android百度地图之公交线路详情搜索
本篇文章可以实现百度公交线路搜索，可以选择多条线路，具体实现代码如下：
一、公交线路详情检索
获取公交线路的详情主要分来两步，1.获取公交线路的Uid，2.通过Uid获取公交线路详情。
1.获取公交线路的Uid：
/*
* 获得公交线路图的Uid，并且根据系Uid发起公交线路详情的检索
*
* @see
* com.baidu.mapapi.MKSearchListener#onGetPoiResult(com.baidu.mapapi
* .MKPoiResult, int, int)
*/
@Override
public void onGetPoiResult(MKPoiResult arg0, int arg1, int arg2) {
// TODO Auto-generated method stub
if (arg0 == null || arg2 != 0) {
Toast.makeText(MainActivity.this, "未找到结果", 1);
return;
}
// 定义一个公交线路描述类
MKPoiInfo mkPoiInfo = null;
// 获得本次就爱你所的公交线路的总站点
int totalPoiNum = arg0.getNumPois();
for (int i = 0; i < totalPoiNum; i++) {
mkPoiInfo = arg0.getPoi(i);
if (mkPoiInfo.ePoiType == 2) {
break;
}
}
mkSearch.busLineSearch("开封", mkPoiInfo.uid);
}
2.获取公交线路详情：
/*
* 得到公交线路图的详情
*
* @see
* com.baidu.mapapi.MKSearchListener#onGetBusDetailResult(com.baidu.
* mapapi.MKBusLineResult, int)
*/
@Override
public void onGetBusDetailResult(MKBusLineResult arg0, int arg1) {
// TODO Auto-generated method stub
if (arg0 == null || arg1 != 0) {
Toast.makeText(MainActivity.this, "未找到结果", 1);
return;
}
RouteOverlay routeOverlay = new RouteOverlay(MainActivity.this,
mapView);
routeOverlay.setData(arg0.getBusRoute());// 获得公交线路
mapView.getOverlays().clear();// 清楚公交站点的标识
mapView.getOverlays().add(routeOverlay);
mapView.invalidate();
// 采用动画形式描述公交站点
mapView.getController().animateTo(arg0.getBusRoute().getStart());
}
查询时，只需提供城市名和线路
mkSearch.poiSearchInCity("开封", "3");

return true;
}
@Override

// TODO Auto-generated method stub
return false;
}
}
二、多条线路显示
在同一个地图上显示多条导航线路，也只需要分两步完成，
1.定义起始点个终点
start = new MKPlanNode();
start.pt = new GeoPoint((int) (39.915 * 1E6), (int) (116.404 * 1E6));
end = new MKPlanNode();
end.pt = new GeoPoint(40057031, 116307852);
mkSearch.transitSearch("北京", start, end);
2.将所有的线路详情循环显示在地图上
@Override
public void onGetTransitRouteResult(MKTransitRouteResult arg0, int arg1) {
// TODO Auto-generated method stub
if (arg0 == null) {
return;
}
int planNum = arg0.getNumPlan();// 获取所有的驾车路线
for (int i = 0; i < planNum; i++) {
TransitOverlay overlay = new TransitOverlay(MainActivity.this,
mapView);
overlay.setData(arg0.getPlan(i));
mapView.getOverlays().add(overlay);
}
mapView.invalidate();
mapView.getController().animateTo(arg0.getStart().pt);
}
