I'm just writing an App for displaying the route between two coords (lat, long) in google maps view. Displaying an single coord (even with a marker) works fine, but how to draw route between two point with 2 markers?
我正在编写一个应用程序，用于在谷歌地图视图中显示两个坐标（纬度、经度）之间的路线。显示单个坐标（即使使用标记）工作正常，但如何使用 2 个标记在两点之间绘制路线？
I must admit that I'm quite new to Android and the maps-API...
我必须承认，我对 Android 和地图 API 还很陌生……

this is working example link. check it out. it helps to create the route overlay on the map. here is the complete sourcecode for that.

Your route will be a list of points so you have to create a route overlay class. And in the draw method of the overlay class you have to draw a Path between the points.
您的路线将是一个点列表，因此您必须创建一个路线覆盖类。并且在覆盖类的绘制方法中，您必须在点之间绘制一条路径。
