repetition in the menu

Please help me out regarding repeating the menu.

First class:

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

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        MenuInflater inflater = getMenuInflater();
        inflater.inflate(R.menu.menu, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        switch (item.getItemId()) {
            case R.id.settings:     
                Intent intent = new Intent(this, ShowSettings.class);
                  startActivity(intent);
            break;
            case R.id.services:     
                Intent intent2 = new Intent(this, Test.class);
                startActivity(intent2);
              break;
            case R.id.Quit: 

                finish();



                break;
            default:    
            break;
        }
        return true;
    }
}

second class

public class Test extends ListActivity  {


            @Override
            public void onCreate(Bundle savedInstanceState) {
               over here i will be fetching the list from the server 
            }

            @Override
            public boolean onCreateOptionsMenu(Menu menu) {
                MenuInflater inflater = getMenuInflater();
                inflater.inflate(R.menu.menu, menu);
                return true;
            }

            @Override
            public boolean onOptionsItemSelected(MenuItem item) {
                switch (item.getItemId()) {
                    case R.id.settings:     
                        Intent intent = new Intent(this, ShowSettings.class);
                          startActivity(intent);
                    break;
                    case R.id.services:     
                        Intent intent2 = new Intent(this, Test.class);
                        startActivity(intent2);
                      break;
                    case R.id.Quit: 

                        finish();



                        break;
                    default:    
                    break;
                }
                return true;
            }
        }

I have tried in this way but it was not working.

instead of emulator when i tried to run on the android i got the following logcat

I have tried only the onCreateOptionsMenu method of the code provided in the link you have mentioned and it works.

From the code (still from the link, in the MenuHandler.java)

  public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
        case R.id.settings:     
            Intent intent = new Intent(this, ShowSettings.class);
              startActivity(intent);
        break;
        case R.id.services:     
            Intent intent2 = new Intent(this, Test.class);
            startActivity(intent2);
          break;
        case R.id.Quit: 

Make sure you call the new activity as

Intent intent = new Intent(activity, ShowSettings.class);
activity.startActivity(intent);

Same inside the case R.id.services
