水平和垂直滚动,而按钮停留在底部



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以便如果尺寸大于屏幕,则可以看到数据。

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

android:layout_height="match_parent"

嘿,尝试以下代码:-

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:weightSum="10"
android:orientation="vertical">
<ScrollView
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="9"
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>
</LinearLayout>
</HorizontalScrollView>
</ScrollView>
<LinearLayout
android:layout_height="0dp"
android:layout_weight="1"
android:layout_width="match_parent"
android:gravity="center_horizontal">
<Button
android:id="@+id/buttonAlarmOverview"
android:layout_width="200dp"
android:layout_height="wrap_content"
android:background="@drawable/rounded_button"
android:onClick="onButtonClick"
android:text="@string/button_show_more" />
</LinearLayout>
