私は2種類のユーザーが存在するAndroidアプリケーションで作業しています。ユーザーがシステムにサインアップまたはログインすると、ユーザーは同じホーム画面にリダイレクトされ、その種類に応じて異なるビューの断片が膨張します。初めてのサインアップ時にShared Preferencesを使ってこれを達成できました。私の唯一の問題は、ユーザーがサインアウトして再びログインしようとすると、彼がどんなタイプのユーザーであっても、同じホーム画面がロードされることです。私は、アクティビティが最後のセットの共有設定を使用しているかどうかは疑問です。共有設定は常に同じ値を返します
私の断片では、userTypeに基づいて、対応するxmlファイルを膨張させます。私の要件は、ユーザーがサインインすると、対応するXMLファイルieをどのように膨張させるかです。 SignInActivityのShared環境設定を取得して、対応するフラグメントxmlをロードするにはどうすればよいですか。
これまで私がこれまでに試したことは次のとおりです。

アプリにユーザーがサインインが、どのように私は、各フラグメントのXMLをロードする？私は何が欠けていますか？親切に助けてください。
