有关路径规划的，如何使用百度地图搜索驾车、步行和公交路线并标注在地图上。路径规划：从那里到那里的线路规划，比如：从上海市盛夏路益江路到陆家嘴的驾车、步行和公交路线。
一、从那里到那里：
1、起始地点：
// 上海市盛夏路益江路的GPS纬度经度值：121.637942,31.205889 MKPlanNode start = new MKPlanNode(); start.pt = new GeoPoint((int) (31.205889 * 1E6), (int) (121.637942 * 1E6));
2、目的地点：
// 上海市陆家嘴的GPS纬度经度值： 121.509075,31.243319 MKPlanNode end = new MKPlanNode(); end.pt = new GeoPoint( (int) (31.243319 * 1E6), (int) (121.509075 * 1E6));
注：获取地点的GPS值可以到http://api.map.baidu.com/lbsapi/getpoint/index.html查询，要注意拿到的值的顺序，获取到的值是经纬度（也就是说第一个表示的是经度值，第二个表示的是纬度值）。而我们在地图上查找或标注时使用的顺序是GPS纬度经度值，因此记得调整顺序，不然在百度地图上就显示不出来。
二、如何到达，怎样到达：
1、驾车线路：
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 } 四、完整代码：
