想了解android百度地图之公交线路详情搜索的相关内容吗，若。只如初见在本文为您仔细讲解百度地图之公交线路详情搜索的相关知识和一些Code实例，欢迎阅读和指正，我们先划重点：android地图搜索功能,android百度地图搜索,百度地图api,公交线路，下面大家一起来学习吧。

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");

      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

      // TODO Auto-generated method stub

    }

    @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;
        }
      }

      // TODO Auto-generated method stub

    }

    @Override
    public void onGetTransitRouteResult(MKTransitRouteResult arg0, int arg1) {
      // TODO Auto-generated method stub

    }

    @Override
    public void onGetWalkingRouteResult(MKWalkingRouteResult arg0, int arg1) {
      // TODO Auto-generated method stub

    }
  }

  @Override
  protected void onDestroy() {
    // TODO Auto-generated method stub
    super.onDestroy();
    if (bMapManager != null) {
      bMapManager.destroy();
      bMapManager = null;
    }
  }

  @Override
  protected void onResume() {
    // TODO Auto-generated method stub
    super.onResume();
    if (bMapManager != null) {
      bMapManager.start();
    }
  }

  @Override
  protected void onPause() {
    // TODO Auto-generated method stub
    super.onPause();
    if (bMapManager != null) {
      bMapManager.stop();
    }
  }

  @Override
  public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
  }

  @Override
  protected boolean isRouteDisplayed() {
    // 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);
    }
