SOSO地图通过经度纬度取地址
搜索了很多网上通过经度纬度取地址的方法， 都是用的 Geocoder 对象的 Geocoder.getFromLocation 函数， 下面有例子， 但是经过我的测试， 无法获取地址。
网上找了资料， 可以使用互联网取地址，如下所示 ：
http://maps.googleapis.com/maps/api/geocode/xml?latlng=51.134545,101.401201&sensor=false&language=zh-CN
不过这种方法就是会造成多连接一次互联网， 返回的xml数据还要解析， 用户体验不是太好。
//该函数无法获取地址
private String getLocationAddress(GeoPoint point, double iLatitu, double iLongti)
{
String add = "";
//Geocoder geoCoder = new Geocoder(getBaseContext(), Locale.getDefault());
Geocoder geoCoder = new Geocoder(getBaseContext(), Locale.CHINA);
try
{
//Thread.sleep(5000);
//Location location = locManager.getLastKnownLocation(locManager.GPS_PROVIDER);
//List<Address> listAddresses = geoCoder.getFromLocation( point.getLatitudeE6() / 1E6, point.getLongitudeE6() / 1E6, 10);
//List places = geoCoder.getFromLocation(point.getLatitudeE6() / 1E6, point.getLongitudeE6() / 1E6, 5);
List<Address> listAddresses = geoCoder.getFromLocation( iLatitu, iLongti, 1);
List places = geoCoder.getFromLocation(iLatitu, iLongti, 1);
//Thread.sleep(5000);
//http://maps.googleapis.com/maps/api/geocode/xml?latlng=31.134545,121.401201&sensor=false&language=zh-CN
if (listAddresses.size() > 0)
{
Address address = listAddresses.get(0);
int maxLine = address.getMaxAddressLineIndex();
if (maxLine >= 2)
{
add = address.getAddressLine(1) + address.getAddressLine(2);
}
else
{
add = address.getAddressLine(1);
}
}
}
//catch (InterruptedException e)
//{
// add = "";
// e.printStackTrace();
//}
catch (IOException e)
{
add = "";
e.printStackTrace();
}
return add;
}
最终找了另外一种方法，就是使用 QSearchListener 对象， 然后实现 onGetReverseGeocoder 函数的内容即可取到地址。
QSearchListener listenerQsearch = new QSearchListener()
@Override
public void onGetReverseGeocoder(int resultCode, QPlaceMark addr)
下面为源码实现：
QSearchListener listenerQsearch = new QSearchListener() {
@Override
public void onGetReverseGeocoder(int resultCode, QPlaceMark addr) {
if (resultCode == QSearchListener.KQRESULT_OK)
{
Toast.makeText( KQDKActivity.this, addr.address, Toast.LENGTH_LONG).show();
}
else
{
Toast.makeText(KQDKActivity.this, "无结果", Toast.LENGTH_LONG).show();
}
}
@Override
public void onGetPoiSearch(int resultCode, QPoiResult poiResult) {
if (resultCode == QSearchListener.KQRESULT_OK) {
} else {
Toast.makeText(KQDKActivity.this, "无结果", Toast.LENGTH_LONG).show();
}
}
@Override
public void onGetBusLineSearch(int resultCode, QBusLineInfo busLineInfo) {
if (resultCode == QSearchListener.KQRESULT_OK) {
} else
Toast.makeText(KQDKActivity.this, "公交线路无结果", Toast.LENGTH_LONG).show();
}
@Override
public void onGetRouteSearchResult(int resultCode, QRouteSearchResult routeSearchResult) {
// TODO Auto-generated method stub
if (resultCode == QSearchListener.KQRESULT_OK) {
int type = routeSearchResult.routeSearchResultType;
if (type == QRouteSearchResult.KQROUTESEARCHRESULT_BUSROUTE) {
QBusRoutePlan plan = (QBusRoutePlan) routeSearchResult.routeSearchResult;
} else if (type == QRouteSearchResult.KQROUTESEARCHRESULT_DRIVEROUTE) {
QDriveRouteInfo info = (QDriveRouteInfo) routeSearchResult.routeSearchResult;
}
else if (type == QRouteSearchResult.KQROUTESEARCHRESULT_BUSLIST)
{
Toast.makeText(KQDKActivity.this, "路线搜索结果为选择列表", Toast.LENGTH_LONG).show();
QRouteQueryResultChoice choice = (QRouteQueryResultChoice)routeSearchResult.routeSearchResult;
mQsearch.setBusRoutePolicy(QSearch.KQBUS_ROUTE_POLICY_SHORTCUT);
mQsearch.busRouteSearchWithLocation("北京", choice.startList.get(0), choice.endList.get(0));
}
else if (type == QRouteSearchResult.KQROUTESEARCHRESULT_DRIVELIST)
{
Toast.makeText(KQDKActivity.this, "路线搜索结果为选择列表", Toast.LENGTH_LONG).show();
QRouteQueryResultChoice choice = (QRouteQueryResultChoice)routeSearchResult.routeSearchResult;
mQsearch.setDrivingRoutePolicy(QSearch.KQDRIVING_ROUTE_POLICY_SHORTCUT);
mQsearch.driveRouteSearchWithLocation("北京", choice.startList.get(0), "北京",choice.endList.get(0));
}
} else
Toast.makeText(KQDKActivity.this, "路线搜索无结果", Toast.LENGTH_LONG).show();
}
@Override
public void onGetSmartTrips(int resultCode, List<String> smartTrips) {
// TODO Auto-generated method stub
if (resultCode == QSearchListener.KQRESULT_OK) {
String s = null;
int num = smartTrips.size();
for (int i = 0; i < num; ++i) {
if (s == null) {
s = smartTrips.get(i);
} else {
s += "\n" + smartTrips.get(i);
}
}
Toast.makeText(KQDKActivity.this, s, Toast.LENGTH_LONG).show();
} else {
Toast.makeText(KQDKActivity.this, "路线搜索无结果", Toast.LENGTH_LONG).show();
}
}
@Override
public void onGetGeocoder(int resultCode, QGeocoderInfo geocodeInfo) {
// TODO Auto-generated method stub
if (resultCode == QSearchListener.KQRESULT_OK) {
String s = geocodeInfo.province + "\n" + geocodeInfo.city + "\n" + geocodeInfo.district;
Toast.makeText(KQDKActivity.this, s, Toast.LENGTH_LONG).show();
} else {
Toast.makeText(KQDKActivity.this, "无结果", Toast.LENGTH_LONG).show();
}
}
};
这样就可以直接从地图上取到经度纬度对应的地址。
