我目前正在开发，将推出一款导航目的的应用程序。我知道，这不是一个官方的API，但它完美的作品，我希望它的方式。

I'm currently developing an application that will launch a navigation intent. I know that this isn't an official API, but it works perfectly the way I want it to.

我允许用户选择驾车，步行，和公交导航到一个位置。直接启动到谷歌地图导航的目的是这样的：

I allow the user to select driving, walking, and bus navigation to a location. The intent to launch directly into Google Maps Navigation looks like this:

google.navigation：LL = +经度和纬度，然后+ ＆功放;模式= 那么你的模式运输。例如，要使用的步行方向在一定区域导航

google.navigation:ll= + a latitude and longitude, then + &mode= then your mode of transportation. For example, to navigate using walking directions to a certain area:

google.navigation：LL =胡说，胡说和放大器;模式= W

驾驶是默认，或＆功放;模式= D ，和骑自行车是＆功放;模式= B ，但我想不通巴士（公交）。

Driving is default, or &mode=d, and biking is &mode=b, but I can't figure out bus (public transit).

有没有人这样做过？

谢谢！

编辑：到目前为止，我发现模式=公共给自行车的方向，模式=中天给驾驶，无奈的是，模式=总线也返回自行车的方向。

So far, I've found that mode=public gives bike directions, mode=transit gives driving, frustratingly, mode=bus also returns bike directions.

更多：模式=火车也给驾驶......我们有了一个方法来做到这一点...

More: mode=train also gives driving... There's GOT to be a way to do this...

另一个编辑：我意识到刚才我是pretty的确保它不存在，因为有方面，我意识到，我应该将推出与谷歌地图的意图试验后公交搜索，但没有人知道如何做到这一点？

Another I realized just now that I'm pretty sure that it doesn't exist, because after experimenting with terms I realized that I should instead launch a Google Maps intent with a bus search, but does anyone know how to do this?

推荐答案

一堆猜测和狩猎左右后，我决定，这是不可能直接启动到公交车的导航，因为这将涉及选择公交车的人骑，这是没有意义的。

After a bunch of guessing and hunting around, I have decided that it is impossible to launch directly to bus navigation, because that would involve CHOOSING a bus for the person to ride, which wouldn't make sense.

相反，你可以将它们发射到谷歌地图搜索，像这样的目标，谢谢这个答案以一个类似的问题：

Instead, you can launch them to a Google Maps search to the destination like so, thank you to this answer to a similar question:

http://maps.google.com/maps?daddr=lat,long&dirflg=r

随着＆放大器; dirflag 指定公共交通。 （为什么R我不知道......）

With the &dirflag specifying public transit. (Why the "r" I have no idea...)
