Rxjava的基本使用

gradle配置:

    compile 'io.reactivex:rxjava:1.0.9'

观察者:

    Observer<String> observer = new Observer<String>() {
        @Override
        public void onNext(String s) {
            Log.d(tag, s);
        }

        @Override
        public void onCompleted() {
            Log.d(tag, "Completed!");
        }

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

被观察者:

 Observable observable = Observable.create(new Observable.OnSubscribe<String>() {
                    @Override
                    public void call(Subscriber<? super String> subscriber) {
                        subscriber.onNext("Hello");
                        subscriber.onNext("Hi");
                        subscriber.onNext("Aloha");
                        subscriber.onCompleted();
                    }
                });
