Extra space When adding Grid View to ScrollView

I am using a GridView that is inside a scrollview (I know bad practice, but the requirements are just for this). The problem is that this is unwanted extra vertical space at the end of the GridView. I am also setting the height of the GridView dynamically using this code.

 public static void setHeightDynamically(GridView listView) {
        ListAdapter listAdapter = listView.getAdapter();
        if (listAdapter == null)
            return;

        int desiredWidth = View.MeasureSpec.makeMeasureSpec(listView.getWidth(), View.MeasureSpec.UNSPECIFIED);
        int totalHeight = 0;
        View view = null;
        for (int i = 0; i < listAdapter.getCount(); i++) {
            view = listAdapter.getView(i, view, listView);
            view.measure(desiredWidth, View.MeasureSpec.UNSPECIFIED);
            totalHeight += view.getMeasuredHeight();
        }
        ViewGroup.LayoutParams params = listView.getLayoutParams();
        params.height = totalHeight;
        listView.setLayoutParams(params);
        listView.requestLayout();
    }

      

        
        
        
      

    

My xml is like this

<RelativeLayout
    android:id="@+id/container"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <include
        android:id="@+id/header_section"
        layout="@layout/header_screen" />


    <ScrollView
        android:id="@+id/parent_scroll"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@android:color/white"
        android:layout_alignWithParentIfMissing="false"

        android:layout_below="@+id/header_section">

        <LinearLayout

                <FrameLayout
