Android Map View問題

Question

我有一個跟蹤用戶地理位置的應用程序。我只需獲取這些點並使用它們在地圖視圖上繪製路徑。

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. 

請幫忙。 :) 在此先感謝。

使用MapController.zoomToSpan(...)，您可以從您的ItemizedOverlay方法getLatSpan(int)和getLonSpan(int)獲得範圍。 zoomToSpan（...）是一種盡力而爲的方法，並不保證所有點都可見。
