Kotlin: No adapter attached; skipping layout

Question

I have a recycler view and a custom adapter, I have the adapter attached but I get "No adapter attached; skipping layout"

    timetableRecyclerView?.apply {
    layoutManager = LinearLayoutManager(getContext(), RecyclerView.VERTICAL, false)
    // set the custom adapter to the RecyclerView
    adapter = timetableAdapter
    }

And here is my Time table adapter, I call the populate method on a call back on my activity which populates the data

 fun populate(timetable: Timetable) {
        timetableList.add(timetable)
        notifyDataSetChanged()
    }


    override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): ViewHolder {
        val row = LayoutInflater.from(parent.context).inflate(R.layout.timetable_row, parent, false)
        return ViewHolder(row)
    }

    override fun onBindViewHolder(viewHolder: ViewHolder, position: Int) {
        val (type, status, departure, arrival, airline, flight) = timetableList[position]



        viewHolder.airline!!.text = airline.name

        viewHolder.flightNumber!!.setText(flight.number)
        viewHolder.status!!.text = status

        when (status) {
            "active" -> {
                viewHolder.status!!.text = StringUtils.capitalize(status)
                viewHolder.flightDepartureStatus!!.setImageResource(R.drawable.green_dot)
                return
            }
            "landed" -> {
                viewHolder.status!!.text = StringUtils.capitalize(status)
                viewHolder.flightDepartureStatus!!.setImageResource(R.drawable.red_dot)
                return
            }
            else -> {
                viewHolder.status!!.text = StringUtils.capitalize(status)
                viewHolder.flightDepartureStatus!!.setImageResource(R.drawable.red_dot)
                return
            }
        }

    }
       override fun getItemCount(): Int {
        return timetableList.size
    }

From the code you posted it is not clear what `timetableAdapter` is. Post some more code to let us understand how and when it is created. — gpunto, May 14 '19 at 15:07
Where is `timetableAdapter` assigned? It is not in the code you posted — gpunto, May 14 '19 at 17:03
I meant where is `timetableAdapter = ...`? From the pieces of code you posted the flow is not clear. Can you post the activity/fragment where you are using `timetableAdapter`? The one that contains `timetableRecyclerView?.apply` — gpunto, May 15 '19 at 09:03
here timetableAdapter = TimetableAdapter(timetableList, this) — Roger Nkosi, May 15 '19 at 11:20

Did you debug the application? Are `timetableRecyclerView` and `timetableAdapter` not null and adapter contains items? — CoolMind, May 15 '19 at 12:10
Are you sure that `timetableRecyclerView` is not null when you call `apply`? — lelloman, May 15 '19 at 13:24

the Recyclerview was null because I was trying to use Butterknife, I have been doing Kotlin for a week now and it has not been easy.

Stop using ButterKnife and use synthetic view imports https://kotlinlang.org/docs/tutorials/android-plugin.html – Zun May 16 '19 at 09:37
@ZUNJAE, agree. – CoolMind May 16 '19 at 10:42
