私はすべてを検索し、例を追ってみましたが、私はSharedPreferencesを実装することができません。ImageViewはSharedPreferenceに基づいて
私は非常に低い技術のパンチカードを作成しています。 NFCTagには「コーヒー」というテキストフィールドがあります。「サンドイッチ」という別の文字列があります。同じ名前の2つの文字列があります。 Coffee Tagをタップすると、コーヒーイメージが変更され、Sandwichタグをタップすると、そのサンドイッチイメージが変更されます。今
私の質問は、私はそれが設定を保存するために取得することができていますが、それは画像を更新していない、任意の提案は...
https://github.com/soboapps/PunchCardをいただければ幸いです... - これはあなたに何のアイデアを与えることがあり私はやろうとしている。
は、ここに私のコード（私はそれが混乱知っている）

私は上記のコードを更新しました..私はそれがTrueまたはFalseの値を保存していると信じていますが、今は画像を更新していません。ところで、私が更新しようとしている画像は、main_activity.xmlではなくcoffee_fragment.xmlにありますが、私はMainActivityですべてをやろうとしています。すべてがうまく見えますが、私はエラーが発生しない、それは単に画像を更新していないだけです。どんな助けもありがとう。 – Sobo
