源码分析1

     1、基本的订阅、事件发射、取消订阅

    public static void case2() {
        Observable.create(new ObservableOnSubscribe<Integer>() {
            @Override
            public void subscribe(ObservableEmitter<Integer> emitter) throws Exception {
                Log.d(TAG, "emit 1");
                emitter.onNext(1);
                Log.d(TAG, "emit 2");
                emitter.onNext(2);
                Log.d(TAG, "emit 3");
                emitter.onNext(3);
                Log.d(TAG, "emit onComplete");
                emitter.onComplete();
                Log.d(TAG, "emit 4");
                emitter.onNext(4);
            }
        }).subscribe(new Observer<Integer>() {
            private Disposable mDisposable;
            private int mCount = 0;

            @Override
            public void onSubscribe(Disposable d) {
                Log.d(TAG, "onSubscribe");
                mDisposable = d;
            }

            @Override
            public void onNext(Integer value) {
                Log.d(TAG, "onNext: value = " + value);
                mCount++;
                if (mCount == 2) {
                    Log.d(TAG, "dispose");
                    mDisposable.dispose();
                    Log.d(TAG, "isDisposed : " + mDisposable.isDisposed());
                }
            }

            @Override
            public void one rror(Throwable e) {
                Log.d(TAG, "onError: " + e.toString());
            }

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

     2、线程调度

    public static void case4() {
        Observable.create(new ObservableOnSubscribe<Integer>() {
            @Override
            public void subscribe(ObservableEmitter<Integer> emitter) throws Exception {
                Log.d(TAG, "subscribe: thread = " + Thread.currentThread());
                emitter.onNext(1);
                emitter.onComplete();
            }
        })
                .subscribeOn(Schedulers.io())
                .observeOn(AndroidSchedulers.mainThread())
                .subscribe(new Consumer<Integer>() {
                    @Override
                    public void accept(Integer integer) throws Exception {
                        Log.d(TAG, "accept: thread = " + Thread.currentThread());
                    }
                });
    }
