2点之间的Android谷歌地图路线 [英] android google map route between 2 point
问题描述
我想提请在谷歌地图2点之间的路由与两端点的针痕。在这方面，用户可以选择的车一样行驶路线，通过循环，步行。我要像显示路由信息超前有2英里，从一条街左，对此也估计time.so，我发现很多教程在互联网上。我发现最好的是：
I want to draw route between 2 points in Google map with a pin mark at ends points. in this, user can choose any driving route like by car, by cycle, by walk. I have to show routing information like "2 miles ahead , left from next street" and also estimated time.so regarding this , I found a lot of tutorial on the internet. the best I found is:
的http://$c$c.google.com/p/j2memaprouteprovider/source/browse/#svn/trunk/J2MEMapRouteAndroidEx
，这是非常复杂和缓慢。
which is very complex and slow.
接下来，我发现这一个：
next I found this one:
http://www.anddev.org/google_driving_directions_-_mapview_overlayed-t826.html
这一块是非常相似，我想要的东西，除了一些功能。但它已经过时了。
this one is very similar to what I want, except some feature. but it is outdated.
我还发现，我要使用KML这一点。但我不希望使用它，因为复杂性，所以有必要使用KML？有没有更好的方式来做到这一点？我可以有完整的源$ C $ C作为我被看到code大块混淆。感谢很多提前。
I also found that I have to use KML for this. but i don't want to use it because of complexity so is it necessary to use KML? is there any better way to do this? can i have full source code as I got confused by seeing chunk of code. thanks a lot in advance,.
推荐答案
摇滚，
这个最简单的办法是打开已安装在Android设备谷歌地图应用程序。只是通过源和目标位置的经度和纬度作为参数，调用谷歌地图应用程序如下：
The simplest solution for this is to open "Google Map Application" that is already installed in android device. Just pass the source and target location's latitude and longitude as a parameter and call the google map application as follows:
Intent i = new Intent(Intent.ACTION_VIEW, Uri.parse("http://maps.google.com/maps?saddr="+latitude_source+","+longitude_source+"&daddr="+latitude_dest+","+longitude_dest));
startActivity(i);
使用这种方法，你也可以选择乘汽车一样行驶路线，通过循环，通过由应用程序提供散步等和其他功能。
Using this approach, you can also choose any driving route like by car, by cycle, by walk etc and other functionalities that is provided by application.
