For better optimization, I decided to use the RecycleView in one part of my program to hold a set of DownloadItem instances. The problem is that the class takes two arguments: path & url_type which I do not know how to pass to the data of the recylceview. As a result I get the error below:

This Has To One OF The Most Annoying Errors In Python That Have So Many Solutions Depending On The Question

I need help.

I created a small mobile application with Kivy.

I have two screens: ScreenList and ScreenDetail.

However the screen(ScreenList) containing GridLayout does not refresh

ScreenList: contains a list of items

ScreenDetail: Contains the details of a single item.

How the app works:

1. When I click on the first item on button 1
2. I go to the details of the item.
3. I modify the second field. I replace the text: Firt element for First and update data
4. After recording, I redirect the application to the screens which contain (ScreenList) the list of elements.
5. But the list of elements remains unchanged then the data has been modified in the database. 6.And when I return to the screen (ScreenDetail) which contains the details, there I see that the data is updated.

How can I refresh the item list in ScreenList?

Here are the pictures as an example

List before update

after update

List after update

Here is the python code:

I am using KivyMD and I am trying to get the text from the text input in kivyMD. I keep getting the following error:

I am making a desktop application using kivy & kivymd and when creating the settings screen for the app I used two MDRectangleFlatButon and MDRaisedButtons but to make them scalable, I gave both of them a size_hint_x of .5 for each to take up half of the screen. However, as soon as the program starts I get this warning from kivy:

I could really really need some help with my actually quite simple Python Kivy Problem! I wrote a program that first announces counting to 5 and then should start counting from 1 to 5. The info should be shown in a scrollview-Label. The code roughly does its job but does not update the scrollview step-by-step but all at once after time is elapsed...can anybody please help? Thank you in advance!

How to make text that I enter in the TextInput field (textA) will show in the Label (labelA) by using a button?

Every time there is new inputs, when the button is clicked, the labels will show the latest inputs.

Problem here when I use: self.textA = TextInput(text='ss')

When I type new text and I click the button, the label always show 'ss'. Its not updating the new input.

Hope someone can show the method - just in python, not the Kivy Languange

Thanks
