Question

我正在使用Android并构建一个想要在2点之间导航的应用。我已经有了我的观点。我在谷歌地图上也有它们之间的路线。我只想在它们之间导航。你能帮帮我吗？

Answer 1

考虑您有两个位置来源，目的地，以下代码会将您重定向到谷歌导航，将其作为一种方法，并在您需要时拨打电话！..如果您需要任何其他帮助，请告诉我

Intent intent = new Intent(Intent.ACTION_VIEW, 

Uri.parse("http://ditu.google.cn/maps?f=d&source=s_d" +
                "&saddr="+source.getLatitude()+
                ","+source.getLongitude()+"&daddr="+
                destination.latitude+
                ","+destination.longitude+
                "&hl=zh&t=m&dirflg=d"));  

intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK & Intent.FLAG_ACTIVITY_EXCLUDE_FROM_RECENTS);
intent.setClassName("com.google.android.apps.maps","com.google.android.maps.MapsActivity");
startActivityForResult(intent, 1);

Answer 2

You can try to use Directions API.

The Google Maps Directions API is a service that calculates directions between locations using an HTTP request.

This service is generally designed for calculating directions for static (known in advance) addresses for placement of application content on a map, however this service is not designed to respond in real time to user input.

A Google Maps Directions API request takes the following form:

https://maps.googleapis.com/maps/api/directions/output?parameters

where output may be either of the following values:

json (recommended) indicates output in JavaScript Object Notation (JSON)
xml indicates output as XML

To access the Google Maps Directions API over HTTP, use:

http://maps.googleapis.com/maps/api/directions/output?parameters

HTTPS is recommended for applications that include sensitive user data, such as a user's location, in requests.

You need this parameter in getting the directions:

origin - The address, textual latitude/longitude value, or place ID from which you wish to calculate directions.
destination - The address, textual latitude/longitude value, or place ID to which you wish to calculate directions. The options for the destination parameter are the same as for the origin parameter, described above.

Answer 3

一切正常。

 String uri = "http://maps.google.com/maps?f=d&hl=en&saddr="+startingLocation.latitude+","+startingLocation.longitude+"&daddr="+destinationLocation.latitude+","+destinationLocation.longitude;

 Intent intent = new Intent(android.content.Intent.ACTION_VIEW, Uri.parse(uri));

 startActivity(Intent.createChooser(intent, "Select an application"));
