1. 设置路线规划监听
mSearch.setOnGetRoutePlanResultListener(getRoutePlanListener);//设置路线规划监听
2.初始化路线监听器
/*路线规划监听器*/private OnGetRoutePlanResultListener getRoutePlanListener = new OnGetRoutePlanResultListener() {@Overridepublic void onGetWalkingRouteResult(WalkingRouteResult walkingRouteResult) {}@Overridepublic void onGetTransitRouteResult(TransitRouteResult transitRouteResult) {}@Overridepublic void onGetMassTransitRouteResult(MassTransitRouteResult massTransitRouteResult) {}public void onGetDrivingRouteResult(DrivingRouteResult result) {//获取驾车线路规划结果DialogUtil.closeDialog();if (result.error == SearchResult.ERRORNO.NO_ERROR) {// mroute = result.getRouteLines().get(0); baiduMap.clear();DrivingRouteOverlay overlay = new MyDrivingRouteOverlay(baiduMap);overlay.setData(result.getRouteLines().get(0));overlay.addToMap();overlay.zoomToSpan();} else {DialogUtil.showShortToast(ChooseGasStationActivity.this, "请输入正确的地址！");}}@Overridepublic void onGetIndoorRouteResult(IndoorRouteResult indoorRouteResult) {}@Overridepublic void onGetBikingRouteResult(BikingRouteResult bikingRouteResult) {}};
3.DrivingRouteOverlay是百度demo中的一个类，找到后放到 项目中，可以继承这个类，也可以直接在此类中修改代码。

4.ok
