Android 开发百度地图之五 路线规划
写到这里差不多百度地图系列要讲得东西也讲的差不多了。这篇博文主要是讲，百度地图的路线规划这个功能，本次例子以驾车路线规划来说明的。
- 在上个博文百度地图之四 Poi的demo 的基础上我们添加了一个搜索路线的按钮。
- 首先先获取起始点的坐标，然后调用路线规划接口主要代码如下
LatLng from = new LatLng(Double.parseDouble(mStartPosition.getLatitude()),
Double.parseDouble(mStartPosition.getLongitude()));
LatLng dest = new LatLng(Double.parseDouble(mEndPosition.getLatitude()),
Double.parseDouble(mEndPosition.getLongitude()));
//设置起终点信息，对于tranist search 来说，城市名无意义
PlanNode stNode = PlanNode.withLocation(from);
PlanNode enNode = PlanNode.withLocation(dest);
// 实际使用中请对起点终点城市进行正确的设定
mSearch.drivingSearch((new DrivingRoutePlanOption())
.from(stNode)
.to(enNode));- 调用完接口后还需监听返回的结果，当然因为我这边是调用的驾车路线的接口，所以只监听驾车的路线返回结果，还有走路和坐车两种的路线规划，如有需要也可以自行试试。
//////////////////////////////////route plan
@Override
public void onGetWalkingRouteResult(WalkingRouteResult walkingRouteResult) {
}
@Override
public void onGetTransitRouteResult(TransitRouteResult transitRouteResult) {
}
@Override
public void onGetDrivingRouteResult(DrivingRouteResult result) {
if (result == null || result.error != SearchResult.ERRORNO.NO_ERROR) {
Toast.makeText(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) {
mBaiduMap.clear();
// mroute = result.getRouteLines().get(0);
DrivingRouteOverlay overlay = new MyDrivingRouteOverlay(mBaiduMap);
mrouteOverlay = overlay;
mBaiduMap.setOnMarkerClickListener(overlay);
overlay.setData(result.getRouteLines().get(0));
overlay.addToMap();
overlay.zoomToSpan();
}
}
//定制RouteOverly
private class MyDrivingRouteOverlay extends DrivingRouteOverlay {
public MyDrivingRouteOverlay(BaiduMap baiduMap) {
super(baiduMap);
}
@Override
public BitmapDescriptor getStartMarker() {
return BitmapDescriptorFactory.fromResource(R.drawable.ic_baidumap_start);
}
@Override
public BitmapDescriptor getTerminalMarker() {
return BitmapDescriptorFactory.fromResource(R.drawable.ic_baidumap_destination);
}
}
//////////////////////////////////route plan- 最后要主要一点baidu.mapapi.overlayutil.DrivingRouteOverlay 和baidu.mapapi.overlayutil.OverlayManager 两个类是没有在百度地图sdk 中的，需要从将官方的demo 中的baidu.mapapi.overlayutil文件夹拷贝到自己的工程java 文件夹下。才可以调用路线规划。
