Spinner with custom adapter show the selected item Android

Question

in my program use a spinner with a custom adapter. The adapter is:

private class lenguageSpinnerAdapter extends BaseAdapter implements
        SpinnerAdapter {

    private ArrayList<String> lenguages;

    public lenguageSpinnerAdapter(Context context,
            ArrayList<String> lenguages) {
        this.lenguages = lenguages;
    }

    public int getCount() {
        return lenguages.size();
    }

    public Object getItem(int position) {
        return lenguages.get(position);
    }

    public long getItemId(int position) {
        return position;
    }

    public View getView(int position, View convertView, ViewGroup parent) {
        if (convertView == null) {
            // This a new view we inflate the new layout
            LayoutInflater inflater = (LayoutInflater) context
                    .getApplicationContext().getSystemService(
                            Context.LAYOUT_INFLATER_SERVICE);
            convertView = inflater.inflate(R.layout.lenguage_item_layout,
                    parent, false);
        }

        TextView lenguage = (TextView) convertView
                .findViewById(R.id.textViewLenguage);
        lenguage.setText(lenguages.get(position).toString());


        return convertView;
    }

}

And I use this adapter in an Activity:

ArrayList<String> spinnerArray = new ArrayList<String>();
    spinnerArray.add("IT");
    spinnerArray.add("EN");
    spinnerArray.add("PR");

    final lenguageSpinnerAdapter lenguageAdapter = new lenguageSpinnerAdapter(
            getContext(), spinnerArray);
    spinnerLenguage.setAdapter(lenguageAdapter);

The problem is that this spinner show always the three lenguages, but I would like him to show only the not selected lenguages (EN and PR if IT il selected, or IT and PR if EN in selected). Any ideas?

    spinnerLenguage.setOnItemSelectedListener(new OnItemSelectedListener() {

        @Override
        public void onItemSelected(AdapterView<?> arg0, View arg1,
                int position, long arg3) {

            // Build your new array
            // Build your new adapter
            // Set your new adapter to spinnerLenguage

        }

        @Override
        public void onNothingSelected(AdapterView<?> arg0) {
            // TODO Auto-generated method stub

        }
    });
