Android 地图视图问题
我有一个跟踪用户地理点的应用程序。我只是获取这些点并使用它们在地图视图上绘制路径。
My issue is, when I see the path tracked by user, the path seems to be correctly plotted but, when I have a first look over the map,it does not show me an entire zoomed out view of the map where I can see all the track path. Instead the map begins with from where I started tracking and then I need to scroll all my way to see the further tracks.
请帮忙。 :) 提前致谢。
I am having an app which tracks the Geopoints of the user. I simply fetch these points and use them to draw the path on Map View.

Please Help. :)
Thanks In Advance.

使用 MapController.zoomToSpan(...)，您可以从 ItemizedOverlay 方法获取跨度 getLatSpan （整数） 和 getLonSpan （整数）。 ZoomToSpan(...) 是一种尽力而为的方法，并不保证所有点都可见。
Use MapController.zoomToSpan(...), you can get the span from your ItemizedOverlay methods getLatSpan(int) and getLonSpan(int). zoomToSpan(...) is a best effort method and does not guarantee that all points will be visible.
