I want to set android:scaleType attribute to a viewpager to scale the images of a viewpager. But i cannot find the attribute within ViewPager. Is there any other similar attribute which I can use. I even tried a third party viewpager, but didnt work. Pls help and thanks in advance.

Leave your ViewPager as is. Build a custom adapter (extending PagerAdapter) for your ViewPager, where you inflate a certain view for every position. This certain view will hold an ImageView, and you'll pass your image to this ImageView in the adapter's following method:

@Override
public View instantiateItem(ViewGroup container, int position) {
    View view = mInflater.inflate(R.layout.pager_item_with_image, container, false);
    ((ImageView) view.findViewById(R.id.my_image_view)).setImageResource(mImages[position]);

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

And this might be your adapter's constructor with the needed variables:

LayoutInflater mInflater;
private static final int[] mImages;
static {
    mImages = new int[]{
            R.drawable.img1,
            R.drawable.img2,
            R.drawable.img3,
            R.drawable.img4,
            R.drawable.img5,
    };
}

public MyViewPagerAdapter(Context context) {
    mInflater = LayoutInflater.from(context);
}

You can use ImageView and set android:scaleType there. And for ViewPager you should have your PagerAdapter and inflate xml with ImageView
