当按钮停留在底部时水平和垂直滚动

Question

我有一个 Android 应用程序，它有一个可以显示自定义数据的活动。

我需要水平和垂直，scrollbars以便在尺寸大于屏幕时可以看到数据。

所以我尝试添加一个HorizontalScrollView，它添加了水平滚动，但现在按钮不再粘在屏幕底部。我该怎么办？

<?xml version="1.0" encoding="utf-8"?>

<android.support.constraint.ConstraintLayout 

xmlns:android="http://schemas.android.com/apk/res/android"

xmlns:app="http://schemas.android.com/apk/res-auto"

xmlns:tools="http://schemas.android.com/tools"

android:layout_width="match_parent"

android:layout_height="match_parent"

app:layout_behavior="@string/appbar_scrolling_view_behavior"

tools:context=".activities.UserModeAdvancedActivity"

tools:showIn="@layout/activity_user_mode_advanced">

<ScrollView

    android:layout_width="match_parent"

    android:layout_height="match_parent"

    android:fillViewport="true">

    <HorizontalScrollView

        android:fillViewport="true"

        android:layout_width="match_parent"

        android:layout_height="match_parent">

    <LinearLayout

        android:layout_width="match_parent"

        android:layout_height="wrap_content"

        android:orientation="vertical">

        <TableLayout

            android:id="@+id/tableLayout_user_mode_advanced"

            android:layout_width="match_parent"

            android:layout_height="0dp"

            android:layout_marginStart="24dp"

            android:layout_weight="1"

            android:padding="6dp"

            android:stretchColumns="*"

            app:layout_constraintStart_toStartOf="parent"

            tools:layout_editor_absoluteY="0dp">

        </TableLayout>

</android.support.constraint.ConstraintLayout>
