最近听说Retrofit2+RxAndroid2很火，所以简单的了解了下Retrofit2+RxAndroid2。

1：添加依赖

compile 'io.reactivex.rxjava2:rxjava:2.0.1'
compile 'io.reactivex.rxjava2:rxandroid:2.0.1'
//compile 'com.squareup.retrofit2:adapter-rxjava:2.1.0'//retrofit现在只支持到rxjava1.XX
compile 'com.squareup.retrofit2:retrofit:2.1.0'
compile 'com.jakewharton.retrofit:retrofit2-rxjava2-adapter:1.0.0'// 大神写的这个库可以支持到rxjava2.X
compile 'com.squareup.retrofit2:converter-gson:2.1.0'
compile 'com.squareup.okhttp3:okhttp:3.4.1'
compile 'com.squareup.okhttp3:logging-interceptor:3.4.1'

2：创建Retroft

public class RetrofitManager {    private static ParentApi mParentApi = null;    private static String mIp = Constant.ip;    private static int mHost = Constant.port;    private RetrofitManager(){}    private static synchronized Retrofit getRetrofit(){        // Log信息拦截器        HttpLoggingInterceptor httpLoggingInterceptor = new HttpLoggingInterceptor();        httpLoggingInterceptor.setLevel(HttpLoggingInterceptor.Level.BODY);        //log打印级别，决定了log显示的详细程度        OkHttpClient.Builder builder = new OkHttpClient.Builder();        builder.addInterceptor(httpLoggingInterceptor);        //超时时间设置，默认60秒        builder.readTimeout(60000, TimeUnit.MILLISECONDS);      //全局的读取超时时间        builder.writeTimeout(60000, TimeUnit.MILLISECONDS);     //全局的写入超时时间        builder.connectTimeout(60000, TimeUnit.MILLISECONDS);   //全局的连接超时时间        //自动管理cookie（或者叫session的保持        builder.cookieJar(new CookieJar() {            private final HashMap<HttpUrl, List<Cookie>> cookieStore = new HashMap<>();            @Override            public void saveFromResponse(HttpUrl url, List<Cookie> cookies) {                cookieStore.put(url, cookies);            }            @Override            public List<Cookie> loadForRequest(HttpUrl url) {                List<Cookie> cookies = cookieStore.get(url);                return cookies != null ? cookies : new ArrayList<Cookie>();            }        });        OkHttpClient client = builder.build();        return new Retrofit.Builder()                .client(client)                .baseUrl(String.format(Api.baseUrl, Constant.ip, Constant.port))                .addCallAdapterFactory(RxJava2CallAdapterFactory.create())                .addConverterFactory(GsonConverterFactory.create())                .build();    }    public static synchronized ParentApi getApi(){        if(null == mParentApi){            mParentApi = getRetrofit().create(ParentApi.class);            return mParentApi;

//这里是根据自己的逻辑写的，我用到的是IP跟port会动态改变的        } else if(!mIp.equals(Constant.ip) || mHost != Constant.port){            mIp = Constant.ip;            mHost = Constant.port;            mParentApi = getRetrofit().create(ParentApi.class);            return mParentApi;        }        return mParentApi;    }}

3：创建注解

public interface ParentApi {    /*************************************************SSN**************************************************************/    @POST("your interface")    Observable<SchoolBean> getAllRecorderStates(@Body Map<String,String> map);}

4：RxAndroid使用

Map<String,String> map = new HashMap<>();map.put("key", "value");map.put("key2", "value2");setLoadingState(LOAD_STATE.STATE_LOADING);Observable<SchoolBean> observable = RetrofitManager.getApi().getAllRecorderStates(map);observable.subscribeOn(Schedulers.newThread())        .observeOn(AndroidSchedulers.mainThread())        .subscribe(new Observer<SchoolBean>() {            @Override            public void onSubscribe(Disposable d) {                //取消订阅            }            @Override            public void onNext(SchoolBean schoolBean) {                //可实现自己的逻辑            }            @Override            public void onError(Throwable e) {                setLoadingState(LOAD_STATE.STATE_EMPTY);            }            @Override            public void onComplete() {            }        });
