我正在尝试使用 KivyMD 和 Python 制作一个基本的 UI（我是初学者），但我遇到了一些出价问题。如果你们中有人能帮助我，我将非常感激。这是我的 IDE 返回给我的错误：

文件“C:\Users\kaua.silva\Desktop\app_ig\app.kv”，第 67 行，在 on_release 中： root.get_texts() ^^^^^^^^^^^^^^^ 文件“kivy\weakproxy .pyx”，第 32 行，在 kivy.weakproxy.WeakProxy 中。getattr AttributeError：“FloatLayout”对象没有属性“get_texts”

main.py 文件：

from kivymd.tools.hotreload.app import MDApp
from kivy.lang import Builder
from kivy.core.window import Window

class App(MDApp):
    def get_texts(self):
        user_text_field = self.root.ids.username
        user_text_field = user_text_field.text

        password_text_field = self.root.ids.passoword
        password_text_field = password_text_field.text

        quantity_text_field = self.root.ids.quantity
        quantity_text_field = quantity_text_field.text

        return user_text_field, password_text_field, quantity_text_field

    KV_FILES = ["app.kv"]
    DEBUG = True
    def build_app(self):
        Window.size = (320, 370)
        Window.resizable = 0
        return Builder.load_file("app.kv")

App().run()

应用程序.kv 文件：

        size_hint: .5, .13
        pos_hint: {"center_x": .5, "center_y": .155}
        font_size: "16sp"
        on_release: root.get_texts()

我想将函数 get_texts （它只是一个符号函数，我将替换为另一个函数）与 MDRaishedButton 绑定，但 vscode 无法识别该函数。提前致谢！
