如何从Kotlin的内部类访问外部类的成员？

Question

How to access the member of outer class from member function of inner class in kotlin. Consider the following code.

class A{
    var name: String

    class B{
        fun show(){
            print(name)          //<----- here ide shows error. name is not accessible
        }
    }
}

I am writing this code in android studio. It is working when written in java but not when we write code in kotlin.

Answer 1

You should mark class B as inner :

class A{
  var name: String

  inner class B{
    fun show(){
      print(name)
    }
  }
}

Answer 2

Use like this

class A{
lateinit var name: String

inner class B{
    fun show(){
        print(name)
    }
}
}
