I set the part of the textView is clickable using SpannableString. But it is very difficult for me to detect a long press my textView.

private fun makeTextLink(textView: TextView, str: String, underlined: Boolean, color: Int?, action: (() -> Unit)? = null) {
    val spannableString = SpannableString(textView.text)
    val textColor = color ?: textView.currentTextColor
    val clickableSpan = object : ClickableSpan() {
        override fun onClick(textView: View) {
            action?.invoke()
        }
        override fun updateDrawState(drawState: TextPaint) {
            super.updateDrawState(drawState)
            drawState.isUnderlineText = underlined
            drawState.color = textColor
        }
    }
    val index = spannableString.indexOf(str)
    spannableString.setSpan(clickableSpan, index, index   str.length, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE)
    textView.text = spannableString
    textView.movementMethod = LinkMovementMethod.getInstance()
    textView.highlightColor = Color.TRANSPARENT
}

TextView textView = findViewById(R.id.text_view);
        String text = "First Click THIS and then THIS ";
  
        SpannableString ss = new SpannableString(text);
          
        // creating clickable span to be implemented as a link
        ClickableSpan clickableSpan1 = new ClickableSpan() {
            public void onClick(View widget) {
                Toast.makeText(MainActivity.this, "First Clickable Text", Toast.LENGTH_SHORT).show();
            }
        };
          
        // creating clickable span to be implemented as a link
        
          
        // setting the part of string to be act as a link
        ss.setSpan(clickableSpan1, 12, 16, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
        
  
        textView.setText(ss);
        textView.setMovementMethod(LinkMovementMethod.getInstance());
