推荐答案
我不认为有这样做的任何合理的方式。需要注意的是谷歌没有这样做无论是在自己的地图应用程序。这是pretty的明确只是在看网页，看瓷砖仍在加载，所以我不认为有任何实际需要投入进度指示器。
I don't think there is any reasonable way of doing it. Note that Google isn't doing this either in their map applications. It is pretty clear just looking at the page to see if tiles are still loading, so I don't think there is actually any need to put in a progress indicator.
的<一个href="http://$c$c.google.com/android/add-ons/google-apis/reference/com/google/android/maps/MapView.html"相对=nofollow>图形页面有一个方法 canCoverCenter（）这可以告诉你，如果该中心的瓷砖是可用的，但并没有什么针对的休息瓷砖。
The MapView has a method canCoverCenter() which can tell you if the center tile is available, but there is nothing for the rest of the tiles.
