这是我想在 Android 活动中获得的内容:

目标:
我尝试了 ConstraintLayout 和 Linearlayout 的多种组合,但都没有成功:
这是一个不起作用的代码示例(简化):
<androidx.constraintlayout.widget.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout android:layout_width="match_parent"
android:layout_height="0dp"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintBottom_toTopOf="@id/B2"
android:orientation="vertical">
<ScrollView android:id="@+id/S1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:scrollbars="vertical"
android:layout_weight="0">
<TableLayout android:id="@+id/table"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<TableRow >...</TableRow>
<TableRow >...</TableRow>
<TableRow >...</TableRow>
</TableLayout>
</ScrollView>
<LinearLayout>.....</LinearLayout>
</LinearLayout>
<Button android:id="@+id/B2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="validate"
app:layout_constraintBottom_toBottomOf="parent" />
</androidx.constraintlayout.widget.ConstraintLayout>
我知道我可以通过使用 OnPreDrawListener 来实现这一点,但我更喜欢更静态的东西,只需使用 xml 中的布局。
我怎样才能实现这个目标?
这应该有效,至少在预览中是这样: 我希望我正确理解了您的要求。

LinearLayout 为蓝色,表格单元格为绿色和红色
