Multi Selectでリサイクルビューを実装しました。シングルクリックとダブルクリックを識別して選択するためにaddOnItemTouchListenerを使用して正常にリサイクルビューを実装しました。しかし、私はより多くのデータを持っているとき、リサイクラビューがビューのリサイクルを開始すると正確に、私の選択は狂ってしまい、differnt possitionを選択します。私はクリック位置を見るためにログアウトしました。これは、プログラミングに私の選択wrong.I'm新を行い、Androidアプリにdevelopment.Can誰もがこれをたくさん取ると、私を助けて、ここに私のコードでくださいRecycler Viewマルチセレクションを実行しているときにView Itemを間違って選択

あなたは私を詳しく説明し、啓発してくださいできないonItemClick –
にonBindViewHolderであなたのロジックを追加する必要があり –
RecyleViewを@MuthukrishnanRajendranしてください常にビューを再利用し、あなたはonItemClickにすべての設定されていますが、新しいオブジェクトをスクロールを開始したときになります既存のオブジェクトを作成または変更して新しいアイテムを完成させます。ですから、あなたはonBindViewHolderのすべての変更を行うべきです。 –
