获取当前位置城市名称,android

Question

我正在编写一个Android应用程序来获取当前位置的城市名称,我得到了正确的纬度和经度,但我无法获得城市名称.这是我的代码:

// To get City-Name from coordinates
String cityName = null;               
Geocoder gcd = new Geocoder(getBaseContext(), Locale.getDefault());              
List<Address> addresses = null;  
try {  
    addresses = gcd.getFromLocation(loc.getLatitude(), loc.getLongitude(), 1);  
    if (addresses.size() > 0)  
    System.out.println(addresses.get(0).getLocality());  
    cityName = addresses.get(0).getLocality();  
} catch (IOException e) {             
    e.printStackTrace();  
} 

String s = longitude + "\n" + latitude + "\n\nMy Currrent City is: " + cityName;
editLocation.setText(s);

Answer 1

 public String getLocationName(double lattitude, double longitude) {

    String cityName = "Not Found";
    Geocoder gcd = new Geocoder(getBaseContext(), Locale.getDefault());
    try {

        List<Address> addresses = gcd.getFromLocation(lattitude, longitude,
                10);

        for (Address adrs : addresses) {
            if (adrs != null) {

                String city = adrs.getLocality();
                if (city != null && !city.equals("")) {
                    cityName = city;
                    System.out.println("city ::  " + cityName);
                } else {

                }
                // // you should also try with addresses.get(0).toSring();

            }

        }
    } catch (IOException e) {
        e.printStackTrace();
    }
    return cityName;

}

试试这个代码

Geocoder geocoder = new Geocoder(this, Locale.ENGLISH);

 try {
 List<Address> addresses = geocoder.getFromLocation(yourLATITUDE, yourLONGITUDE, 1);

 if(addresses != null) {
 Address returnedAddress = addresses.get(0);
 StringBuilder strReturnedAddress = new StringBuilder("Address:\n");
 for(int i=0; i<returnedAddress.getMaxAddressLineIndex(); i++) {
 strReturnedAddress.append(returnedAddress.getAddressLine(i)).append("\n");
  }
 yourtextbox.setText(strReturnedAddress.toString());
 }
 else{
 myAddress.setText("No Address returned!");
 }
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
myAddress.setText("Canont get Address!");
}
