如何在基本适配器中按下按钮时添加新项

public class CustomAdapter extends BaseAdapter {
    private List<String> data;

    public CustomAdapter(List<String> data) {
        this.data = data;
    }

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

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

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

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        if (convertView == null) {
            LayoutInflater inflater = LayoutInflater.from(parent.getContext());
            convertView = inflater.inflate(R.layout.list_item, parent, false);
        }

        TextView textView = convertView.findViewById(R.id.text_view);
        Button button = convertView.findViewById(R.id.button);

        String item = data.get(position);
        textView.setText(item);

        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                // 添加新项到数据源
                data.add("New Item");
                notifyDataSetChanged(); // 通知适配器数据源已更改
            }
        });

        return convertView;
    }
}
