Получение необработанного значения ячейки выбранной строки в сетке

* Я уже работал над обновлением пути полилинии без удаления полилинии. Мы можем это сделать, изменив точки этой полилинии. Проверить код ниже.

Это логика установки новых точек на полилинию.

/*Here the routes contain the points(latitude and longitude)*/
for (int i = 0; i < routes.size(); i++) {
            Route route = routes.get(i);
            if(polyline_path != null){
                polyline_path.setPoints(route.points);
            }
        }

Подробное объяснение:

private GoogleMap map_object;
private Marker marker_driver;
private Marker marker_drop_off;
private Polyline polyline_path;
private PolylineOptions polylineOptions_path;
