OK sorry me again, with some not great code from a course (they are slowly sorting out code to show problems and how to make it better).

override fun getView(position: Int, convertView: View?, parent: ViewGroup): View {
    Log.d(TAG, "getView called pos $position")

    // if convertView is null inflate it otherwise use it
    val view =
        if (convertView == null) {
            Log.d(TAG,"getView called with null convertView")
            inflater.inflate(resource, parent, false)
        } else {
            Log.d(TAG,"getView privided a convertView")
            convertView
        }

    val tvName: TextView = view.findViewById(R.id.tvName)
    val tvArtist: TextView = view.findViewById(R.id.tvArtist)
    val tvSummary: TextView = view.findViewById(R.id.tvSummary)

    val currentApp = applications[position] // position from constructor

    tvName.text = currentApp.name
    tvArtist.text = currentApp.artist
    tvSummary.text = currentApp.summary

    return view
}

Its the 'val view =' bit I have a question about. I get what it is doing, i.e. only running the inflator if needed. What I don't get is why when the method is run again convertView is set. i.e. when is convertView set to view?

ConvertView is passed in as an argument. Whoever is responsible for calling getView is probably reusing the view returned from the previous call

OK, thanks, that makes sense.
