetListner<AddBean>() {
            @Override
            public void onSuccess(AddBean addBean) {
                if (activity!=null) {
                    activity.shoaw(addBean);
                }
            }

            @Override
            public void onFailed(Exception e) {

            }
        });

    }

}

****************************************c
v层的使用

public interface IDetaileActivity {
//这个类接口方法的逻辑就不写了，太多了
 void  show(DetailBean detailBean);

//我们用的是这个
 void shoaw(AddBean addBean);

}
