I'm inside an anonymous inner class and wanting to reference the instance of the outside class. In Java it can be referenced using .this preceded by the class name to resolve ambiguity. Like: MainActivity.this. How can I achieve the same in Kotlin? Because the compiler is complaining 'expression 'this' cannot be a selector(occur after a dot)' when I do that. Thanks!

How do I make a variable in one class that can be accessed by another class in Kotlin? You need to reference an instance of the other class and use . dot notation to access its properties. someInstanceOfA.
In certain computer programming languages, the Elvis operator ?: is a binary operator that returns its first operand if that operand is true , and otherwise evaluates and returns its second operand.
In Kotlin, we cannot create an instance of an abstract class. Abstract classes can only be implemented by another class which should be abstract in nature. In order to use an abstract class, we need to create another class and inherit the abstract class.
You can use this@MainActivity to reference the outer class instance.
Tip: I couldn't remember the syntax either, so I just wrote a simple example in Java and asked IntelliJ to convert the class to Kotlin to find the answer.
