In constructor(ctx: Context) : super(ctx), what's happening is that when you call MyView(someContext) in order to instantiate the class, the constructor also needs to first call it's superclass's constructor (View) - that's what the : super(ctx) is doing. It sets up the superclass before it sets up itself.
