java - Mapbox导航useroffroute功能覆盖不起作用
问题描述
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 useroffroute 功能没有被触发。

我希望我覆盖的函数 useroffroute 被触发。但是没有触发发生，因为当用户离开路由时，我无法看到 toast 消息和文件创建。
解决方案
所以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齐全的解决方案，可以通过最少的自定义快速启动和运行导航。所以它不是那么灵活，并且不允许你修改你的offRoute听众。这只有在NavigationView.
很容易错过，但地图匹配文档中实际上概述了如何覆盖默认重新路由行为的文档：https ://docs.mapbox.com/android/navigation/overview/map-matching/#map-matching-带地图框导航
考虑到这一点，您的代码中似乎缺少了一个关键步骤。当您offRouteListener向对象添加一个navigation对象时，您需要执行并覆盖该userOffRoute功能。最终看起来像这样：
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
}
});
