黑莓地图问题
我在黑莓上尝试了这个示例并得到了结果（两个位置之间的距离正确，如示例中所述）。
但运行代码后，我可以看到道路，但看不到道路后面的地图，
这是描述我的问题的图片
那么问题出在哪里？因为我在测试的每个地图应用程序中都遇到这个问题。

您在真实设备上尝试过吗？我的经验表明，OS5 模拟器下载/显示地图的能力极其不可靠。您还可以尝试 OS6 模拟器——我在这些方面的运气要好得多。
Have you tried on a real device? My experience has shown that the OS5 simulators are extremely unreliable in their ability to download/display maps. You could also try an OS6 simulator -- I have had much better luck with those.
