java.lang.IllegalStateException: ScrollView can host only one direct child [duplicate]

Question

I'm simply trying to add the ability to scroll through this layout by adding a scrollview however every time I attempt to load the layout I'm getting an error stating "java.lang.IllegalStateException: ScrollView can host only one direct child" and I'm unsure why.

Any suggestions are much appreciated.

Just as the error says

ScrollView can host only one direct child

Wrap the Views inside of a LinearLayout so the ScrollView has only the LinearLayout as a direct child.

From the Docs

A ScrollView is a FrameLayout, meaning you should place one child in it containing the entire contents to scroll; this child may itself be a layout manager with a complex hierarchy of objects. A child that is often used is a LinearLayout in a vertical orientation, presenting a vertical array of top-level items that the user can scroll through.

<ScrollView
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_weight="1" >
      <LinearLayout android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:orientation="vertical">
           // all the views currently in your ScrollView
     </LinearLayout>
</ScrollView>
