</ScrollView>

Answer 1

   <?xml version="1.0" encoding="utf-8"?>
    <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical" >

        <ScrollView
            android:id="@+id/scrollView1"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_alignParentLeft="true"
            android:layout_alignParentTop="true" >

            <LinearLayout
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:orientation="vertical" >

<!--put here your button and all other-->
            </LinearLayout>
        </ScrollView>

    </RelativeLayout>

Answer 2

实际上它因为这个而无效

android:layout_alignParentBottom="true"

所以最后一个组件放在相对布局的底部而不是伸展到任何地方

如果要拉伸相对布局，请尝试使用

相互垂直添加组件堆栈

  android:layout_below="@+id/yourComponentBefore"

我举个例子

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

<RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="#b8fce8"
    android:gravity="bottom" >

    <TextView
        android:id="@+id/ComponentOne"
        android:layout_width="match_parent"
        android:layout_height="450dp"
        android:background="#CFCFCF" />

    <TextView
        android:id="@+id/ComponentTwo"
        android:layout_width="match_parent"
        android:layout_height="450dp"
        android:layout_below="@+id/ComponentOne"
        android:background="#FFFFFF" />

    <TextView
        android:id="@+id/ComponentThree"
        android:layout_width="match_parent"
        android:layout_height="450dp"
        android:layout_below="@+id/ComponentTwo"
        android:background="#000000" />
</RelativeLayout>

即使放入ScrollView，RelativeLayout也不会变得可滚动
