Listview错误第一个和最后一个项目

Question

我有ListView，我使用EditText和Button创建了一个布局，问题是当我在列表的第一项中写入时，自动列表的最后一项设置相同的信息。我在我的ViewHolder适配器中使用。

我的适配器示例：

public View getView(int position, View view, ViewGroup parent) { 
        final ViewHolder holder;

        if (view == null){
            LayoutInflater layoutInflater = LayoutInflater.from(context);
            view = layoutInflater.inflate(R.layout.lst_autocomplete, parent, false);
            holder = new ViewHolder();
            holder.direction = (AutoCompleteTextView) view.findViewById(R.id.autoComplete);
            holder.information= (TextView) view.findViewById(R.id.txtInformation);
            holder.tag = (EditText) view.findViewById(R.id.txtTag);
            holder.check= (CheckBox) view.findViewById(R.id.chkCheck);
            holder.product = (EditText) view.findViewById(R.id.txtProduct);
            view.setTag(holder);
        }else{
            holder = (ViewHolder) view.getTag();
        }

        CustomAdapter adapter  = new CustomAdapter(context, cutom_list.lst_product);

        holder.direction.setAdapter(adapter);
        holder.direction.setThreshold(1);

        holder.direction.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                Global list= (Global) parent.getItemAtPosition(position);
                holder.direction.setText(list.getDesc());
                holder.information.setText(list.getUbi());
            }
        });
