问题描述

我拍图我的校园和需要帮助。谁能告诉我怎么找到方向添加到特定的GeoPoint？我想用户点击地图图标在地图上，把他们那个地方的描述页面，然后可以选择路径方向看似简单，但我很新的Java和Android系统。

I'm making a map for my campus and need help. Can anyone tell me how to add driving directions to a specific geopoint? I would like the user to click on a map icon on the map, bring them to a description page of that place, and then have the option to "route directions" Seems simple but I'm very new to Java and Android.

推荐答案

最简单的办法是链接到谷歌地图应用程序。下面的网址会处理的。

The easiest option would be to link out to the Google Maps application. The URL below will handle that.

Uri uri= Uri.parse( "http://maps.google.com/maps?saddr=" + startLocation.getLatitude() + "," + startLocation.getLongitude() + "&daddr="+mapItem.lat + "," + mapItem.lon );
Intent intent = new Intent(Intent.ACTION_VIEW, uri);
mActivity.startActivity(intent);

另外，请查阅本页面中的所有地图网址的选项：
