[Android][Google Maps]: Get the Address of location on touch

阅读更多关于 [Android][Google Maps]: Get the Address of location on touch

I have been googling this for hours but no luck so far. I want to get the address of the location where the map is touched / tapped. I understand that in order to get the address i need to reverse geocode the coordinates. But how do i get the coordinates from the map in the first place?

Then, use a Geocoder object to get the address of the point that was just clicked on. In this simple example, I've also added a Marker every time the user clicks a new point on the map. Here is

How can I extrapolate farther along a road?

阅读更多关于 How can I extrapolate farther along a road?

问题 Given realtime location data of a moving device over a short period of time, how can I get a lat/long pair further along this road, say, 2 miles, or even better, 5 minutes worth of driving? I see that I can use Google's Roads API to snap to a road given a lat/long pair https://developers.google.com/maps/documentation/roads/snap, but that only gets me part way there. This will be in an Android app. 回答1: Given a route represented as a List<LatLng> , this function calculates the point on the
