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）

汽车服务	汽车销售	汽车维修	摩托车服务	餐饮服务
购物服务	生活服务	体育休闲服务	医疗保健服务	住宿服务
风景名胜	商务住宿	政府机构及社会团体	科教文化服务	交通设施服务
金融保险服务	公司企业	道路附属设施	地名地址信息	公共设施

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

    @Override
    public 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() {
            @Override
            public 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:
