mapbox-android - Mapbox 导航关闭路线检测不起作用

Question

我正在尝试在 mapbox 导航中测试偏离路线检测，但它不起作用。我已经跟踪并调用了 OffRouteDetector.isUserOffRouteWith，但 status.getRouteState() 只返回“INITIALIZED”（这不是预期的 RouteState.OFFROUTE）

我怀疑我遇到了一个边缘情况，因为我正在使用起点和终点距离我当前位置很远的旅行。因此，它永远不会“开始”。但是，这是我的应用程序中的一个有效场景（它涉及由于公共安全问题而无法更改的存储路由）。

我在 github 上提出了一个问题（已关闭），但对于背景，它就在这里

编辑：这是一些更接近我想要做的代码。这是来自默认 android studio 项目的 MainActivity 的 onCreate ：

Answer 1

@Troy Berg 让我花点时间解释一下在加载新路线时，跟随代码的路线如何在内部工作。

加载新路由时，如果路由 json 有效，MapboxNavigator则将在该INITIALIZED状态下启动。从那里它将尝试获得信心，即传入的 GPS 位置实际上是用户所在的位置。为了建立这种信任，它需要至少接收一些位置更新，并且这些更新必须在时间和空间上都是一致的。在建立这种信任的过程中，它将报告INITIALIZED状态。

一旦建立了对用户当前位置更新流的信任，MapboxNavigator将尝试测量用户沿着当前加载的路线的进度。如果发现用户的位置与路线本身的距离不合理，则将状态翻转为OFFROUTE状态。

如果用户的当前位置与当前加载的路线在合理的距离内，但距离不足以被视为在路线上（TRACKING），我们将继续返回INITIALIZED状态并等待用户前往路线。我们称之为畜栏。例如，Corraling 允许用户在他/她的车道或商店的停车场加载路线，而不是立即被标记为OFFROUTE。在圈养时，如果用户不断地远离路线，他们最终会被标记OFFROUTE。
