Ich möchte Longitude und Latitude getrennt von einer bestimmten Adresse abrufen

Question

Ich folgte einem Beispiel von Android Geocoding, um Längengrad für eine Adresse Lernprogramm zu erhalten, es funktionierte, aber ich möchte die Längen- und Breitengradkoordinaten getrennt abrufen, konnte aber nicht.

Hier ist mein Code:

public class MainActivity extends AppCompatActivity { 
    Button addressButton; 
    TextView addressTV; 
    TextView latLongTV; 
    static TextView txtLatitude; 
    TextView txtLongitude; 


    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 


     addressTV = (TextView) findViewById(R.id.addressTV); 
     latLongTV = (TextView) findViewById(R.id.latLongTV); 
    txtLatitude = (TextView) findViewById(R.id.txtLatitude); 
     txtLatitude= (TextView) findViewById(R.id.txtLongitude); 

     addressButton = (Button) findViewById(R.id.addressButton); 
     addressButton.setOnClickListener(new View.OnClickListener() { 

      @Override 
      public void onClick(View arg0) { 

       EditText editText = (EditText) findViewById(R.id.addressET); 
       String address = editText.getText().toString(); 

       GeocodingLocation locationAddress = new GeocodingLocation(); 
       locationAddress.getAddressFromLocation(address, 
         getApplicationContext(), new GeocoderHandler()); 
      } 
     }); 

    } 

    private class GeocoderHandler extends Handler { 
     @Override 
     public void handleMessage(Message message) { 
      String locationAddress,latitude ,longitude ; 

      switch (message.what) { 
       case 1: 
        Bundle bundle = message.getData(); 
        locationAddress = bundle.getString("address"); 
        latitude = bundle.getString("latitude"); 
        longitude = bundle.getString("longitude"); 
        break; 
       default: 
        locationAddress = null; 
        latitude = null; 
        longitude= null; 
      } 
      latLongTV.setText(locationAddress); 
      txtLatitude.setText(latitude); 
//  txtLongitude.setText(longitude); 
     } 
    } 

    private static class GeocodingLocation { 


      private static final String TAG = "GeocodingLocation"; 

      public void getAddressFromLocation(final String locationAddress, 
               final Context context, final Handler handler) { 
       Thread thread = new Thread() { 
        @Override 
        public void run() { 
         Geocoder geocoder = new Geocoder(context, Locale.getDefault()); 
         String result = null; 
         String strLatitude = null, strLongitude = null; 
         try { 
          List<Address> addressList = geocoder.getFromLocationName(locationAddress, 1); 
          if (addressList != null && addressList.size() > 0) { 
           Address address = addressList.get(0); 
           double latitude = address.getLatitude(); 
           double longitude = address.getLongitude(); 
           StringBuilder sb = new StringBuilder(); 
           sb.append(address.getLatitude()).append("\n"); 
           sb.append(address.getLongitude()).append("\n"); 
           result = sb.toString(); 
           strLatitude = String.valueOf(latitude); 
           strLongitude= String.valueOf(longitude); 
          } 
         } catch (IOException e) { 
          Log.e(TAG, "Unable to connect to Geocoder", e); 
         } finally { 
          Message message = Message.obtain(); 
          message.setTarget(handler); 
          if (result != null) { 
           message.what = 1; 
           Bundle bundle = new Bundle(); 
           result = "Address: " + locationAddress + 
             "\n\nLatitude and Longitude :\n" + result; 
           bundle.putString("address", result); 
           bundle.putString("Latitude", strLatitude); 
           bundle.putString("Longitude", strLongitude); 
           message.setData(bundle); 
          } else { 
           message.what = 1; 
           Bundle bundle = new Bundle(); 
           result = "Address: " + locationAddress + 
             "\n Unable to get Latitude and Longitude for this address location."; 
           bundle.putString("address", result); 
           message.setData(bundle); 
          } 
          message.sendToTarget(); 
         } 
        } 
       }; 
       thread.start(); 
      } 
     }

Nach this answer, Bündel Tasten sind case-sensitive. Sie setzen die Saiten mit:

bundle.putString("Latitude", strLatitude); 
bundle.putString("Longitude", strLongitude); 

Aber dann kommen sie mit:

latitude = bundle.getString("latitude"); 
longitude = bundle.getString("longitude"); 

Hinweis Sie mit einem Kapital setzen L, aber mit einem Klein l bekommen.
