地址反编码是通过经纬度查询对应的地名,下面示例是查询经纬度为118.777802, 32.061699对应的地名,结果为”中国江苏省南京市鼓楼区渊声巷41号”。
package com.pstreets.gisengine.demo; import com.mapdigit.gis.DigitalMap; import com.mapdigit.gis.MapPoint; import com.mapdigit.gis.geometry.GeoLatLng; import com.mapdigit.gis.service.IReverseGeocodingListener; import com.mapdigit.gis.service.IpAddressLocation; import com.pstreets.gisengine.R; import com.pstreets.gisengine.SharedMapInstance; import android.app.Activity; import android.os.Bundle; import android.view.Menu; import android.view.MenuInflater; import android.view.MenuItem; public class MapReverseGeocoding extends Activity implements IReverseGeocodingListener { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); } @Override public void onStart() { super.onStart(); GeoLatLng center = new GeoLatLng(32.0616667, 118.7777778); SharedMapInstance.map.setCenter(center, 15, com.mapdigit.gis.raster.MapType.MICROSOFTCHINA); SharedMapInstance.map.setReverseGeocodingListener(this); } @Override public boolean onCreateOptionsMenu(Menu menu) { MenuInflater inflater = getMenuInflater(); inflater.inflate(R.menu.mapgeocoding_menu, menu); return true; } @Override public boolean onOptionsItemSelected(MenuItem item) { // Handle item selection switch (item.getItemId()) { case R.id.findaddress: SharedMapInstance.map.getReverseLocations("32.061699,118.777802"); return true; default: return super.onOptionsItemSelected(item); } } @Override public void done(String arg0, MapPoint[] result) { if (result != null) { SharedMapInstance.map.panTo(result[0].getPoint()); } } @Override public void readProgress(int bytes, int total) { } }
注意使用字符串经纬度格式时,纬度在前,经度在后,如果反了,则返回的地名或能为空或都跑到外国去了。结果也是一个数组,一般到第一个结果,后面结果是更大的区域或是距离相对较远的地名。
