if you extend Dialog Fragment, put this:

override fun onStart() {
        super.onStart()
        if (dialog != null) {
            dialog!!.getWindow()!!.setLayout(Constraints.LayoutParams.MATCH_PARENT, Constraints.LayoutParams.WRAP_CONTENT) // full width dialog
            val back = ColorDrawable(Color.TRANSPARENT)
            val margin = 16
            val inset = InsetDrawable(back, margin)
            dialog!!.window!!.setBackgroundDrawable(inset)
        }
    }

layoutparams is depend on your dialog parent view
