Question

这是我的联系人选择列表活动，其中包含联系人列表。我想通过复选框选择多个联系人并将数据发送给他们。问题是：当我检查一个联系人并向下滚动列表视图时，我回来自动向上滚动选中的复选框

这是我的联系人选择器活动：

if (cb.isChecked()) {
                        Log.i("in if check box", receiver_id+"++++");

                        obj_Send_data = new send_data();
                        obj_Send_data.setReceiver_id(receiver_id);
                        obj_Send_data.setGcm_reg_id(gcm_reg_id);
                        id_arrArrayList.add(obj_Send_data);
                        Log.i("arraylist in if lisze", "++"+ id_arrArrayList.size());

                        Log.i("array list obj","++"+obj_Send_data);

                    } else if (!cb.isChecked()) {

                        id_arrArrayList.remove(obj_Send_data);
                        Log.i("arraylist in else lisze", "++"+ id_arrArrayList.size());

                    }

public class CustomListViewAdapter extends BaseAdapter {

    Context cm1;

    public int getCount() {
        return itemdetails.size();
    }

    public Object getItem(int arg0) {
        return itemdetails.get(arg0);
    }

    public long getItemId(int arg0) {
        return arg0;
    }

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

        final ViewHolder holder;
        View vi = convertView;

        if(vi==null)
            vi = l_inflater.inflate(R.layout.custcontactview, null);

            holder = new ViewHolder();

            holder.number = (TextView) vi.findViewById(R.id.txtContactNumber);

            holder.name.setText(itemdetails.get(position).getcontactName());
            holder.number.setText(itemdetails.get(position).getcontactNumber());

            if(!image1.get(position).equals("0")){

                holder.ch.setTag(vi.getTag());
                Log.i("tag", vi.getTag()+"==");
            }

        itemdetails.clear();
        if (charText.length() == 0) {
            itemdetails.addAll(arraylist);
        } else {
            for (int i=0;i<arraylist.size();i++ ) {
                if (arraylist.get(i).getcontactName().toLowerCase(Locale.getDefault())
                        .contains(charText)) {
                    Log.i("serch", arraylist.get(i).getcontactName());
                    itemdetails.addAll(arraylist);
                }
            }
        }
        notifyDataSetChanged();
    }
}

其getview()方法行为，每次用户滚动视图时都会创建新视图。在我的博客上查看我的帖子简单替换toggle button with checkbok并执行它。

Getview Method Wierd in Listview

Android：向下滚动到列表视图后自动取消选中复选框
