Странная проблема с ListView, android. Повторный выход?

Question

Я создал собственный адаптер списка, который выводит список имен. Я передаю список только ONCE в пользовательский адаптер массива, который выводит имена на экране только в порядке. Но если я посмотрю на Logcat, я вижу, что он повторяется снова и снова примерно в 4 раза, даже если запрос, который поставляет данные, возвращает только 3 строки !!

Это может быть вызвано из-за класса GetterSetter (ImageItems), который я часто повторно использую в других настраиваемых ArrayAdapters ??

Я был бы очень рад, если бы кто-то помог мне понять это! :)

главный класс:

... 

public void getTastemakers() { 

     List<ImageItem> values = datasource.getTopTastemakers(); 
     for (int i = 0; i < values.size(); i++) { 


      TasteMakers ii = new TasteMakers(); 
      ii.setUser(values.get(i).getUser()); 
      ii.setUserId(values.get(i).getUserId()); 
      ii.setPostCount(values.get(i).getPostCount()); 


      tasteMakersList.add(ii); 
      if(tasteMakersList.size() == values.size()){ 
      addToRecomendedList(); 
     } 

     } 
    } 

    private void addToRecomendedList() { 
     // Find the ListView resource. 
     ArrayAdapter<TasteMakers> adapt = new RecomendedListAdapter(
       getActivity(), tasteMakersList); 
     TasteMakersListView.setAdapter(adapt); 
     TasteMakersListView.setOnItemClickListener(this); 

    } 

... 

пользовательские ArrayAdapter.class:

public class RecomendedListAdapter extends ArrayAdapter<TasteMakers> { 
    Context context; 
    List<TasteMakers> info; 
    private String LOGTAG; 
    private SendNotification sender; 

    public RecomendedListAdapter(Context context, List<TasteMakers> info) { 
     super(context, android.R.id.content, info); 
     this.context = context; 
     this.info = info; 
    } 

    @SuppressLint({ "DefaultLocale", "SimpleDateFormat" }) 
    @Override 
    public View getView(final int position, View convertView, ViewGroup parent) { 
     LayoutInflater vi = (LayoutInflater) context 
       .getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
     View view = vi.inflate(R.layout.recomended_users_rowlayout, null); 

     TasteMakers member = info.get(position); 
     System.out.println("position: " + position + "," + " Member name: " + member.getUser()); 

     Button followUserShort = (Button) view 
       .findViewById(R.id.followUserQuick); 
     followUserShort.setTag(position); 

     ImageView userImg = (ImageView) view.findViewById(R.id.userImg); 
     TextView name = (TextView) view.findViewById(R.id.userName); 
     name.setText(member.getUser()); 
     TextView postCount = (TextView) view.findViewById(R.id.postCount); 
     postCount.setText(member.getPostCount() + " postari"); 


     return view; 
    }

Answer 1

Используйте ViewHolder шаблон проектирования и BaseAdapter для пользовательского адаптера:

public class RecomendedListAdapter extends BaseAdapter { 

    Context context; 
    List<TasteMakers> info; 
    private String LOGTAG; 
    private SendNotification sender; 

    public RecomendedListAdapter(Context context, List<TasteMakers> info) { 
     this.context = context; 
     this.info = info; 
    } 

    @Override 
    public int getCount() { 
     return info.size(); 
    } 

    @Override 
    public long getItemId(int position) { 
     return position; 
    } 

    @Override 
    public Object getItem(int position) { 
     return info.get(position); 
    } 

    @Override 
    public View getView(final int position, View convertView, ViewGroup parent) { 
     ViewHolder holder; 
     if(convertView==null){ 
      holder = new ViewHolder(); 
      convertView = LayoutInflater.from(context).inflate(R.layout.recomended_users_rowlayout, null); 
      holder.followUserShort = (Button) view.findViewById(R.id.followUserQuick); 
      holder.userImg = (ImageView) view.findViewById(R.id.userImg); 
      holder.name = (TextView) view.findViewById(R.id.userName); 
      holder.postCount = (TextView) view.findViewById(R.id.postCount); 

      convertView.setTag(holder); 
     }else{ 
      holder = (ViewHolder) convertView.getTag(); 
     } 

     TasteMakers member = info.get(position); 
     System.out.println("position: " + position + "," + " Member name: " + member.getUser()); 

     holder.followUserShort.setTag(position); 
     holder.name.setText(member.getUser()); 
     holder.postCount.setText(member.getPostCount() + " postari"); 


     return convertView; 
    } 

    class ViewHolder { 
     Button followUserShort; 
     ImageView userImg; 
     TextView name; 
     TextView postCount; 
    } 
} 

Answer 2

не проблема. Попробуйте повторно просмотреть представления.

Try, чтобы увидеть

custom listview adapter getView method being called multiple times, and in no coherent order

ListView - getView is called too much times

Getview Called multiple times in android

Yet another getView called multiple times
