How to get properties from the list of objects and put to the String

Question

I am trying to get the properties from the list of objects and put them to the textView. I know how to get one property by the index with get(), but is it possible to retrieve all the text properties from the list and put them to the string in one line?

val listObserver = Observer<List<Word>?> { newName ->
            // Update the UI, in this case, a TextView.
            testObject.text = viewModel.listForQuiz.value?.get(5)?.text.ToString()
    }

here is the object class

data class Word(val lang:String,
                val text:String,
                val translations:List<Translation>){

Instead of get(), use joinToString(", ", Word::text). The first argument is whatever String you want to put between entries. — Tenfour04

You can use joinToString()

        val listObserver = Observer<List<Word>?> { newName ->
                // Update the UI, in this case, a TextView.
                testObject.text = viewModel.listForQuiz.value?.joinToString { it.name }
        }
