リサイクラービュー内に行を作成し、その中に2行以上を膨らませましたが、スクロールすると、アイテムが再び使用されるようになります。ビューをリサイクルしたり動的に削除したりする場所を取得していません。フィードとそのコメントが必要です。コメントの場合は、getCommentInflaterViewメソッドが作成されたフィードの下にレイアウトを表示してレイアウトを膨らませる必要があります。
ただし、getCommentInflaterView()を使用して作成されたビューは複製されます。 MyAdapterClass:

アダプターでこれら2つのメソッドをオーバーライドします。
@Override
public long getItemId(int position) {
