RoutePreviewNavigationTemplate

public final class RoutePreviewNavigationTemplate
extends Object implements Template

A template that supports showing a list of routes alongside a custom drawn map.

The list must have its ItemList.OnSelectedListener set, and the template must have its navigate action set (see RoutePreviewNavigationTemplate.Builder.setNavigateAction(Action)). These are used in conjunction to inform the app that:

1. A route has been selected. The app should also highlight the route on the map surface.
2. A navigate action has been triggered. The app should begin navigation using the selected route.

The template itself does not expose a drawing surface. In order to draw on the canvas, use AppManager.setSurfaceCallback(SurfaceCallback).

Template Restrictions

• The template title has not changed, and
• The previous template is in a loading state (see RoutePreviewNavigationTemplate.Builder.setLoading(boolean), or the number of rows and the string contents (title, texts, not counting spans) of each row between the previous and new ItemLists have not changed.

Note that specifically, this means the app can't use this template to continuously refresh the routes as the car moves without hitting the template limit.

In order to use this template your car app MUST declare that it uses the androidx.car.app.NAVIGATION_TEMPLATES permission in the manifest.
