rxjava 三：subscribe() 的方法重载

subscribe() 的方法重载

1、subscribe()

 Observable.create(new ObservableOnSubscribe() {   //创建事件发射器
            @Override
            public void subscribe(ObservableEmitter emitter) throws Exception {
                emitter.onNext(1);
                emitter.onNext(2);
                emitter.onNext(3);
                emitter.onComplete();
                emitter.onNext(4);
                emitter.onNext(5);
                Log.i("zqq","发送事件");
            }
        })
                .subscribe();

结果：

表示，只管发送事件，无人处理

2、subscribe(Consumer onNext)

 Observable.create(new ObservableOnSubscribe() {   //创建事件发射器
            @Override
            public void subscribe(ObservableEmitter emitter) throws Exception {
                emitter.onNext(1);
                emitter.onNext(2);
                emitter.onNext(3);
                emitter.onComplete();
                emitter.onNext(4);
                emitter.onNext(5);
                Log.i("zqq","发送事件");
            }
        })
//                .subscribe();
        .subscribe(new Consumer() {
            @Override
            public void accept(Integer integer) throws Exception {
                Log.i("zqq","accept>>"+integer);
            }
        });

结果：

表示，只处理了onnext()事件

3、subscribe(Consumer onNext, Consumer onError)

Observable.create(new ObservableOnSubscribe() {   //创建事件发射器
            @Override
            public void subscribe(ObservableEmitter emitter) throws Exception {
                emitter.onNext(1);
                emitter.onNext(2);
                emitter.onNext(3);
                emitter.onError(new NullPointerException());
                emitter.onNext(4);
                emitter.onNext(5);
                Log.i("zqq","发送事件");
            }
        })
        .subscribe(new Consumer() {
                       @Override
                       public void accept(Integer integer) throws Exception {
                           Log.i("zqq","accept1>>"+integer);
                       }
                   }, new Consumer() {
                       @Override
                       public void accept(Throwable throwable) throws Exception {
                           Log.i("zqq","accept2>>"+throwable);
                       }
                   }
        );

运行结果：

第一个Consumer 接收onNext(）事件，第二个接收onError()事件

其他重载方法类似都对应了Observer的对应方法
