Редактировать текст в списке дублированных данных при прокрутке

Question

У меня возникла эта проблема: в то время как представление списка повторяет представления, оно дублирует данные, вставленные в текст редактирования, и мне нужно только, чтобы тексты редактирования не дублировались, так что я получу правильное количество. Я пытался не перерабатывать представления, но при удалении прокручивал значения.

public class ArticleAdapter extends ArrayAdapter<Article>
{


    public  static List<Livraison_detail> MAJdb=new ArrayList<Livraison_detail>();;
    ViewHolder viewHolder;
    List<Article> articles=null;
    String []qtes;

    public ArticleAdapter(Context context, int resource, List<Article> objects)
    {
        super(context, resource, objects);
        articles=new ArrayList<>(objects);
        qtes=new String[articles.size()];
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent)
    {
        viewHolder= new ViewHolder();

        if(convertView==null){
            LayoutInflater infalter=LayoutInflater.from(getContext());
            convertView=infalter.inflate(R.layout.list_view_article,parent,false);


            viewHolder.designation = (TextView) convertView.findViewById(R.id.desi);
            viewHolder.quantité = (TextView) convertView.findViewById(R.id.qte_disp_2);
            viewHolder.prix = (TextView) convertView.findViewById(R.id.prix);
            viewHolder.qte=(EditText) convertView.findViewById(R.id.qte);

Answer 1

попробуйте это ... я изменил ваш метод getView () надеюсь, это поможет вам

@Override
public View getView(int position, View convertView, ViewGroup parent)
{
    viewHolder= new ViewHolder();

    if(convertView==null){
        LayoutInflater infalter=LayoutInflater.from(getContext());
        convertView=infalter.inflate(R.layout.list_view_article,parent,false);


        viewHolder.designation = (TextView) convertView.findViewById(R.id.desi);
        viewHolder.quantité = (TextView) convertView.findViewById(R.id.qte_disp_2);
        viewHolder.prix = (TextView) convertView.findViewById(R.id.prix);
        viewHolder.qte=(EditText) convertView.findViewById(R.id.qte);
        viewHolder.cb=(CheckBox)convertView.findViewById(R.id.cbarticle);





        convertView.setTag(viewHolder);

    }
    else {
        viewHolder =(ViewHolder)convertView.getTag();
    }
    viewHolder.cb.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                CheckBox check=(CheckBox)view;
                check.requestFocus();
                if (check.isChecked())

                            else{
                                l.QTE_LIVRE=Double.parseDouble(qtes[(int)check.getTag()]);
                                MAJdb.add(l);

private class ViewHolder

Answer 2

Трудно скомпилировать ваш код, чтобы проверить ошибку. Но, глядя на это, я могу сделать два предположения:

1. Хранение отдельных ViewHolder для каждой позиции ;

2. Не используйте View.setTag() метод для хранения значения position ;

   public static List<Livraison_detail> MAJdb = new ArrayList<Livraison_detail>();
   
   private SparseArray<ViewHolder> map = new SparseArray<>();
   List<Article> articles = null;
   String[] qtes;
   
   public ArticleAdapter(Context context, int resource, List<Article> objects) {
       super(context, resource, objects);
       articles = new ArrayList<>(objects);
       qtes = new String[articles.size()];
   }
   
   @Override
   public View getView(final int position, View convertView, ViewGroup parent) {
       ViewHolder viewHolder;
   
       if (convertView == null) {
           viewHolder = new ViewHolder();
           LayoutInflater infalter = LayoutInflater.from(getContext());
           convertView = infalter.inflate(R.layout.list_view_article, parent, false);
   
   
           viewHolder.designation = (TextView) convertView.findViewById(R.id.desi);
           viewHolder.quantité = (TextView) convertView.findViewById(R.id.qte_disp_2);
           viewHolder.prix = (TextView) convertView.findViewById(R.id.prix);
           viewHolder.qte = (EditText) convertView.findViewById(R.id.qte);
           viewHolder.cb = (CheckBox) convertView.findViewById(R.id.cbarticle);
   
   
           viewHolder.cb.setOnClickListener(
                   new View.OnClickListener() {
                       @Override
                       public void onClick(View view) {
                           CheckBox check = (CheckBox) view;
                           check.requestFocus();
                           if (check.isChecked()) {
                               Article a = articles.get(position);

                               try {
                                   if (qtes[position].equals("")) {
                                       throw new Exception();
                                   } else {
                                       if (Double.parseDouble(qtes[position]) > a.QTE_CHARGE) {
