使用

                .bindClick(ResourceTable.Id_item_notice_root, (pos, data) -> {
                    Notice notice = (Notice)data;
                    Router.toSimpleAbility(getFractionAbility(),NoticeDetailSlice.class,
                            MapUtil.mapObj().puts(NoticeDetailSlice.ID,notice.id));

                })
                .vertical(noticeList);

在具体的ViewHolder中绑定

public class NoticeHolder extends ViewHolder<Notice> {

    private Image imgView;
    private Component rootView;
    private Text titleView,contentView;

    public NoticeHolder(Context context) {
        super(context);
    }

    @Override
    public void convert(Notice notice, int position) {
        titleView.setText(notice.title);
        contentView.setText(notice.description);
        bindClick(rootView);  //这一定必须!!!
    }
