Can I change the Icon on an Actionbar Item

I'm not trying to change the main Icon , just a menu item's icon.

The Icon is essentially displays whether I am recording at that moment. I change the icon when it's tapped using

item.setIcon(R.drawable.recordstart);

In this method.

public boolean onOptionsItemSelected(MenuItem item) {
    ...
    } else if (item.getItemId() == R.id.ab_menu_VRecord) {

        if(recording)
                    {
                       item.setIcon(R.drawable.recordstop);
                    }else{
                       item.setIcon(R.drawable.recordstart);
                    }

        }

        return true;
    } else {
        return super.onOptionsItemSelected(item);
    }
}

Anyone know how I can do this outside this method.

Example:

class {

    public MenuItem example;

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

Then throughout your class you can use 

example.setIcon("Your Image");

if(!item.isChecked()){
    item.setChecked(true);
    item.setIcon(R.drawable.icon1);
}else{
    item.setChecked(false);
    item.setIcon(R.drawable.icon2);
}

is this?

Not 100% sure where you are wanting to change the icon, but you can certainly cache or create a class member variable and point it at the the MenuItem in your Activity or Fragment for example. After they click it or you inflate it, assign it to the member variable and when you need to change it, you've got a reference or "cached" pointer to it to change the icon.

I think that is a UI change so you might have to be sure that you only call that on the UI thread.
