如何获取城市名称在纬度和经度在android?

我想通过当前的位置城市名称,但我有经度和经度如何得到它? 我用button单击,然后我得到双值的经度和纬度。 我的代码在below.please帮助我。

谢谢!!

Button btnShowLocation; GPSTracker gps; @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 v) { // create class object gps = new GPSTracker(AndroidGPSTrackingActivity.this); // check if GPS enabled if(gps.canGetLocation()){ double latitude = gps.getLatitude(); double longitude = gps.getLongitude(); // \n is for new line Toast.makeText(getApplicationContext(), "Your Location is - \nLat: " + latitude + "\nLong: " + longitude, Toast.LENGTH_LONG).show(); }else{ gps.showSettingsAlert(); } } }); 

我编辑下面的代码,但没有得到cityname请帮助我!

 Button btnShowLocation; GPSTracker gps; String CityName; @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 v) { // create class object gps = new GPSTracker(AndroidGPSTrackingActivity.this); // check if GPS enabled if (gps.canGetLocation()) { double latitude = gps.getLatitude(); double longitude = gps.getLongitude(); Geocoder geocoder = new Geocoder( AndroidGPSTrackingActivity.this, Locale .getDefault()); List<Address> addresses; try { Log.v("log_tag", "latitude" + latitude); Log.v("log_tag", "longitude" + longitude); addresses = geocoder.getFromLocation(latitude, longitude, 1); Log.v("log_tag", "addresses+)_+++" + addresses); CityName = addresses.get(0).getAddressLine(0); Log.v("log_tag", "CityName" + CityName); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } // \n is for new line Toast.makeText( getApplicationContext(), "Your Location is - \nLat: " + latitude + "\nLong: " + longitude, Toast.LENGTH_LONG) .show(); } else { gps.showSettingsAlert(); } } }); 

但是我在下面得到错误::::

用这个:

  Geocoder geocoder = new Geocoder(this, Locale.getDefault()); List<Address> addresses = geocoder.getFromLocation(MyLat, MyLong, 1); String cityName = addresses.get(0).getAddressLine(0); String stateName = addresses.get(0).getAddressLine(1); String countryName = addresses.get(0).getAddressLine(2);

并为后台位置更新: http : //www.demoadda.com/demo/android/download-android-background-location-update-service-demo_21

在你的onClick添加这个:

 Geocoder gcd = new Geocoder(AndroidGPSTrackingActivity.this, Locale.getDefault()); List<Address> addresses = gcd.getFromLocation(latitude, longitude, 1); if (addresses.size() > 0) System.out.println(addresses.get(0).getLocality()); 
 gps = new LocationAddress(getActivity()); if (gps.canGetLocation()) { double latitude = gps.getLatitude(); double longitude = gps.getLongitude(); Geocoder geocoder = new Geocoder(getActivity(), Locale.getDefault()); //List<Address> addresses =geocoder.getFromLocation(latitude, longitude, 1); try { List < Address > addresses = geocoder.getFromLocation(latitude, longitude, 1); String address = addresses.get(0).getSubLocality(); String cityName = addresses.get(0).getLocality(); String stateName = addresses.get(0).getAdminArea(); txt_paddress.setText(address); txt_city.setText(cityName); txt_state.setText(stateName); } catch (IOException e) { e.printStackTrace(); } } else { gps.showSettingsAlert(); } 

使用地理编码器。 通过经纬度得到城市名称和地址。

 try { Geocoder geo = new Geocoder(this.getApplicationContext(), Locale.getDefault()); List < Address > addresses = geo.getFromLocation(latitude, longitude, 1); if (addresses.isEmpty()) { addres.setText("Waiting for Location"); } else { if (addresses.size() > 0) { addres.setText(addresses.get(0).getFeatureName() + ", " + addresses.get(0).getLocality() + ", " + addresses.get(0).getAdminArea() + ", " + addresses.get(0).getCountryName()); //Toast.makeText(getApplicationContext(), "Address:- " + addresses.get(0).getFeatureName() + addresses.get(0).getAdminArea() + addresses.get(0).getLocality(), Toast.LENGTH_LONG).show(); } } } catch (Exception e) { e.printStackTrace(); // getFromLocation() may sometimes fail } 

对于我的国家(越南) getLocality将返回null和addresses.get(0).getAddressLine(0)将返回区不城市

所以我会这样做

 Geocoder geocoder = new Geocoder(this, Locale.getDefault()); List<Address> addresses = geocoder.getFromLocation(latitude, longitude, 1); int maxAddressLine = addresses.get(0).getMaxAddressLineIndex(); String countryName = addresses.get(0).getAddressLine(maxAddressLine); String stateName = addresses.get(0).getAddressLine(maxAddressLine-1); String cityName = addresses.get(0).getAddressLine(maxAddressLine-2); 
 try { Geocoder geocoder = new Geocoder(this, Locale.getDefault()); List<Address> addresses = geocoder.getFromLocation(28.5839624000, 77.3154441000, 1); String addres = addresses.get(0).getSubLocality(); String cityName = addresses.get(0).getLocality(); String stateName = addresses.get(0).getAdminArea(); String getPostalCode = addresses.get(0).getPostalCode(); Log.e("keshav","addres -> "+addres); Log.e("keshav","cityName -> "+ cityName); Log.e("keshav","stateName -> "+ stateName); Log.e("keshav","PostalCode -> "+ getPostalCode); } catch (IOException e) { e.printStackTrace(); }
