Connect to network from listview

Question

See my code below. This produces a listview with all available wificonnections. My goal is too connect to one of those available connections listed. I have tried several things but it won't work properly. It's about filling the onclick property for the listview with the right code. Can anybody help me out? Thanks in advance!

   public class Main extends Activity implements OnClickListener
 {      
     WifiManager wifi;       
    ListView lv;
    TextView textStatus;
    Button buttonScan;
    int size = 0;
    List<ScanResult> results;

    String ITEM_KEY = "key";
    ArrayList<HashMap<String, String>> arraylist = new ArrayList<HashMap<String,       String>>();
SimpleAdapter adapter;

/* Called when the activity is first created. */
@Override

    textStatus = (TextView) findViewById(R.id.textStatus);

        {
            //Method to connect to the listview item
        }

    });

    wifi = (WifiManager) getSystemService(Context.WIFI_SERVICE);
    if (wifi.isWifiEnabled() == false)

           size = results.size();
        }
    }, new IntentFilter(WifiManager.SCAN_RESULTS_AVAILABLE_ACTION));                    
}



public void onClick(View view) 
{
    arraylist.clear();          
    wifi.startScan();

    Toast.makeText(this, "Scanning...." + size, Toast.LENGTH_SHORT).show();
    try 
    {
        size = size - 1;
        while (size >= 0)

            item.put(ITEM_KEY, results.get(size).SSID + "  " + results.get(size).capabilities);

            arraylist.add(item);
            size--;
            adapter.notifyDataSetChanged();                 
        } 
    }
    catch (Exception e)
    { }         
}    
 }

Try this

@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
        long arg3) 
{
    connectToWifi(arg2);
}

private void connectToWifi(int position)
{
    HashMap<String, String> item = arraylist.get(position);

    //get SSID and BSSID from item

    WifiConfiguration wifiConfiguration = new WifiConfiguration(); 
    wifiConfiguration.SSID = itemSSID; 
    wifiConfiguration.allowedKeyManagement.set(KeyMgmt.NONE); 
    wifiConfiguration.BSSID = itemBSSID; //you should also put the BSSID in the map
    wifiConfiguration.hiddenSSID = false; 

    int inetId = wifiManager.addNetwork(wifiConfiguration); 
    wifiManager.enableNetwork(inetId, true);
}
