menu won't show up android

Question

Hi i'm trying to show the menu when the user presses the menu button. I'm using the code from the Documentation but the options menu won't show up. I guess i should have a listener for this menu button, but how?? This is my class so far:

    public class AppMenu extends Activity {

 @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.about);
    }

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

 @Override
 public boolean onOptionsItemSelected(MenuItem item) {
     // Handle item selection
     switch (item.getItemId()) {
     case R.id.hello:
         sayHello();
         return true;
     case R.id.bye:
      finish();
         return true;

     default:
         return super.onOptionsItemSelected(item);
     }
 }
}

Here is my xml file

    <?xml version="1.0" encoding="UTF-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:id="@+id/hello"
          android:title="Hello" 
          android:icon="@drawable/icon"/>
    <item android:id="@+id/bye"
          android:title="Bye" />
</menu>

Thanks !

Now it's working as it is supposed to work. I just implemented this: link text thanks for the patience.

This answer is in response to the comment discussion on the question.

You can't have to menu appear outside of your Activity . That means you have to start your Activity and then from inside your Activity you'll be able to get the menu appear on a menu button press.
