共有設定の問題に直面しています..
私のアプリケーションでは、クイズの答えを保存するために共有設定を使用しています..
私が試してみました。私が周到な質問に来たとき、それはうまく動作します..しかし、私の問題は..
1 番目の質問でユーザーが回答を選択して 2 番目の質問に進むと、ここでもユーザーは回答を選択し、賢明なプロセスのように 3 番目の質問に進みます。正しく、ユーザーがこの時間までに次に進むと、答えが正しくチェックされません...私は何を間違えましたか?
私を指摘してください..そしてそれを得る方法を教えてください。事前にどうもありがとう..
私の悪い英語でごめんなさい..
これが私のコードです..
