How do I turn the text that is inputed by a user into a kivyMD text box to a variable in python file?

Im relatively new to Kivy/KivyMD. I cant figure out how to take the values from the username and password text fields and turn them into variable in my python file when the sign up button is pressed.
Currently when the Signup button is clicked it just prints "clicked".
Any help would be greatly appreciated!
Below is my python file:
from kivymd.app import MDApp
from kivymd.uix.relativelayout import MDRelativeLayout
from kivy.lang import Builder
from kivy.properties import StringProperty, ObjectProperty
from kivy.uix.screenmanager import ScreenManager, Screen, SwapTransition
Builder.load_file('ALevelNEA.kv')
##Below are the classes for my different screens
class SignupScreen(Screen):
pass
class MenuScreen(Screen):
pass
class SigninScreen(Screen):
pass
## Below are the classes for my custom buttons, widgets and text fields
class PasswordField(MDRelativeLayout):
text = StringProperty()
hint_text = StringProperty()
pass
class EmailField(MDRelativeLayout):
text = StringProperty()
hint_text = StringProperty()
#email_field = ObjectProperty(None)
##Below is the code for my main app
class MainApp(MDApp):
def build(self):
sm = ScreenManager(transition= SwapTransition())
sm.add_widget(MenuScreen(name='menu'))
sm.add_widget(SigninScreen(name = 'signin'))
sm.add_widget(SignupScreen(name='signup'))
return sm
def RecordCheck(self):
print("clicked")
def AddToRecord(self):
print("clicked")

Add id attribute both to email and password widgets:
EmailField:
id: email_widget
PasswordField:
id: pass_widget
And you can pass any additional parameters to your method, for example replace:
on_release: app.AddToRecord()
with
on_release: app.AddToRecord(root.ids.email_widget.ids.email_field.text, root.ids.pass_widget.ids.text_field.text)
then change your AddToRecord method definition to:
def AddToRecord(self, email, passw):
print("clicked")
print(f'email: {email}, password: {passw}')

For the email, you can use the get_screen() method of ScreenManager and some ids to access the MDTextField that contains the text. First, add an id to the EmailField:
EmailField:
id: emailfield # added id
hint_text: "Email ID"
pos_hint: {"center_x": 0.5, "center_y": 0.375}
size_hint_x: None
width: "250dp"
Then use that new id and get_screen() to access the MDTextField in your RecordCheck() method:
def RecordCheck(self):
print("clicked")
signinScreen = self.root.get_screen('signin')
email = signinScreen.ids.emailfield.ids.email_field.text
print('email:', email)
Very similar approach can be used to access the password.

How do I make the stacklayout code showup with the kv file code? Or at least make the stacklayout part of the screen.
Right now the only option I have is either take the screen as output or the stack layout as output.
Replacing the def build(self) inside the class FourthWindow(Screen) will show the whole application. The code inside the def build(self) also works but they do not work together.
I am new to kivy and object oriented programming so I do not know much about this topic so I could be missing something really basic.

KivyMD - ScreenManager and ids

How's everyone doing? I am learning about KivyMD and ScreenManager and I have a little problem (and a big one). I was writing a program (like most beginners do) which would allow a user to log in or sign up (I was also practicing about sqlite3, but I don't have a problem with that).
First, I've tried to do everything in only one screen and it worked perfectly!
But now, when I try to use any function, I get:
_username = self.root.ids.my_username.text
AttributeError: 'super' object has no attribute '__getattr__'
The py file is:
from kivymd.app import MDApp
from kivy.lang import Builder
from kivy.uix.screenmanager import ScreenManager, Screen
import sqlite3
class MainMenu(Screen):
pass
class LogIn(Screen):
pass
class SignUp(Screen):
pass
class MainLogSignApp(MDApp):
def build(self):
# Connect to databse an create a cursor
conn = sqlite3.connect('user_pass.db')
c = conn.cursor()
c.execute("""CREATE TABLE if not exists user_name(
username text,
password text
)""")
conn.commit()
conn.close()
return Builder.load_file('mainlogsign.kv')
return sm
def submit_info(self):
'''If the info does not exist, it adds it to the table;
If it does, the function check if it is correct'''
_username = self.root.ids.my_username.text
_password = self.root.ids.my_password.text
# Connect and create cursor
conn = sqlite3.connect('user_pass.db')
c = conn.cursor()
# This should not be necesary, but it is here just in case I delete the table using the DELETE button.
c.execute("""CREATE TABLE if not exists user_name(
username text,
password text
)""")
c.execute("SELECT * FROM user_name WHERE username = (?)", (_username,))
already_in = c.fetchone()
if already_in and already_in[0]:
self.root.ids.my_message.text = already_in[0] + '\nUser already exists'
else:
c.execute("INSERT INTO user_name VALUES (?,?)", (_username, _password))
self.root.ids.my_message.text = 'User added successfully'
conn.commit()
conn.close()
self.root.ids.my_username.text = ''
self.root.ids.my_password.text = ''
# THERE ARE MORE FUNCTIONS, BUT THEY ALL HAVE THE SAME PROBLEM.
if __name__ == '__main__':
MainLogSignApp().run()
And the kivy file is:

