1，現在響應式編程也是越來越多在項目中使用了，剛好上篇我們簡單了介紹了一下Retrofit，那麼我們來開始試著兩個一起用吧，不過不瞭解RxJava的同學可以先去看一看這個文章（挺好的）：http://gank.io/post/560e15be2dca930e00da1083#toc_27

2，接著我們上一個項目的寫，怎麼添加RxJava到我們網路請求架構中呢，首先我們得修改Service的代碼為

public interface MovieService {    @GET("top250")    Observable<MovieEntity> getTopMovie(@Query("start") int start, @Query("count") int count);}

　然後我們Activity中的getMovie（）方法修改為　

package com.qianmo.retrofitdemo;import android.os.Bundle;import android.support.v7.app.AppCompatActivity;import android.view.View;import android.widget.Button;import android.widget.TextView;import android.widget.Toast;import com.qianmo.retrofitdemo.entry.MovieEntity;import com.qianmo.retrofitdemo.http.MovieService;import butterknife.Bind;import butterknife.ButterKnife;import butterknife.OnClick;import retrofit2.Call;import retrofit2.Callback;import retrofit2.Response;import retrofit2.Retrofit;import retrofit2.adapter.rxjava.RxJavaCallAdapterFactory;import retrofit2.converter.gson.GsonConverterFactory;import rx.Subscriber;import rx.android.schedulers.AndroidSchedulers;import rx.schedulers.Schedulers;public class MainActivity extends AppCompatActivity {    @Bind(R.id.tv_show)    TextView tvShow;    @Bind(R.id.btn_request)    Button btnRequest;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        ButterKnife.bind(this);    }    @OnClick({R.id.btn_request})    public void onClick(View view) {        switch (view.getId()) {            case R.id.btn_request:                getMovie();                break;        }    }    //請求網路資料    private void getMovie() {//        //https://api.douban.com/v2/movie/top250?start=0&count=10 目標地址//        String baseUrl = "https://api.douban.com/v2/movie/";////        //建立Retrofit對象//        Retrofit retrofit = new Retrofit.Builder()//                .baseUrl(baseUrl)//                .addConverterFactory(GsonConverterFactory.create())//                .build();////        MovieService movieService = retrofit.create(MovieService.class);//        Call<MovieEntity> call = movieService.getTopMovie(0, 10);//        call.enqueue(new Callback<MovieEntity>() {//            @Override//            public void onResponse(Call<MovieEntity> call, Response<MovieEntity> response) {//                tvShow.setText(response.body().getTitle());//            }////            @Override//            public void onFailure(Call<MovieEntity> call, Throwable t) {//                tvShow.setText(t.getMessage());//            }//        });        String baseUrl = "https://api.douban.com/v2/movie/";        Retrofit retrofit = new Retrofit.Builder()                .baseUrl(baseUrl)                .addConverterFactory(GsonConverterFactory.create())                .addCallAdapterFactory(RxJavaCallAdapterFactory.create())                .build();        MovieService movieService = retrofit.create(MovieService.class);        movieService.getTopMovie(0, 10)                .subscribeOn(Schedulers.io())                .observeOn(AndroidSchedulers.mainThread())                .subscribe(new Subscriber<MovieEntity>() {                    @Override                    public void onCompleted() {                        Toast.makeText(MainActivity.this, "Get Top Movie Completed", Toast.LENGTH_SHORT).show();                    }                    @Override                    public void onError(Throwable e) {                        tvShow.setText(e.getMessage());                    }                    @Override                    public void onNext(MovieEntity movieEntity) {                        tvShow.setText(movieEntity.getTitle());                    }                });    }}

這樣我們就簡單的把RxJava整合過來了
