Wifi scanning_collecting the samples

Samples: Reset

<- ->
Start Stop Save



Hiii...The interface is something like above but in the form of a square box with appropriate rows and columns.I couldnt attach the image of it.So somehow i just managed to draw it like this.

This is the calibration part for android. In which start, stop, save and reset are the buttons. The backward and forward arrows are for adjusting the points. And the samples will get collected in that very box as mentioned above. So far i have done this much coding though incomplete. Can someone please help me out.

AND FOR WIFI as follows:

package peopleTracking;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;

import android.R;
import android.net.wifi.ScanResult;
import android.net.wifi.WifiManager;

import android.view.View.OnClickListener;
import android.widget.Button;

import android.widget.SimpleAdapter;
import android.widget.TextView;
import android.widget.Toast;

public class peopleTracking 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;

public void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub

super.onCreate(savedInstanceState);
setContentView(R.layout.main);

textStatus = (TextView) findViewById(R.id.textStatus);
buttonScan = (Button) findViewById(R.id.startButton);
buttonScan.setOnClickListener((OnClickListener) this);
lv = (ListView)findViewById(R.id.list);

wifi = (WifiManager) getSystemService(Context.WIFI_SERVICE);
if (wifi.isWifiEnabled() == false)
{
Toast.makeText(getApplicationContext(), "wifi is disabled..making it enabled", Toast.LENGTH_LONG).show();
wifi.setWifiEnabled(true);
}
this.adapter = new SimpleAdapter(WiFiDemo.this, arraylist, R.layout.row, new String[] { ITEM_KEY }, new int[] { R.id.list_value });
lv.setAdapter(this.adapter);

registerReceiver(new BroadcastReceiver()
{
@Override
public void onReceive(Context c, Intent intent)
{
results = wifi.getScanResults();
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)
{
HashMap<String, String> item = new HashMap<String, String>();
item.put(ITEM_KEY, results.get(size).SSID + " " + results.get(size).capabilities);

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

}
