The TextView.setText() method isn't working For a Textview In my splash screen-CodePudding

I cant't set a text view in my splash screen, Using the below code

override fun onCreate(savedInstanceState: Bundle?) {
setContentView(R.layout.activity_main);
            val textView = findViewById<TextView>(R.id.rand)
            val thoughts = arrayOf("Trading Made Easy!","Where Smart People Trade","For Smart Traders Like You!")
            fun getRandomQuote(): String {
                val randomValue = kotlin.random.Random.nextInt(thoughts.size-1)
                return thoughts[randomValue]
            }
            var thought = getRandomQuote().toString()
    
            textView.setText(thought)
    }

the splash screen just shows the default text in the .xml file ,

 <TextView
                android:id="@ id/rand"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="The Future Of Trading"
                android:layout_below="@ id/app_logo"
                android:layout_marginTop="0dp"
                android:textSize="18sp"
                android:textColor="@color/colorBlack"
                android:textStyle="bold"
                android:layout_centerHorizontal="true" />

In your code, you havent called super.oncreate.

It might throw SuperNotCalledException.

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

In your code remove this part :

thought = getRandomQuote().toString()

       textView.setText(thought)

And write this in place of it

textView.text = getRandomQuote()
