Filter list of objects in RxJava

Question

I am trying to filter the list on the basis of it\'s property. For example, Sensors class has a property isActive and I want to get all the objects with isAct

Answer 1

I wanted to delete the values of a list based on Rejex and finally return a Observable list model

fun getList(): Observable> {
    return appDataBase.dao().getAllList().flatMap {
        Observable.fromIterable(it).filter { destination ->
            destination.number.matches(regex = "[+]*[(]{0,1}[0-9]{1,4}[)]{0,1}[-\\s\\./0-9]*\$".toRegex())
        }.toList().toObservable()
    }.subscribeOn(Schedulers.io())
            .observeOn(AndroidSchedulers.mainThread())

}

I hope this helps
