Android: Vertical Scrollbar

Question

enter image description here

I want to achieve this in list view and gridview. Please Guide me. On the long click of down arrow, i want to come to the end of the of the list.

Not necessary for list view or grid view only. Can be implemented on any layout. — sneaker_android, Nov 29 '12 at 06:49
What i just want is a customized vertical seek bar which drags my list view up and down, and two buttons one on each side that also drag my list view up n down accordingly. Thats it. Thank you. — sneaker_android, Nov 29 '12 at 07:15

You can use setSelection(index), the listview display will jump to the index you want

downButton.setOnLongClickListener(new OnLongClickListener() { 
        @Override
        public boolean onLongClick(View v) {

   listView.setSelection(LastPositionIndex);

            return true;
        }
    });

EDITED

See this link, not exactly what you want but similar, I think you will require custom listview for your purpose.

No Sorry. I want a simple implementation. Thats it. – sneaker_android Nov 29 '12 at 07:18
I am afraid there isn't any simpler implementation other than custom view – Androider Nov 29 '12 at 07:24
