チェックボックスをクリックするたびにTOASTをリストビューに表示する必要があります。リストビューでチェックボックスをオンにするたびにTOASTをどのように表示しますか？

私はボタンをクリックした場合の方法showResultTotale2（）は動作しますが、私が上で動作し、同じ方法をしたいすべてのチェックボックスをクリックしてください：
は、これは私のコードです。
誰が私を助けることができますか？ありがとうございます！

あなたの問題は、本当に多くの明確ではありません。また、関連コードのみを共有する – Shaishav
ボタンをクリックすると、showResultTotale2メソッドが機能します。しかし、私はボタンではないすべてのチェックボックスをクリックすると、このメソッドが動作するようにしたいです – Markus
あなたはいくつのチェックボックスを持っていますか？リスト項目にチェックボックスがあります（アダプタにチェック・チェンジ・リスナーが表示されているため）。 – Shaishav
