enchantedviewpager

EchantedViewPager is a custom ViewPager that provides some custom and usefull functionalities, such as, scalling scroll, alpha scroll and swipe to dismiss option.

Usage

Inside your pager adapter you must do this whenever you instantiate a view:

@Override
    public Object instantiateItem(ViewGroup container, int position) {
        (...)
        mCurrentView.setTag(EnchantedViewPager.ENCHANTED_VIEWPAGER_POSITION + position);
        container.addView(mCurrentView);

        return mCurrentView;
    }
<com.tiagosantos.enchantedviewpager.EnchantedViewPager
    android:layout_width="match_parent"
    android:layout_height="wrap_content"/>

Scale scroll

 final EnchantedViewPager mViewPager = (EnchantedViewPager) findViewById(R.id.viewpager);
 mViewPager.useScale();

Alpha scroll

 final EnchantedViewPager mViewPager = (EnchantedViewPager) findViewById(R.id.viewpager);
 mViewPager.useAlpha();

Swipe to dismiss

 final EnchantedViewPager mViewPager = (EnchantedViewPager) findViewById(R.id.viewpager);
 mViewPager.addSwipeToDismiss(new EnchantedViewPager.EnchantedViewPagerSwipeListener() {
                        @Override
                        public void onSwipeFinished(int position) {
                            //execute code to remove the swiped item
                        }
                    });

Carrousell / Infinite loop mode

First, your pager adapter must extend EchantedPagerAdapter:
    SomePagerAdapter extends EnchantedViewPagerAdapter
    public SomePagerAdapter(Context context,ArrayList<AlbumArt> albumList) {
        super(albumList);
        (...)
    }
And make sure you don't implement getCount() method, since it must be controlled by EnchantedPagerAdapter.

Then you just need to activate/diasble carrousel mode:
    echantedAdapter.enableCarrousel();
    echantedAdapter.disableCarrousel();
If you want to have carrousel for both sides, you need to set your viewpager position on the middle:
    mViewPager.setCurrentItem(echantedAdapter.getMiddlePosition());
