For kotlin lovers.

    fun numberPickerCustom() {
        val d = AlertDialog.Builder(context)
        val inflater = this.layoutInflater
        val dialogView = inflater.inflate(R.layout.number_picker_dialog, null)
        d.setTitle("Title")
        d.setMessage("Message")
        d.setView(dialogView)
        val numberPicker = dialogView.findViewById(R.id.dialog_number_picker)
        numberPicker.maxValue = 15
        numberPicker.minValue = 1
        numberPicker.wrapSelectorWheel = false
        numberPicker.setOnValueChangedListener { numberPicker, i, i1 -> println("onValueChange: ") }
        d.setPositiveButton("Done") { dialogInterface, i ->
            println("onClick: " + numberPicker.value)

        }
        d.setNegativeButton("Cancel") { dialogInterface, i -> }
        val alertDialog = d.create()
        alertDialog.show()
    }

and number_picker_dialog.xml
