POI（Point of Interest）

準(zhǔn)備

高德的搜索SDK（我用的是AMap_Search_V6.5.0_20180930.jar）,這里提供高德官方文檔入口：高德搜索

實(shí)現(xiàn)

１、定義

private PoiSearch.Query query;
private PoiSearch poiSearch;
private List<String> addressNameList=new ArrayList<>();//存取標(biāo)題列表
private List<HashMap<String,Double>> addressList=new ArrayList<>();//存取經(jīng)緯度列表

２蔬蕊、實(shí)例化及使用

query = new PoiSearch.Query(searchContent, "", "");// 第一個參數(shù)表示搜索字符串癌椿，第二個參數(shù)表示poi搜索類型逾礁，第三個參數(shù)表示poi搜索區(qū)域（空字符串代表全國）

    query.setPageSize(10);
    query.setPageNum(０);

    poiSearch = new PoiSearch(this, query);
    poiSearch.setOnPoiSearchListener(this);
    poiSearch.searchPOIAsyn();

３许师、回調(diào)方法里面接收數(shù)據(jù)

        public void onPoiSearched(PoiResult result, int rCode) {
            if (rCode == AMapException.CODE_AMAP_SUCCESS) {
                addressList.clear();
                addressNameList.clear();
                if (result != null && result.getQuery() != null) {// 搜索poi的結(jié)果
                    if (result.getQuery().equals(query)) {// 是否是同一條
                        List<PoiItem> poiItems = poiResult.getPois();
                        List<SuggestionCity> suggestionCities = poiResult
                                .getSearchSuggestionCitys();

                        if (poiItems != null && poiItems.size() > 0) {
                            for (PoiItem item:poiItems) {
                                LatLonPoint point=item.getLatLonPoint();
                                HashMap<String,Double> map=new HashMap<>();
                                map.put("lng",point.getLongitude());
                                map.put("lat",point.getLatitude());
                                addressList.add(map);
                                addressNameList.add(item.getTitle());
                            }
                            
                        } else if (suggestionCities != null
                                && suggestionCities.size() > 0) {
                            for (PoiItem item:poiItems) {
                                LatLonPoint point=item.getLatLonPoint();
                                HashMap<String,Double> map=new HashMap<>();
                                map.put("lng",point.getLongitude());
                                map.put("lat",point.getLatitude());
                                addressList.add(map);
                                addressNameList.add(item.getTitle());
                            }
                        
                        } 
                    }
                }
            }
        }

注意

１洋闽、addressList和addressNameList同時添加和清空數(shù)據(jù)瓤球，并保證數(shù)據(jù)源來自同一個實(shí)體溺忧；

２咏连、展示的時候直接用ListView配合ArrayAdapter，然后傳入addressNameList就行鲁森；

３祟滴、在ListView的onItemClickListener的OnItemClick()中通過position在addressList中先拿到HashMap,然后在通過鍵就能拿到經(jīng)緯度了＾＿＾
