高德地图开发(三)检索定位附近街道信息并进行列表展示

根据经纬度获取周边街道信息列表,有搜索的方法

    /*** 检索* */public void setSearchApi(Double wei, Double jing) {mList.clear();myAdapter.notifyDataSetChanged();PoiSearch.Query query = new PoiSearch.Query("", "", "");query.setPageSize(20);PoiSearch search = new PoiSearch(this, query);search.setBound(new PoiSearch.SearchBound(new LatLonPoint(wei, jing), 10000));search.setOnPoiSearchListener(this);search.searchPOIAsyn();//up}

其中PoiSearch.Query query = new PoiSearch.Query("", "", "");是检索的条件,第一个参数为搜索的关键字，第二个参数为搜索类型（一共有20种,参考下方表格）

第三个参数为搜索城市，是必填参数，关键字和类型至少输入一个,query.setPageSize(20);是设置每页最多返回多少条poiitem 

然后是回调

    @Overridepublic void onPoiSearched(PoiResult result, int i) {PoiSearch.Query query = result.getQuery();ArrayList<PoiItem> pois = result.getPois();for (PoiItem poi : pois) {Log.e("fanhuidepois","\ngetAdCode" + poi.getAdCode() +"\ngetAdName" + poi.getAdName() +"\ngetBusinessArea" + poi.getBusinessArea() +"\ngetCityCode" + poi.getCityCode() +"\ngetCityName" + poi.getCityName()+"\ngetDirection"+poi.getDirection()+"\ngetEmail"+poi.getEmail()+"\ngetParkingType"+poi.getParkingType()+"\ngetPoiId"+poi.getPoiId()+"\ngetPostcode"+poi.getPostcode()+"\ngetProvinceCode"+poi.getProvinceCode()+"\ngetProvinceName"+poi.getProvinceName()+"\ngetShopID"+poi.getShopID()+"\ngetSnippet"+poi.getSnippet()+"\ngetTel"+poi.getTel()+"\ngetTitle"+poi.getTitle()+"\ngetTypeCode"+poi.getTypeCode()+"\ngetTypeDes"+poi.getTypeDes()+"\ngetWebsite"+poi.getWebsite()+"\ngetDistance"+poi.getDistance()+"\ngetEnter"+poi.getEnter()+"\ngetExit"+poi.getExit()+"\ngetIndoorData"+poi.getIndoorData()+"\ngetLatLonPoint"+poi.getLatLonPoint()+"\ngetPhotos"+poi.getPhotos()+"\ngetPoiExtension"+poi.getPoiExtension()+"\ngetSubPois"+poi.getSubPois()+"\n");String name = poi.getCityName();//北京市String city = poi.getAdName();//海淀区String area = poi.getBusinessArea();//清河String snippet = poi.getSnippet();//街道地址String detail=poi.getTitle();LocationInfo info = new LocationInfo();info.setAddress(detail);info.setAddress2(name+city+area+snippet);LatLonPoint point = poi.getLatLonPoint();info.setLatitude(point.getLatitude());info.setLonTitude(point.getLongitude());mList.add(info);}myAdapter.notifyDataSetChanged();}

我把返回的所有信息数据都记录下来了,大家请自行参考,拿自己需要的数据

然后将这些数据用列表展示出来

    /*** 显示周边街道列表*/public void setShowList() {mList = new ArrayList<>();myAdapter = new MyAdapter(this, mList);LinearLayoutManager layoutManager = new LinearLayoutManager(this, LinearLayoutManager.VERTICAL, false);recyclerview.setLayoutManager(layoutManager);recyclerview.setAdapter(myAdapter);myAdapter.setOnItemClickListener(new MyAdapter.OnItemClickListener() {@Overridepublic void onClick(int position) {Toast.makeText(MainActivity.this, "\n地址" + mList.get(position).getAddress()+ "\n纬度" + mList.get(position).getLatitude()+ "\n经度" + mList.get(position).getLonTitude(), Toast.LENGTH_SHORT).show();}});}

到这里就能实现上面的效果,下面贴一下全部的代码,不懂的可以看一下:

LocationInfo类
 

/*** Created by */public class LocationInfo {private String address;private String address2;private Double Latitude;private Double LonTitude;public String getAddress() {return address;}public void setAddress(String address) {this.address = address;}public String getAddress2() {return address2;}public void setAddress2(String address2) {this.address2 = address2;}public Double getLatitude() {return Latitude;}public void setLatitude(Double latitude) {Latitude = latitude;}public Double getLonTitude() {return LonTitude;}public void setLonTitude(Double lonTitude) {LonTitude = lonTitude;}
}
