You can also help with its display with the button.

You can play with textview by simply declaring an instance of it in your activity file.

Try this -

    private lateinit var textView:TextView

    override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_main)

    textView = findViewById(R.id.text2)
    var a=(labelProbArray[0][0])
    textView.text= a

    }
