TextView mainText; 
WifiManager mainWifi; 
WifiReceiver receiverWifi; 
List<ScanResult> wifiList; 
StringBuilder sb = new StringBuilder(); 

public void onCreate(Bundle savedInstanceState) 
{ 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.main); 
    mainText = (TextView) findViewById(R.id.mainText); 
    mainWifi = (WifiManager) getSystemService(Context.WIFI_SERVICE); 
    receiverWifi = new WifiReceiver(); 
    registerReceiver(receiverWifi, new IntentFilter(
    WifiManager.SCAN_RESULTS_AVAILABLE_ACTION)); 
    mainWifi.startScan();

    public void onReceive(Context c, Intent intent) { 
    sb = new StringBuilder(); 
    wifiList = mainWifi.getScanResults(); 
    for(int i = 0; i < wifiList.size(); i++){ 
    sb.append(new Integer(i+1).toString() + "."); 
    sb.append((wifiList.get(i)).toString()); 
    sb.append("\n"); 
} 
mainText.setText(sb);
