Multiple Screens But Self.root.ids Retuns An Error

This code actually worked until I added multiple screens. It still works when I remove the multi Screen Manager. I get the attrubite error point to Chapter ids Im trying to add a

Solution 1:

The line:

self.root.ids.Chapter.add_widget(OneLineListItem(text=filename[2:],
                                                     on_release=self.play_song,
                                                     pos_hint={"center_x": 1, "center_y": 1}, ))

is trying to reference the Chapterid as if it were a member of the ScreenManager (root) ids, but it is not. It is a member of the ids of the BookScreen. You can fix that error by referencing the BookScreen instance in the problem line using the get_screen() method of ScreenManager:

self.root.get_screen('BooksScreen1').ids.Chapter.add_widget(OneLineListItem(text=filename[2:],
                                                     on_release=self.play_song,
                                                     pos_hint={"center_x": 1, "center_y": 1}, ))
