android - 谷歌地图 API : how can I get the departure platforms for public transport?

Question

我想在我的 Android 应用中显示公共(public)交通工具的出发站台，例如火车。

数据是可用的，因为使用谷歌地图网站向我显示了火车从哪些平台出发，但我还没有设法从 DirectionsResult 对象中检索到这些数据。

有人知道怎么做吗？

更新:尝试使用 postman 检索数据导致以下对象，如您所见，没有火车步的出发站台数据，而此数据在 google map 网站或应用程序本身中可用。

很遗憾，目前无法通过 Directions API 获得此信息。 Google 问题跟踪器中有一个添加 2016 年创建的登机平台信息的功能请求:

Google 似乎没有为这项任务设置高优先级。请随意在 Google 问题跟踪器中为功能请求加注星标以添加您的投票。希望有一天 Google 会实现它。
