android - ScrollView 中的约束布局

我正在寻找构建一个 UI，我想在其中显示横向滚动并将按钮保持在屏幕的最底部并粘在页脚上，但在横向 View 期间滚动之间应该有公平的差距。

非常感谢任何帮助。

[ Also in portrait view there is a small padding around the button not sure why?[2]

我认为您应该像这样更改代码:

<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"

    app:layout_constraintTop_toTopOf="parent"
