I´m looking for a way to set the values of a Kivy Spinner depending on the text chosen from the parent spinner. The problem is that I have defined both spinners in kv language. I´m not sure if the approach would be to destroy the second spinner each time a new value is chosen from the first one, then regenerate it (if so I have no idea how to do that because of the kv code), or if there would be a way to dynamically update the "values" of the second spinner based on an on_text procedure updating the list.
In all cases the below code does not work. Any help appreciated. Thanks.

from kivy.lang import Builder
from kivy.uix.boxlayout import BoxLayout
from kivy.uix.button import Button
from kivy.uix.floatlayout import FloatLayout
from kivy.uix.spinner import Spinner
Builder.load_string('''

anchor_y: 'top'
BoxLayout:
size_hint: 1, .9

padding: 80

class MainScreen(FloatLayout):
def __init__(self, **kwargs):
self.buildLists()
super(MainScreen, self).__init__(**kwargs)
def buildLists(self):
self.pickType = ['Select','#1','#2','#3']
self.pickSubType = ['Select']
def updateSubSpinner(self,text):
if text == '#1':
self.pickSubType.extend('A'+'B')
elif text == '#2':
self.pickSubType.extend('P'+'Q')
else:
self.pickSubType.extend('Y'+'Z')
def onExit(self):
App.get_running_app().stop()
class TestApp(App):
def build(self):
return MainScreen()
if __name__ == "__main__":

You should reference the child spinner values list, not the pickSubType list, which isn't even bound to it. Example:
def updateSubSpinner(self, text):
self.ids.spinner_2.text = 'Select'
if text == '#1':
self.ids.spinner_2.values = ['A', 'B']
elif text == '#2':
self.ids.spinner_2.values = ['P', 'Q']
else:
self.ids.spinner_2.values = ['Y', 'Z']
Writing values: root.pickSubType doesn't bind the pickSubType to the values, if the first isn't a ListProperty. You could upgrade it to a ListProperty if you like, but it is not necessary.

I would like to print button size in console. Able to get root window size, any idea how to get the buttons?
Hoping some way iterate through the widget ids?

I am working on the same issue from my previous post. Now I added screen manager, and I can switch to different pages.
why is my kivy program not calling the function from another class?
I am still confused about OOP with GUIs, however I tried the following, and none of them worked.
I tried to add an instance of Screen 1() in the main app(), and it did nothing. Then, I tried to add the contractor method init into Screen_1() and it says I don't have a build method. And few other ideas that didn't work at all.
Then I realized that there is no link between Screen_Manager() and Screen_1() because all of my methods are in Screen_1(), but the build method is returning Screen_Manager(). On my kv file, there is this code:
<Screen_Manager>:
Screen_1:
Screen_2:
isn't this is where the program "links" between the Screen_Manager() class to other classes?
if someone can help me understand what I am not understanding and help me correct my problem, it would help me to learn about kivy. I understand, <> is like apply to rules, which has 2 widgets screen 1 and screen 2, and also have their own rules.
here is my main.py

thanks again for taking the time to help.
Not sure I understand your question, but pressing Enter in your TextInput executed your code:
self.a.up()
but a in your KeyBoard is the Screen_Manager as set at the line:
self.sm = Screen_Manager()
key = Keyboard(self.sm)
and Screen_Manager has no up method. You can fix that by changing the code in your KeyBoard code to:
self.a.current_screen.up()
Note that this will only work when the current screen is Screen_1.
I'm trying to have self.search_results.data printed on my console, but this is not working. Am I using RecycleView the right way? The textbook I'm studying with is from 2014 and uses ListView. I found on the internet that ListView is deprecated. I can't seem to understand how the RecycleView actually works. I've read the documentation, but still can't see.

Kivy ListView » Deprecated
ListView is no longer defined in the recently released stable Kivy version 1.11.0.
Kivy RecycleView » MVC (Model-View-Controller)
The view is generatad by processing the data, essentially a list
of dicts, and uses these dicts to generate instances of the
viewclass as required. Its design is based on the MVC
(Model-view-controller) pattern.
Model: The model is formed by data you pass in via a list of dicts.
View: The View is split across layout and views and implemented using adapters.
Controller: The controller determines the logical interaction and is implemented by RecycleViewBehavior.
Solution
To create a RecycleView of selectable item, one needs to implement the following classes as part of the viewclass. The item is usually a widget e.g. Label, Button, or a group/row of widgets in a layout (BoxLayout or GridLayout).
viewclass
Selectabel recycle layout class, e.g. SelectableRecycleBoxLayout(), or SelectableRecycleGridLayout()
Selectable widget class, e.g. SelectableLabel(), SelectableButton(), or SelectableRow()
data
Creates a list of dicts for data
Example
The following example illustrates the equivalence of a ListView by using RecycleView. The viewclass is a selectable RecycleBoxLayout of Label widget. The app is using OpenWeatherMap's API to retrieve a sample weather data of London, GB (Great Britain).
Note:
To make calls to OpenWeatherMap using the real API point, you need an API key (APPID).

