百度地图BaiduMapsApiASDemo中驾车路线RoutePlanDemo的个人理解

驾车路线规划

1 创建驾车路线检索实例

RoutePlanSearch mSearch = RoutePlanSearch.newInstance();

2 创建驾车路线规划检索监听者

 OnGetRoutePlanResultListener listener = new OnGetRoutePlanResultListener() {
            @Override
            public void onGetWalkingRouteResult(WalkingRouteResult walkingRouteResult) {

            }

            @Override
            public void onGetTransitRouteResult(TransitRouteResult transitRouteResult) {

            }

            @Override
            public void onGetMassTransitRouteResult(MassTransitRouteResult massTransitRouteResult) {

            }

            @Override
            public void onGetDrivingRouteResult(DrivingRouteResult drivingRouteResult) {

            }

            @Override
            public void onGetIndoorRouteResult(IndoorRouteResult indoorRouteResult) {

            }

            @Override
            public void onGetBikingRouteResult(BikingRouteResult bikingRouteResult) {

            }
        }；

3 设置驾车路线检索监听者

 mSearch.setOnGetRoutePlanResultListener(this);

4 准备检索起终点信息

// 处理搜索按钮响应
// 设置起终点信息，对于tranist search 来说，城市名无意义

        PlanNode stNode = PlanNode.withCityNameAndPlaceName("北京", startNodeStr);
        PlanNode enNode = PlanNode.withCityNameAndPlaceName("北京", endNodeStr);

startNodeStr endNodeStr 为用户手动输入文本框的信息

PlanNode 实现Parcelable接口将用户输入的信息规范化

5 调用对应的方法发起路线规划检索（一般为点击事件）

    <!--跨城公交-->
    mSearch.masstransitSearch(new             MassTransitRoutePlanOption().from(stMassNode).to(enMassNode));
    nowSearchType = 0;

<!--驾车-->
    mSearch.drivingSearch((new DrivingRoutePlanOption())
            .from(stNode).to(enNode));
    nowSearchType = 1;

释放检索实例

    @Override
    protected void onDestroy() {
        if (mSearch != null) {
            mSearch.destroy();
        }
        mMapView.onDestroy();
        super.onDestroy();
    }

其中各种画图类使用 的时候直接复制

<!--例子为驾车路线的画图类-->
 private class MyDrivingRouteOverlay extends DrivingRouteOverlay {

        public MyDrivingRouteOverlay(BaiduMap baiduMap) {
            super(baiduMap);
        }

        @Override
        public BitmapDescriptor getStartMarker() {
            if (useDefaultIcon) {
                return BitmapDescriptorFactory.fromResource(R.drawable.icon_st);
            }
            return null;
        }

        @Override
        public BitmapDescriptor getTerminalMarker() {
            if (useDefaultIcon) {
                return BitmapDescriptorFactory.fromResource(R.drawable.icon_en);
            }
            return null;
        }
    }
