百度地圖開發(六)檢索定位附近街道資訊並展示
阿新 • • 發佈：2018-11-29
效果:
主要程式碼就是根據經緯度獲取經緯度附近周邊的資訊
/** * 根據經緯度獲取定位周邊街道資訊 * */ private void setPopupTipsInfo(LatLng latLng) { //設定反地理編碼位置座標 ReverseGeoCodeOption option = new ReverseGeoCodeOption(); option.location(latLng); //發起反地理編碼請求 geoCoder.reverseGeoCode(option); //為地理編碼查詢物件設定一個請求結果監聽器 geoCoder.setOnGetGeoCodeResultListener(new OnGetGeoCoderResultListener() { @Override public void onGetGeoCodeResult(GeoCodeResult geoCodeResult) { if (geoCodeResult == null || geoCodeResult.error != SearchResult.ERRORNO.NO_ERROR) { Toast.makeText(MainActivity.this, "檢索錯誤", Toast.LENGTH_SHORT).show(); return; } LatLng lat = new LatLng(geoCodeResult.getLocation().latitude, geoCodeResult.getLocation().longitude); geoCoder.reverseGeoCode(new ReverseGeoCodeOption().location(lat)); MapStatusUpdate u = MapStatusUpdateFactory.newLatLng(lat); mBaiduMap.clear(); mBaiduMap.animateMapStatus(u); } @Override public void onGetReverseGeoCodeResult(ReverseGeoCodeResult reverseGeoCodeResult) { if (reverseGeoCodeResult == null || reverseGeoCodeResult.error != SearchResult.ERRORNO.NO_ERROR) { Toast.makeText(MainActivity.this, "cuowu", Toast.LENGTH_SHORT).show(); } else { Log.e("baidulist", "" + reverseGeoCodeResult.getPoiList()); datas.clear(); datas2.clear(); List<PoiInfo> poiList = reverseGeoCodeResult.getPoiList(); if (poiList != null && poiList.size() > 0) { for (int i = 0; i < poiList.size(); i++) { datas.add(poiList.get(i).name); datas2.add(poiList.get(i).address); } } adapter.notifyDataSetChanged(); } } }); }
滑動地圖後呼叫這個方法就能獲取滑動後經緯度的周邊資訊:
/** * 滑動後的經緯度 * */ mBaiduMap.setOnMapStatusChangeListener(new BaiduMap.OnMapStatusChangeListener() { @Override public void onMapStatusChangeStart(MapStatus mapStatus) { } @Override public void onMapStatusChangeStart(MapStatus mapStatus, int i) { } @Override public void onMapStatusChange(MapStatus mapStatus) { } @Override public void onMapStatusChangeFinish(MapStatus mapStatus) { LatLng _latLng = mapStatus.target; Log.e("滑動後的經緯度", "經度:" + _latLng.longitude + "緯度:" + _latLng.latitude); setPopupTipsInfo(_latLng); } });
