我想在我的 Android 应用中显示公共(public)交通(例如火车)的出发站台。
由于使用谷歌地图网站向我显示了火车从哪些平台出发，因此数据可用，但我尚未设法从 DirectionsResult 对象中检索此数据。
有人知道怎么做吗？
更新: 尝试使用 postman 检索数据会产生以下对象，正如您所看到的，没有火车步骤的出发平台数据，而这些数据可在谷歌地图网站或应用程序本身中找到。

最佳答案
遗憾的是，目前无法通过 Directions API 获取此信息。 Google 问题跟踪器中有一个功能请求，要求添加 2016 年创建的登机平台信息:
https://issuetracker.google.com/issues/35829155
看来 Google 并未高度重视这项任务。请随时在 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 能够实现它。
