android接入高德路线规划，不会显示路线拥堵情况。
//初始化路线规划，监听回调数据
try {
if (routeSearchV2 == null) {
routeSearchV2 = new RouteSearchV2(getActivity());
}
routeSearchV2.setRouteSearchListener(this);
} catch (AMapException e) {
e.printStackTrace();
}

    RouteSearchV2.FromAndTo fromAndTo1 = new RouteSearchV2.FromAndTo(startLatLon, latLonPoint);

    RouteSearchV2.DriveRouteQuery query1 = new RouteSearchV2.DriveRouteQuery(fromAndTo1, RouteSearchV2.DrivingStrategy.DEFAULT, null,
            null, "");// 第一个参数表示路径规划的起点和终点，第二个参数表示驾车模式，第三个参数表示途经点，第四个参数表示避让区域，第五个参数表示避让道路

	主要就是这个方法，官方API没有更新，找了两天才解决，还是另一个大佬给解决的。心塞
    //显示扩展字段  
    query1.setShowFields(RouteSearchV2.ShowFields.POLINE | RouteSearchV2.ShowFields.CITIES |
            RouteSearchV2.ShowFields.COST | RouteSearchV2.ShowFields.NAVI | RouteSearchV2.ShowFields.TMCS);
    // 异步路径规划驾车模式查询
    routeSearchV2.calculateDriveRouteAsyn(query1);

// 在回调中这么写
@Override
public void onDriveRouteSearched(DriveRouteResultV2 driveRouteResultV2, int errorCode) {
if (drivingRouteOverlay != null)
drivingRouteOverlay.removeFromMap();

    if (errorCode == AMapException.CODE_AMAP_SUCCESS) {
        if (driveRouteResultV2 != null && driveRouteResultV2.getPaths() != null) {
            if (driveRouteResultV2.getPaths().size() > 0) {
                mDriveRouteResultV2 = driveRouteResultV2;
                final DrivePathV2 drivePath = driveRouteResultV2.getPaths()
                        .get(0);
                drivingRouteOverlay = new DrivingRouteOverlay(
                        getContext(), aMap, drivePath,
                        mDriveRouteResultV2.getStartPos(),
                        mDriveRouteResultV2.getTargetPos(), null);

                drivingRouteOverlay.setRouteWidth(20);
                drivingRouteOverlay.setNodeIconVisibility(false);//设置节点marker是否显示
                drivingRouteOverlay.setIsColorfulline(true);//是否用颜色展示交通拥堵情况，默认true
                drivingRouteOverlay.addToMap();
                drivingRouteOverlay.zoomToSpan();
            }
        }
    }
}
