public class ImageAdapter extends PagerAdapter {

        Context context;

        private int[] GalImages = new int[] {
                R.drawable.slider,

            this.context=context;
        }

        @Override
        public int getCount() {
         return GalImages.length;
         //   return 10;
        }

        @Override
        public boolean isViewFromObject(View view, Object object) {
            return view == ((ImageView) object);
        }

        @Override
        public Object instantiateItem(ViewGroup container, int position) {
            ImageView imageView = new ImageView(context);
            imageView.setScaleType(ImageView.ScaleType.FIT_XY);
            imageView.setImageResource(GalImages[position]);
            new LoadImage(imageView).execute("http://www.gadgetbaazar.com/wp-content/uploads/2016/12/Top-Mobile-Phones.jpg");

        }

        @Override
        public void destroyItem(ViewGroup container, int position, Object object) {
            ((ViewPager) container).removeView((ImageView) object);
        }



        private class LoadImage extends AsyncTask<String, String, Bitmap> {
            ImageView img=null;
            public LoadImage(ImageView img){
                this.img=img;
            }
            @Override
            protected void onPreExecute() {
                super.onPreExecute();

            }
            protected Bitmap doInBackground(String... args) {
                Bitmap bitmap=null;
                try {
                    bitmap = BitmapFactory.decodeStream((InputStream)new URL(args[0]).getContent());
                } catch (Exception e) {
                    e.printStackTrace();
                }
                return bitmap;
            }
            protected void onPostExecute(Bitmap image) {
                if(image != null){
                    img.setImageBitmap(image);

Try this

@Override
        public Object instantiateItem(ViewGroup container, int position) {
            ImageView imageView = new ImageView(context);
            imageView.setScaleType(ImageView.ScaleType.FIT_XY);
            if(position == 0){
            imageView.setImageResource(GalImages[position]);
            }else if(position == 1){
            new LoadImage(imageView).execute("http://www.gadgetbaazar.com/wp-content/uploads/2016/12/Top-Mobile-Phones.jpg");
            }else if(position ==2){
            new LoadImage(imageView).execute("https://pisces.bbystatic.com/BestBuy_US/store/ee/2015/com/pm/nav_desktops_1115.jpg");
            }

            container.addView(imageView, 0);
            return imageView;
        }
