By the way, you will eventually need to write a C++ version of the currency
string formatter and use it here and elsewhere:

https://cs.chromium.org/chromium/src/chrome/android/java/src/org/chromium/chr...

https://cs.chromium.org/chromium/src/chrome/android/javatests/src/org/chromiu...

https://cs.chromium.org/chromium/src/chrome/android/junit/src/org/chromium/ch...

Then I can make CurrencyStringFormatter.java call into your
currency_string_formatter.h for code simplicity.

Makes sense, will do.

 
   return payments::CreatePaymentView(
-      l10n_util::GetStringUTF16(IDS_PAYMENT_REQUEST_ORDER_SUMMARY_TITLE),
+      CreateSheetHeaderView(
+          true,
+          l10n_util::GetStringUTF16(IDS_PAYMENT_REQUEST_ORDER_SUMMARY_TITLE),
+          this),
       std::move(content_view));
 }
 
 void OrderSummaryViewController::ButtonPressed(
     views::Button* sender, const ui::Event& event) {
-  DCHECK_EQ(kBackButtonTag, sender->tag());
-
-  dialog()->GoBack();
+  if (sender->tag() == CLOSE_BUTTON_TAG) {

no {}.
optional: use a switch statement.

[anthonyvd, 2017/01/04 19:08:55]

Done.

+    dialog()->CloseDialog();
+  } else if (sender->tag() == BACK_BUTTON_TAG) {
+    dialog()->GoBack();
+  }
 }
