上記のコードに誤りはありますか？ case position == 2はgetItemViewType()で実行されていませんか？
私はデバッグしようとしましたが、positionは常に0または1となります。
ここでは、単一のビューホルダーを使用しています。私がやっていることは、isFromMallの条件がtrueの場合、ビューの表示/非表示です。リサイクラー・ビュー・アダプターで3つのビュー・タイプを使用できますか？
返信いただきありがとうございます。私の質問が更新されました。ここで紛失しているものが見つかりましたか？ –
私は位置変数が0と1だけを返すと思います。位置を変更してその位置を返すためにgetitemviewtypeのカスタムメソッドを使用してください。 –
