  1 | ## Sample 简介
  2 | 
  3 | 一个简单的结合 Retrofit 和 RxJava 框架实现 MVVM 架构的例子。
  4 | 
  5 | 最近在研究 [Kotlin](https://github.com/githubhaohao/JavaToKotlin) for Android，做了一个基于 Clean 架构以及 Retrofit ， RxKotlin ， Dagger 框架实现的 Kotlin for Android App ，更多详情请[戳这里](https://github.com/githubhaohao/DoubanBook)。

 10 | 
 11 | [Demo 下载](https://github.com/githubhaohao/MVVMRxJavaRetrofitSample/blob/master/demo.apk)
 12 | 
 13 | ## 准备知识
 14 | ### MVC
 15 | ![mvc](https://github.com/githubhaohao/ImageRoom/blob/master/Images/mvvm/mvc.PNG?raw=true)
 16 | 
 17 | - **视图（View）**：用户界面。
 18 | - **控制器（Controller）**：业务逻辑
 19 | - **模型（Model）**：数据保存
 20 | 
 21 | ---
 22 | 1. View 传送指令到 Controller
 23 | 2. Controller 完成业务逻辑后，要求 Model 改变状态
 24 | 3. Model 将新的数据发送到 View，使用户得到反馈
 25 | 
 26 | **缺陷**:View 和 Model 是相互可知，耦合性大，像 Activity 或者 Fragment 既是 Controller 层，又是 View 层，造成工程的可扩展性可维护性非常差。
 27 | 
 28 | ### MVP
 29 | ![mvp](https://github.com/githubhaohao/ImageRoom/blob/master/Images/mvvm/mvp.png?raw=true)
 30 | 
 31 | 在 MVP 设计架构中，Controller 变成了 Presenter。
 32 | 
 33 | 1. 各层之间的通信，都是双向的。
 34 | 2. View 与 Model 不直接发生联系，都通过 Presenter 进行间接通信。
 35 | 3. Model 层与 Presenter 层，Presenter 层与 View 层之间通过接口建立联系。
 36 | 
 37 | 采用 MVP 设计架构，Activity 与 Fragment 只位于 View 层。
 38 | 
 39 | **MVP 的缺陷在于**:由于我们使用了接口的方式去连接 View 层和  Presenter 层，这样就导致了一个问题，当你的页面逻辑很复杂的时候，你的接口会有很多，如果你的 app 中有很多个这样复杂的页面，维护接口的成本就会变的非常的大。
 40 | 
 41 | ### MVVM
 42 | ![MVVM](https://github.com/githubhaohao/ImageRoom/blob/master/Images/mvvm/mvvp.PNG?raw=true)
 43 | 
 44 | MVVM 模式将 Presenter 改名为 ViewModel，基本上与 MVP 模式完全一致。
 45 | **区别在于**: View 层与 ViewModel 层通过`DataBinding`相互绑定，View的变动，自动反映在 ViewModel，反之亦然。
 46 | 
 47 | ### [RxJava](https://github.com/ReactiveX/RxJava )
 48 | 
 49 | RxJava 在 GitHub 主页上的自我介绍是 "a library for composing asynchronous and event-based programs using observable sequences for the Java VM"（一个在 Java VM 上使用可观测的序列来组成异步的、基于事件的程序的库）。
 50 | 
 51 | RxJava 本质上是一个异步操作库，是一个能让你用极其简洁的逻辑去处理繁琐复杂任务的异步事件库。
 52 | 
 53 | 简而言之，RxJava 可以用几个关键字概括：**简洁**，**队列化**，**异步**。
 54 | 
 55 | ### [Retrofit](https://github.com/square/retrofit)
 56 | 
 57 | ![retrofit](https://github.com/githubhaohao/ImageRoom/blob/master/Images/mvvm/android-libs-retrofit-1-638.jpg?raw=true)
 58 | 
 59 | 一个 Android 和 Java 上 HTTP 库（利用注解和 okhttp 来实现和服务器的数据交互）。
 60 | 
 61 | [**Retrofit 官方文档:http://square.github.io/retrofit/**](http://square.github.io/retrofit/)
 62 | 
 63 | ### [DataBinding](https://developer.android.com/topic/libraries/data-binding/index.html)
 64 | 
 65 | ![data-binding](https://github.com/githubhaohao/ImageRoom/blob/master/Images/mvvm/data_binding.png?raw=true)
 66 | 
 67 | 在今年的 Google IO 2015 中，Google 在 support-v7 中新增了 Data Binding，使用 Data Binding 可以直接在布局的 xml 中绑定布局与数据，从而简化代码，Android Data Binding 是Android 的 MVVM 框架。因为 Data Binding 是包含在 support-v7 包里面的，所以可以向下兼容到最低 Android 2.1 (API level 7+).
