Google Map API v2 - Get Driving Distance from Current Location to Known Locations

阅读更多关于 Google Map API v2 - Get Driving Distance from Current Location to Known Locations

I'm trying to figure out how to display the driving distance from the current location to four known locations. I'm not showing a map on the screen, I just need to display how many miles away the user currently is from those locations. I took an example from Here and modified it a little. It is bringing back the correct distance but I can't figure out how to pass in each of the 4 end locations, or differentiate between them. What do I need to do in order to get the distance to each of the 4 locations and display each of those distances in separate TextViews? Update question: How do I calculate

Draw circles of constant size on screen in Google Maps API v2

阅读更多关于 Draw circles of constant size on screen in Google Maps API v2

I'm working on an Android Application using Gooogle Maps API v2. I have markers on my map, and I'd like to circle one of them. I managed to do that easily, by using the Circle and Circle Options classes. But I'd also like my circle to keep the same size on the screen when zooming or unzooming, just like the markers do. It means that the circle must have a constant radius in terms of pixels. Sadly, we cannot set a radius in pixels in the API v2. I have tried several solutions, but I'm not satisfied. In the first one, I just multiply or divide the radius : @Override public void onCameraChange

Map of MapFragment gets loaded with lag when returning from another activity

阅读更多关于 Map of MapFragment gets loaded with lag when returning from another activity

问题 As far as I can see, MapFragment has an issue with transition animations. All views on the layout are getting shown immediately, including the MapFragment's own views (like zoom buttons). But the map itself gets loaded with a lag only after the animation is completed. In order to illustrate the problem, I did the following: I changed one of the Activities in the Google maps android API examples slightly. It opens a blank activity via an Action Item. When I click back button, the map gets

Draw Text on Google Map no longer possible?

阅读更多关于 Draw Text on Google Map no longer possible?

I'm upgrading an Android application from version 1 to version 2 of the android google maps API. In my version 1 code, I was able to draw text directly on the map in my subclass of ItemizedOverlay by overriding the draw() method, as follows. The text I want to draw is dynamic, an additional text item that I want to display next to each map marker, so the text will be added/removed frequently as different symbols are plotted / removed. @Override public boolean draw(Canvas canvas, MapView mapView, boolean shadow, long when) { if (!shadow) { canvas.drawText("some text", (float) point.x +
