You need to set a container layout which will be the father of all your linear layouts.

It looks something like this (The container can be Relative or Linear):

<ScrollView
    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:fillViewport="true">


    <RelativeLayout
        android:id="@+id/container"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:orientation="vertical">

    (all your view elements)

    </RelativeLayout>
</ScrollView>

The reason this is happening is because Scroll View needs to have a single child, try this (also works with a vertical linear layout):

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:background="@color/grey"
        >

    <RelativeLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            >
<!-- put the other stuff in here -->

    </RelativeLayout>
</ScrollView>

I suggest also toread about it a little bit, you might find some more usefull info.

Thats because you have a lot of LinearLayouts inside of your scrollView; You can have only one child (This child can have a lot of Childs of his own).
Try adding one LineartLayout with vertical orientation under the scrollView that will wrap all of the Childs. 

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@color/grey">

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

        <!-- put all of the other layouts here -->

</LinearLayout>
</ScrollView>
