How to convert Observable<byte[]> to Observable<String>?

Question

I'm reading stdout of an Process using process.getInputStream() . I wan to create an observable that will spew out Strings.

With StringObservable.from(process.getInputStream()) I'm getting Observable<byte[]> . How to translate it in-flight into partial Strings ?

I have found https://github.com/ReactiveX/RxJava/wiki/String-Observables#decode but have no idea how to use it. Text is encoded in UTF-8.

Answer 1

您可以使用public static Observable<String> decode(Observable<byte[]> src, String charsetName) ，例如StringStringObservable.decode(StringObservable.from(process.getInputStream()), "UTF-8")
