What are this, it, activity in kotlin android exactly?

I am new to android and following the official Android guide. Sometimes I can't understand some keywords in the example codes, like it, this, and activity.

Suppose I have to call a dialog like this:

SampleDialog().show([email protected], null)

What does this@Activity mean?

this is like a this keyword from Java which is a reference to the current object. So, this@MainActivity in Kotlin is equivalent to MainActivity.this in Java. Can read more at this and this.

it is an implicit name of a single parameter in lambda function.

activity is like getActivity() when calling from a fragment. It returns the FragmentActivity this calling fragment is currently associated with.
