Вот в чем дело..
У меня есть одно действие, в котором я реализовал ActionBarSherlock, View Pager с навигацией по вкладкам.
В панели действий я разместил представление поиска. Теперь я добавляю список фрагментов из действия, используя viewPagerAdapter.
Теперь во фрагментах я разместил расширяемый список и отображаю продукты с именем раздела в расширяемом списке.
Чем я хочу заниматься ::
Я хочу выполнить поиск продуктов из расширяемого списка.
Проблема, с которой я столкнулся ::
Я поместил представление поиска в действие, из которого я вызываю разные фрагменты. Итак, как выполнить поиск???
Мой код ::
