How can I unlock a cardview(replace the layout file) after it qualifies the condition in an adapter class?

Question

I have a Fragment named Flashcards.kt and it's adapter class named FlashcardEasyAdapter. This is the UI image of my fragment screenUI Image so here as you can only first card "Questions and Pronouns" in the Easy cards is unlocked by default and other cards are locked and I have to unlocked as the condition passes. Below is the code of my Flashcards.kt

}

Below is the code of the data class FlashCardInfo

data class FlashCardInfo(val imageId:Int,
                     var name:String,
                     val translation:String,
                     val topRightValue:Int,
                     val topRightImage:Int)

So my condition does get passed in the adapter class and the the Toast message of "Card Unlocked" also gets displayed but my Cardview doesn't get displayed, it's locked layout doesn't changed to unlocked layout an i am not able to able access the "Pointers" flashcard here.

I tried to manually the position of the string by connecting it with imagelist position but still layout of the cardview is not unlocking (For example "Pointers") in this case. I want card "Pointers" to get unlocked so i can access the content inside it
