推荐答案
首先，您应该了解Google Maps Platform服务条款对创建实时导航或逐行导航有某些限制.基本上，您不允许在您的应用程序中创建此类功能.
First of all you should be aware that Google Maps Platform Terms of Service have certain restrictions regarding creation of real-time or turn-by-turn navigation. Basically, you are not allowed to create such functionality in you app.
请参阅ToS的第3.2.4节禁止滥用服务的限制".在(c)段中，您将找到以下内容
Have a look at section 3.2.4 'Restrictions Against Misusing the Services' of ToS. In paragraph (c) you will find the following
不得重新创建Google产品或功能.客户不得使用服务来创建具有与其他Google产品或功能基本相似或具有相同功能的产品或服务.服务...
No Re-Creating Google Products or Features. Customer will not use the Services to create a product or service with features that are substantially similar to or that re-create the features of another Google product or service...
例如，客户不会:...
For example, Customer will not: ...
(iv)结合来自Directions API，Geolocation API和Android版Maps SDK的数据，以创建与Google Maps for Android移动应用程序所提供功能基本相似的实时导航功能.
(iv) combine data from the Directions API, Geolocation API, and Maps SDK for Android to create real-time navigation functionality substantially similar to the functionality provided by the Google Maps for Android mobile app.

这意味着，根据服务条款，唯一允许的选项是将用户重定向到Google Maps应用，以便他们可以使用导航模式.
That means that the only allowed option according to the ToS is redirect your users to Google Maps app where they can use navigation mode.
您应该创建一个在导航模式下打开Google Maps本机应用程序的意图.有一个Google Maps URL，它可以构造一个通用的跨平台URL，以从您的应用程序启动Google Maps Intent.您可以按照以下文档打开本机应用程序的导航模式:
You should create an intent that opens the Google Maps native app in navigation mode. There is a Google Maps URLs that allows to construct a universal, cross-platform URL to launch Google Maps intents from your application. You can open navigation mode of native app following this documentation:
https://developers.google.com/maps/documentation /urls/guide#directions-action
代码快照可能是
String url = "https://www.google.com/maps/dir/?api=1&destination=Madrid,Spain&origin=Barcelona,Spain&waypoints=Zaragoza|Huesca&travelmode=driving&dir_action=navigate";
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
startActivity(intent);
