算路、选路及上传路线，为了保持司机端和客户端路线一致，该部分接口由司乘同显导航SDK提供。

若乘客端业务需要实现乘客端选择算路路线，乘客端需要集成司乘同显导航SDK。

示例代码如下：

// 设置起点位置
BNRoutePlanNode sNode = new BNRoutePlanNode(116.43370,39.92144, "起点", null, BNRoutePlanNode.CoordinateType.GCJ02);
// 设置终点位置
BNRoutePlanNode eNode = new BNRoutePlanNode( 116.30654,40.04162, "终点", null, BNRoutePlanNode.CoordinateType.GCJ02);
List<BNRoutePlanNode> list = new ArrayList<>();
list.add(sNode);
list.add(eNode);
BaiduNaviManagerFactory.getRoutePlanManager().routeplan(
        list,
        IBNRoutePlanManager.RoutePlanPreference.ROUTE_PLAN_PREFERENCE_DEFAULT,
        null,
        new Handler(Looper.getMainLooper()) {
            @Override
            public void handleMessage(Message msg) {
                switch (msg.what) {
                    case IBNRoutePlanManager.MSG_NAVI_ROUTE_PLAN_START:
                        Toast.makeText(getApplicationContext(), "算路开始", Toast.LENGTH_SHORT).show();
                        break;
                    case IBNRoutePlanManager.MSG_NAVI_ROUTE_PLAN_SUCCESS:
                        Toast.makeText(getApplicationContext(), "算路成功", Toast.LENGTH_SHORT).show();
// 通过handler移除算路请求
    BaiduNaviManagerFactory.getRoutePlanManager().removeRequestByHandler(this);
                        break;
                    case IBNRoutePlanManager.MSG_NAVI_ROUTE_PLAN_FAILED:
                        Toast.makeText(getApplicationContext(), "算路失败", Toast.LENGTH_SHORT).show();
                        // 通过handler移除算路请求BaiduNaviManagerFactory.getRoutePlanManager().removeRequestByHandler(this);
                        break;
                    default:
                        // nothing
                        break;
                }
            }
        });
       

发起算路后，在算路成功的回调里，能够获取3条路线信息，每一条路线信息包含路线长度、路线驾车时间、路线红绿灯个数等信息。以下介绍重要方法调用，完整代码请参考司机端demo中DemoRouteResultFragment中的使用。

示例代码如下：

Bundle bundle = (Bundle) msg.obj;
mRoutePlanItems = bundle.getParcelableArrayList(BNaviCommonParams.BNRouteInfoKey.INFO_TAB);
if (mRoutePlanItems != null) {
    if (mRoutePlanItems.size() > 0 && mRoutePlanItems.get(0) != null) {

        String pusLabelName = mRoutePlanItems.get(0).getPusLabelName();
        // 路线驾车时间
        int time = (int) (mRoutePlanItems.get(0).getPassTime() / 60);
        // 路线长度
        int lenth = (int) (mRoutePlanItems.get(0).getLength() / 1000.0f);
    }

    if (mRoutePlanItems.size() > 1 && mRoutePlanItems.get(1) != null) {
        String pusLabelName = mRoutePlanItems.get(0).getPusLabelName();
        // 路线驾车时间
        int time = (int) (mRoutePlanItems.get(0).getPassTime() / 60);
        // 路线长度
        int lenth = (int) (mRoutePlanItems.get(0).getLength() / 1000.0f);                       }

    if (mRoutePlanItems.size() > 2 && mRoutePlanItems.get(2) != null) {
        String pusLabelName = mRoutePlanItems.get(0).getPusLabelName();
        // 路线驾车时间
        int time = (int) (mRoutePlanItems.get(0).getPassTime() / 60);
        // 路线长度
        int lenth = (int) (mRoutePlanItems.get(0).getLength() / 1000.0f);
    }
}

根据回调的3条路线数据中的路线id指定要选择的路线

示例代码：

// 根据路线ID选择路线
BaiduNaviManagerFactory.getRouteResultManager().selectRoute(mRoutePlanItems.get(0).getRoutId());

确定使用选中的路线并上传到服务端，用于司机端发起算路导航。

示例代码：

BNOrderInfo info = new BNOrderInfo();
info.startNode = new BNRoutePlanNode(116.45932,39.91885, "起点", null, BNRoutePlanNode.CoordinateType.GCJ02);
info.pickupNode = ((SyncCustomDemo) getActivity()).mSNode;
info.endNode = ((SyncCustomDemo) getActivity()).mENode;
info.orderId = mOrderId;
info.driverId = "3333";
info.companyServerId = "88888888";
info.orderState = BNOrderState.SEND_PASSENGER;
BaiduNaviManagerFactory.getRouteResultManager().upLoadRouteInfo(
info, new IBNRequestListener() {
    @Override
    public void onRequestResult(final int i, String s, final String s1) {
        if (getActivity() == null) {
            return;
        }
        getActivity().runOnUiThread(new Runnable() {
            @Override
            public void run() {
                if (i != 200) {
                    Toast.makeText(getActivity(), "上传失败", Toast.LENGTH_LONG).show();
                    return;
                }
                try {
                    JSONObject object = new JSONObject(s1);
                    if (object.getInt("status") != 0) {
                        Toast.makeText(getActivity(), "上传失败", Toast.LENGTH_LONG).show();
                    }else {
                        Toast.makeText(getActivity(), "上传成功", Toast.LENGTH_LONG).show();
                    }
                } catch (JSONException e) {
                    e.printStackTrace();
                }
            }
        });
    }
});

选路页面的生命周期管理

示例代码：

@Override
    public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container,
    @Nullable Bundle savedInstanceState) {
        BaiduNaviManagerFactory.getRouteResultManager().onCreate(getActivity());
        View view = inflater.inflate(R.layout.fragment_route_result, container, false);
        mLayout = view.findViewById(R.id.container);
        BaiduNaviManagerFactory.getMapManager().attach(mLayout);

        return view;
    }
    @Override
    public void onPause() {
        super.onPause();
        BaiduNaviManagerFactory.getMapManager().onPause();
        BaiduNaviManagerFactory.getRouteResultManager().onPause();
    }

    @Override
    public void onResume() {
        super.onResume();
        BaiduNaviManagerFactory.getMapManager().onResume();
        BaiduNaviManagerFactory.getRouteResultManager().onResume();
    }

    @Override
    public void onDestroy() {
        super.onDestroy();
        BaiduNaviManagerFactory.getMapManager().detach(mLayout);
        BaiduNaviManagerFactory.getRouteResultManager().onDestroy();
    }
