Hello,Please can you help me ? I am beginner. I'm not sure how to do it. /Kotlin/ Thanks

CustomAdapter(this, listOf())

might make the error go away. Your question requires more context on what you want the ouput to be and belongs on StackOverflow as it doesn't seem Kotlin specific.

I tried to change it and it does not work 😞

It does not work for me 😞

You're missing a bracket at the end of that line 29.

Move line 33 to line 45.

without a change

You should try to understand the basics of Kotlin and programming in general before doing anything app related.

I was already working on trying to add SearchView 🙂
