Emit each item from Flowable Room ORM

I have a list of items in the Room ORM which I would like to display in a Recycler view. The data is being added from the network to the db. The problem is I am getting every time the whole list emited from the Flowable and not each item. I have tried with .distinctUntilChanged with no difference.

@Query("SELECT * FROM items")
Flowable<List<Item>> getItems();

I have tried also to return only a single item which loads only the first one that is the db.

You can use flatMap and Flowable.fromIterable() to map to Flowable which will emit all items one by one

getItems()
    .flatMap(Flowable::fromIterable)
    .subscribe(item -> {

    });

That's it. Short and clean code, without casting toArray
