Я создал код для отображения данных из базы данных mysql, он работает, но я не знаю, как создать столбец в виде списка, я использовал линейный макет с вертикальной ориентацией, поэтому он отображает данныеодин за другим, но я хочу, чтобы данные располагались по столбцам, поэтому я пытаюсь изменить ориентацию на горизонтальную, но в ней нет порядка.
я прикрепил вывод, который я получил, а также выводя хочу отобразить.
