首先我们要做的是添加各种依赖：
先看我的build.gradle

apply plugin: 'com.android.application'

android {
    compileSdkVersion 26
    buildToolsVersion "26.0.2"

    defaultConfig {
        applicationId "com.example.mvprecyclerviewretrofitrxjavademo"
        minSdkVersion 15
        targetSdkVersion 26
        versionCode 1
        versionName "1.0"

        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"

    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile 'com.android.support:appcompat-v7:26.+'
    compile 'com.android.support.constraint:constraint-layout:1.0.2'
    testCompile 'junit:junit:4.12'
    compile 'com.squareup.retrofit2:retrofit:2.0.0-beta4'
    compile 'com.squareup.retrofit2:converter-gson:2.0.0-beta4'
    compile 'com.squareup.okhttp3:okhttp:3.1.2'
    compile 'com.squareup.retrofit2:adapter-rxjava:2.0.0-beta4'
    compile 'io.reactivex:rxjava:1.1.0'
    compile 'io.reactivex:rxandroid:1.1.0'
    compile 'com.google.code.gson:gson:2.6.2'
    compile 'com.android.support:recyclerview-v7:26.0.0-alpha1'
    compile 'com.facebook.fresco:fresco:0.11.0'
}

再然后我用的是MVP模式写的Recyclerview实现
Recyclerview在MainActivity中显示

我们运用Retrofit和Rxjava 要添加一个包：retrofit
retrofit里面有一个接口：RetroAPI

package com.example.mvprecyclerviewretrofitrxjavademo.retrofit;

import com.example.mvprecyclerviewretrofitrxjavademo.bean.RetroBean;

import okhttp3.OkHttpClient;
import retrofit2.Retrofit;
import retrofit2.adapter.rxjava.RxJavaCallAdapterFactory;
import retrofit2.converter.gson.GsonConverterFactory;
import retrofit2.http.GET;
import rx.Observable;

/**
 * 作者：author
 * 说明：
 */

public interface RetroAPI {
    @GET("v1/restserver/ting?method=baidu.ting.billboard.billList&type=1&size=10&offset=0")
    Observable<RetroBean> getRetro();
    OkHttpClient CLIENT=new OkHttpClient.Builder()
            .addInterceptor(new LoggingInterceptor())
            .build();
    Retrofit RETROFIT=new Retrofit.Builder()
            .baseUrl("http://tingapi.ting.baidu.com/")
            .addCallAdapterFactory(RxJavaCallAdapterFactory.create())
            .addConverterFactory(GsonConverterFactory.create())
            .client(CLIENT)
            .build();
    RetroAPI RETRO_API=RETROFIT.create(RetroAPI.class);
}

可以看出我们在API里面创建了Retrofit,以及ok的拦截器
那么我们给出的拦截器(网络拦截器)实例是：LoggingInterceptor
这个实例是不需要我们写的，但是没有加网络拦截器的话，就会请求不到地址（其他的接口可能没有此拦截器）

package com.example.mvprecyclerviewretrofitrxjavademo.retrofit;

import android.os.Build;

import java.io.IOException;

import okhttp3.Interceptor;
import okhttp3.Request;
import okhttp3.Response;

/**
 * 网络拦截器
 */

public class LoggingInterceptor implements Interceptor {
    private static final String UA = "User-Agent";

    @Override
    public Response intercept(Chain chain) throws IOException {
        Request request = chain.request()
                .newBuilder()
                .addHeader(UA, makeUA())
                .build();
        return chain.proceed(request);
    }

    private String makeUA() {
        String s = Build.BRAND + "/" + Build.MODEL + "/" + Build.VERSION.RELEASE;
        return Build.BRAND + "/" + Build.MODEL + "/" + Build.VERSION.RELEASE;
    }

}

MyApp: 初始化fresco 别忘了在清单文件里加入name
以及在清单文件里加入网络权限*******

package com.example.testzhoukaotablayoutretrofit;

import android.app.Application;

import com.facebook.drawee.backends.pipeline.Fresco;

/**

public class MyApp extends Application {
    @Override
    public void onCreate() {
        super.onCreate();
        Fresco.initialize(this);
    }
}

Model:
IshowModel

package com.example.mvprecyclerviewretrofitrxjavademo.model;

import com.example.mvprecyclerviewretrofitrxjavademo.bean.RetroBean;

import java.util.List;

/**

public interface IshowModel {
    public void showData(Callback callback);
    interface Callback{
        void complate(List<RetroBean.SongListBean> listb);
    }
}

ShowModel:

public class showModel implements IshowModel {
    @Override
    public void showData(final Callback callback) {
        RetroAPI.RETRO_API.getRetro()
                .subscribeOn(Schedulers.io())
                .observeOn(AndroidSchedulers.mainThread())
                .subscribe(new Observer<RetroBean>() {
                    @Override
                    public void onCompleted() {

                    }

                    @Override
                    public void onError(Throwable e) {

                    }

                    @Override
                    public void onNext(RetroBean retroBean) {
                        List<RetroBean.SongListBean> list=retroBean.getSong_list();
                        callback.complate(list);
                    }
                });
    }
}

view:

package com.example.mvprecyclerviewretrofitrxjavademo.view;

import com.example.mvprecyclerviewretrofitrxjavademo.bean.RetroBean;

import java.util.List;

/**
 * 作者：author

public interface IshowView {
    public void getData(List<RetroBean.SongListBean> listb);
}

presenter:
Ipresenter接口:

package com.example.testzhoukaotablayoutretrofit.presenter;

/**

public interface Ipresenter <T>{
    void attach(T view);
    void detach();

            default:
                break;
        }
    }
}

Mvp解绑需要一个Base类来实现：
BaseActivity:

package com.example.mvprecyclerviewretrofitrxjavademo;

import android.app.Activity;
import android.os.Bundle;
import android.support.annotation.Nullable;

import com.example.mvprecyclerviewretrofitrxjavademo.presenter.Ipresenter;

/**
 * 作者：author
 * 说明：
 */

public abstract class BaseActivity<T extends Ipresenter> extends Activity{
    T presenter;
    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        createpresenter();
    }

    protected abstract void createpresenter();

    @Override
    protected void onDestroy() {
        super.onDestroy();
        if(presenter!=null){
            presenter.detach();
        }
    }
}

最后把布局show一下：
MainActivity的layout:

<?xml version="1.0" encoding="utf-8"?>

    xmlns:app="http://schemas.android.com/apk/res-auto"

    </LinearLayout>
