3つの断片の単一アクティビティがクラッシュする

私は認証アクティビティを作成しました。これは、ユーザが使用したい対応するフラグメントを置き換えるコンテナとしてFrameLayoutです。3つの断片の単一アクティビティがクラッシュする

容器内の最初の断片はLoginFragment又はSignUpFragmentに移動するロゴと2つのボタンの背景、ImageViewのとちょうどConstraintLayoutあるWelcomeFragment、です。

問題は、私はLoginFragmentにWelcomeFragmentから行くとき、バックWelcomeFragmentに来SignUpFragmentに行き、そしてWelcomeFragment、再びカムバックしよう、ということですアプリケーションがクラッシュし、私に次のエラーを与える：

削除し、以前のすべての断片、あなたの関数にpopBackStackImmediateメソッドを使用する必要はありませんreplaceFragmentInActivity()

findFragmentByTag(String tag)を使用して、指定されたフラグメントが存在するかどうかを調べ、トランザクションをスキップすることをお勧めします。

ありがとうございました！コンテナ内のすべてのフラグメントを1つではなく置き換える方法がわかっていませんでしたが、今ではReplaceFragmentが廃止された理由を理解しています。提案したようにfindFragmentByTagを使用するように自分のコードを更新し、popBackStackImmediateを使用して既存のフラグメントを回復しました。それは今素晴らしいです！再度、感謝します。 – Pujolsluis
