Android使用rxjava

导入包

    implementation "io.reactivex.rxjava2:rxjava:2.2.10"
    implementation "io.reactivex.rxjava2:rxandroid:2.0.2"

使用

private void executeAsyncTask() {
        //Observable#create方法创建一个异步任务
        Observable.create(new ObservableOnSubscribe<Integer>() {
                    @Override
                    public void subscribe(@NonNull ObservableEmitter<Integer> e) throws Exception {
                       e.onComplete();
                    }
                })
                .subscribe(new Observer<Integer>() {
                    @Override
                    public void onSubscribe(@NonNull Disposable d) {
                    }

                    @Override
                    public void onNext(@NonNull Integer integer) {
                    }

                    @Override
                    public void onError(@NonNull Throwable e) {
                    }

                    @Override
                    public void onComplete() {
                    }
                });

    }
