百度地圖3.1教程—檢索功能示範

還記得兩天前 我在找公交介面，很不幸，介面有些查不到，幾年的前的資料，哎 ，算了唄，突然想起來了百度地圖有這個功能，結果去看了API，尼瑪這API 改的我都不認識 源碼在最小面

說好的MK開頭的資料呢 去哪了，只有從新看了，想從網站找點資料看看結果，找不到了，都是以前API，好吧 自己寫一篇 給大家補全吧。 

 

至於Demo配置我就不說了 ，請參考上一篇文章.......

因為只是做研究用的，所以UI做的不是很美觀 只是把資料放到上面去了。 UI如下

這個只是教學教程所以 UI做的比較醜，不過這個代碼你可以複製到你的APP裡做成查詢公交的功能，待完善。。。。。。。。。。。

一個button點擊事件，連網請求資料，返回在Textview和listview顯示

-----------第一步，發起POI檢索，擷取相應線路的UID；------------

先用poi檢索查詢 所有公交資訊返回，這裡是上一節就講過的內容 我就不敘述了。

<pre name="code" class="java">private void initMap() {poiSearch = PoiSearch.newInstance();poiSearch.setOnGetPoiSearchResultListener(onGetPoiSearchResultListener );//當公交資訊出現以後，會出發這個監聽器,這部分會在後面講解mBusLineSearch=BusLineSearch.newInstance();mBusLineSearch.setOnGetBusLineSearchResultListener(onGetBusLineSearchResultListener);}

 -----第二步，通過button的點擊事件我們出發檢索事件------

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的點擊事件處理，進行連網檢索任務*/@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，通過連網 百度會返回一些公交資料，到回調介面 --------------------           

//--------------------------------POI檢索-----------------------OnGetPoiSearchResultListener onGetPoiSearchResultListener  = new OnGetPoiSearchResultListener() {@Overridepublic void onGetPoiResult(PoiResult result) {  if (result == null || result.error != SearchResult.ERRORNO.NO_ERROR) {          return;      }      //遍曆所有POI，找到類型為公交線路的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;          }     }       }//後面是詳細資料@Overridepublic void onGetPoiDetailResult(PoiDetailResult poiDetailResult) {}};//--------------------------------POI檢索-----------------------

------------------第四步 觸發onGetBusLineSearchResultListener介面  從介面裡的result裡去取出我們要的資料

//----------------------------bus檢索-------------------------------------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檢索-------------------------------------

我就去了  最早時間 和最晚時間 還有 經過的站 其他的你們可以自行 擴充一下

//----------------------------bus檢索-------------------------------------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檢索-------------------------------------
