RxJava

Observable: 被观察者
Observer: 观察者
subscribe: 订阅
observeOn(): 事件回调线程
subscribeOn(): 事件执行线程

第一种创建方式

// 创建被观察者
Observable novel = Observable.create(new ObservableOnSubscribe() {
    @Override
    public void subscribe(ObservableEmitter emitter) throws Exception {
        emitter.onNext("连载1");
        emitter.onNext("连载2");
        emitter.onNext("连载3");
        emitter.onComplete();
    }
});

// 创建观察者
Observer reader = new Observer() {
    @Override
    public void onSubscribe(Disposable d) {
        Log.d("WuMeng","onSubscribe");
    }

    @Override
    public void onNext(String s) {
        Log.d("WuMeng",s);
    }

    @Override
    public void onError(Throwable e) {
        Log.d("WuMeng","onError");
    }

    @Override
    public void onComplete() {
        Log.d("WuMeng","onComplete");
    }
};

novel.subscribe(reader);

第二种创建方式

Observable.create(new ObservableOnSubscribe() {
    @Override
    public void subscribe(ObservableEmitter emitter) throws Exception {

    }
}).observeOn(AndroidSchedulers.mainThread()) // 回调在主线程
        .subscribeOn(Schedulers.io()) // 执行在io线程
        .subscribe(new Observer() {
            @Override
            public void onSubscribe(Disposable d) {

            }

            @Override
            public void onNext(String s) {

            }

            @Override
            public void onError(Throwable e) {

            }

            @Override
            public void onComplete() {

            }
        });
