Textview wird nicht aktualisiert, basierend auf Position innerhalb pageradapter

Hallo ich habe ein Problem mit Pager-Adapter habe, wo ich nicht Textview aktualisieren, wenn die Schaltfläche Position Code basierend auf geklickt wird unterTextview wird nicht aktualisiert, basierend auf Position innerhalb pageradapter

Dies sind die beiden Tasten in meiner Einzelansicht von pageradapter Klasse.

<LinearLayout 
          android:layout_width="match_parent" 
          android:layout_height="match_parent" 
          android:layout_weight="1" 
          android:id="@+id/plusminuslayout" 
          android:orientation="horizontal"> 

          <Button 
           android:id="@+id/decrease" 
           android:layout_width="0dp" 
           android:layout_weight="0.3" 
           android:background="#e2364e" 
           android:layout_gravity="center" 
           android:layout_height="25dp" 
           android:textColor="#ffffff" 
           android:text="-" /> 

          <TextView 
           android:id="@+id/integer_number" 
           android:layout_width="0dp" 
           android:layout_weight="0.4" 
           android:gravity="center" 
           android:layout_gravity="center" 
           android:layout_height="wrap_content" 
           android:text="1" 
           android:textStyle="bold" 
           android:textSize="20sp" /> 

          <Button 
           android:id="@+id/increase" 
           android:layout_width="0dp" 
           android:layout_weight="0.3" 
           android:background="#e2364e" 
           android:layout_gravity="center" 
           android:layout_height="25dp" 
           android:textColor="#ffffff" 
           android:text="+" /> 

          <TextView 
           android:layout_width="0dp" 
           android:layout_weight="0.2" 
           android:gravity="center" 
           android:layout_gravity="center" 
           android:layout_height="wrap_content" 
           android:textStyle="bold" 
           android:textSize="20sp" /> 
         </LinearLayout>

Dies ist der Code innerhalb Instatiateitem() -Methode Textview Wert

holder.increase = (Button) itemView.findViewById(R.id.increase); 
      holder.decrese = (Button) itemView.findViewById(R.id.decrease); 
      holder.integerval = (TextView) itemView.findViewById(R.id.integer_number); 


      holder.increase.setTag(position); 
      holder.decrese.setTag(position); 
      holder.integerval.setTag(position); 
      holder.decrese.setOnClickListener(new View.OnClickListener() { 
       @Override 
       public void onClick(View v) { 
        quantity = quantity -1; 
        updateView(holder,v,position,quantity); 

       } 
      }); 

      holder.increase.setOnClickListener(new View.OnClickListener() { 
       @Override 
       public void onClick(View v) { 
        quantity = quantity + 1; 
        updateView(holder,v,position,quantity); 

       } 
      });

und das ist mein updateview() -Methode

private void updateView(ViewHolder holder,View v, int position,int quantity) { 

     holder.integerval.setText("" + quantity); 
    }

Textview ist die Aktualisierung auf dem dritten Seite von pageradapter zu aktualisieren und zufällig erhöht sich dieses Problem für alle Seiten. Jede Hilfe konnte wirklich schätzen.

setzen Sie Ihre ** Instatiateitem() ** vollständige Code –

Bitte überprüfen Sie meine Frage aktualisiert @Rahul Sharma –

Set-Tag für Ihre Ansicht und bekommen es auf Schaltfläche anklickt – Piyush

Fügen Sie eine weitere Parameter in Ihrem Produkt Klasse

public int quantity;

und innen Instatiateitem() hinzufügen

holder.integerval.setText("" + product.quantity);

und inside click listener machen es so

int pos = Integer.parseInt(v.getTag().toString()); 
Product obj = products.get(pos); 
obj.quantity = obj.quantity + 1; //do -1 in second listener 
notifyDataSetChage();

Ändern Sie den Namen Ihrer Klassen entsprechend.

Ich tat das gleiche, aber jede Seite innerhalb pageradapter ist mit dem gleichen Textview Wert aktualisiert, nicht in Betracht der Position @ Rahul Sharma –

dann müssen Sie Ihre ** Menge ** Wert in ** Produkt ** speichern. –

Ich habe meine Antwort geändert, bitte gehen Sie dies durch. –

Zuerst müssen Sie Tag für Ihre aufgeblasene Ansicht einstellen

itemView.setTag(position);

nun auf Click-Ereignis von Button-Tag bekommen Sie müssen mit mit findViewWithTag

View view = pager.findViewWithTag(position); 
if (view == null) { 
    return; 
}

Jetzt können Sie Ihre UI ids hier von

TextView price = (TextView) view.findViewById(R.id.price);

Jetzt aktualisieren Sie Ihre Benutzeroberfläche danach. Vergessen Sie auch nicht Adapter zu aktualisieren, nachdem das
