Answer 1

This is not correct design for starters but if you want to stick with the design one quick fix that will make your code work is to put both of your listViews inside one more list view and put that under scroll view. that should solve your problem of scrolling.

Answer 2

When placing ListView inside ScrollView I use the following method to set listView height and the scrolling works properly. Use this after you've added all views to your listview.

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

            int totalHeight = listView.getPaddingTop() + listView.getPaddingBottom();
            for (int i = 0; i < listAdapter.getCount(); i++) {
                 View listItem = listAdapter.getView(i, null, listView);
                 if (listItem instanceof ViewGroup) {
                    listItem.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
                 }
                 listItem.measure(0, 0);
                 totalHeight += listItem.getMeasuredHeight();
            }

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