Создание двух полилиний разного цвета в Google Maps API Android Studio

Question

У меня проблема с изменением цвета полилинии, можете ли вы помочь мне решить эту проблему ... а также, план состоит в том, чтобы построить две полилинии каждый раз, например (с 7:00 утра -8:00 утра), он построит две линии (север и юг), РАЗНЫЕ ЦВЕТА.Мне трудно искать кого-то, чтобы решить мою проблему, до сих пор я все еще ищу ответ.Помогите мне, пожалуйста.
