Trouble scrolling 2 ScrollViews on a FrameLayout

I have a FrameLayout which has a ScrollView as the only child. During runtime I inflate a RelativeLayout which has a ScrollView within and add it to the FrameLayout开发者_如何学Go (This child view now overlaps the previous ScrollView). I have used a LockableScrollView as the first child of the FrameLayout so, I can disable it's scrolling by setting the scrollable property to false, the focusable and clickable properties are also set to false after the new child is added to the FrameLayout. But still I'm unable to scroll the new ScrollView. Any pointers?

The following is the Root layout.

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/frame"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">

    <RelativeLayout
        android:id="@+id/relative_layout"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:background="@drawable/questions_bg">

        <ImageView
            android:id="@+id/questions_header"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_alignParentTop="true"
            android:scaleType="fitXY"
            android:src="@drawable/header_bg" />

        <com.package.ui.LockableScrollView
            android:id="@+id/question_scrollview"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:layout_below="@id/questions_header"
            android:scrollbarAlwaysDrawVerticalTrack="true"
            android:scrollbarStyle="insideOverlay"
            android:scrollbarFadeDuration="0"
            android:fillViewport="true">

            <!-- Some more views -->

        </com.package.ui.LockableScrollView>    
    </RelativeLayout>
</FrameLayout>

The following is the child layout that is inflated during runtime and added to the FrameLayout.

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_gravity="bottom|center_horizontal"
    android:layout_marginBottom="20dp">

    <ImageView
        android:id="@+id/q_map_header"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:src="@drawable/en_question_map_header" />

    <ImageView
        android:id="@+id/q_map_bg"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:layout_below="@id/q_map_header"
        android:src="@drawable/question_map_content" />

    <ImageView
        android:id="@+id/q_map_footer"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:layout_below="@id/q_map_bg"
        android:paddingBottom="50dp"
        android:src="@drawable/en_question_map_footer" />

    <ScrollView
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_below="@id/q_map_header"
        android:layout_above="@id/q_map_footer"
        android:layout_marginLeft="28dp"
        android:layout_marginRight="30dp"
        android:layout_marginTop="14dp"
        android:layout_marginBottom="14dp"
        android:layout_alignLeft="@id/q_map_header"
        android:layout_alignRight="@id/q_map_header"
        android:fillViewport="true" >

        <GridView
            android:id="@+id/q_map_grid"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:numColumns="5"
            android:verticalSpacing="8dp"
            android:horizontalSpacing="8dp"
            android:stretchMode="columnWidth"
            android:gravity="center_horizontal" />
    </ScrollView>
</RelativeLayout>

You can't place a scrollable container (Here GridView) within another scrollable container (Here ScrollView).
