errors while adding ScrollView

I have multiple components in an activity and I want to add scroll bar to vertically scroll components from this android:id="@+id/regName_id" component to this android:id="@+id/regButton_id" component, but I am getting layout errors (errors in xml file). Please tell how can I do this?

XML Code of whole activity:

These elements are not siblings because they are not in the same layout: (Just remove these properties)

EditText at line 72:

 android:layout_below="@+id/loginPassword_id"

Button from line 235:

android:layout_alignLeft="@+id/appLogoImage_id"  
android:layout_alignStart="@+id/appLogoImage_id" 
android:layout_alignRight="@+id/appLogoImage_id"
android:layout_alignEnd="@+id/appLogoImage_id"

To create a scrollview between to layout element look at this example I hope it will help:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#ff003b"
    android:focusableInTouchMode="true"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin">

    <TextView
        android:id="@+id/textView"
        android:layout_width="match_parent"
        android:layout_height="20dp"
        android:text="TOP ELEMENT" />

    <!--Just a random height-->
    <ScrollView
        android:id="@+id/scrollView"
        android:layout_width="match_parent"
        android:layout_height="200dp"
        android:layout_below="@+id/textView">

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

            <TextView
                android:layout_width="match_parent"
                android:layout_height="20dp"
                android:layout_alignBottom="@+id/scrollView"
                android:text="SCROLLED ELEMENT" />
        </LinearLayout>

    </ScrollView>

    <TextView
        android:id="@+id/textView2"
        android:layout_width="match_parent"
        android:layout_height="20dp"
        android:layout_alignBottom="@+id/scrollView"
        android:text="BOTTOM ELEMENT" />

</RelativeLayout>
