위 링크의 gif 파일 처럼 textview가 한 글자씩 도미노처럼 끊어지는 느낌이 아니라 부드럽게 이어져서 나오게 하고 싶은데 방법이 있을까요??

현재 제 코드 입니다

MainActivity.kt

class MainActivity : AppCompatActivity() {
    var text = "946327"
    var hand: Handler? = null
    var runnner: Runnable? = null
    var lenght = text.length
    var index = 0
    public override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        button.setOnClickListener {
            textView.text = (text.toInt()+1).toString()
        }

        hand = Handler()
        val rand = Random()
        runnner = Runnable {
            if (index < lenght) {
                val flowString: String = text.substring(0, ++index)
                Log.d("DEBUG:", flowString)
                textView.text = flowString
                textView.offsetLeftAndRight(3)
                hand!!.postDelayed(runnner!!, 500)
            }
        }
        hand!!.post(runnner!!)
    }
}
