How to reference "this" within anonymous listeners when using short notation?

Question

In Kotlin, is there a way to reference the listener instance when using this short notation for anonymous classes? In this case this refers to outer context (e.g. the Activity instance) where view is defined:

view.setOnClickListener {
    val self: View.OnClickListener = this // Not compiling, "this" references outer context
}

When using the longer notation where you explicitly state the interface to be implemented and where you explicitly override the callback method, the listener can be referenced through this:

view.setOnClickListener(object: View.OnClickListener {
    override fun onClick(v: View) {
        val self: View.OnClickListener = this // Ok
    }
})

Answer 1

You can get that resolved by adding an @ActivityName in front of 'this' reference For example if your Activity name was MainActivity the solution would be:

view.setOnClickListener {
    val self: View.OnClickListener = this@MainActivity 
}

Answer 2

The term short notation for anonymous classes is not entirely correct. It's actually a short notation for anonymous functions, i.e. lambdas. Of course under the hood they are compiled to classes but from a programming language point of view, anonymous functions don't have identities and therefore it doesn't make sense to refer to their instances via this.
