百度地图3.1教程—检索功能演示

还记得两天前 我在找公交接口，非常不幸。接口有些查不到，几年的前的数据，哎 。算了呗，突然想起来了百度地图有这个功能，结果去看了API，尼玛这API 改的我都不认识  源代码在最小面

说好的MK开头的数据呢 去哪了，仅仅有从新看了。想从站点找点数据看看结果，找不到了，都是曾经API，好吧 自己写一篇 给大家补全吧。

至于Demo配置我就不说了 。请參考上一篇文章.......

由于仅仅是做研究用的。所以UI做的不是非常美观 仅仅是把数据放到上面去了。 UI例如以下

这个仅仅是教学教程所以 UI做的比較丑，只是这个代码你能够拷贝到你的APP里做成查询公交的功能，待完好。。。

。。

。。。。。。

一个button点击事件。联网请求数据，返回在Textview和listview显示

-----------第一步。发起POI检索。获取对应线路的UID；------------

先用poi检索查询 全部公交信息返回，这里是上一节就讲过的内容 我就不叙述了。

<pre name="code" class="java">    private void initMap() {poiSearch = PoiSearch.newInstance();poiSearch.setOnGetPoiSearchResultListener(onGetPoiSearchResultListener );//当公交信息出现以后，会出发这个监听器,这部分会在后面解说mBusLineSearch=BusLineSearch.newInstance();mBusLineSearch.setOnGetBusLineSearchResultListener(onGetBusLineSearchResultListener);}

-----第二步，通过button的点击事件我们出发检索事件------

    private void iniview() {button1 = (Button) findViewById(R.id.button1);search_result = (TextView) findViewById(R.id.result);bus_station = (ListView) findViewById(R.id.bus_station);button1.setOnClickListener(this);}

/*Button的点击事件处理，进行联网检索任务*/@Overridepublic void onClick(View view) {switch (view.getId()) {case R.id.button1:poiSearch.searchInCity((new PoiCitySearchOption())  .city("深圳")  .keyword("46")  );break;default:break;}}

----------------第三步。通过联网 百度会返回一些公交数据。到回调接口 --------------------

//    --------------------------------POI检索-----------------------OnGetPoiSearchResultListener onGetPoiSearchResultListener  = new OnGetPoiSearchResultListener() {@Overridepublic void onGetPoiResult(PoiResult result) {if (result == null || result.error != SearchResult.ERRORNO.NO_ERROR) {  return;  }  //遍历全部POI。找到类型为公交线路的POI  for (PoiInfo poi : result.getAllPoi()) {  if (poi.type == PoiInfo.POITYPE.BUS_LINE ||poi.type == PoiInfo.POITYPE.SUBWAY_LINE) {  busLineId = poi.uid;mBusLineSearch.searchBusLine((new BusLineSearchOption()  .city("深圳")  .uid(busLineId)));break;  } }  }//后面是具体信息@Overridepublic void onGetPoiDetailResult(PoiDetailResult poiDetailResult) {}};
//  --------------------------------POI检索-----------------------

------------------第四步 触发onGetBusLineSearchResultListener接口  从接口里的result里去取出我们要的数据

    //----------------------------bus检索-------------------------------------OnGetBusLineSearchResultListener onGetBusLineSearchResultListener=new OnGetBusLineSearchResultListener() {@Overridepublic void onGetBusLineResult(BusLineResult result) {Date startTime = result.getStartTime();Date endTime = result.getEndTime();String start = Commutils.dataToString(startTime);String end = Commutils.dataToString(endTime);String busLineName = result.getBusLineName();search_result.setText(start+"--"+end+"\n"+busLineName);List<BusStation> stations = result.getStations();List<String>list=new ArrayList<String>(); for (int i = 0; i < stations.size(); i++) {String title = stations.get(i).getTitle();list.add(title);}ArrayAdapter<String>adapter=new ArrayAdapter<String>(BusLineSearchDemo.this, android.R.layout.simple_list_item_1,list); bus_station.setAdapter(adapter);}};//----------------------------bus检索-------------------------------------

我就去了  最早时间 和最晚时间 还有 经过的站 其它的你们能够自行 扩展一下

   //----------------------------bus检索-------------------------------------OnGetBusLineSearchResultListener onGetBusLineSearchResultListener=new OnGetBusLineSearchResultListener() {@Overridepublic void onGetBusLineResult(BusLineResult result) {Date startTime = result.getStartTime();Date endTime = result.getEndTime();String start = Commutils.dataToString(startTime);String end = Commutils.dataToString(endTime);String busLineName = result.getBusLineName();search_result.setText(start+"--"+end+"\n"+busLineName);List<BusStation> stations = result.getStations();List<String>list=new ArrayList<String>(); for (int i = 0; i < stations.size(); i++) {String title = stations.get(i).getTitle();list.add(title);}ArrayAdapter<String>adapter=new ArrayAdapter<String>(BusLineSearchDemo.this, android.R.layout.simple_list_item_1,list); bus_station.setAdapter(adapter);}};//----------------------------bus检索-------------------------------------
