重:每个ListItem是属于ListItem自己的,不能够放到ViewHolder中,而是数据源每项的.

@Override    public View getView(int position, View convertView, ViewGroup parent) {        ViewHolder holder;        if (convertView == null) {            convertView = LayoutInflater.from(parent.getContext()).inflate(R.layout.inbox_list_item, parent, false);            holder = new ViewHolder(convertView);        } else {            holder = (ViewHolder) convertView.getTag();        }        ReceiveBoxResponse.ListBean bean = list.get(position);        holder.from_username.setText(bean.getFrom_username());        holder.content.setText(bean.getTitle());        holder.time.setText(bean.getCreate_time());        //是否已读        Object  tag=holder.time.getTag();        if (tag == null) {            QBadgeView qBadgeView=new QBadgeView(parent.getContext());//            qBadgeView.bindTarget(holder.overlay_badge);            qBadgeView.setBadgeGravity(Gravity.START | Gravity.TOP);            if("0".equals(bean.getHas_read())) {                qBadgeView.setBadgeNumber(1);////1:已读,0:未读            }else {                qBadgeView.setBadgeNumber(0);            }            holder.time.setTag(qBadgeView);        }else{            QBadgeView qQBadgeView=(QBadgeView)tag;            if("0".equals(bean.getHas_read())) {                qQBadgeView.setBadgeNumber(1);////1:已读,0:未读            }else {                qQBadgeView.setBadgeNumber(0);            }        }        if(mStateIsEdit){            holder.check_box.setVisibility(View.VISIBLE);            if(bean.isState()){                holder.check_box.setChecked(true);            }else{                holder.check_box.setChecked(false);            }        }else{            holder.check_box.setVisibility(View.GONE);        }        return convertView;    }