None of the functions work, so I'm guessing it has something to do with 'app.function()' or the ids, but it did work the first time. Maybe I have to use a different path, but I don't know.
As a small problem, when I write on the TextInput the hint text doesn't disappear. Any idea why?
Thanks!
BTW, you may notice the button 'DELETE' and 'SHOW RECORDS' and think they have nothing to do with a Login or SignUp program. You couldn't be more right!! So don't pay attention to them. I only added those button to work with sqlite3, but on a real app or site they wouldn't be there. Still, the problem is the same with any button.

Ok, I've solved the problem. I wrote the function submit_info into the SignUp class and change the app.submit_info() to root.submit_info() (in the kv file). Also, I had to remove every "root." in the function.
I hope this works if anybody gets the same problem.

How to change screens from python code in Kivy

So I'm working on making a fully functional login screen for my first serious kivy app and I want to be able to change windows/screens when the user presses on a button. I know normally in the KV file i'd just use on release but I want the on release to call to a method to verify the users credentials, and if those credentials are correct then change screens. So how in python itself would I be able to call to screen manager to change the screen?
from kivy.app import App
from kivy.lang.builder import Builder
from kivy.uix.screenmanager import Screen, ScreenManager
class LoginLayout(Screen):
def login(self, **kwargs):
print("Login function working")
userEmail = self.ids.username.text
userPassword = self.ids.password.text
print(userEmail)
print(userPassword)
ScreenManager.current('emailWindow')
class EmailWindow(Screen):
pass
class WindowManager(ScreenManager):
pass
kv = Builder.load_file('loginScreen.kv')

When a Screen gets added to a ScreenManager, it gets a manager attribute set to the ScreenManager. So in your login() method you can do:
self.manager.current = 'emailWindow'
instead of:
ScreenManager.current('emailWindow')
Note that using ScreenManager, as you do above, references the ScreenManager class, not the ScreenManager instance that is in your App.

How to get user input from an MDTextField in KivyMD

Please guys I really appreciate the help. Thanks in advance...

The email id only appears in the ids for the AccountScreen. Any id appearing in a kv gets inserted into the ids of the widget that is the root of the rule that contains the id. So, you must access the AccountScreen instance to get to the email id:
# BUILDER FUNCTION AND SCREEN
def build(self):
screen = Screen()
# theme settings
self.theme_cls.primary_palette = 'DeepPurple'
self.theme_cls.theme_style = 'Dark'
# end of theme declaration
# loaded strings
self.navigation_bar = Builder.load_string(toolbar) # save a reference to the loaded ScreenManager
# end of loaded strings
# addition of loaded strings to screen + return screen
screen.add_widget(self.navigation_bar)
return screen
# end of addition
# END OF BUILDER FUNCTION
# USER VALIDATION FUNCTION
def login(self):
# use the saved reference to access the email address
email_addr = self.navigation_bar.get_screen('account').ids.email.text
if email_addr == str(''):
print('Invalid Email Address')
# END OF USER VALIDATION

value = self.root.get_screen('nameofscreen').ids.username.text
print("What you typed is: ", value)
syntax = self.root.get_screen('name').ids.id.text
