Drawable Programmatically 하게 만들기 (seekbar background)

Android Seekbar progressDrawable 을 xml 상에서 말고 Programmatically하게 kotlin 코드로 만들어보기

//.xml로 만들기 

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <!-- seekbar 배경 -->
    <item android:id="@android:id/background">
