ScrollView doesn't show the upper part of XML

My XML was working perfectly, it has a listview, set of textviews, imageviews and buttons. Then I added a scroll view to the entire layout. Listview stopped functioning and then I added a custom class in order t o make it work. Now everything is working as intended, but the issue is that the top part of the layout is not visible when the xml loads, I have to scroll up to see the top part of it. My issue is same as this but still the provided solutions don't work: ScrollView doesn't show top part This is the XML file:

</ScrollView>

This is the class that was written to make both scroll view and the list view function at the same time:

public class Utility {

    public static void setListViewHeightBasedOnChildren(ListView listView) {
        ListAdapter listAdapter = listView.getAdapter(); 
        if (listAdapter == null) {
            // pre-condition
            return;
        }

        int totalHeight = 0;
        for (int i = 0; i < listAdapter.getCount(); i++) {
            View listItem = listAdapter.getView(i, null, listView);
            listItem.measure(0, 0);
            totalHeight += listItem.getMeasuredHeight();
        }

        ViewGroup.LayoutParams params = listView.getLayoutParams();
        params.height = totalHeight + (listView.getDividerHeight() * (listAdapter.getCount() - 1));
        listView.setLayoutParams(params);
    }

}

Put this in the OnCreate() method:

final ScrollView scrollview = ((ScrollView) findViewById(R.id.scrollview)); scrollview.post(new Runnable() {
  @Override public void run() {
    scrollview.fullScroll(ScrollView.FOCUS_UP);
  }
});

The code above provides you with a way to force the scroll of the ScrollView at the upper position. This behavior can be caused even by a weight attribute in a some layouts etc. The "debugging" of this will take more time that to apply the solution above and there isn't a guarantee that you can know each time which disturbs your initial scroll position.
