PARAMETER FOR SORT ORDER

Question

I’m taking a course and would like to order the return list by name. I tried inserting as DISPLAY_NAME parameter but does not return. Could help me know how to identify and what parameter to return in that order?

in that passage >>

val cursor = contentResolver.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
        null,
        null,
        null,
        null)

follows Cód >>

val REQUEST_CONTACT = 1
val LINEAR_LAYOUT_VERTICAL = 1

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_contact)

    if (ActivityCompat.checkSelfPermission(
            this,android.Manifest.permission.READ_CONTACTS)
        != PackageManager.PERMISSION_GRANTED){
        ActivityCompat.requestPermissions(this,
        arrayOf(Manifest.permission.READ_CONTACTS), REQUEST_CONTACT)
    }else{
        setContacts()
    }
}

@SuppressLint("MissingSuperCall")
override fun onRequestPermissionsResult(
    requestCode: Int,
    permissions: Array<out String>,
    grantResults: IntArray
) {
    if (requestCode == REQUEST_CONTACT) setContacts()
}

private fun setContacts() {
    val contactList: ArrayList<Contact> = ArrayList()


    val cursor = contentResolver.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
            null,
            null,
            null,
            null)


    if (cursor != null){
        while (cursor.moveToNext()){
            contactList.add(Contact(
                    cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME)),
                    cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER))

            ))
        }
        cursor.close()
}
    val adapter = ContactsAdapter(contactList)
    val contactRecyclerView = findViewById<RecyclerView>(R.id.contacts_rv)

    contactRecyclerView.layoutManager= LinearLayoutManager(
            this,
            LINEAR_LAYOUT_VERTICAL,
            false
            )

    contactRecyclerView.adapter = adapter
}
