Kivy Screen Problems

[Bahaddin Şarman]

I used multiple screens in my project and added a navigation bar to my 4th screen. However, when transitioning between the navigation bar items, the text in the 'Settings' screen overlaps with the text from the 'Home' screen. I had a similar issue with the swiper as well. I’m sharing my project code. I would really appreciate it if you could help me. Thank you in advance.

I've not had the time to investigate your issue.  I suggest you create a minimal example.  It looks like you may have instanced the HomeWindow screen multiple time.

The problem is your kv file is being loaded twice.

Notice the error in the log: [WARNING] [Lang        ] The file C:\Users\ellio\PycharmProjects\KivyHelpv230\eticaretbaris\main.kv is loaded multiples times, you might have unwanted behaviors.

Kivy will try to automatically load a kv file with the same name as the App.  Your app is named "MainApp", and the kv file is named "main.kv".  You are also manually loading the kv file.

Remove the line:

return Builder.load_file("main.kv")

that is found near the bottom of your main.py file.  This will fix the issue. 

This behavior is described here: https://kivy.org/doc/stable/api-kivy.app.html#kivy.app.App.load_kv

It is also described in the example here: https://kivy.org/doc/stable/api-kivy.app.html#method-using-kv-file
