I have this bit of code and I am trying to get it working ... can you help me with the issues I have? which is to do with the R.layout... also point out any tips or hints on where to improve? I am just playing around at the moment getting used to it


package com.example.webu;

import java.util.ArrayList;

import java.util.HashMap;

import java.util.List;

import android.os.Bundle;

import android.app.Activity;

import android.content.Context;

import android.view.Menu;

import android.widget.ListView;

import android.widget.SimpleAdapter;

import android.widget.TextView;

import android.net.ConnectivityManager;

import android.net.NetworkInfo;

import android.net.wifi.ScanResult;

import android.net.wifi.WifiManager;

public class MainActivity extends Activity {

SimpleAdapter adapter;

ArrayList<HashMap<String, String>> arraylist = new ArrayList<HashMap<String, String>>();

@Override

protected void onCreate(Bundle savedInstanceState) {

  super.onCreate(savedInstanceState);

  setContentView(R.layout.activity_main);


  ConnectivityManager cm = (ConnectivityManager) getSystemService(CONNECTIVITY_SERVICE);

  NetworkInfo at = cm.getActiveNetworkInfo();


  final TextView tni = (TextView)findViewById(R.id.textView1);

  ListView lv = (ListView)findViewById(R.id.listView1);



  WifiManager wifi = (WifiManager) getSystemService(Context.WIFI_SERVICE);

  if(wifi.isWifiEnabled()) {

    List<ScanResult> scanResults = wifi.getScanResults();

    for(ScanResult scanRes : scanResults) {

		 this.adapter = new SimpleAdapter(MainActivity.this, arraylist, R.layout.rowLayout, new String[] { ITEM_KEY }, new int[] { R.id.list_value });

		  lv.setAdapter(this.adapter);

	 //tni.setText(scanRes.toString());

    }

  }

  //tni.setText(at.toString());

}

@Override

public boolean onCreateOptionsMenu(Menu menu) {

  // Inflate the menu; this adds items to the action bar if it is present.

  getMenuInflater().inflate(R.menu.activity_main, menu);

  return true;

}

}
