I am writing an application that requires me to show routes between a
list of cities. I have been facing difficulties with polylines for a
long time now. I am unable to see any polylines on my map. The
corresponding code for map is listed below.
map = new MapWidget();
map.setHeight("500px");
map.setWidth("600px");
map.addControl(new LargeMapControl());
map.setContinuousZoom(true);
map.setScrollWheelZoomEnabled(true);
map.setSize("100%", "100%");
and
private void drawMap2() {
map.setUIToDefault();
map.addMapType(MapType.getHybridMap());
map.setCurrentMapType(MapType.getHybridMap());
}
I use the Directions API to generate results using waypoints. This is
just a test run of the code. I had earlier tried drawing Polylines
using Polyline(LatLng path) but i faced a similar issue, i.e., no line
on display on map.
public void direct(){
map.clearOverlays();
final Waypoint[] wPoints = new Waypoint[2];
wPoints[0] = new Waypoint("Bangalore");
wPoints[1] = new Waypoint("Mysore");
Timer t1 = new Timer(){
@Override
public void run() {
DirectionQueryOptions opts = new
DirectionQueryOptions(map);
Directions.loadFromWaypoints(wPoints,
opts,visualiseCallBack);
this.cancel();
}
};
t1.schedule(400);
}
DirectionsCallback visualiseCallBack = new DirectionsCallback(){
@Override
public void onFailure(int statusCode) {
Window.alert(""+statusCode);
}
@Override
public void onSuccess(DirectionResults result) {
PolyStyleOptions style = PolyStyleOptions.getInstance();
style.setColor("#00FF00");
result.getPolyline().setStrokeStyle(style);
result.getPolyline().setVisible(true);
System.out.println(result.getPolyline().getLength()/1000);
}
};
So basically markers appear on the map after adding that as overlay
but I haven't managed to make the polyline work between two points.
Can you please help me with what I have missed? Does it work in
Development mode? Could I have missed something in the css or html
file?
