驾乘检索策略常量：时间优先


mMKSearch.setDrivingPolicy(MKSearch.ECAR_TIME_FIRST);

        mMKSearch.drivingSearch(null, start, null, end);

驾乘检索策略常量：较少费用


mMKSearch.setDrivingPolicy(MKSearch.ECAR_FEE_FIRST);

        mMKSearch.drivingSearch(null, start, null, end);

驾乘检索策略常量：最短距离


mMKSearch.setDrivingPolicy(MKSearch.ECAR_DIS_FIRST);

        mMKSearch.drivingSearch(null, start, null, end);

获取结果并展示时，需要实现MKSearchListener接口中的onGetDrivingRouteResult方法：


    @Override

            public void onGetDrivingRouteResult(MKDrivingRouteResult result, int arg1) {

                if (result == null)

                    return;

                

                RouteOverlay routeOverlay = new RouteOverlay(BaiduMapRouteOverlayActivity.this, mMapView);   

                

                routeOverlay.setData(result.getPlan(0).getRoute(0)); 

                mMapView.getOverlays().add(routeOverlay);

                mMapView.refresh();//刷新地图

                

            }

2、步行线路：


 // 步行线路搜索

        mMKSearch.walkingSearch(null, start, null, end);

获取结果并展示时，需要实现MKSearchListener接口中的onGetWalkingRouteResult方法


 @Override

            public void onGetWalkingRouteResult(MKWalkingRouteResult result, int arg1) {

                // TODO Auto-generated method stub

            	 RouteOverlay routeOverlay = new RouteOverlay(BaiduMapRouteOverlayActivity.this, mMapView);   

                 routeOverlay.setData(result.getPlan(0).getRoute(0)); 

                 mMapView.getOverlays().add(routeOverlay);

                 mMapView.refresh();//刷新地图

            }

3、公交线路：

公交线路搜索的方法为transitSearch(String city, MKPlanNode start, MKPlanNode end)，city：为待查公交线路所在城市，start和end分别是起点和终点；获取结果的方法改为重写onGetTransitRouteResult方法。


      // 公交线路搜索

        mMKSearch.transitSearch("上海市", start, end);

获取结果：


  @Override

            public void onGetTransitRouteResult(MKTransitRouteResult result, int arg1) {

            	 RouteOverlay routeOverlay = new RouteOverlay(BaiduMapRouteOverlayActivity.this, mMapView);   

                 routeOverlay.setData(result.getPlan(0).getRoute(0)); 

                 mMapView.getOverlays().add(routeOverlay);

                 mMapView.refresh();//刷新地图

                 

            }
