Android - 如何通过路线路线导航？

Question

I'm building an app which will show route to the user to specific destination. I get the route from Google direction web service.

But I don't understand how should I know in which leg the user is now? Or, which legs have already been passed?

Answer 1

The way to find out the leg in which user is currently positioned is to find the values in the steps[] array, if those steps match with another steps[] array in one of the leg than that particular leg is the one in which the user is currently located.

Code logic would have some conditional if else statement where a check would be made to figure out the steps in one of the leg fetched from the API and the steps user currently is.

Hope that Helps!!
