python kivyのrecycleviewについて

Question

前提・実現したいこと

pythonのkivyでToDoアプリ的なものを作ろうとしています。そこで、RecycleViewを使って登録したToDoを表示させようとしているのですが写真のように二重になって表示されてしまいました。どうしたらいいかわからず躓いてしまいました。
どうすればいいかアドバイスもらえるとありがたいです。

Answer 1

todo.kvが二度読み込まれているのが原因ですね。

一つはBuilder.load_file('todo.kv')。
もう一つはKivyがAppclassの名前から自動で読みこんでます。

なので解決策は

1. todo.kvの名前を変える
2. Builder.load_file('todo.kv')を消した上でsmの作成を全てbuild()method内で行う

のどちらかです。
