你好,我正在从事Android开发。我已经创建了一个GPS应用程序来获取当前位置。现在,如何从纬度和经度值中获取国家名称?这可行吗?请帮助我,谢谢:)
以下是我使用的代码:
public class AndroidGPSTrackingActivity extends Activity {
Button btnShowLocation;
// GPSTracker class
GPSTracker gps;
String countryCode,countryName;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
btnShowLocation = (Button) findViewById(R.id.btnShowLocation);
// show location button click event
btnShowLocation.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View arg0) {
// create class object
gps = new GPSTracker(AndroidGPSTrackingActivity.this);
// check if GPS enabled
if(gps.canGetLocation()){
double latitude = gps.getLatitude();
double longitude = gps.getLongitude();
Log.i("location", " "+latitude+" "+longitude);
// \n is for new line
try
{Geocoder gcd = new Geocoder(getApplicationContext(), Locale.getDefault());
List<Address> addresses = gcd.getFromLocation(latitude,longitude, 1);
if (addresses.size() > 0)
Toast.makeText(getApplicationContext(), "name "+addresses.get(0).getLocality(),Toast.LENGTH_SHORT).show();
//System.out.println(addresses.get(0).getLocality());
}
catch (IOException e) {
e.printStackTrace();
}
//Toast.makeText(getApplicationContext(), "Your Location is - \nLat: " + latitude + "\nLong: " + longitude+countryName +" "+countryCode, Toast.LENGTH_LONG).show();
}else{
// can't get location
// GPS or Network is not enabled
// Ask user to enable GPS/network in settings
gps.showSettingsAlert();
}
}
});
}
}
