试试这个，我希望这对你有帮助。

//ContactsContract defines an extensible database of contact-related information
    var uri = ContactsContract.Data.CONTENT_URI

    val PROJECTION = arrayOf(
        ContactsContract.Data.CONTACT_ID,
        ContactsContract.Data.DISPLAY_NAME,
        ContactsContract.Data.PHOTO_URI,
        ContactsContract.Data.DATA1
    )

    var cursor =
        contentResolver.query(uri, PROJECTION, ContactsContract.Data.MIMETYPE + " = ?", arrayOf(
            ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE
        ), ContactsContract.Contacts.DISPLAY_NAME + " ASC ", null)

    while (cursor.moveToNext())
    {
        val contactId =
            cursor!!.getString(cursor!!.getColumnIndex(ContactsContract.Data.CONTACT_ID))
        val photo = cursor!!.getString(cursor!!.getColumnIndex(ContactsContract.Data.PHOTO_URI))
        val name = cursor!!.getString(cursor!!.getColumnIndex(ContactsContract.Data.DISPLAY_NAME))
        val phone = cursor!!.getString(cursor!!.getColumnIndex(ContactsContract.Data.DATA1))
    }
