    if u want to display the price before just put txtTotalAmount.setText("Total Price = $ " + String.valueOf(overTotalPrice)); inside onBindViewHolder under

    int oneTypeProductTPrice = ((Integer.valueOf(model.getPrice()))) * Integer.valueOf(model.getQuantity());

    overTotalPrice = overTotalPrice + oneTypeProductTPrice;

    like this:

    int oneTypeProductTPrice = ((Integer.valueOf(model.getPrice()))) * Integer.valueOf(model.getQuantity());

    overTotalPrice = overTotalPrice + oneTypeProductTPrice;

    txtTotalAmount.setText("Total Price = SAR " + String.valueOf(overTotalPrice));

  7. thanku verry much for such a brilliant tutorial…but plz upload the source code after 19 tutorials .thanks

  8. do u have a video to make add to cart with displays the total purchase before to make calculate total price??

  9. Hi, could you add a thousand separator when displaying price, i mean how to add it ?

  10. 12:09 int eachProductTotalPrice = ((Integer.valueOf(model.getPrice()))) * Integer.valueOf(model.getQuantity()); why my app crash for this line of code??? Can anyone explain

  11. if you want to show price before write price code outside nextButtonClickLisner and also include
    protected void onStop() {
    overAllPriceOfProducts = 0;

    Without this code. When you minimize the program and open again the price will become double.

  12. if the app crash when you tap on the cart button in the CartActivity make sure the NextProcessBtn variable has the correct id, that is NextProcessBtn = (Button) findViewById(;

    The only issue to me in the fact that you need to click on the "Next" Button to have the overall price displayed.
    The overall price should be displayed automatically when the cart is displayed.
