Listview inside a scrollview in xamarin

Question

I am a windows developer. I don't have much knowledge in android. So my scenario is like this: I have a scrollview which has its child as a linearlayout. The Linear layout has 3 listviews. I want to show all the items in all of the 3 listviews. The scrolling will be handled by the top level scrollview.

Will this work ?

<ScrollView
    android:scrollbars="vertical"
    android:scrollbarStyle="insideOverlay"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:id="@+id/scrollView1"
    android:fadeScrollbars="true">
    <LinearLayout
        android:orientation="vertical"
        android:minWidth="25px"
        android:minHeight="25px"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:id="@+id/linearLayout2">
        <RelativeLayout xmlns:tools="http://schemas.android.com/tools"

            android:layout_height="match_parent">

            <LinearLayout

I got to know that there is no direct way to achieve this, I followed the following method.

public static void SetListViewHeightBasedOnChildren(ListView listView) {
        IListAdapter listAdapter = listView.Adapter;
        if (listAdapter == null) {
            return;
        }

        int totalHeight = listView.PaddingTop + listView.PaddingBottom;
        for (int i = 0; i < listAdapter.Count; i++) {
            View listItem = listAdapter.GetView(i, null, listView);
            if (listItem is ViewGroup) {
                listItem.LayoutParameters = new global::Android.Views.ViewGroup.LayoutParams (global::Android.Views.ViewGroup.LayoutParams.WrapContent, global::Android.Views.ViewGroup.LayoutParams.WrapContent);
            }
            listItem.Measure(0, 0);
            totalHeight += listItem.MeasuredHeight;
        }

        global::Android.Views.ViewGroup.LayoutParams parameters = listView.LayoutParameters;
        parameters.Height = totalHeight + (listView.DividerHeight * (listAdapter.Count - 1));
        listView.LayoutParameters = parameters;
    }
