android - Android ListView から複数のアイテムを削除する

Question

以下のコードを使用してリストビューから複数の行を削除するにはどうすればよいですか。私は MultiChoiceModeListener を使用しています。

主な活動

list.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE_MODAL);
        list.setMultiChoiceModeListener(new MultiChoiceModeListener() {

            @Override
            public void onItemCheckedStateChanged(ActionMode mode,
                    int position, long id, boolean checked) {
                // Here you can do something when items are selected/de-selected
                final int checkedCount = list.getCheckedItemCount();
                // Update the title in the CAB
                mode.setTitle(checkedCount + " Selected");

            }
    @Override
            public boolean onActionItemClicked(ActionMode mode, MenuItem item) {
                switch (item.getItemId()) {
                case R.id.menu_clear:
                    deleteSelectedItems(item.getItemId());
                    mode.finish();
                    return true;
                default:
                    return false;
                }
            }
            public void deleteSelectedItems(int id) {
                adapter.remove(adapter.getItem(id)); //The method remove(Object) is undefined for the type ListViewAdapter
            }

ListViewAdapter

public class ListViewAdapter extends BaseAdapter {

    // Declare Variables
    Context context;
    String[] rank;
    String[] country;
    String[] population;
    LayoutInflater inflater;
    View itemView;

    public ListViewAdapter(Context context, String[] rank, String[] country,
            String[] population) {
        this.context = context;
        this.rank = rank;
        this.country = country;
        this.population = population;
    }

    @Override
    public int getCount() {
        return rank.length;
    }

    @Override
    public Object getItem(int position) {
        return null;
    }

    @Override
    public long getItemId(int position) {
        return 0;
    }

    public View getView(int position, View convertView, ViewGroup parent) {

        // Declare Variables
        TextView txtrank;
        TextView txtcountry;
        TextView txtpopulation;

        inflater = (LayoutInflater) context
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);

        itemView = inflater.inflate(R.layout.listview_item, parent, false);


        txtrank = (TextView) itemView.findViewById(R.id.rank);
        txtcountry = (TextView) itemView.findViewById(R.id.country);
        txtpopulation = (TextView) itemView.findViewById(R.id.population);


        txtrank.setText(rank[position]);
        txtcountry.setText(country[position]);
        txtpopulation.setText(population[position]);

        return itemView;
    }
