import java.io.IOException;
import java.util.List;
import java.util.Locale;

import com.google.android.gms.maps.GoogleMap;
 import ie.wit.mybook.*;
import android.app.Activity;
  import android.location.Address;
  import android.location.Geocoder;
      import android.os.Bundle;
    import android.widget.TextView;
   import android.widget.Toast;

    public class AdressGet extends Activity {

    double LATITUDE=52.7;
    double LONGITUDE=-7.12;
    GPSHelper mylo;
   /** Called when the activity is first created. */
   @Override
   public void onCreate(Bundle savedInstanceState) {
   super.onCreate(savedInstanceState);
   setContentView(R.layout.adressget);
   TextView myLatitude = (TextView)findViewById(R.id.mylatitude);
   TextView myLongitude = (TextView)findViewById(R.id.mylongitude);
   TextView myAddress = (TextView)findViewById(R.id.myaddress);

   myLatitude.setText("Latitude: " + String.valueOf(LATITUDE));
   myLongitude.setText("Longitude: " + String.valueOf(LONGITUDE));

   Geocoder geocoder = new Geocoder(this, Locale.ENGLISH);

   try {
   List<Address> addresses = geocoder.getFromLocation(LATITUDE, LONGITUDE, 1);

  if(addresses != null) {
    Address returnedAddress = addresses.get(0);
   StringBuilder strReturnedAddress = new StringBuilder("Address:\n");
   for(int i=0; i<returnedAddress.getMaxAddressLineIndex(); i++) {
    strReturnedAddress.append(returnedAddress.getAddressLine(i)).append("\n");
   }
    myAddress.setText(strReturnedAddress.toString());
  }
  else{
   myAddress.setText("No Address returned!");
  }
 } catch (IOException e) {
  // TODO Auto-generated catch block
  e.printStackTrace();
  myAddress.setText("Canont get Address!");
}

  }
}

如果需要获取真实坐标，则需要使用LocationListener。试试这个:http://www.vogella.com/tutorials/AndroidLocationAPI/article.html
