Kotlin：如何从 function 访问 LayoutInflater？

Question

I've a fragment with a recyclerview , i need to fill the RecyclerView from a function, but i don't know how to access to the recyclerView from the function, this is my code:

class ValcuotaDataFragment : Fragment() {
override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle?): View? {
    val root = inflater.inflate(R.layout.fragment_valcuota_data, container, false)

    return root
}
@Subscribe
fun listenItemChange(spinnerData: SpinnerData){   }

i need to do this:

        val rcView= root.findViewById(R.id.rcViewName) as RecyclerView

from the function listenItemChange

Answer 1

Whatever you return from onCreateView() can be later retrieved with getView() . So you're looking for something like view?.findViewById(...) .

Be cautious with fragment lifecycle so you're only trying to use getView() between onCreateView() and onDestroyView() . (It will return null otherwise.)
