可以通过RasterMap的getDirection()方法来查询路径，和查询地址类似，路径查询的结果也是通过回调函数的方式来通知应用程序的，下面的例子返回南京到北京的路径。返回结果存放在MapDirection中，MapDirection包含了路径的详细信息，包括路径的每个步骤，长度，时间，方向等。

Java代码：

packageeoe.demo;

importcom.mapdigit.gis.MapDirection;

importcom.mapdigit.gis.MapPoint;

importcom.mapdigit.gis.geometry.GeoLatLng;

importcom.mapdigit.gis.service.IRoutingListener;

importcom.pstreets.gisengine.R;

importcom.pstreets.gisengine.SharedMapInstance;

importandroid.app.Activity;

importandroid.os.Bundle;

importandroid.view.Menu;

importandroid.view.MenuInflater;

importandroid.view.MenuItem;

publicclassMapRoutingextendsActivityimplementsIRoutingListener{

@Override

publicvoidonCreate(BundlesavedInstanceState){

super.onCreate(savedInstanceState);

setContentView(yout.main);

}

@Override

publicvoidonStart(){

super.onStart();

GeoLatLngcenter=newGeoLatLng(32.0616667,118.7777778);

SharedMapInstance.map.setCenter(center,15,

com.mapdigit.gis.raster.MapType.MICROSOFTCHINA);

SharedMapInstance.map.setRoutingListener(this);

}

@Override

publicbooleanonCreateOptionsMenu(Menumenu){

MenuInflaterinflater=getMenuInflater();

inflater.inflate(R.menu.maprouting_menu,menu);

returntrue;

}

@Override

publicbooleanonOptionsItemSelected(MenuItemitem){

//Handleitemselection

switch(item.getItemId()){

caseR.id.getdirection:

Stringname1="南京";

Stringname2="北京";

SharedMapInstance.map.getDirections("from:"+name1+"to:"

+name2);

returntrue;

default:

returnsuper.onOptionsItemSelected(item);

}

}

@Override

publicvoiddone(Stringquery,MapDirectionresult){

if(result!=null){

SharedMapInstance.map.setMapDirection(result);

SharedMapInstance.map.resize(result.getBound());

SharedMapInstance.map.zoomOut();

SharedMapInstance.map.zoomOut();

}

}

@Override

publicvoidreadProgress(intbytes,inttotal){

}

}
