//这是我的适配器。现在每个人都运行正常，但我想垂直制作这个封面流。在xml中没有设置方向的选项..我试过http://www.codeproject.com/Articles/146145/Android-3D-Carousel ..但我不想要这种类型的旋转木马布局我需要简单的垂直旋转木马布局。

Answer 1

现在您可以使用viewpager2实现此目的。我们可以指定方向，例如recyclerview'viewPager.orientation = ORIENTATION_VERTICAL'。

经历这个

Answer 2

有很多解决方法可以实现它。但是我更喜欢使用支持垂直方向的viewPager2。

或者您可以使用库来实现它，例如this library
