安卓百度地图之步行路径规划

使用的是百度地图的API，地址是：androidsdk | 百度地图API SDK

步骤一：配置build.gradle

dependencies {implementation 'com.baidu.lbsyun:BaiduMapSDK_Location:9.1.8'compile 'com.baidu.lbsyun:BaiduMapSDK_Map:7.4.0'compile 'com.baidu.lbsyun:BaiduMapSDK_Search:7.4.0'
}

步骤二：创建路线规划检索实例

mSearch = RoutePlanSearch.newInstance();

步骤三：创建路线规划检索结果监听器

OnGetRoutePlanResultListener listener = new OnGetRoutePlanResultListener() {@Overridepublic void onGetWalkingRouteResult(WalkingRouteResult walkingRouteResult) {//创建WalkingRouteOverlay实例WalkingRouteOverlay overlay = new WalkingRouteOverlay(mBaiduMap);if (walkingRouteResult.getRouteLines().size() > 0) {//获取路径规划数据,(以返回的第一条数据为例)//为WalkingRouteOverlay实例设置路径数据overlay.setData(walkingRouteResult.getRouteLines().get(0));//在地图上绘制WalkingRouteOverlayoverlay.addToMap();}}......
};
