당신이 위도와 경도의 Array_list합니다 -

당신의 도움에 대한 모든 감사의이

arraylist_lat_lon.add(new LatLng(location.getLatitude(), location 
        .getLongitude())); 

      /************************** Drawing polyline if there are more than 1 latlngs **************/ 
      if (arraylist_lat_lon.size() > 1) { 

       PolylineOptions polyline_options = new PolylineOptions() 
         .addAll(arraylist_lat_lon).color(Color.GREEN).width(2); 

       polyline = googleMap.addPolyline(polyline_options);
