これは私のアダプタの問題はどのように解決するためにすべての位置でtextviewの値を変更するスクロールリストビューでしたか？プラスイベントをクリックすると、マイナスイベントがテキストビューでデクリメントされ、値が設定されます（Plusをクリックして数量+1、数量をクリックするとマイナス1になります）。Textviewのカスタムリストビュー

実際にはどうなりましたか？ –
この '@Overrideを置き換えます。 public int getViewTypeCount（）{ return 1; } '@Overrideを使用している場合 public int getViewTypeCount（）{ return getCount（）; } ' –
