根据地名获取经纬度.doc

根据地名获取经纬度1. 根据goole api得到经纬度：String strUrl= /maps/api/geocode/xml?address=0&sensor=false; URL url;InputStream in = null;String str = ;String lnglat = ;try url = new URL(MessageFormat.format(strUrl, strCurrent);URLConnection uc = url.openConnection();in = uc.getInputStream();/*Object obj = url.getContent();InputStream in = (InputStream) obj;*/byte tt = new bytein.available();int z;while (z = in.read(tt, 0, tt.length) != -1) str = new String(tt, utf-8);/System.out.println(str);in.close(); catch (MalformedURLException e) e.printStackTrace(); catch(SocketException e) lnglat = 00000000000 + + 0000000000;System.out.println(list.get(i) + + lnglat); catch (IOException e) e.printStackTrace();if(str != ) lnglat = getString(str);System.out.println(list.get(i) + + lnglat);try Thread.sleep(1000); catch (InterruptedException e) e.printStackTrace();public static String getLngAndLat(InputStream instream) DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();DocumentBuilder db = null;try db = dbf.newDocumentBuilder(); catch (ParserConfigurationException e) e.printStackTrace();Document doc = null;try doc = db.parse(instream); catch (SAXException e) e.printStackTrace(); catch (IOException e) e.printStackTrace();Element root = doc.getDocumentElement();NodeList points = root.getElementsByTagName(location);String lnglat = ;for(int i=0;ipoints.getLength();i+) Element point = (Element)points.item(i);lnglat = point.getAttribute(lng) + + point.getAttribute(lat);return lnglat;public static String getString(String xmlString) int a = xmlString.indexOf();int b = xmlString.indexOf();int c = xmlString.indexOf();int d = xmlString.indexOf();String lat = xmlString.substring(a+5, b);String lng = xmlString.substring(c + 5, d);return lng + + lat;2. 根据“百度API”得到地名的经纬度：Html 代码是： 地址解析获取function showMap() var name = new Array(祁门县平里镇胜丰村卫生室,祁门县祁山镇沙湾村卫生室,祁门县祁山镇榨坞村卫生室);for(i=0;iname.length;i+) Pause(this,3000); getJW(namei,i+10000); function getJW(name,num)/获取经纬度var map = new BMap.Map(container);map.centerAndZoom(new BMap.Point(118.315544, 29.703859), 11);var myGeo = new BMap.Geocoder(); var addname = name; var i=num;myGeo.getPoint(addname, function(point) if (point) /document.getElementById(show).innerHTML=addname+ +point.lng + + point.lat + | ; document.getElementById(show).appendChild(document.createTextNode(i+ +point.lng + + point.lat + +addname+ ; ); else document.getElementById(show).appendChild(document.createTextNode(i+ +0000000000 00000000+ +addname+; ) , 黄山市);function Pause(obj,iMinSecond)/暂停方法 if (window.eventList=null) window.eventList=new Array(); var ind=-1; for (var i=0;iwindow.eventList.length;i+) if (window.eventListi=null) window.eventListi=obj; ind=i; break; if (ind=-1) ind=window.eventList.length; window.eventListind=obj; setTimeo
