registerForContextMenu not get calling properly - what am I doing wrong?

The answer to this question might be really obvious but its giving me a headache. I have a simple LinearLayout with one single ListView in it. I do this: onCreate

public void onCreate(Bundle b) {
        super.onCreate(b);
        setContentView(R.layout.friends);
        ListView listView = (ListView) findViewById(R.id.friend_list);
        listAdapter = new CheckinListAdapter(checkins, listView, R.layout.checkin_list_item);
        listView.setAdapter(listAdapter);

        if (getLastNonConfigurationInstance() != null) {
            FriendsActivity last = (FriendsActivity) getLastNonConfigurationInstance();
            this.checkins.addAll(last.checkins);
            this.sort = last.sort;
        } else {
            refresh();
        }
        registerForContextMenu(listView);
    }

But for some reason onCreateContextMenu never gets called! So I did some research and since I am loading the list after the register, perhaps it doesn't register it correctly. If I go in my ListAdapter and do registerForContextMenu it does show up. But it doesn't behave correctly with the keyboard. So I am now confused on what can be the error because it seems a little non intuitive for me to have to register each child item. All the examples I find online are using ArrayAdapter. :(

Any suggestions?

Edit

Here is more detail, in case it something I don't see:

This took me 6 hours to figure out but it turns out I had to add:

android:focusable="false"

to all my <Button/> tags.

Do, registerForContextMenu(listView); before setting the adapter, that is before:

listView.setAdapter(listAdapter);

You have mentioned that the menu is not responding correctly with the keyboard actions. Can you tell me what exactly the problem is?
