Android 在Listview中，取消复选框的状态

当我滚动listview时，我选中的复选框会互换

我的适配器类：

public class AdapterInvitePartner extends ArrayAdapter<FindPartnerPojo> {
    private LayoutInflater inflater;
    private List<FindPartnerPojo> objectList;
    private List<String> checkboxCheckedList= new ArrayList<String>();
    int i = 0;

    public AdapterInvitePartner(Context context, int textViewResourceId,
            List<FindPartnerPojo> objects) {
        super(context, R.layout.items_find_partners, objects);
        this.objectList = objects;
        this.inflater = LayoutInflater.from(context);

    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        ViewHolder holder;
         FindPartnerPojo item = objectList.get(position);
         final String id=item.getUserid();
        if (convertView == null) {

            convertView = inflater.inflate(R.layout.items_find_partners, null);

            holder = new ViewHolder();

            holder.partner_email_addr_textview = (TextView) convertView
                    .findViewById(R.id.textView_partner_email_addr);
            holder.partner_phone_number_textview = (TextView) convertView
                    .findViewById(R.id.textView_partner_phone_number);
            holder.checkbox = (CheckBox) convertView
                    .findViewById(R.id.partner_checkBox);

            holder.checkbox
                    .setOnCheckedChangeListener(new OnCheckedChangeListener() {

                        public void onCheckedChanged(CompoundButton buttonView,
                                boolean isChecked) {
                            if (isChecked) {
                                checkboxCheckedList.add(id);
                            } else {
                                checkboxCheckedList.remove(id);
                            }

                        }

                    });

            convertView.setTag(holder);
            i++;
        }
        // if it's exist convertView then consume it
        else {
            holder = (ViewHolder) convertView.getTag();
        }
        holder.partner_email_addr_textview.setText(item.getEmail());
        holder.partner_phone_number_textview.setText(item.getPhone_number());

        return convertView;

    }

    static class ViewHolder {
        TextView partner_email_addr_textview, partner_phone_number_textview;
        CheckBox checkbox;
    }

    public List<String> getCheckBoxList() {
        return checkboxCheckedList;
    }

}

在回收convertView时，必须手动重置复选框的值

@Override
    public View getView(int position, View convertView, ViewGroup parent) {
        ViewHolder holder;
         FindPartnerPojo item = objectList.get(position);
         final String id=item.getUserid();
        if (convertView == null) {

        convertView = inflater.inflate(R.layout.items_find_partners, null);

        holder = new ViewHolder();

        holder.partner_email_addr_textview = (TextView) convertView
                .findViewById(R.id.textView_partner_email_addr);
        holder.partner_phone_number_textview = (TextView) convertView
                .findViewById(R.id.textView_partner_phone_number);
        holder.checkbox = (CheckBox) convertView
                .findViewById(R.id.partner_checkBox);
        convertView.setTag(holder);
        i++;
    }
    // if it's exist convertView then consume it
    else {
        holder = (ViewHolder) convertView.getTag();
    }
    holder.partner_email_addr_textview.setText(item.getEmail());
    holder.partner_phone_number_textview.setText(item.getPhone_number());
        **holder.checkbox
                .setOnCheckedChangeListener(null);
        holder.checkbox.setChecked(the_original_value);**
        holder.checkbox
                .setOnCheckedChangeListener(new OnCheckedChangeListener() {

                    public void onCheckedChanged(CompoundButton buttonView,
                            boolean isChecked) {
                        if (isChecked) {
                            checkboxCheckedList.add(id);
                        } else {
                            checkboxCheckedList.remove(id);
                        }

                    }

                });


    return convertView;

}

由于视图循环，您必须设置所有可以在getView中显式更改的属性。特别是，选中状态：

holder.checkbox.setChecked(checkboxCheckedList.contains(id));

如果之前已选中，则将选中该复选框

@Override

public int getViewTypeCount() {                 

    return getCount();
}

@Override
public int getItemViewType(int position) {

    return position;
}

将这两种方法添加到适配器中。从这里

看看这个链接：这太糟糕了。您基本上是告诉适配器不要回收任何视图，而是始终创建一个新视图！此外，它可能仍然会在同一索引中为视图回收视图，可能最终会有效地复制图像。我不明白的是，您链接到的问题包含一个有效且正确的答案，并且在您引用的答案之上被接受。

@Override

public int getViewTypeCount() {                 

    return getCount();
}

@Override
public int getItemViewType(int position) {

    return position;
}
