1、 geocoderSearch = new GeocodeSearch(this); geocoderSearch.setOnGeocodeSearchListener(this); 重寫他的onGeocodeSearched、onRegeocodeSearched的兩個Void的方法來實現地理碼的轉化和逆轉。2、地理碼轉化成經緯度 主要代碼： // 第一個參數表示地址，第二個參數表示查詢城市，中文或者中文全拼，citycode、adcode， 都不寫則默認所有城市 GeocodeQuery query = new GeocodeQuery(name, null); geocoderSearch.getFromLocationNameAsyn(query);// 設置同步地理編碼請求地理編碼查詢回調@Overridepublic void onGeocodeSearched(GeocodeResult result, int rCode) {dismissDialog();if (rCode == 1000) {if (result != null && result.getGeocodeAddressList() != null&& result.getGeocodeAddressList().size() > 0) {GeocodeAddress address = result.getGeocodeAddressList().get(0)double dimensionality = address.getLatLonPoint().getLatitude();double longitude = address.getLatLonPoint().getLongitude();LatLng latlng = new LatLng(dimensionality, longitude);aMap.animateCamera(CameraUpdateFactory.newLatLngZoom(latlng, 15));geoMarker.setPosition(AMapUtil.convertToLatLng(address.getLatLonPoint()));addressName = "經緯度值:" + address.getLatLonPoint() + "\n位置描述:"+ address.getFormatAddress();ToastUtil.show(GeocoderActivity.this, addressName);} else {ToastUtil.show(GeocoderActivity.this, "shiasa");}} else {ToastUtil.showerror(this, rCode);}} 3、通過經緯度轉化為地理地址LatLonPoint latLonPoint = new LatLonPoint(39.90865, 116.39751); // 第一個參數表示一個Latlng，第二參數表示范圍多少米，第三個參數表示是火系坐標系還是GPS原生坐標系 RegeocodeQuery query = new RegeocodeQuery(latLonPoint, 200, GeocodeSearch.AMAP);// 設置同步逆地理編碼請求 geocoderSearch.getFromLocationAsyn(query);逆地理編碼回調 @Overridepublic void onRegeocodeSearched(RegeocodeResult result, int rCode) {dismissDialog();if (rCode == 1000) {if (result != null && result.getRegeocodeAddress() != null&& result.getRegeocodeAddress().getFormatAddress() != null) {addressName = result.getRegeocodeAddress().getFormatAddress()+ "附近";aMap.animateCamera(CameraUpdateFactory.newLatLngZoom(AMapUtil.convertToLatLng(latLonPoint), 15));regeoMarker.setPosition(AMapUtil.convertToLatLng(latLonPoint));ToastUtil.show(GeocoderActivity.this, addressName);} else {ToastUtil.show(GeocoderActivity.this, "shiasa");}} else {ToastUtil.showerror(this, rCode);}} 4、精華一句 latlng=AMapUtil.convertToLatLng(latLonPoint) AMapUtil 工具類 public class AMapUtil {/*** 判斷edittext是否null*/public static String checkEditText(EditText editText) {if (editText != null && editText.getText() != null&& !(editText.getText().toString().trim().equals(""))) {return editText.getText().toString().trim();} else {return "";}}public static Spanned stringToSpan(String src) {return src == null ?
