Google Maps Directions intent for bicycle

问题

When using an intent to launch navigation via Google Maps Directions, is there a way to specify you want a route for walking / bicycle?

回答1:

See https://developers.google.com/maps/documentation/directions/

By changing the mode and avoid parameters, the initial request can be modified to return directions for a scenic bicycle journey that avoids major highways.

Travel Modes

When you calculate directions, you may specify the transportation mode to use. By default, directions are calculated as driving directions. The following travel modes are supported:

driving (default) indicates standard driving directions using the road network. walking requests walking directions via pedestrian paths & sidewalks (where available). bicycling requests bicycling directions via bicycle paths & preferred streets (where available). transit requests directions via public transit routes (where available). If you set the mode to transit, you can optionally specify either a departure_time or an arrival_time. If neither time is specified, the departure_time defaults to now (that is, the departure time defaults to the current time). You can also optionally include a transit_mode and/or a transit_routing_preference.

You can use it like this (code snippet from https://stackoverflow.com/a/2663565/1843331)

Intent intent = new Intent(android.content.Intent.ACTION_VIEW, 
    Uri.parse("http://maps.google.com/maps?saddr=20.344,34.34&daddr=20.5666,45.345"));
startActivity(intent);

You can set route using intent like this:

val gmmIntentUri = Uri.parse("google.navigation:q="+destintationLatitude+","+destintationLongitude + "&mode=b")
val mapIntent = Intent(Intent.ACTION_VIEW, gmmIntentUri)
mapIntent.setPackage("com.google.android.apps.maps")
startActivity(mapIntent)

Here, "mode=b" is for bicycle.

We can set driving, walking, and bicycling mode by using:

d for driving
w for walking
b for bicycling

You can find more about intent with google maps here.

Note: If there is no route for the bicycle/car/walk then it will show you "Can't find the way there"
