How to enable traffic information along a specific route in Google Maps V2?

问题

Google Navigation shows the traffic layer only for a given route. With GoogleMap.setTrafficEnabled(true) I'll get the traffic information for the whole map.

I know how to draw polylines for a route from Google Directions, but how can I turn on the traffic layer only for that route?

回答1:

Not possible as of API v2 version 3.1.36. You may want to post a feature request on gmaps-api-issues.

回答2:

The difference between these two values (duration and a duration in traffic) indicates how delayed your customer is going to be on their way to or from their location.
