Android set one TextView's textsize equal to another's

So I have a textview who's size is being set based on android's autoSizeTextType="uniform". I want to copy that size to two other text views.

Here is what I have tried:

    val firstButton = activity?.findViewById<TextView>(R.id.b1)
    val secondButton = activity?.findViewById<TextView>(R.id.b2)
    val thirdButton = activity?.findViewById<TextView>(R.id.b3)

    if (firstButton != null) {
        secondButton?.textSize = firstButton.textSize
        thirdButton?.textSize = firstButton.textSize
    }

This, however, results in the text size of 2 and 3 being about 4x as large as the first. Anyone have any ideas as to what I am doing wrong? I'm guessing it is getting some sort of dpi scaled size, but I'm not sure how to get the correct size.

TextView.getTextSize() returns size in pixels, but setTextSize() interpret parameter as scaled pixels (sp). There's setTextSize() overload which accept text size and unit. In your case unit should be TypedValue.COMPLEX_UNIT_PX.

secondButton?.setTextSize(TypedValue.COMPLEX_UNIT_PX, firstButton.textSize)
