Body
copied!<p>Actually i am using geocoder to get the address..but i am getting address value as null.According to me I wrote the correct code to get current location from methods like getAddress() and address().The code i used is as following:</p> <pre><code>public class CurrentLoc extends Activity { // latitude and longitude static double latitude ; static double longitude ; // Google Map private GoogleMap googleMap; private LocationManager locationManager; private Location location; private String val; private static final long MINIMUM_DISTANCE_CHANGE_FOR_UPDATES = 1; // in Meters private static final long MINIMUM_TIME_BETWEEN_UPDATES = 1000; // in Milliseconds @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.new3); locationManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE); locationManager.requestLocationUpdates( LocationManager.GPS_PROVIDER, MINIMUM_TIME_BETWEEN_UPDATES, MINIMUM_DISTANCE_CHANGE_FOR_UPDATES, new MyLocationListener() ); locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, MINIMUM_TIME_BETWEEN_UPDATES, MINIMUM_DISTANCE_CHANGE_FOR_UPDATES, new MyLocationListener()); getAddress(); try { // Loading map initilizeMap(); } catch (Exception e) { e.printStackTrace(); } } /** * function to load map. If map is not created it will create it for you * */ public String getAddress(){ location = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER); location = locationManager.getLastKnownLocation(locationManager.NETWORK_PROVIDER); if (location != null) { latitude= location.getLatitude(); longitude= location.getLongitude(); /*String message = String.format( "Current Location \n Longitude: %1$s \n Latitude: %2$s", lat, lng);*/ try { val = address(latitude, longitude); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } Toast.makeText( CurrentLoc.this, val, Toast.LENGTH_LONG).show(); } return val; } public String address(double lt,double lg) throws IOException{ Geocoder geocoder; List<Address> addresses; geocoder = new Geocoder(this, Locale.getDefault()); addresses = geocoder.getFromLocation(lt, lg, 1); String address = addresses.get(0).getAddressLine(0); String city = addresses.get(0).getAddressLine(1); String country = addresses.get(0).getAddressLine(2); return address +"\n"+ city +"\n"+ country; } private class MyLocationListener implements LocationListener { public void onLocationChanged(Location location) { String message = String.format( "New Location \n Longitude: %1$s \n Latitude: %2$s", location.getLongitude(), location.getLatitude() ); // Toast.makeText(MainActivity.this, message, Toast.LENGTH_LONG).show(); } public void onStatusChanged(String s, int i, Bundle b) { Toast.makeText(CurrentLoc.this, "Provider status changed", Toast.LENGTH_LONG).show(); } public void onProviderDisabled(String s) { Toast.makeText(CurrentLoc.this, "Provider disabled by the user. GPS turned off", Toast.LENGTH_LONG).show(); } public void onProviderEnabled(String s) { Toast.makeText(CurrentLoc.this, "Provider enabled by the user. GPS turned on", Toast.LENGTH_LONG).show(); } } private void initilizeMap() { if (googleMap == null) { googleMap = ((MapFragment) getFragmentManager().findFragmentById( R.id.map)).getMap(); CameraPosition cameraPosition = new CameraPosition.Builder().target( new LatLng(location.getLatitude(), location.getLongitude())).zoom(12).build(); googleMap.animateCamera(CameraUpdateFactory.newCameraPosition(cameraPosition)); MarkerOptions marker = new MarkerOptions().position(new LatLng(location.getLatitude(), location.getLongitude())).title("Hello Maps "); googleMap.addMarker(marker); googleMap.isMyLocationEnabled(); // check if map is created successfully or not if (googleMap == null) { Toast.makeText(getApplicationContext(), "Sorry! unable to create maps", Toast.LENGTH_SHORT) .show(); } } } @Override public boolean onCreateOptionsMenu(Menu menu) { MenuInflater inflater = getMenuInflater(); inflater.inflate(R.menu.mnew1, menu); return super.onCreateOptionsMenu(menu); } @Override public boolean onOptionsItemSelected(MenuItem item) { // Handle presses on the action bar items switch (item.getItemId()) { case R.id.home: openSearch(); return true; default: return super.onOptionsItemSelected(item); } } private void openSearch(){ String val1 = null; val1 = getAddress(); Intent intnt=new Intent(getApplicationContext(),SendSms.class); intnt.putExtra("loct", val1); startActivity(intnt); } </code></pre> <p>}</p>
