Your assumption that Collections.sort( returns the sorted collection is wrong. mAdapter = new CoursesItemAdapter(getActivity(), R.layout.catalog_list_item, Collections.sort(parserJson.getCourses(), new CoursesPriceComparator())); it should be ArrayList< CoursesData > data = parserJson.getCourses(); Collections.sort(parserJson.getCourses(), new CoursesPriceComparator()) mAdapter = new CoursesItemAdapter(getActivity(), R.layout.catalog_list_item, data); Collection.sort return type is void.
