推荐答案

你是什么意思为您的设备的举动？无论哪种方式，您在使用位置监听器来获得位置更新，并在每一个新的更新创造新的更新的坐标和previous一个之间的折线。

what do you mean as your device move? either way you have to get location updates using location listener and on every new update create a Polyline between the coordinates of the new update and the previous one.

更新：这里有一些帖子，告诉你如何绘制折线与方向：

UPDATE: Here are some post that show you how to draw a polyline with direction:
