확인. 나는 자바 또는 안드로이드 프로그래머가 아니지만 버스 정류장을 보여주는 버스 경로가 특정 색상과 마커를 사용하여 중복되는지도 앱용 코드를 작성합니다. 코드는 작동하지만 버스 길을 따라 가려면 더 많은 포인트가 필요하며 주로 마커와 폴리 라인에 대한 LatLng 값이 다른 동일한 코드가 필요합니다. 나는 XML을 배열과 루프로 파싱하는 것으로 생각한다. 그러나 : 1) 많은 튜토리얼을 따른 후에 내가 원하는 방식으로 어떻게해야하는지 모르겠다. 2) 필자가 원하는대로 외부 XML을 사용하지 않기를 바란다. 너무 많은 인터넷 deppendant을 할 수 있습니다 (전용 캐시에 대한지도, 또는 업데이트 노선의 XML의)XML을 구문 분석하여보다 효율적인 코드를 작성 하시겠습니까?
