AutocompleteTextView在android中没有正常工作listview

Question

我正在开发一个应用程序，其中我有一个listview。在每行中有一个textview和一个AutoCompleteTextview。现在我想要的是使autocompletetextview可编辑，即当我的列表中填充了一些数据时，我想编辑一些autocompletetexviews然后将更新的数据发送到服务器。有什么解决方案吗？我浪费了我2天的时间，我迫切需要这个。

这是我的customAdapter's getview()方法。我可以在listview中成功填充数据，并添加了＆＃34; addOnTextChangedListener＆＃34;到autocomletetextview。但是，当我过滤数据时，它无法设置为auotocompletetext，即autocomtextview.settext(filtereddata)没有执行。我在onTextChanged()中获取过滤文本在我的代码中我写了这个，但我不知道实际放在哪里。

public View getView(final int position, View convertView, ViewGroup parent)
{
   LayoutInflater inflater= (LayoutInflater)activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

if(convertView==null)
{
    convertView=inflater.inflate(R.layout.new_applwizard_extuser_listrow,null);


TextView appl_Name=(TextView)convertView.findViewById(R.id.ext_app_name);

auto_brand_Name=(AutoCompleteTextView)convertView.findViewById(R.id.ext_auto_brand_txt);
auto_brand_Name.setFocusable(true);
auto_brand_Name.setFocusableInTouchMode(true);

ToggleButton toggle_status=(ToggleButton)convertView.findViewById(R.id.ext_toggle_cover);
LinearLayout ll_save_btn=(LinearLayout)convertView.findViewById(R.id.ll_ext_btn_appsubmit);

try
{

    appl_Name.setText(alApplianceDetails.get(position).getAppliance_Name().toString());

    if(alApplianceDetails.get(position).getStatus()==true)
    {
        toggle_status.setChecked(true);
    }
    else
    {
        toggle_status.setChecked(false);
    }


    if(alApplianceDetails.get(position).getBrand_Id()!=0)
    {
        String brand_name=null;
        brand_name=dbHandler.getBrand_id(String.valueOf(alApplianceDetails.get(position).getBrand_Id()));
        Log.d("brand name", brand_name);

        auto_brand_Name.setText(brand_name);
    }
    else
    {
        Log.d("brand name", "no brand");

    }


    try

    auto_brand_Name.setOnItemClickListener(new OnItemClickListener()

             String selection = parent.getItemAtPosition(position).toString();
             //auto_brand_Name.setText(selection);

             Log.d("adpter value..",""+parent.getAdapter().getItem(position).toString());
