未触发偏离路线
我正在使用导航启动器.我也尝试过使用导航视图.但是没有触发useroffroute功能.
I am using navigation launcher.I have tried using navigation view too.But the useroffroute function is not getting triggered.

我希望被我覆盖的功能useroffroute被触发.但是没有触发发生，因为当用户偏离路线时无法看到Toast消息和文件创建.
I expect the function useroffroute overridden by me gets triggered.But no trigger happens as in am not able to see the toast message and file creation when the user goes offroute.
推荐答案
因此，这里要解决的第一件事是，这绝对不适用于 NavigationLauncher .该对象实际上是一个功能全面的解决方案，可通过最少的自定义快速启动和运行.因此它不够灵活，并且不允许您修改 offRoute 侦听器.这只能通过 NavigationView 来实现.
So the first thing to address here is that this will definitely not work with NavigationLauncher. That object is really meant to be a full-featured solution to get nav up and running quickly with minimal customization. So it is not quite as flexible and doesn't allow you to modify your offRoute listeners. This is only possible with NavigationView.
很容易错过，但是有关如何覆盖默认重路由行为的文档实际上是在地图匹配文档中概述的:
It's easy to miss, but the documentation for how to override the default reroute behavior is actually outlined in the Map Matching docs: https://docs.mapbox.com/android/navigation/overview/map-matching/#map-matching-with-mapboxnavigation
考虑到这一点，您似乎在代码中缺少了关键的一步.将 offRouteListener 添加到 navigation 对象时，您需要执行并覆盖 userOffRoute 函数.最终看起来像这样:
With that in mind, it looks like you're missing one crucial step in your code. When you add an offRouteListener to you navigation object, you need to carry through and override the userOffRoute function. Which would end up looking like this:
navigation.addOffRouteListener(new OffRouteListener() {
@Override
public void userOffRoute(Location location) {
Toast.makeText(getApplicationContext(), "Off route detected.........", Toast.LENGTH_SHORT).show();
// Make sure you call for a new DirectionsRoute object
// and end by calling MapboxNavigation#startNavigation on a successful
}
});
