java.lang.IllegalStateException: представление содержимого еще не создано

"mMatchAdapter" инициализируется при onCreate, но имеет значение null в "setCursor", почему? Этот ListFragment является вкладкой tabHost, я использую его для отображения списка. Я хочу изменить адаптер в setCursor, чтобы отобразить другой список, но возникает ошибка в строке mMatchAdapter.changeCursor(c);, потому что mMatchAdapter имеет значение null, почему? когда getListView выше этой строки, будет
