![]() | 本地查询可以查询指定区域内诸如宾馆,邮局等用户感兴趣的地方。其使用方法和地址查询非常类似。 下面示例查询32.0616667, 118.7777778为中心点一定区域内宾馆的信息。 [java] //--------------------------------- PACKAGE ------------------------------------ package com.pstreets.gisengine.demo.midp; //--------------------------------- IMPORTS ------------------------------------ import com.mapdigit.gis.MapPoint; import com.mapdigit.gis.geometry.GeoLatLng; import com.mapdigit.gis.raster.MapType; import com.mapdigit.gis.service.IGeocodingListener; import com.pstreets.gisengine.demo.MapDemoMIDP; import javax.microedition.lcdui.Command; import javax.microedition.lcdui.CommandListener; import javax.microedition.lcdui.Display; import javax.microedition.lcdui.Displayable; //[------------------------------ MAIN CLASS ----------------------------------] //--------------------------------- REVISIONS ---------------------------------- // Date Name Tracking # Description // -------- ------------------- ------------- -------------------------- // 28JAN2011 James Shen Initial Creation //////////////////////////////////////////////////////////////////////////////// /** * map pan demo for Guidebee Map API on MIDP platform. */ public class MapLocalSearchMIDP extends MapDemoMIDP implements CommandListener, IGeocodingListener { private Command mapFindAddressCommand = new Command("Find Address", Command.OK, 1); public void startApp() { init(); canvas.addCommand(mapFindAddressCommand); map.setGeocodingListener(this); canvas.setCommandListener(this); GeoLatLng center = new GeoLatLng(32.0616667, 118.7777778); map.setCenter(center, 13, MapType.MICROSOFTCHINA); Display.getDisplay(this).setCurrent(canvas); } public void commandAction(Command c, Displayable d) { if (c == mapFindAddressCommand) { String name = "??"; GeoLatLng screenCenter = map.getScreenCenter(); map.getLocations(name, 0, screenCenter, map.getScreenBounds(screenCenter)); } } public void done(String query, MapPoint[] result) { if (result != null) { map.panTo(result[0].getPoint()); for (int i = 0; i < result.length; i++) { System.out.println(result.objectNote); } } } } //--------------------------------- PACKAGE ------------------------------------ package com.pstreets.gisengine.demo.midp; //--------------------------------- IMPORTS ------------------------------------ import com.mapdigit.gis.MapPoint; import com.mapdigit.gis.geometry.GeoLatLng; import com.mapdigit.gis.raster.MapType; import com.mapdigit.gis.service.IGeocodingListener; import com.pstreets.gisengine.demo.MapDemoMIDP; import javax.microedition.lcdui.Command; import javax.microedition.lcdui.CommandListener; import javax.microedition.lcdui.Display; import javax.microedition.lcdui.Displayable; //[------------------------------ MAIN CLASS ----------------------------------] //--------------------------------- REVISIONS ---------------------------------- // Date Name Tracking # Description // -------- ------------------- ------------- -------------------------- // 28JAN2011 James Shen Initial Creation //////////////////////////////////////////////////////////////////////////////// /** * map pan demo for Guidebee Map API on MIDP platform. */ public class MapLocalSearchMIDP extends MapDemoMIDP implements CommandListener, IGeocodingListener { private Command mapFindAddressCommand = new Command("Find Address", Command.OK, 1); public void startApp() { init(); canvas.addCommand(mapFindAddressCommand); map.setGeocodingListener(this); canvas.setCommandListener(this); GeoLatLng center = new GeoLatLng(32.0616667, 118.7777778); map.setCenter(center, 13, MapType.MICROSOFTCHINA); Display.getDisplay(this).setCurrent(canvas); } public void commandAction(Command c, Displayable d) { if (c == mapFindAddressCommand) { String name = "??"; GeoLatLng screenCenter = map.getScreenCenter(); map.getLocations(name, 0, screenCenter, map.getScreenBounds(screenCenter)); } } public void done(String query, MapPoint[] result) { if (result != null) { map.panTo(result[0].getPoint()); for (int i = 0; i < result.length; i++) { System.out.println(result.objectNote); } } } } 本地查询方法 public void getLocations(String address,int start,GeoLatLng center,GeoBounds bound, IGeocodingListener listener); 指定中心点和查询区域。本地查询可以多次返回结果,start为查询结果起始顺序,每次返回结果在SearchOptions 中定义,缺省每次返回4个。 www.atcpu.com 上述结果返回内容为,具体结果可能不同。 “晶丽酒店025-83310818 025-83310818212223 025-86636636 ” “城市名人酒店025-83123333 025-83123888 ” “南京玄武饭店 025-83358888 ” “Sofitel Galaxy Nanjing – 南京索菲特银河大酒店025-83718888 作者:mapdigit | |
