Не обновляется TextView и другие View при изменении значения одного из полей

Question

Пишу приложение для управления гексакоптером. Написал для проверки обработчики нажатий кнопок(onClickTakeOff, onClickLanding), чтобы менялся текст и углы поворотов(элементы находятся по id), которые являются полями моего самостоятельно написанного класса HexaView, который наследует класс View. Так вот после нажатия на кнопку обработчик срабатывает и значение полей классов изменяется(проверено), а на экране не обновляется ни текст, ни отклонения стрелок, которые зависят от заданных углов, хотя по идеи должно, в чем может быть проблема? Как обновить экран с новыми значениями полей классов? Вот код:

MainActivity:

package com.example.hexacopterapp

import android.app.Activity
import android.os.Bundle
import android.os.SystemClock
import android.util.Log
import android.view.View
import android.view.Window
import android.view.WindowManager

import androidx.appcompat.app.AppCompatActivity
import com.example.hexacopterapp.view.HexaView

class MainActivity : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN)
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
    }

    fun onClickTakeOff(view : View) {
        val txt = findViewById<TextView>(R.id.textView23)
        txt.text = "sss"
        val HView = findViewById<HexaView>(R.id.hexaView)
        HView.angle_cren = 155f
        HView.angle_tang = 15f
        HView.angle_risk = 30f
        Log.d("MyLog", txt.text.toString())
        Log.d("MyLog", HView.angle_cren.toString())
    }

    fun onClickLanding(view : View) {
        val HView = findViewById<HexaView>(R.id.hexaView)
        HView.angle_cren = -25f
        HView.angle_tang = -15f
        HView.angle_risk = -125f
        Log.d("MyLog", HView.angle_cren.toString())
    }

    override fun onResume() {
        val i = 1
        val HView = findViewById<HexaView>(R.id.hexaView)
        super.onResume()
        //while (true) {
            //for (i in 0..30) {
                //SystemClock.sleep(1000)
                //HView.angle_cren = i.toFloat()
            //}
        //}
    }


}

Припишите в вашем View функцию например:

class HexaView : View {
    private val paint = Paint(Paint.ANTI_ALIAS_FLAG)
    private val paint_text = Paint(Paint.ANTI_ALIAS_FLAG)
    var angle_cren: Float = 15f
    var angle_tang: Float = 10f
    var angle_risk: Float = 225f
    val a = 1
    fun setCrenParams(angle_cren:Float, angle_cren:Float, angle_risk:Float) {
        this.angle_cren = angle_cren
        this.angle_tang= angle_tang
        this.angle_risk= angle_risk
        invalidate();
        requestLayout();
    }
 А потом из MainActivity вызывайте. Все должно обновлять

Не обновляется TextView и другие View при изменении значения одного из полей
