私のアプリを起動すると、すべてのチェックボックスはlist viewに選択されています。だから、すべてのチェックボックスの前にチェックをはずす必要があります....私は理由を知らない..... 多分私はonDestroyメソッドを書くに間違っています....onDestroyは機能しません
私を手伝ってください！
私はあなたに私のコードを示しています... おはようございます！

'onDestroy'メソッドでlogステートメントを追加して、' onDestroy'が確実に呼び出されるようにしてください。呼び出されると、ステートメントが表示されます。私の更新された答えを見てください。 – ishmaelMakitla
ログは私の本物のinfactのチェックボックスを選択する.... – Mark
