Как показать панель контекстного действия из адаптера списка?

Question

Я создатель noob для разработки Android, и я пытаюсь отобразить CAB от List_Adapter, когда пользователь нажимает кнопку на элементе списка. Я следую ActionbarSherlock sample, но не могу понять, почему я получаю ошибку «Метод startActionMode(Child_Locations_ListAdapeter.AnActionModeOfEpicProportions) не определен для типа Child_Locations_ListAdapeter». Любая помощь приветствуется.

Метод startActionMode привязан к деятельности, а не к ListAdapter

http://developer.android.com/reference/android/app/Activity.html#startActionMode(android.view.ActionMode.Callback)

((Activity) c).startActionMode(new AnActionModeOfEpicProportions());
