ExpandableListView с адаптером, отображающий несколько текстовых представлений в одной строке представления списка

Question

Я использую Kotlin для описания ExpendableListview во Fragemnt. Я хочу показать несколько текстовых представлений в одной строке представления списка, и я поместил все свои элементы в массив. Первая позиция для названия продуктов питания Вторая позиция для бренда продуктов питания Третья позиция для калорий в продуктах питания Четвертая позиция для подачи продуктов питания Четыре элемента в группе. Я пробовал Google для ExpendableListview, но все статьи для одного tetview в той же строке.
