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
  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);
    }
