List view under tab

package com.example.helloandroid;

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

import android.app.TabActivity;
import android.os.Bundle;
import android.view.Window;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.TabHost;

public class HelloAndroid extends TabActivity {
/** Called when the activity is first created. */
private ListView mainListView ;  
private ArrayAdapter<String> listAdapter ;
@Override


public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    setContentView(R.layout.main);

    TabHost mTabHost = getTabHost();

    mTabHost.addTab(mTabHost.newTabSpec("tab_test1").setIndicator("TAB 1"));
    mTabHost.addTab(mTabHost.newTabSpec("tab_test2").setIndicator("TAB 2"));
    mTabHost.addTab(mTabHost.newTabSpec("tab_test3").setIndicator("TAB 3"));

    mTabHost.setCurrentTab(0);

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

    // Create and populate a List of planet names.  
    String[] planets = new String[] { "Mercury", "Venus", "Earth", "Mars",  
                                      "Jupiter", "Saturn", "Uranus", "Neptune"};    
    ArrayList<String> planetList = new ArrayList<String>();  
    planetList.addAll( Arrays.asList(planets) );  

    // Create ArrayAdapter using the planet list.  
   listAdapter = new ArrayAdapter<String>(this, R.layout.main, planetList);  

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


 // End


}

}

and here is the code for my xml file.

<?xml version="1.0" encoding="utf-8"?>
