Well, the doco says to do it: https://developer.android.com/training/basics/firstapp/starting-activity.html I haven't seen documentation this useless since shortly before I gave up using C++ for Windows programming and switched to Java. Anyway, using Kotlin Android Extensions I've got past that bit and am onto the next thing which doesn't work how the documentation says it does.
