Custom Adapter of ListView

My ListView have multiple items. Each Item have a TextView and two ImageView. I have implemented this by using custom adapter. Each ImageView in my ListView have 5 images. How can i show 5 images repeatedly in a ImageView in custom adapter? I want to repeat the images in all ImageView in the interval of 15 seconds. 

public class CategoryAdapter extends BaseAdapter {
    public Activity adapterActivity;
    LayoutInflater adapterInflater;
    ImageLoader compImageLoader;
    List<Categary> list;

    ArrayList<String> category = new ArrayList<String>();
    ArrayList<String> leftImage = new ArrayList<String>();
    ArrayList<String> rightImage = new ArrayList<String>();

    public CategoryAdapter(Activity activity, List<Categary> listData) {
        list = listData;
        adapterActivity = activity;
        adapterInflater = (LayoutInflater) adapterActivity
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        compImageLoader = new ImageLoader(
                adapterActivity.getApplicationContext());
    }

    @Override
    public int getCount() {
        // TODO Auto-generated method stub
        return list.size();
    }

    @Override
    public Object getItem(int position) {
        return position;
    }

    @Override
    public long getItemId(int position) {
        return position;
    }

    public class ViewHolder {
        public ImageView lPic, rPic;
        public TextView category;
    }

    @Override
    public View getView(final int position, View convertView, ViewGroup parent) {

        View vi = convertView;
        final ViewHolder holder;
        if (vi == null) {

            vi = adapterInflater.inflate(R.layout.categoryadapter, null);
            holder = new ViewHolder();
            holder.lPic = (ImageView) vi.findViewById(R.id.imageView1);
            holder.rPic = (ImageView) vi.findViewById(R.id.imageView2);
            holder.category = (TextView) vi
                    .findViewById(R.id.textView_category);
            vi.setTag(holder);
        } else {
            holder = (ViewHolder) vi.getTag();
        }
        final Categary assingValue = list.get(position);
        holder.lPic.setTag(assingValue.leftPicture);
        holder.rPic.setTag(assingValue.rightPicture);
        holder.category.setText(assingValue.id);
        compImageLoader.DisplayImage(assingValue.leftPicture, holder.lPic);
        compImageLoader.DisplayImage(assingValue.rightPicture, holder.rPic);
        return vi;
    }          
}

The AnimationDrawable is the right component for that:

In your getView(), I assume you have an ImageView named imageView. I also assume you have an array of Drawables representing your images:

AnimationDrawable animation = new AnimationDrawable();
for (Drawable image : images) {
    animation.addFrame(image, 15 * 1000L);
}
imageView.setImageDrawable(animation);
animation.start();

This can change depending on how your images are available in your application.

let's say that you have the ids of your images in an array.

int i=0;
new CountDownTimer(15000, 1000) {

    @Override
    public void onTick(long millisUntilFinished) {
        // TODO Auto-generated method stub

    }

    @Override
    public void onFinish() {
        imgView.setImageResource(arrayIds[i]);
    i++;
        if(i==arrayIds.length)
            i=0;
        start();//restart the count down timer for another 15 seconds again
    }
}.start();

You can spawn thread in getView function for each ListView item and put delay of 15 sec in between images.

like this:

    final ImageView iv = (ImageView) v.findViewById(R.id.myImageView);
    new Thread(new Runnable() {

        @Override
        public void run() {
            while(true){
                iv.setImageResource(iconID);
                Thread.sleep(15000);
            }
        }
    }).start();
