내 데이터베이스에있는 위도와 경도 값을 가진 여러 마커를 표시하려고하지만 문제는지도에서 하나의 마커 만 표시한다는 것을 의미합니다.지도를 통해 다중 마커를 표시하는 방법

괜찮 이것은이다 : 조건이 참 PLZ 나에게 여기
지도
에 마커 여러 위도의 가치와 LNG 어떻게 보여줄 수있는 솔루션을 제공한다 나의 코드 10.0.2.2:51220/Service1.svc/getLat 의 출력output:
<ArrayOfTrafficConditions>
<TrafficConditions>
<Lat>27.0006748</Lat>
<Latitude>27.0006748</Latitude>
</TrafficConditions>
<TrafficConditions>
<Lat>64.700064</Lat>
<Latitude>64.700064</Latitude>
</TrafficConditions></ArrayOfTrafficConditions>
이 난 그냥 내 안드로이드 응용 프로그램에하지 만 위도 긴 값을 전달하려는
namespace JSONSample

public class DataAccess

{
List<TrafficConditions> Lat= new List<TrafficConditions>();
{
con.Open();
SqlCommand command = new SqlCommand("SELECT DISTINCT Latitude FROM TrafficConditions ", con);
SqlDataReader reader = command.ExecuteReader();
while (reader.Read())
{

loc.Latitude = Convert.ToDouble(reader["Latitude"]);
Lat.Add(loc);

이제이 코드에서 위도와 경도 값을 가져 와서 여러 마커를 표시하는 방법은 무엇입니까? u는 나에게 모든
괜찮아요하지만 다른 위도와 위도와 함께 내 데이터베이스에 저장된 http를 통해 여러 마커를 표시하고 싶습니다 내 코드가 뭐가 잘못 됐는지를 지적 할 수 있을까요? 그것의 일을 잘하지만 단지 하나의 마커를 보여주는 – Yumna
