How to finish an activity from RecyclerView adapter class using Kotlin

Question

I am new to Kotlin programming language and I want to finish my RecyclerView activity from adapter class. How do I do it? It used to be quite easy in java but I just switched to Kotlin and I am facing this problem.

Answer 1

you can use finish() method ,

(context as YourActivity).finish()

this method will help you to finish the respective activity.

Answer 2

If you use ((Activity)context).finish(); in java than in kotlin you can use (context as Activity).finish()

Try it.

Answer 3

Create this method in the activity:

fun finishMe() { finish() }

In your adapter declare this:

private val activity : MainActivity = context as MainActivity

replace MainActivity with the activity's name and context is the activity's Context passed to the adapter as a parameter (I believe it exists).
Now you can finish the activity anywhere in the adapter by:

activity.finishMe()
