Sometimes we need to display ads in our application.To display the multiple images one after another in some time interval write the following code:

1. Create a customTimerTask class that extends the TimerTask class

public class customTimerTask extends TimerTask
{
    Context mycontext;
    int i =0;
    public customTimerTask(Context c) {
        mycontext=c;
    }

    @Override
    public void run() {

        advanceSearch.runOnUiThread(new Runnable() {

            public void run() {
                // Display the images
                adImage.setTag(ServerUrl.BASE_SERVER_URL+ServerUrl.AD_UOLAOD_URL+imageArray.get(i).getImagePath());         
                imageLoader.DisplayImage(ServerUrl.BASE_SERVER_URL+ServerUrl.AD_UOLAOD_URL+imageArray.get(i).getImagePath(), advanceSearch, adImage);
                i++;
                if(i >= imageArray.size()){
                    i = 0;
                }
            }
        });
    }
}

2. Then write the below line of code where you want to display images after getting the array of images

if(imageArray != null && imageArray.size() > 0)
{
    Timer timer=new Timer();
    /*
    Schedule a task for repeated fixed-rate execution after a specific delay has passed.
    Parameters
    task  the task to schedule. 
    delay  amount of time in milliseconds before first execution. 
    period  amount of time in milliseconds between subsequent executions. 
    */
    timer.scheduleAtFixedRate(new customTimerTask(advanceSearch),4000,4000);
}

Hope this will help you :)
