Witam! Mam listview, gdzie wyświetlam 2x arraylist(bitmap + string) w jednym rzędzie/wierszu. Schody zaczynają się przy sortowaniu. O ile sortowanie string działa bez zarzutu o tyle problem jest z obrazkami tzn wyświetlenie arraylist obrazkami w takiej kolejności jak ten posortowany ze stringami(żeby obrazek pasował do wpisu, do którego został dodany jako załącznik, przez użytkownika). Wymyśliłam coś takiego jak poniżej( 3 ostatnie ify metody Sort()). Niestety wyrzuca mi następujący błąd.
