实体类：ItemBean

public class ItemBean {

    private boolean isChecked; // 是否选中CheckBox

    public String getMsg() {

    }

    @Override

    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
    
    
        ViewHolder holder;
        if (convertView == null) {
    
    
            holder = new ViewHolder();
            convertView = inflater.inflate(R.layout.item, null);
            holder.msg = (TextView) convertView.findViewById(R.id.listview_tv);
            holder.cb = (CheckBox) convertView.findViewById(R.id.listview_select_cb);
            convertView.setTag(holder);
        } else {

        }
        final ItemBean bean = list.get(position);

                }
                // 回调方法，将Item加入已选
                onShowItemClickListener.onShowItemClick(bean);
            }
        });
        // 必须放在监听后面
        holder.cb.setChecked(bean.isChecked());
        return convertView;
    }

    static class ViewHolder {
