Howtogetindex/positionoflistinonnextfromObservable.fromIterableRxjava?

I'm trying to loop a list but i'm not getting the index of current item.

Observable.fromIterable(yourList).observeOn(Schedulers.io())
            .observeOn(Schedulers.io()).subscribe(
                { item -> {        }},
                {_ ->{}},
                {->{}}

Is there any way to get index just like

yourList.forEachIndexed{ index, item -> }

I already know that

class Indexed {
int index;
String element;

Indexed(int index, String element) {
    this.index = index;
    this.element = element;
    }
}

this can be used as a solution. But i don't like this kind of approach. I want to know whether Rxjava itself has something for it.

您可以这样使用Iterable.withIndex()：

Observable.fromIterable(yourList.withIndex())
    .observeOn(Schedulers.io())
    .subscribe(
        { (index, item) -> {} },
        { _ -> {} },
        { -> {} }
    )
