How to detect a click on a polyline

Question

If there is a polyline on googlemap and a click is performed on the map, then how can I check whether that click was on polyline or somewhere else?

Polyline          


        

Answer 1

The solution above doesn't work correctly. Especially if we have large distance between two points of polyline.

I answered this question: Clickable Polylines Google Maps API Android

We can modify code above like this:

mMap.setOnMapClickListener(new GoogleMap.OnMapClickListener() {
@Override
public void onMapClick(LatLng clickCoords) {
        for (PolylineOptions polyline : mPolylines) {
            if (PolyUtil.isLocationOnPath(clickCoords, polyline.getPoints(), true, 100)) {
                // user clicked on polyline
            }
        }
    }
});
