toMap for Arraymap

[kagile]

Is there any way to create ArrayMap instead of HashMap using toMap() in RxJava or RxAndroid?

[JakeWharton]

This is a question for RxJava, not RxAndroid. The answer will be that you need to implement it yourself though, because there's no map factory abstraction in RxJava.

I remember that I used collect() operator for this, something like

observable.collect(() -> new ArrayMap<K,V>(), (map, v) -> map.put(toKey(v), toValue(v))

(you decide what toKey(), toValue() do)

@dimsuz thanks. collect() works fine.
