How to set the margins in TextInputEditText programmatically in Kotlin

How do I set the margins of my TextInputEditText programmatically in Kotlin in a AlertDialogBuilder?

val input = TextInputEditText(context!!)
            input.gravity = Gravity.CENTER
            CommonHelper.capitalizeTextbox(input)
            input.inputType =
                InputType.TYPE_CLASS_TEXT
            input.setSingleLine()
            input.gravity = Gravity.CENTER

            val lp: LinearLayout.LayoutParams = LinearLayout.LayoutParams(
                LinearLayout.LayoutParams.MATCH_PARENT,
                LinearLayout.LayoutParams.WRAP_CONTENT
            )

            input.layoutParams = lp
            setMargins(input, 50,10,50,10)
            alertDialog.setView(input)
            alertDialog.setIcon(R.drawable.ic_plate)


private fun setMargins(view: View, left: Int, top: Int, right: Int, bottom: Int) {
    if (view.layoutParams is MarginLayoutParams) {
        val p = view.layoutParams as MarginLayoutParams
        p.setMargins(left, top, right, bottom)
        view.layoutParams = p
        view.invalidate()
    }
}

I tried lp.setMargins(50, 10, 50, 10) but it doesn't work too

You did the correct approach by setting the margin on the layoutParams. The miss here is that you have to apply the layout params back to the view and call invalidate().

So your setMargins function code should look like below:

private fun setMargins(view: View, left: Int, top: Int, right: Int, bottom: Int) {
    if (view.layoutParams is ViewGroup.LayoutParams) {
        val p = view.layoutParams
        p.setMargins(left, top, right, bottom)
        // Set the layout params back to the view
        view.layoutParams = p
        // Call invalidate to redraw the view
        view.invalidate()
    }
}

EDIT: The if check for MarginLayoutParams instance check won't be satisfied because your params are of the LinearLayoutParams type.
