前段时间公司项目比较忙，百度地图这块拖了好久了，这篇续前面几篇有关百度地图的。好了废话不多说，今天要聊的是有关路径规划的，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。这篇是基于Android百度地图——搜索服务之周边检索，有什么不清楚的请查看前面的几篇博文。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：

[java] view plain copy print ?

//上海市盛夏路益江路的GPS纬度经度值：121.637942,31.205889
MKPlanNodestart=newMKPlanNode();
start.pt=newGeoPoint((int)(31.205889*1E6),(int)(121.637942*1E6));

 // 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：

[java] view plain copy print ?

//上海市陆家嘴的GPS纬度经度值：121.509075,31.243319
MKPlanNodeend=newMKPlanNode();
end.pt=newGeoPoint((int)(31.243319*1E6),(int)(121.509075*1E6));

 // 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

[java] view plain copy print ?

mMKSearch.setDrivingPolicy(MKSearch.ECAR_TIME_FIRST);
mMKSearch.drivingSearch(null,start,null,end);

mMKSearch.setDrivingPolicy(MKSearch.ECAR_TIME_FIRST); mMKSearch.drivingSearch(null, start, null, end);

驾乘检索策略常量：较少费用

[java] view plain copy print ?

mMKSearch.setDrivingPolicy(MKSearch.ECAR_FEE_FIRST);
mMKSearch.drivingSearch(null,start,null,end);

mMKSearch.setDrivingPolicy(MKSearch.ECAR_FEE_FIRST);        mMKSearch.drivingSearch(null, start, null, end);

驾乘检索策略常量：最短距离

[java] view plain copy print ?

mMKSearch.setDrivingPolicy(MKSearch.ECAR_DIS_FIRST);
mMKSearch.drivingSearch(null,start,null,end);

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：

[java] view plain copy print ?

@Override
publicvoidonGetDrivingRouteResult(MKDrivingRouteResultresult,intarg1){
if(result==null)
return;
RouteOverlayrouteOverlay=newRouteOverlay(BaiduMapRouteOverlayActivity.this,mMapView);
routeOverlay.setData(result.getPlan(0).getRoute(0));
mMapView.getOverlays().add(routeOverlay);
mMapView.refresh();//刷新地图
}

    @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：

[java] view plain copy print ?

//步行线路搜索
mMKSearch.walkingSearch(null,start,null,end);

 // 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

[java] view plain copy print ?

@Override
publicvoidonGetWalkingRouteResult(MKWalkingRouteResultresult,intarg1){
//TODOAuto-generatedmethodstub
RouteOverlayrouteOverlay=newRouteOverlay(BaiduMapRouteOverlayActivity.this,mMapView);
routeOverlay.setData(result.getPlan(0).getRoute(0));
mMapView.getOverlays().add(routeOverlay);
mMapView.refresh();//刷新地图
}

 @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。

[java] view plain copy print ?

//公交线路搜索
mMKSearch.transitSearch("上海市",start,end);

      // 公交线路搜索        mMKSearch.transitSearch("上海市", start, end);

获取结果：

[java] view plain copy print ?

@Override
publicvoidonGetTransitRouteResult(MKTransitRouteResultresult,intarg1){
RouteOverlayrouteOverlay=newRouteOverlay(BaiduMapRouteOverlayActivity.this,mMapView);
routeOverlay.setData(result.getPlan(0).getRoute(0));
mMapView.getOverlays().add(routeOverlay);
mMapView.refresh();//刷新地图
}

  @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                             }
