朋友们,

我正在使用以下代码来检查/取消选中ListvIEw中的复选框

public AdapterBank(Context context,List<Bank> List,ListVIEw lst) {     mInflater = LayoutInflater.from(context);      this.context = context;      ListvIEw = lst;      banks= List;    }     public VIEw getVIEw(final int position, VIEw convertVIEw, VIEwGroup parent) {          VIEwHolder holder;          if (convertVIEw == null) {            convertVIEw = mInflater.inflate(R.layout.List_banks, null);            holder = new VIEwHolder();            holder.bankname = (TextVIEw) convertVIEw.findVIEwByID(R.ID.bankname);            holder.bankIcon = (ImageVIEw) convertVIEw.findVIEwByID(R.ID.bankIcon);            holder.checkBox = (CheckBox) convertVIEw.findVIEwByID(R.ID.checkBox);            convertVIEw.setTag(holder);          } else {            holder = (VIEwHolder) convertVIEw.getTag();          }          Bank bank = getItem(position);          holder.checkBox.setonCheckedchangelistener(new OnCheckedchangelistener() {                @OverrIDe                public voID onCheckedChanged(Compoundbutton checkBoxVIEw, boolean isChecked) {                    banks.get(position).setSelected(isChecked);                    //Toast.makeText(context, "" + position, Toast.LENGTH_LONG).show();                }            });          if(bank.isSelected())            {                holder.checkBox.setChecked(true);            }else            {                holder.checkBox.setChecked(false);            }

当我选中任何复选框并滚动它.选中复选框不再检查.
任何人指导我在这做什么错？

解决方法:

您可以尝试使用静态侦听器(可能无法纠正您的错误,但肯定会降低您正在创建的“临时”对象的数量)：

public VIEw getVIEw(final int position, VIEw convertVIEw, VIEwGroup parent) {    VIEwHolder holder;    if (convertVIEw == null) {        convertVIEw = mInflater.inflate(R.layout.List_banks, null);        holder = new VIEwHolder();        holder.bankname = (TextVIEw) convertVIEw.findVIEwByID(R.ID.bankname);        holder.bankIcon = (ImageVIEw) convertVIEw.findVIEwByID(R.ID.bankIcon);        holder.checkBox = (CheckBox) convertVIEw.findVIEwByID(R.ID.checkBox);        holder.checkBox.setonCheckedchangelistener(checkListener);        convertVIEw.setTag(holder);    } else {        holder = (VIEwHolder) convertVIEw.getTag();    }    Bank bank = getItem(position);    holder.checkBox.setTag(bank);    holder.checkBox.setChecked(bank.isSelected());    return convertVIEw;}private OnCheckedchangelistener checkListener = new OnCheckedchangelistener() {   @OverrIDe   public voID onCheckedChanged(Compoundbutton checkBoxVIEw, boolean isChecked) {     Bank b = (Bank) checkBoxVIEw.getTag();     b.setSelected(isChecked);   }});
