ScrollBars in my ScrollView does not show unless I touch the ScrollView

Question

I have a layout that contains several items.

It contains a ScrollView.

Now, I want the ScrollBar to be always visible.

I have tried:

android:fadeScrollbars="false"

android:scrollbarAlwaysDrawVerticalTrack="true"

setVerticalScrollBarEnabled (false)

android:scrollbarFadeDuration="0"

But the ScrollBar does not show, unless I touch the ScrollView (in that case it shows and stays as expected).

Please I need the ScrollBar to be always visible (even if not touched),

so that the user knows that he can scroll that element.

Thanks!!

This is the relevant java snippet:

rLayout = (LinearLayout) findViewById(R.id.text);

    ScrollView sv=(ScrollView)findViewById(R.id.scroll);
    sv. setScrollbarFadingEnabled(false);
    sv.requestFocus();
        if (((LinearLayout) rLayout).getChildCount() > 0) {
                ((LinearLayout) rLayout).removeAllViews();
            }
            desc = new ArrayList<String>();
            date = new ArrayList<String>();
            ((CalendarAdapter) parent.getAdapter()).setSelected(v);
            selectedGridDate = CalendarAdapter.dayString.get(position);
            String[] separatedTime = selectedGridDate.split("-");
            String gridvalueString = separatedTime[2].replaceFirst("^0*",
                    "");// taking last part of date. ie; 2 from 2012-12-02.
            int gridvalue = Integer.parseInt(gridvalueString);
            // navigate to next or previous month on clicking offdays.
            if ((gridvalue > 10) && (position < 8)) {
                setPreviousMonth();
                refreshCalendar();
            } else if ((gridvalue < 7) && (position > 28)) {
                setNextMonth();
                refreshCalendar();
            }
            ((CalendarAdapter) parent.getAdapter()).setSelected(v);
            selectedevents.clear();
            for (int i = 0; i < Utility.startDates.size(); i++) {
                if (Utility.startDates.get(i).equals(selectedGridDate)) {
                    desc.add(Utility.nameOfEvent.get(i));
                }
                if (sdf.format(events.get(i).dtstart).equalsIgnoreCase(
                        selectedGridDate)) {
                    selectedevents.add(events.get(i));
                }
            }

            if (desc.size() > 0) {
                for (int i = 0; i < selectedevents.size(); i++) {
                    LayoutInflater li = LayoutInflater.from(CalendarView.this);

                    View row = li.inflate(R.layout.event_row, null);
                    TextView eventname=(TextView)row.findViewById(R.id.eventname);
                    TextView eventtype=(TextView)row.findViewById(R.id.eventtype);

                    eventname.setText(selectedevents.get(i).title);
                    rLayout.addView(row);
                           }
