Unable to scroll Linear Layout with ScrollView

Question

I am new to Android. I am creating a form to add users. As the form fields are many, I need to scroll down. I read that the ScrollView takes only one child view. I have wrapped my view inside a Linear Layout which is the direct child of the ScrollView.

<ScrollView
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:background="@color/colorWhite"
                android:animateLayoutChanges="true"
                android:scrollbars="none">
        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:orientation="vertical">

                <EditText... />

                <EditText.../>

                <EditText... />

                <EditText.../>

                <LinearLayout... >

                <LinearLayout... >

                <LinearLayout... >

                <TextView... />
     </LinearLayout>
 <ScrollView/>

    android:layout_width="match_parent"  
    android:layout_height="wrap_content"  
    android:id="@+id/scrollView">  


    <LinearLayout
