Auto Scrolling of horizontal list items with timer in android

Question

I need to show advertisements in my app with datas fetched from web services. I have displayed the ads in horizontal listview. Now I want each cell of the listview to be scrolled automatically at particular time interval (as like google ads). How can I do this ?

The best way, I think, is to use a handler in your activity, or fragment. Just add the code like this:

private Handler handler = new Handler();
handler.postDelayed(runnable, interval);

and in your runnable you should implement scrolling of your listview.

UPDATE If you will use ViewPager instead of scrollview you can make it this way:

    final Handler handler = new Handler(); 
    Runnable runable = new Runnable() { 

        @Override 
        public void run() {
            //this will select next page number
            page = page==maxPages? 0 : ++page;
            //this will change the page to concrete page number
            viewPager.setCurrentItem(page);
            //this will execute this code after timeInterval
            handler.postDelayed(this, timeInterval);
        } 
    }; 
    handler.postDelayed(runable, timeInterval); 

where viewPager is your ViewPager instance, timeInterval - time interval in milliseconds after which you want to scroll the page, maxPages - number of last page that you have in your ViewPager
