问题
I am new to Android google maps APIs. I am learning it from this TUT : http://mobiforge.com/developing/story/using-google-maps-android but there isn't any mention of getting the direction between 2 points. Is there any APIs can do this task in http://code.google.com/android/add-ons/google-apis/reference/index.html ?
Thank in advance !
回答1:
Google maps API does not provide any routing capabilities. You can use an intent to fire the google navigator (assuming it's on your device) or the the google maps version (as mentioned by Hwa Rang)
There are some tutorials to do this outside of the API, but be advised the google prohibits implementing turn by turn navigation, apparently simple routing is ok though.

There is an intent to the Google Maps app you can use.
Intent i = new Intent(android.content.Intent.ACTION_VIEW, Uri.parse("http://maps.google.com/maps?saddr=" + saddr + "&daddr=" + daddr));
