Я использую два типа файлов: файл .txt, в котором я извлекаю координаты, используемые в координатах карты, и ArrayList, который присваивает код (строку) каждой путевой точке. У меня также есть файл .csv, в котором я получаю 2 строки. Эти две строки представляют собой путевые точки для связи, и эти строки соответствуют двум кодам, которые обычно уже используются для названия путевой точки.
Я пытаюсь создать линию между различными путевыми точками. на основе файлов .csv.
Мой код:
