RxJava2.x-window语法

一、window语法

    public Observable getRxJavaDistinctData() {
        return Observable.just(1, 2, 2, 1, 1, 2, 3, 4, 5, 2);
    }
 public void rxJavaWindowExample() {
        Disposable disposable = model.getRxJavaDistinctData()
                .window(3)
                .subscribeOn(Schedulers.io())
                .unsubscribeOn(Schedulers.io())
                .observeOn(AndroidSchedulers.mainThread())
                .subscribe(new Consumer>() {
                    @Override
                    public void accept(Observable longObservable) throws Exception {
                        LogUtils.error(TAG, "rxJavaReduceExample--:" + Thread.currentThread().getName() + "-consumer1-:" );
                        Disposable disposable1 = longObservable.subscribeOn(Schedulers.io())
                                .unsubscribeOn(Schedulers.io())
                                .observeOn(AndroidSchedulers.mainThread())
                                .subscribe(new Consumer() {
                                    @Override
                                    public void accept(Integer integer) throws Exception {
                                        LogUtils.error(TAG, "rxJavaReduceExample--:" + Thread.currentThread().getName() + "-consumer2-:" + integer);
                                    }
                                });
                        compositeDisposable.add(disposable1);
                    }
                });
        compositeDisposable.add(disposable);
    }

二、window方法2

 public void rxJavaWindowExample() {
        Disposable disposable = model.getRxJavaDistinctData()
                .window(3,2)
                .subscribeOn(Schedulers.io())
                .unsubscribeOn(Schedulers.io())
                .observeOn(AndroidSchedulers.mainThread())
                .subscribe(new Consumer>() {
                    @Override
                    public void accept(Observable longObservable) throws Exception {
                        LogUtils.error(TAG, "rxJavaReduceExample--:" + Thread.currentThread().getName() + "-consumer1-:" );
                        Disposable disposable1 = longObservable.subscribeOn(Schedulers.io())
                                .unsubscribeOn(Schedulers.io())
                                .observeOn(AndroidSchedulers.mainThread())
                                .subscribe(new Consumer() {
                                    @Override
                                    public void accept(Integer integer) throws Exception {
                                        LogUtils.error(TAG, "rxJavaReduceExample--:" + Thread.currentThread().getName() + "-consumer2-:" + integer);
                                    }
                                });
                        compositeDisposable.add(disposable1);
                    }
                });
        compositeDisposable.add(disposable);
    }

总结

1、window(long count) 被分割成的每个window最大数据值
2、window(long count, long skip) count 每个window最大数据值，skip步长
3、window与buffer区别：window是把数据分割成了Observable，buffer是把数据分割成List
