Checkbox在listview android中取消选中？

Question

我知道有很多解决方案可以解决这个问题，但我不是一个正确的解决方案，当选中一个复选框时，我正在为它分配一个ID，并将其添加到一个数组中，但是当向下滚动时，取消选中该复选框，但ID存储在数组中，如果选中该复选框，我希望保持复选框。

我的适配器类是。

public class sendivitesadapter extends ArrayAdapter<Item> implements Filterable,SectionIndexer{
    private Context context;
    private ArrayList<Item> items;
    private qrusers qrusers;
    private LayoutInflater vi;
    private String[] udis;
    private final boolean[] mCheckedState;
    qrusers qrus;

    private ItemsFilter mFilter;

    public sendivitesadapter(Context context,ArrayList<Item> items,String[]udis) {
        super(context, 0,items);

        this.context = context;
        mCheckedState = new boolean[items.size()];
        this.qrusers =(qrusers) context;
        this.items = items;
        this.udis=uid;
        vi = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    }

    @Override
    public int getCount() {
        return items.size();
    }

    @Override
    public Item getItem(int position) {
        return super.getItem(position);
    }

    @Override
    public View getView(final int position, View convertView, ViewGroup parent) {

        View v = convertView;

        final Item i = items.get(position);

        if (i != null) {
            if(i.isSection()){
                SectionItem si = (SectionItem)i;
                v = vi.inflate(R.layout.checkboxlist, null);

                v.setOnClickListener(null);
                v.setOnLongClickListener(null);
                v.setLongClickable(false);

                final TextView sectionView = (TextView) v.findViewById(R.id.list_item_section_text);
                sectionView.setText(si.getTitle());

            }else{

Answer 1

如果要存储复选框的状态，则必须在内部ListView或您正在使用的任何结构以及扩展适配器中似乎称为items的结构中更新它，并且之后忘记打电话给notifyDataSetChanged()。

Answer 2

这个问题有你的答案。您必须维护一个单独的结构来检查/取消选中复选框。
