Google Navigation (Android 1.6) 意图回调 [英] Google Navigation (Android 1.6) intent callback

问题描述

我正在使用 Intent 启动 Google 导航:

I'm using intents to launch Google Navigation:

Intent i = new Intent(Intent.ACTION_VIEW, Uri.parse("google.navigation:q=" + location)); 
startActivity(i);

location 是一个带有 GPS 坐标的字符串.

location is a string with GPS coordinates.

Google Navigation 会很好地弹出并绘制路线图.当用户到达目的地时，他们可以返回某种类型的回调吗?有什么方法可以实现 startActivityForResult()?

Google Navigation pops up nicely and plots the route. Can they return some type of callback when the user has reached their destination? Any way of implementing startActivityForResult()?

如果不是，我最好的选择是什么?我一直在考虑在后台运行一项服务，该服务会密切关注位置并结束 Google 导航，并在 GPS 记录它在目的地附近时返回我的应用程序(因为我知道纬度/经度).

If not, what would be my best bet? I've been considering running a service in the background that keeps tabs on the location and ending Google Navigation and returning to my app when the GPS registers that it's near the destination (because I know the latitude/longitude).

谢谢大家

推荐答案

我想发布我是如何设法让它工作的.我没有使用活动回调，但我正在启动一个带有 LocationManager 的服务.当用户接近目的地坐标时，我只是终止 Google Navigation 并重新开始我的活动.

I wanted to post how I managed to get this to work. I'm not using activity callbacks, but I am starting a service with a LocationManager hanging out in it. When the user gets close to the destination coordinates, I just terminate Google Navigation and start my activity back up.
