어떻게 불러야 IP를 받아올수 있나요? [코드있음]

Question

package com.example.iptest;

import java.net.InetAddress;
import java.net.NetworkInterface;
import java.net.SocketException;
import java.util.Enumeration;
import android.support.v7.app.ActionBarActivity;
import android.util.Log;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.TextView;

 

public class IpText<TextHandler> extends ActionBarActivity {
 
 private static final String DEBUG_TAG = null;

 public String getLocalIpAddress()
  {
   final String IP_NONE = "N/A";
   final String WIFI_DEVICE_PREFIX = "eth";
  
   String LocalIP = IP_NONE;
   try {
          for (Enumeration<NetworkInterface> en = NetworkInterface.getNetworkInterfaces();
            en.hasMoreElements();) {
              NetworkInterface intf = en.nextElement();          
              for (Enumeration<InetAddress> enumIpAddr = intf.getInetAddresses();
                enumIpAddr.hasMoreElements();) {
                  InetAddress inetAddress = enumIpAddr.nextElement();
                  if (!inetAddress.isLoopbackAddress()) {
                   if( LocalIP.equals(IP_NONE) )
                      LocalIP = inetAddress.getHostAddress().toString();
                   else if( intf.getName().startsWith(WIFI_DEVICE_PREFIX) )
                      LocalIP = inetAddress.getHostAddress().toString();
                  }
              }
          }
      } catch (SocketException e) {
          Log.e(DEBUG_TAG, "getLocalIpAddress Exception:"+e.toString());
      }
      return LocalIP;
  }

 @Override
 public boolean onCreateOptionsMenu(Menu menu) {
  // Inflate the menu; this adds items to the action bar if it is present.
  getMenuInflater().inflate(R.menu.ip_text, menu);
  
  setContentView(R.layout.mrchu);
  TextView Ipttext = (TextView)findViewById(R.id.Ipttext);
  Ipttext.setVisibility(View.VISIBLE);
  Ipttext.setText("LocalIP");
  
  
  return true;
 }

 @Override
 public boolean onOptionsItemSelected(MenuItem item) {
  // Handle action bar item clicks here. The action bar will
  // automatically handle clicks on the Home/Up button, so long
  // as you specify a parent activity in AndroidManifest.xml.
  int id = item.getItemId();
  if (id == R.id.action_settings) {
   return true;
  }
  return super.onOptionsItemSelected(item);
 }
}

 

 

IP를 불러온다는 코드로 하여금 하고 Settext로 하여 IP를 보내서 출력하는 방법이 가능한건가요??

IP를 저기에 넣어야 하는데.. 어디에 뭘추가해야 될까요?

스레드 사용해서 보내야할 것 같은데...;;