Output
When I click on the button I need the data from the code to be shown on different screen. Below code does what I need despite that Clock adds widgets every second. I would like the TextInput to be editable so when I type some value to the 'Row' it will stay as typed. I've tried to use Clock.schedule_once() but then the widgets does not appear. I've even tried something like below:
clock = 1
def fill_with_data(self, dt)
if clock == 1:
for item ...
clock +=1
witch locks adding new widgets (ridicules I know) but when I go back to MainScreen to show another data then it does not appear on the screen. Below you will find whole code.

Running the app will produce the following:
Problem 1 - too many Rows instantiated
Rows: as per kv file
Rows() as per Python script in methods show_data1() and show_data2(). These Rows instances created does not have an associated ModalView.
Problem 2 - switched screen before populating list, data
Button:

on_press: root.show_data1()
Button:
text: 'Data 2'
on_press: app.root.current = 'ShowData'
on_press: root.show_data2()
Solution
The following example is just an illustration.
kv file - Add id: rows
Add id: rows to Rows: in class rule, <ShowData>:. This will be use to reference attributes or methods in class Rows().
kv file - invoke fill_with_data()
Use on_pre_enter event of Screen and Clock.schedule_once() function to invoke method fill_with_data()
Note:
Row will be added each time, the screen is displayed. In other words, Row widget will double each time. To prevent this, one might want to delete the widgets added in on_pre_leave event.
Snippets - kv file
<ShowData>:
name: 'ShowData'
on_pre_enter:
Clock.schedule_once(self.ids.rows.fill_with_data, 0.1)
Rows:
id: rows
py file - Access attributes / methods in class Rows()
Get object, app using App.get_running_app()

So, I'm new to kivy and can't get this code to work. I'm trying to update a button text with a popup text input. The popup shows when the button is pressed, and when it's dismissed it should update the text on the button with whatever text was typed in it.
I've tried many variations of this code, but no one have worked. Either nothing happens or I get this error:

Any ideas on how to solve this?
Here is a minimum example of what you are trying to achieve. The hard part is connection the button from the Popup to the Button which opened it. I am going through the app class to achieve that. I got to admit it is not a pretty solution.
from kivy.app import App
from kivy.uix.popup import Popup
from kivy.uix.button import Button
class PopupBttn(Button):
def openPopup(self):
Pop = TextPopup().open(self.text)
class TextPopup(Popup):
def open(self, text, **kwargs):
super(TextPopup, self).open(**kwargs)
self.ids.txtipt.text = text
class MyApp(App):
pass
if __name__ == "__main__":
MyApp().run()
kv file:
BoxLayout:
PopupBttn:
id: bttn
text: 'open Popup'
on_press: self.openPopup()
<TextPopup>:
BoxLayout:
orientation: "vertical"
TextInput:
id: txtipt
Button:
text: "OK"
on_release: app.root.ids.bttn.text=root.ids.txtipt.text
on_release: root.dismiss()
Here is an updated version to use multiple buttons. Unfortunately, you will need to set ids and name to the string of id per Button.
python file
from kivy.app import App
from kivy.uix.popup import Popup
from kivy.uix.button import Button
from kivy.properties import StringProperty
class PopupBttn(Button):
def openPopup(self):
print(self.name)
Pop = TextPopup().open(self.text, self.name)
class TextPopup(Popup):
bttnid = StringProperty()
text = StringProperty()
def open(self, text, id, **kwargs):
super(TextPopup, self).open(**kwargs)
self.ids.txtipt.text = text
self.bttnid = id
def setText(self):
App.get_running_app().root.ids[self.bttnid].text = self.text
class MyApp(App):
pass
if __name__ == "__main__":
MyApp().run()
kv file
BoxLayout:
orientation: 'vertical'
PopupBttn:
name: 'one'
id: one
text: 'I am the first Button'
PopupBttn:
name: 'two'
id: two
PopupBttn:
name: 'three'
id: three
PopupBttn:
name: 'four'
id: four
text: 'I am the fourth button'
<PopupBttn>:
text: 'open Popup'
on_press: self.openPopup()
<TextPopup>:
text: txtipt.text
BoxLayout:
orientation: "vertical"
TextInput:
id: txtipt
Button:
text: "OK"
on_release: root.setText()
on_release: root.dismiss()
In order to update both buttons, you need to assign unique id to each of them. Please refer to the example below for details.
Example
main.py
