Question

如何以方向单位公里/分钟显示mapbox的navigationview而不是英里/英尺

 String awsPoolId = null;
        boolean simulateRoute = false;

        Log.e("=origin==", "" + origin);
        Log.e("=desti==", "" + destination);

        // Call this method with Context from within an Activity
        NavigationLauncher.startNavigation(GotoPickup.this, origin, destination, awsPoolId, simulateRoute);

Answer 1

您必须设置所需的类型 (METRIC)。我从 Mapbox 计算路线(注意语音指令)并将其传递给 NavigationLauncher:

NavigationRoute.builder()
.voiceUnits(DirectionsCriteria.METRIC)
...
.build()
.getRoute(new Callback<DirectionsResponse>() {
        // Checkout mapbox tutorials for this part
        DirectionsRoute directionsRoute = ...

        NavigationLauncherOptions options = NavigationLauncherOptions.builder()
            .directionsRoute(directionsRoute)
            .unitType(NavigationUnitType.TYPE_METRIC)
            .build();

        NavigationLauncher.startNavigation(MyActivity.this, options);
    }
});

与 com.mapbox.mapboxsdk:mapbox-android-navigation-ui:0.13.0 配合良好
