Change contextmenu text based on list item

Lets say I have a list of friends stored in a database and showed in a list in my activity. For this list, I have an context menu with "edit", "delete" and "bad friend/good friend". The case is that I would like to change the text of the last item in the menu ("bad friend/good friend") based on a value in the database. (Toggle the text).

If the friend is a good friend, the context menu text should be "not good friend" and if the friend is a bad friend, the text should be "good friend". This means that a click on this item in the context menu toggles the friends from good to bad or bad to good.

Any suggestions?

I use this approach.

Declare two activity fields:

private int listItemPressedPos;
private long listItemPressedId;

Declare an onItemLongClick event and use them to save position and id of listItem clicked 

myList.setOnItemLongClickListener(new OnItemLongClickListener() {

    @Override
    public boolean onItemLongClick(AdapterView<?> adapter, View v, int pos, long id) {

        listItemPressedPos = pos;
        listItemPressedId = id;
        return false;
    }
});

In onCreateContextMenu method get the row from database by Id and change the menu accordingly. 

@Override
public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo) {
    super.onCreateContextMenu(menu, v, menuInfo);

    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.dispositivos_list_context, menu);

    //Change this part accordingly your needs
    if(tbDispositivos.isSelected(listItemPressedId)){//get value from database
        //Alter the menuItem
        menu.findItem(R.id.dispositivosContextItemDelete).setVisible(false);
    }
}
