動的に生成されるチェックボックスの詳細をmysqlに保存する方法

Question

私はアンドロイドで出席アプリケーションを実行しようとしています。ユーザーがテキスト編集コンポーネントにセクションを入力すると、学生のリストがmysqlデータベースからチェックボックスチェックボックスにはすでにチェックされているチェックボックスがありません）チェックボックスをオフにすると、生徒は不在として保存する必要があります。そうでなければ生徒はpresent.Canの誰かに詳細を保存するコードを実装する方法を教えてくださいチェックボックス（つまり、存在するかどうか）をmysqlデータベースに保存します。

ありがとうございます。

1. 使用setTag（）とチェックボックスを識別するためのgetTag（）メソッド。私のコードの学生の名前とチェックボックスで

    // set the ID before rendering 
        chcekbox.setTag(ID); 
   
        // get the ID when this method called "onCheckedChanged"(before storing into the database) 
        buttonView.getTag();
