在项目中用到地图的地方往往会有导航功能，那么这一节将介绍一下使用高德地图来实现驾车路线规划的功能。

首先来两张示例图供参考：

                                        

接下来还是直接上代码更直观

建立DriverRouteActivity.java主程序类

出行路线规划还有公交路线规划、步行路线规划、骑行路线规划，实现这些功能都是要实现RouteSearch.OnRouteSearchListener接口，在对应的回调方法里实现功能就行了

    /**
     * 公交路线搜索结果方法回调
     */
    @Override
    public void onBusRouteSearched(BusRouteResult busRouteResult, int i) {
        dissmissProgressDialog();

		if (errorCode == AMapException.CODE_AMAP_SUCCESS) {
