How to disable list view item based on string value?

Question

I am creating an application that pulls data from a firebase database and presents it to the user in a custom listview. I want to make it so that in a list item, if the textview contains the word "Unavailable", the user shouldn't be unable to select that list item. How can I achieve this dynamically ?

Java Code:

    @Override
    public void onStart()
    {
        super.onStart();

        Query query = FirebaseDatabase.getInstance().getReference().child("TimeSlots").orderByChild("id");
        FirebaseListOptions<BookingTimes> options = new FirebaseListOptions.Builder<BookingTimes>()
                .setLayout(R.layout.time_list_layout_adapter)
                .setLifecycleOwner(getActivity())
                .setQuery(query, BookingTimes.class)
                .build();
        adapter = new FirebaseListAdapter(options)
        {
            @Override
            protected void populateView(View v, Object model, int position)
            {
                timeTextV = v.findViewById(R.id.timeTV);
                availabilityTextv = v.findViewById(R.id.availabilityTV);

                BookingTimes bookingTimes = (BookingTimes) model;
                timeTextV.setText(bookingTimes.getTime());
                availabilityTextv.setText(bookingTimes.getAvailability());

                /*if (availabilityTextv.getText().toString().equals("Unavailable"))
                {
                    availabilityTextv.setEnabled(false);
                }*/ //<==== doesn't work
            }

            @Override
            public boolean areAllItemsEnabled()
            {
                return false;
            }

            @Override
            public boolean isEnabled(int position)
            {
                /*if(position == 3)
                {
                    return false;
                } //<== this works, but how do i do it dynamically based on value?*/
                /*if(availabilityTextv.getText().toString().equals("Unavailable"))
                {
                    getItem(position);
                    return false;
                }*/ //<== doesn't work
                return super.isEnabled(position);
            }
        };

        listView.setAdapter(adapter);

BookingTimes class:

    private String availability;

    public BookingTimes()
    {

    }

    public BookingTimes(String Time, String Availability)
    {
        this.time = Time;
        this.availability = Availability;
    }

    public String getTime()
    {
        return time;
    }

    public void setTime(String Time)
    {
        this.time = Time;
    }

    public String getAvailability()

        return availability;

    public void setAvailability(String Availability)
    {
        this.availability = Availability;
    }
}

You'd have to use the item availability directly in isEnabled(int).

new FirebaseListAdapter<BookingTimes>(options)
{
    ...

    @Override
    public boolean isEnabled(int position)
    {
        return getItem(position).getAvailability().equals("Unavailable");
    }
}

Also keep in mind that FirebaseListAdapter has a generic parameter type. Also make sure to not views like timeTextV or availabilityTextv, preferably with the view holder pattern.
