Automobile Routing
Design a travel plan tailored to the user based on the departure location, destination, and set path strategy. At the same time, combined with real-time traffic, it helps users to bypass congested sections and provide a more intimate and more user-friendly driving route. The sample code is as follows:
// Set the starting point and end point coordinates
GeoPoint startGeoPoint = new GeoPoint(116.39750, 39.90850); //Tiananmen
GeoPoint endGeoPoint = new GeoPoint(116.43423, 39.93766); //Dongzhimen Street
RoutePlan routePlan = new RoutePlan();
// Set the listener
routePlan.setListener(new RoutePlan.Listener() {
@Override
public void onSuccess(final RouteResult result) {
//search successful
}
@Override
public void onFail(final APIStatus status) {
//Query failed
}
});
// Set the request parameters
RoutePlan.Query query = RoutePlan.Query.newQuery(startGeoPoint, endGeoPoint, RoutePlanType.CAR);
// Set the route mode
query.setPolicy(0);
// Set to return a route, the value range is 1 <= num <= 3;
query.setNum(1);
routePlan.setQuery(query);
//Initiate a request
routePlan.plan();
RoutePlan.Query Description:
1. Obtain an instance by using the newQuery (GeoPoint startPoint, GeoPoint endPoint, int queryType) method in RoutePlan.Query;
2. startPoint starting point GeoPoint coordinates;
3. endPoint endpoint GeoPoint coordinates;
4. queryType calculation type, driving calculation type is RoutePlanType.CAR;
5. setNum(int num) sets the number of rows returned by the algorithm, num takes the range 1 <= num <= 3;
6. The setPolicy(int policy) method is used to set the conditions for the calculation. The value of the policy is as follows:
| value | meaning |
|---|---|
0 | Default (road condition + time + mileage comprehensive consideration) |
1 | Dodge congestion |
2 | Do not take high speed |
3 | High Speed Priority |
4 | Avoid Charge |
5 | Dod to avoid congestion & not to go high speed |
6 | Dodge congestion & high speed priority |
7 | Dodge congestion & avoid charges |
8 | Dod to avoid congestion & avoid high speed & avoid charges |
0 | Do not go high speed & avoid charges |
Note: The result return interface is an asynchronous thread interface. If the Android project needs to operate the control in the return, it must switch to the Main main thread.
