准备工作： 在百度地图上下载依赖，配置key。创建一个demo项目，可显示百度地图的添加按钮，点击按钮，开始导航发起算路我用的是routePlanWithRouteNode这个方法，官网中routePlanWithParams这个方法，我调着闪退，目前不清楚原因这个版本的需要设置隐私政策 SDKInitializer.setAgreePrivacy(this,true);
// 在使用 SDK 各组间之前初始化 context 信息，传入 ApplicationContextSDKInitializer.setAgreePrivacy(this,true);// 默认本地个性化地图初始化方法SDKInitializer.initialize(Utils.getContext());//自4.3.0起，百度地图SDK所有接口均支持百度坐标和国测局坐标，用此方法设置您使用的坐标类型.//包括BD09LL和GCJ02两种坐标，默认是BD09LL坐标。SDKInitializer.setCoordType(CoordType.BD09LL);
此时地图会显示比例尺，显示纯绿色 如果用了LocationClient，也给他设置一下
LocationClient.setAgreePrivacy(true);
在mainAcitivity中，添加如下代码
private WalkNavigateHelper helper = null;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);initPermissions(); // 初始化权限setContentView(R.layout.activity_main); // 填充视图initView(); // 初始化地图// 点击按钮开始导航ImageButton imageButton = findViewById(R.id.nav_btn);imageButton.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View view) {// 初始化步行导航 startBikeNavi();}});}// 初始化权限private void initPermissions() {if (Build.VERSION.SDK_INT >= 23) {ArrayList<String> permissionsList = new ArrayList<>();String[] permissions = {Manifest.permission.ACCESS_NETWORK_STATE,Manifest.permission.INTERNET,Manifest.permission.ACCESS_COARSE_LOCATION,Manifest.permission.ACCESS_FINE_LOCATION,Manifest.permission.WRITE_EXTERNAL_STORAGE,};for (String perm : permissions) {if (PackageManager.PERMISSION_GRANTED != checkSelfPermission(perm)) {permissionsList.add(perm);// 进入到这里代表没有权限.}if (!permissionsList.isEmpty()) {String[] strings = new String[permissionsList.size()];requestPermissions(permissionsList.toArray(strings), 0);}}}}/*** @Description: 引擎初始化* @Author: LY*/private void startBikeNavi() {Log.d("=========", "startBikeNavi");try {helper = WalkNavigateHelper.getInstance();helper.initNaviEngine(this, new IWEngineInitListener() {@Overridepublic void engineInitSuccess() {Log.d("=========", "BikeNavi engineInitSuccess引擎初始化成功");startWebNavi();}@Overridepublic void engineInitFail() {Log.d("=========", "BikeNavi engineInitFail");BikeNavigateHelper.getInstance().unInitNaviEngine();}});} catch (Exception e) {Log.d("=========", "startBikeNavi Exception");e.printStackTrace();}}/*** @Description: 启动百度地图导航(Web)* @Author: LY*/private void startWebNavi() {//起终点位置LatLng walkStartNode = new LatLng(40.047416, 116.312143);LatLng walkEndNode = new LatLng(40.048424, 116.313513);WalkRouteNodeInfo startNode = new WalkRouteNodeInfo();startNode.setLocation(walkStartNode);WalkRouteNodeInfo endNode = new WalkRouteNodeInfo();endNode.setLocation(walkEndNode);// 官网//构造WalkNaviLaunchParamWalkNaviLaunchParam walkParam = new WalkNaviLaunchParam().startNodeInfo(startNode).endNodeInfo(endNode);//获取WalkNavigateHelper实例 //发起算路helper.routePlanWithRouteNode(walkParam, new IWRoutePlanListener() {@Overridepublic void onRoutePlanStart() {Log.d("=======", "WalkNavi onRoutePlanStart开始步行导航");}@Overridepublic void onRoutePlanSuccess() {Log.d("========", "onRoutePlanSuccess算路成功");Intent intent = new Intent();intent.setClass(getContext(), WNaviGuideActivity.class);startActivity(intent);}@Overridepublic void onRoutePlanFail(WalkRoutePlanError error) {Log.d("Walk", "WalkNavi onRoutePlanFail");}});}
创建WNaviGuideActivity类，改包名，无脑粘

在AndroidManifest中声明WNaviGuideActivity
<activity android:name=".WNaviGuideActivity"></activity>
