如何在android中移除listview中checkbox的焦点

public class MyAdapter extends ArrayAdapter<String> {
    private Context mContext;
    private List<String> mData;

    public MyAdapter(Context context, List<String> data) {
        super(context, R.layout.list_item, data);
        mContext = context;
        mData = data;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        ViewHolder holder;

        if (convertView == null) {
            convertView = LayoutInflater.from(mContext).inflate(R.layout.list_item, parent, false);
            holder = new ViewHolder();
            holder.checkBox = convertView.findViewById(R.id.checkbox);
            convertView.setTag(holder);
        } else {
            holder = (ViewHolder) convertView.getTag();
        }

        // 设置CheckBox的Selector
        holder.checkBox.setButtonDrawable(android.R.drawable.checkbox_off_background);

        // 设置CheckBox的状态
        holder.checkBox.setChecked(false);

        // 设置CheckBox的点击事件
        holder.checkBox.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                // 处理CheckBox的点击事件
            }
        });

        return convertView;
    }

    private static class ViewHolder {
        CheckBox checkBox;
    }
}
