从坐标获取国家？

Question

如何在Android中获取国家/地区名称,如果已知地理坐标？如何使它成为最简单的方法？

Answer 1

干得好

Geocoder gcd = new Geocoder(context, Locale.getDefault());
List<Address> addresses = gcd.getFromLocation(lat, lng, 1);

    if (addresses.size() > 0)
     {  
       String countryName=addresses.get(0).getCountryName();
     }

Answer 2

使用下面的功能.

public void getAddress(double lat, double lng) {
    Geocoder geocoder = new Geocoder(HomeActivity.mContext, Locale.getDefault());
    try {
        List<Address> addresses = geocoder.getFromLocation(lat, lng, 1);
        Address obj = addresses.get(0);
        String add = obj.getAddressLine(0);
        GUIStatics.currentAddress = obj.getSubAdminArea() + ","
                + obj.getAdminArea();
        GUIStatics.latitude = obj.getLatitude();
        GUIStatics.longitude = obj.getLongitude();
        GUIStatics.currentCity= obj.getSubAdminArea();
        GUIStatics.currentState= obj.getAdminArea();
        add = add + "\n" + obj.getCountryName();
        add = add + "\n" + obj.getCountryCode();
        add = add + "\n" + obj.getAdminArea();
        add = add + "\n" + obj.getPostalCode();
        add = add + "\n" + obj.getSubAdminArea();
        add = add + "\n" + obj.getLocality();
        add = add + "\n" + obj.getSubThoroughfare();

        Log.v("IGA", "Address" + add);
        // Toast.makeText(this, "Address=>" + add,
        // Toast.LENGTH_SHORT).show();

        // TennisAppActivity.showDialog(add);
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
        Toast.makeText(this, e.getMessage(), Toast.LENGTH_SHORT).show();
    }
}

将以下权限添加到清单中

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>

用这个

try {
        Geocoder geo = new Geocoder(this.getApplicationContext(), Locale.getDefault());
        List<Address> addresses = geo.getFromLocation(location.getLatitude(), location.getLongitude(), 1);
        if (addresses.isEmpty()) {
            placeName.setText("Waiting for Location");
        }
        else {
            if (addresses.size() > 0) {
                placeName.setText(addresses.get(0).getFeatureName() + ", " + addresses.get(0).getLocality() +", " + addresses.get(0).getAdminArea() + ", " + addresses.get(0).getCountryName());
            }
        }
    }
    catch(Exception e){
        Toast.makeText(this, "No Location Name Found", 600).show();
    }

在清单文件中使用它

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
