アセットファイルへのパスが間違っているように感じますが、使用する正しいパスがわかりません。テキストファイルが実際にどこにあるかを再確認しましたが、assetsそのようなファイルまたはディレクトリがないというエラーが原因で、間違ったファイルまたはディレクトリが原因であると思われるのはなぜですか？
さまざまなフィールドを格納するために使用される質問コードの周りにラップされた条件付きコードがあります。このコードは、配列に4つに等しい要素があるかどうかを指定し、ファイルからのデータを配列リストに入力します。この条件が満たされない場合、ログにはエラーが表示されます。ファイルの名前は
- quiz1.txt
- quiz2.txt
- quiz3.txt
これがLogCatです
