百度地图总结第四篇之路线规划功能
线路规划：
今天总结的有四种路线方案，分别是驾车、公交(通从)、步行(同城)、骑行。(自3.7.0起，新增骑行线路规划功能)
好了下面我们来看下吧，这里的代码有点多，我在本篇结束后，会给出github地址，以便参考(这里基本也是demo里面的代码)。
公交线路规化：
第一步，创建公交线路规划检索实例；
mSearch = RoutePlanSearch.newInstance();
第二步，创建公交线路规划检索监听者；
OnGetRoutePlanResultListener listener = new OnGetRoutePlanResultListener() {
public void onGetWalkingRouteResult(WalkingRouteResult result) {
//
}
public void onGetTransitRouteResult(TransitRouteResult result) {
if (result == null || result.error != SearchResult.ERRORNO.NO_ERROR) {
Toast.makeText(RoutePlanDemo.this, "抱歉，未找到结果", Toast.LENGTH_SHORT).show();
}
if (result.error == SearchResult.ERRORNO.AMBIGUOUS_ROURE_ADDR) {
//起终点或途经点地址有岐义，通过以下接口获取建议查询信息
//result.getSuggestAddrInfo()
return;
}
if (result.error == SearchResult.ERRORNO.NO_ERROR) {
TransitRouteOverlay overlay = new MyTransitRouteOverlay(mBaidumap);
mBaidumap.setOnMarkerClickListener(overlay);
overlay.setData(result.getRouteLines().get(0));
overlay.addToMap();
overlay.zoomToSpan();
}
}
public void onGetDrivingRouteResult(DrivingRouteResult result) {
//
}
};
第三步，设置公交线路规划检索监听者；
mSearch.setOnGetRoutePlanResultListener(listener);
第四步，准备检索起、终点信息；
PlanNode stNode = PlanNode.withCityNameAndPlaceName("北京", "龙泽");
PlanNode enNode = PlanNode.withCityNameAndPlaceName("北京", "西单");
第五步，发起公交线路规划检索；
mSearch.transitSearch((new TransitRoutePlanOption())
.from(stNode)
.city("北京")
.to(enNode));
第六步，释放检索实例；
mSearch.destory();
其他的三种路线规划的大致步奏和公交路线大致相同，可以参考下。
这里我们就直接上代码了（里面做了解释）：
