フラグメントA、B、C、D、Eを持っています。例えば、フラグメントAが表示されている場合、私はB、C、D、Eを隠します。同じことをBをクリックするとフラグメント、A、C、D、Eが隠されます。戻るボタンを押して、私が望むやり方で機能させるようにしてください。そうすれば、ユーザーが別のフラグメントに切り替えるたびに、フラグメントをバックスタックに追加します。しかし、私が抱えている問題は、戻るボタンを押すと、以前のすべての断片がすべて一度に表示されるということです。電話で狂っているように見えますが、とにかく、この問題をどのように修正できるかアドバイスできますか？すべてのフラグメントは、Androidで戻るボタンが押されたときに表示されます
