Android: changing Image with time interval

Question

I am using ImageDownloader class to get images from server and getting these images links using an ArrayList. After downloading the Image I am setting the Image

Answer 1

Set up your ImageView like this:

You can Use TimerTask to achieve this.

// Declaration and Initialization :

List mImageUrl = new ArrayList();
private ImageLoader mImageLoader =  new ImageLoader(MainActivity.this);
Timer timer = new Timer(); // changed
int i = 0;

// Put this code in your onCreate :

timer.scheduleAtFixedRate(new TimerTask() {

            @Override
            public void run() {
                if (i < mImageUrl.size()) {
                    runOnUiThread(new Runnable() {
                        @Override
                        public void run() {
                            // TODO Auto-generated method stub
                            mImageLoader.DisplayImage(mImageUrl.get(i), img);
                            i++;
                        }
                    });
                } else {
                    i = 0;
                }
            }
        }, 0, 2000);

The timer task will start in 0 seconds and it will change the background every 2 seconds. You can change this as like as you want. Its working fine. I have tested.

You can read more about the timertask here.

You can also cancel the timer with the help of timer.cancel() HIH.
