2つの画像ビュー（imageView & imageTwo）と4つのボタン（各画像ビューのtakePhotoとselectPhoto）があります。各ボタンをタップすると、撮影または選択した写真が対応する画像ビューに表示されます。すばらしいです。同じ画像を2つの別々のフィールドに保存していますか？
ただし、私は2枚の写真をデータベースに保存しようとしています。何らかの理由で、撮影した最初の写真が2つの異なるデータベースフィールドに保存されます（同じ写真が2つの別々のフィールドに保存された写真の代わりに両方のフィールドに表示されます）。つまり、データは正しく保存されているようです（XML出力を参照）。
これはなぜですか？以下のコードを参照してください（長い投稿には申し訳ありません）。保存時に
