Я думаю, что вам нужно иметь возможность редактировать два поля, а затем, когда вы нажимаете кнопку, вы должны иметь возможность редактировать каждое поле (текстовые поля) и после нажатия кнопки вы хотите распечатать что вы вводите в поля, хорошо, для этого сначала удалите строку:

from kivymd.uix.dialog import MDInputDialog, MDDialog

Потому что это вызовет ошибку. Я изменил это на: from kivymd.uix.dialog import MDDialog

Теперь я понимаю, что вы делаете, как поете на экране, хорошо сделайте следующее:

    from kivy.lang import Builder
from kivy.properties import ObjectProperty
from kivy.uix.scrollview import ScrollView
from kivy.uix.boxlayout import BoxLayout
from kivymd.app import MDApp
from kivymd.uix.list import OneLineListItem
from kivymd.uix.card import MDCardSwipe
from kivy.properties import StringProperty
from kivymd.uix.dialog import MDDialog
notification=1 #1 is yes, 0 is NO
text_scrolls = ["привет, и чё ?","псс, лайк поставь!","https://www.facebook.com/josue.carranza.56884761","https://www.facebook.com/josue.carranza.56884761","https://www.facebook.com/josue.carranza.56884761","https://www.facebook.com/josue.carranza.56884761","https://www.facebook.com/josue.carranza.56884761","https://www.facebook.com/josue.carranza.56884761","https://www.facebook.com/josue.carranza.56884761","https://www.facebook.com/josue.carranza.56884761","https://www.facebook.com/josue.carranza.56884761","https://www.facebook.com/josue.carranza.56884761","https://www.facebook.com/josue.carranza.56884761","https://www.facebook.com/josue.carranza.56884761","https://www.facebook.com/josue.carranza.56884761","https://www.facebook.com/josue.carranza.56884761","https://www.facebook.com/josue.carranza.56884761","https://www.facebook.com/josue.carranza.56884761","https://www.facebook.com/josue.carranza.56884761","https://www.facebook.com/josue.carranza.56884761","https://www.facebook.com/josue.carranza.56884761","https://www.facebook.com/josue.carranza.56884761","https://www.facebook.com/josue.carranza.56884761","https://www.facebook.com/josue.carranza.56884761","https://www.facebook.com/josue.carranza.56884761","https://www.facebook.com/josue.carranza.56884761","https://www.facebook.com/josue.carranza.56884761","https://www.facebook.com/josue.carranza.56884761","https://www.facebook.com/josue.carranza.56884761","https://www.facebook.com/josue.carranza.56884761","https://www.facebook.com/josue.carranza.56884761","https://www.facebook.com/josue.carranza.56884761","https://www.facebook.com/josue.carranza.56884761","https://www.facebook.com/josue.carranza.56884761","https://www.facebook.com/josue.carranza.56884761"]

Используя этот код, вы можете добавлять еще один элемент каждый раз, когда нажимаете его, Кстати, если вы хотите узнать больше, вы можете отправить мне сообщения в мой мессенджер facebook https://www.facebook.com/josue.carranza.56884761
