Если у меня есть горизонтальное представление, созданное в xml.

Есть ли какой-нибудь способ создать горизонтальное прокручиваемое представление в этом представлении ?

Заранее спасибо.

Вы можете использовать HorizontalScrollView

Образец

MainActivity.java

        FrameLayout frameLayout = findViewById(R.id.container);
        if (frameLayout != null) {
            frameLayout.addView(horizontalScrollView);
        }
