如何使用 Google Maps API v2 取得行車路線？

<code class="java">import akexorcist.googledirection.DirectionCallback;

import akexorcist.googledirection.GoogleDirection;

import akexorcist.googledirection.constant.TransportMode;

import akexorcist.googledirection.model.Direction;

// Initialize GoogleDirection

GoogleDirection googleDirection = new GoogleDirection(apiKey);

// Set the departure and arrival locations

LatLng origin = new LatLng(12.917745600000000000, 77.623788300000000000);

LatLng destination = new LatLng(12.842056800000000000, 7.663096499999940000);

// Request directions

googleDirection.withTransportMode(TransportMode.DRIVING)

        .withOrigin(origin)

        .withDestination(destination)

        .execute(new DirectionCallback() {

            @Override

            public void onDirectionSuccess(Direction direction, String rawBody) {

                // Process and display driving directions

            }

            @Override

            public void onDirectionFailure(Throwable t) {

                // Handle direction retrieval error

            }

        });</code>
