Wie u irgendwann die Position wiederholt wird sehen, obwohl ich Ex verschiebe nach unten: Position 4,12

ich kann nicht den Quellcode einfügen, weil sie vertraulich

Vielen Dank im Voraus

EDIT:

rv.addOnScrollListener(new EndlessRecyclerOnScrollListener(linearLayoutManager) { 
       @Override 
       public void onLoadMore(int current_page) { // when we have reached end of RecyclerView this event fired 
        if (canMakeRequest()) { 
         //load more data and notify adapter 
        } 
       } 
      }); 
      //load data and set adapter 

Answer 1

Überschreiben Sie getItemViewType und geben Sie die Position in Ihrem Recyclerview-Adapter zurück und alles wird gut.

@Override 
public int getItemViewType(int position) { 
    return position; 
} 

Answer 2

Meine Vermutung, für Annahme Sie eine Textview haben Liste der Namen in recyclerview Mittel aufzufüllen, in bindViewHolder() Funktion müssen Sie Textview jedes Mal aktualisieren.

Sie if() Zustand Angenommen haben Daten zu aktualisieren, dann sollte es sonst Zustand seine für alternativen Wert Textview sonst aktualisieren die vorherigen Daten zeigt nur.
