Ich kann die Daten von der zweiten Anfrage-URL nicht anzeigen, um die erste Anfrage URL in Volley

Question

anzuhängen. Ich benutze Recycler View, um den Artikel anzuzeigen, aber ich habe zwei Anfrage-URL, um die Daten über Volley zu holen. Ich versuchte, aber nicht gut funktioniert, kann nicht erhalten zweite Daten von JSON URL via Volley abrufen.

Modell:

public class CartItemoriginal {

    this.productname = productname; 
    this.aliasname = aliasname; 
    this.qty = qty; 
    this.price = price; 
    this.delivery = delivery; 
    this.shippincharge = shippincharge; 
    this.sellername = sellername; 
    this.productid = productid; 
} 

public CartItemoriginal(String productimg, String productname, String aliasname, int qty, String price, String productid) { 
    this.productimg = productimg;

    this.qty = qty; 
    this.price = price; 
    this.productid = productid; 

} 
public CartItemoriginal(String delivery, String shippincharge, String sellername) { 
    this.delivery = delivery; 
    this.shippincharge = shippincharge; 
    this.sellername = sellername; 
} 


public int increaseQuantity(int quantity) { 
    if (quantity < 1) 
     quantity = 1; 
    else 
     quantity++; 

    Quantity = quantity; 
    return Quantity; 
} 

public String getProductimg() { 
    return productimg; 
} 

public void setProductimg(String productimg) { 
    this.productimg = productimg; 
} 

public String getProductname() { 
    return productname; 
} 

public void setProductname(String productname) { 
    this.productname = productname; 
}

}

    this.price = price; 
} 

public String getDelivery() { 
    return delivery; 
} 

public void setDelivery(String delivery) { 
    this.delivery = delivery; 
}

    return shippincharge; 
}

kann ich erster urloutput nicht zweite bekommen zu bekommen.

So lösen Sie diesen Fehler, Vielen Dank im Voraus.

Answer 1

Versuchen Sie, diese hinzuzufügen, nachdem zweiten Dienst nicht nach dem ersten Aufruf Aufruf

   recyleitems = (RecyclerView) findViewById(R.id.mycartitem); 
      llm = new LinearLayoutManager(CartItems.this); 
      llm.setOrientation(LinearLayoutManager.VERTICAL); 
      recyleitems.setLayoutManager(llm); 
      recyleitems.setHasFixedSize(true); 
      cartadapter = new CartlistAdapter(cart, CartItems.this); 
      Log.i(String.valueOf(cartadapter), "cartadapter"); 
      recyleitems.setAdapter(cartadapter); 
      cartadapter.notifyDataSetChanged(); 

und besserem Weg ist Ihre Ansicht nach in Ihrem onCreate erklären und nach dem Aufruf des Dienst nur Daten hinzufügen in benutzerdefinierten ArrayList und nach dem erfolgreichen Daten hinzugefügt in Ihrem List rufen Sie einfach youradapter.notifyDataSetChanged();
