我正在使用NFC标签制作应用程序,我必须阻止NFC标签克隆.我已经看到许多其他NFC标签,当试图克隆时,会显示弹出消息"克隆受限制,标签由密钥保护",我希望我的NFC标签具有相同的安全性.

一切都工作正常,但现在我没有得到正在发生的事情,我有10项目在listView中显示,它的工作正常,直到第6项,然后再次从第一项重复？

    public class GroupDetailsAdapter extends BaseAdapter {
        List<GetSetGroupDetails> group_details = new ArrayList<GetSetGroupDetails>();
        Context context;
        Typeface face;

        public GroupDetailsAdapter(List<GetSetGroupDetails> group_details,

            super();
            this.group_details.clear();
            this.group_details = group_details;
            this.context = context;
            face = Typeface.createFromAsset(context.getAssets(),
                    "HelveticaNeueLTStd-Th.otf");
        }

        @Override
        public int getCount() {
            // TODO Auto-generated method stub
            int count = group_details.size();
            return count;
        }

        @Override
        public Object getItem(int arg0) {
            // TODO Auto-generated method stub
            return null;
        }

        @Override
        public long getItemId(int position) {
            // TODO Auto-generated method stub
            return position;
        } …
