Answer 1

Define your nested class as inner then you will be able to access an outer class member variable.

class OuterClass{

var accessMe ="access me from Inner Class"

    inner class InnerClass{

       //....


        fun accessingOuterClassVariable(){

           accessMe = "Now the variable is accessed"

        }

    }

}

Answer 2

to answer this question for the fast an easy way i would do something like following :

class OuterClass{

private var accessibleInside: CustomObject? = null
inner class InnerClass{

    //....
}

now the CustomObject could be anything from Context to String hope this helps someone.

Answer 3

You should use the inner modifier in your adapter.

This modifier makes the inner class have access to the members of the outer class