 68 | 
 69 | ## 实践
 70 | 
 71 | 嫌代码不够高亮？请移步博客[http://haohaochang.cn](http://haohaochang.cn/2017/02/12/MVVM%EF%BC%8CRxJava%E5%92%8CRetrofit%E7%9A%84%E4%B8%80%E6%AC%A1%E5%AE%9E%E8%B7%B5/)
 72 | 
 73 | 直接上代码。
 74 | 
 75 | ### 依赖的第三方类库
 76 | 
 77 | ```gradle
 78 |     compile 'io.reactivex:rxjava:1.1.0'
 79 |     compile 'io.reactivex:rxandroid:1.1.0'
 80 |     compile 'com.squareup.retrofit2:retrofit:2.0.0-beta4'
 81 |     compile 'com.squareup.retrofit2:converter-gson:2.0.0-beta4'
 82 |     compile 'com.squareup.retrofit2:adapter-rxjava:2.0.0-beta4'
 83 |     compile 'com.github.bumptech.glide:glide:3.7.0'
 84 | ```
 85 | 
 86 | ### API
 87 | 
 88 | `https://api.douban.com/v2/movie/top250?start=0&count=20`
 89 | 
 90 | ### 引入DataBinding
 91 | 
 92 | ```gradle
 93 | android {
 94 |     ......
 95 | 
 96 |     dataBinding {
 97 |         enabled = true
 98 |     }
 99 | }
100 | 
101 | ```
102 | 
103 | ### 工程目录结构

522 | **DouBanMovieService.java**
523 | 
524 | ```java
525 | public interface DouBanMovieService {
526 |     String BASE_URL = "https://api.douban.com/v2/movie/";
527 | 
528 |     @GET("top250")
529 |     Observable<Response<List<Movie>>> getMovies(@Query("start") int start, @Query("count") int count);
530 | }
531 | ```
532 | **RetrofitHelper.java**
533 | ```java
534 | public class RetrofitHelper {
535 |     private static final int DEFAULT_TIMEOUT = 10;
536 |     private Retrofit retrofit;
537 |     private DouBanMovieService movieService;
538 |     OkHttpClient.Builder builder;
539 | 
540 |     /**
541 |      * 获取RetrofitHelper对象的单例
542 |      * */
543 |     private static class Singleton {
544 |         private static final RetrofitHelper INSTANCE = new RetrofitHelper();
545 |     }
546 | 
547 |     public static RetrofitHelper getInstance() {
548 |         return Singleton.INSTANCE;
549 |     }
550 | 
551 |     public RetrofitHelper() {
552 |         builder = new OkHttpClient.Builder();
553 |         builder.connectTimeout(DEFAULT_TIMEOUT, TimeUnit.SECONDS);
554 | 
555 |         retrofit = new Retrofit.Builder()
556 |                 .client(builder.build())
557 |                 .addConverterFactory(GsonConverterFactory.create())
558 |                 .addCallAdapterFactory(RxJavaCallAdapterFactory.create())
559 |                 .baseUrl(DouBanMovieService.BASE_URL)
560 |                 .build();
561 |         movieService = retrofit.create(DouBanMovieService.class);
562 |     }
563 | 
564 |     public void getMovies(Subscriber<Movie> subscriber, int start, int count) {
565 |         movieService.getMovies(start, count)
566 |                 .map(new Func1<Response<List<Movie>>, List<Movie>>() {
567 |                     @Override
568 |                     public List<Movie> call(Response<List<Movie>> listResponse) {
569 |                         return listResponse.getSubjects();
570 |                     }
571 |                 })
572 |                 .flatMap(new Func1<List<Movie>, Observable<Movie>>() {
573 |                     @Override
574 |                     public Observable<Movie> call(List<Movie> movies) {
575 |                         return Observable.from(movies);
576 |                     }
577 |                 })
578 |                 .subscribeOn(Schedulers.io())
579 |                 .observeOn(AndroidSchedulers.mainThread())
580 |                 .subscribe(subscriber);
581 |     }
582 | }
583 | ```
