How to place an icon just after the last character of a multiline textview

I would like to locate a view just after the last word of a (potentially) multi-line TextView.

For example, the TextView might be two lines, with the second line being about half as long as the TextView's width. How do I locate a View just after the last word.

I also want to attach a click listener on that Icon. I am using data binding.
I tried spannabale strings.

I achieved this functionality.

Have a look

@BindingAdapter("yourTAG")
fun setText(textView: TextView, text: SpannableString?) {
    textView.movementMethod = LinkMovementMethod.getInstance()
    if (!text.isNullOrBlank()) {
        textView.text = text
    }

Then in your viewModel create this function

private fun getSpannable(text:CharSequence): SpannableString{
        val icon: Drawable = resourcesService.getDrawable(R.drawable.your_icon)

        val spannableString = SpannableString(text)
        val position = spannableString.length-1
        icon.setBounds(0, 0, icon.intrinsicWidth, icon.intrinsicHeight)
        val imageSpan = ImageSpan(icon, ImageSpan.ALIGN_BASELINE)

        spannableString.setSpan(imageSpan, position, position +1, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE)
        val clickableSpan = object : ClickableSpan() {
            override fun onClick(widget: View) {
                //TODO
            }
        }
        spannableString.setSpan(clickableSpan, position, position + 1, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE)
        return spannableString
    }

var myField = getSpannable("Thank you Stackoverflow")

In your view

app:yourTAG="@{vm.myField}"

}
