私はexpanablelistview（グループビューと子ビュー）でチェックボックスを実行しようとしています。しかし、私はこの概念を理解していません。皆さん、何かアイデアがあれば、私と共有してください。このコンセプト（expanablelistview）で作業するのはこれが初めてです。
グループビューのチェックボックス(CheckBox checkBoxGroup )
- groupview(groupposition 0) のチェックボックスをオンにすると、child(childposition 0) のすべての項目をチェックする必要があります。
- groupview(groupposition 0) のチェックを外した場合と同じように、child(childposition 0) のすべてのアイテムをオフにする必要があります。
チャイルドビューのチェックボックス(CheckBox checkBoxChild ;)
- チェックボックスで複数選択するだけです。
あなたの親切な助けに感謝します。
ここに私のコードがあります
