ListView displays data from last passes as well as current pas

Question

I have a small "search" implementation I am working on. A listView displays the items if they match the query. This works fine, but whenever the menu is hidden and re-displayed and a new query is made, all the "searchables" continue to stack up. If i have 4 that should be displaying, first it would show 4, then 8, then 12, etc.

private class Adapter extends BaseAdapter {

    private LayoutInflater inflater;

    public Adapter(){
        inflater = LayoutInflater.from(getContext());
    }

    @Override
    public int getCount() {
        return menuItems.size();
    }

    @Override
    public Object getItem(int position) {
        return menuItems.get(position).text;
    }

    @Override
    public long getItemId(int position) {
        return menuItems.get(position).id;
    }

    @Override

            } else {
                convertView = inflater.inflate(R.layout.rbm_search_item, null);
