Question

So, I was reading this earlier question for ideas on how to allow me to click an item in a list to do one action or long-press that item to switch to an ActionMode where I can select multiple items and use the ActionBar to do something to those items. However, I’m having issues with this answer. Specifically, I’m implementing this into a SherlockListFragment (using ActionBarSherlock). However, the moment I declare a new MultiChoiceModeListener, Eclipse throw up a couple of compile errors.

Description Resource    Path    Location    Type
Cannot override the final method from SherlockListFragment  DateTimeListFragment.java   /path/to/my/project line 127    Java Problem
The method inflate(int, Menu) in the type MenuInflater is not applicable for the arguments (int, Menu)  DateTimeListFragment.java   /path/to/my/project line 125    Java Problem

These go away the moment I remove the MultiChoiceModeListener. I have no idea what could be causing it, as there’s nothing odd going on that I’m aware of.

public void onCreateOptionsMenu(Menu menu, MenuInflater inflater)
    {
        //super.onCreateOptionsMenu(menu, inflater);
        inflater.inflate(R.menu.alarmsmenu, menu); //line 125
    }
    public boolean onOptionsItemSelected(MenuItem Item) //line 127
    {
        switch(Item.getItemId())
        {
        case R.id.addAlarm:
            addAlarm();
            return true;
        case R.id.editAlarms:
            return true;
        default:
            return super.onOptionsItemSelected(Item);
        }       
    }

I’m very confused. Why does implementing MultiChoiceModeListener mean I can’t override OnOptionsItemSelected?

As a kind person from reddit has notified me, apparently ActionBarSherlock does not currently support MultiChoiceModeListener. The fact that I’m using ActionBarSherlock’s menus when the listener wants native Android menus probably contributes to the issue as well.
