Android 视图，从底部开始元素在小屏幕上与 header 重叠

Question

我有一个示例视图，顶部是徽标 + header 分隔线 + 一些描述，从底部开始：按钮 + 一些复选框，请参见下图：

它在当前设备上看起来不错，但在旧手机上，当屏幕较小（例如 5 英寸）时 - 元素重叠：

视图如下所示：

<androidx.constraintlayout.widget.ConstraintLayout android:id="@+id/parent"
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">

<!-- TOP -->

  <ImageView
        android:id="@+id/logo"
        android:layout_width="0dp"
        android:layout_height="wrap_content"

    <ImageView

        android:layout_marginTop="25dp"
        app:layout_constraintWidth_percent="0.7" />

</androidx.constraintlayout.widget.ConstraintLayout>

我应该如何在视图的这两部分之间设置约束，使它们在小屏幕上不会重叠？在底部添加 marginTop?

我找到了答案，会在下面post，也许对以后的人有帮助：

我复制了 ScrollView 底部部分的所有元素：

  <ScrollView
        android:layout_width="match_parent"
        android:layout_height="0dp"
        app:layout_constraintTop_toBottomOf="@+id/header"
        app:layout_constraintBottom_toBottomOf="parent"
        android:fillViewport="true" >

        <androidx.constraintlayout.widget.ConstraintLayout
            android:layout_width="match_parent"
            android:layout_height="0dp" >

      <!-- all LinearLayout's from bottom section -->

      </androidx.constraintlayout.widget.ConstraintLayout>
    </ScrollView>
</androidx.constraintlayout.widget.ConstraintLayout>

Android 视图，从底部开始元素在小屏幕上与 header 重叠
