Main Layout File

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">

<ListView android:layout_width="fill_parent" 
  android:layout_height="fill_parent" 
  android:id="@+id/mainListView">
</ListView>

Activity File

package com.example.android;

import java.util.ArrayList;
import java.util.Arrays;

import android.app.Activity;
import android.os.Bundle;
import android.widget.ArrayAdapter;
import android.widget.ListView;

public class SimpleListViewActivity extends Activity {

private ListView mainListView ;
private ArrayAdapter<String> listAdapter ;

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);

// Find the ListView resource. 
mainListView = (ListView) findViewById( R.id.mainListView );

// Create and populate a List of context names.
String[] context = new String[] { "context1", "context2", "context3", "context4","context5"};  
ArrayList<String> context = new ArrayList<String>();
contextList.addAll( Arrays.asList(context) );

// Create ArrayAdapter using the context list.
listAdapter = new ArrayAdapter<String>(this, R.layout.simplerow, contextList);

// Add more contexts. If you passed a String[] instead of a List<String> 
// into the ArrayAdapter constructor, you must not add more items. 
// Otherwise an exception will occur.
listAdapter.add( "context8" );
listAdapter.add( "context9" );
listAdapter.add( "context10" );

// Set the ArrayAdapter as the ListView's adapter.
mainListView.setAdapter( listAdapter );      
}
}
