menu example

I got one to work .

when does this code run because there is no call to this. Is it when you hit menu on the emulator?
 
@Override
    public boolean onCreateOptionsMenu(Menu menu) {
        MenuInflater inflater = getMenuInflater();
        inflater.inflate(R.menu.menu, menu);
        return true;
    }

http://developer.android.com/guide/topics/ui/menus.html

To specify the options menu for an activity, override onCreateOptionsMenu() (fragments provide their own onCreateOptionsMenu() callback). In this method, you can inflate your menu resource (defined in XML) into the Menu provided in the callback. For example:
(here exactly the same code as yours quoted above)

If you've developed your application for Android 2.3.x and lower, the system calls onCreateOptionsMenu() to create the options menu when the user opens the menu for the first time. If you've developed for Android 3.0 and higher, the system calls onCreateOptionsMenu() when starting the activity, in order to show items to the action bar.

Thanks for the information.

Yes, AdapterView.OnItemCLickListener - it locates and imports both these types for me based on that code which you pointed to
