Programmatically scroll to a specific position in an Android ListView

Question

For a direct scroll:

getListView().setSelection(21);

For a smooth scroll:

getListView().smoothScrollToPosition(21);

For a SmoothScroll with Scroll duration:

getListView().smoothScrollToPositionFromTop(position,offset,duration);

Parameters
position -> Position to scroll to
offset ---->Desired distance in pixels of position from the top of the view when scrolling is finished
duration-> Number of milliseconds to use for the scroll

Note: From API 11.

HandlerExploit's answer was what I was looking for, but My listview is quite lengthy and also with alphabet scroller. Then I found that the same function can take other parameters as well :)

Edit:(From AFDs suggestion)

To position the current selection:

int h1 = mListView.getHeight();
int h2 = listViewRow.getHeight();

mListView.smoothScrollToPositionFromTop(position, h1/2 - h2/2, duration);  

Put your code in handler as follows,

public void timerDelayRunForScroll(long time) {
        Handler handler = new Handler(); 
        handler.postDelayed(new Runnable() {           
            public void run() {   
                try {
                    lstView.smoothScrollToPosition(YOUR_POSITION);
                } catch (Exception e) {}
            }
        }, time); 
    }

and then call this method like,

timerDelayRunForScroll(100);

CHEERS!!!

The Listview scroll will be positioned to top by default, but want to scroll if not visible then use this:

if (listView1.getFirstVisiblePosition() > position || listView1.getLastVisiblePosition() < position)
            listView1.setSelection(position);
