android - Disable ViewPager scrolling animation

Question

From the code here, I have a ViewPager that sets an adapter. Is there any way to disable the scrolling animation so that it just "jumps" to the new page when I swipe? I'm not looking to disable the whole scrolling function in onTouchEvent and onInterceptTouchEvent, just the sliding animation.

mSectionsPagerAdapter = new SectionsPagerAdapter(getFragmentManager());

// Set up the ViewPager with the sections adapter.
mViewPager = (CustomViewPager) findViewById(R.id.pager);
mViewPager.setAdapter(mSectionsPagerAdapter);

I do not know if there is a clean solution. But you can use a trick and undo the standard page transformer with another transformer. The NoPageTransformer would look like this:

private static class NoPageTransformer implements ViewPager.PageTransformer {
    public void transformPage(View view, float position) {
        if (position < 0) {
            view.setScrollX((int)((float)(view.getWidth()) * position));
        } else if (position > 0) {
            view.setScrollX(-(int) ((float) (view.getWidth()) * -position));
        } else {
            view.setScrollX(0);
        }
    }
}

To add it to your ViewPager, call:

mViewPager.setPageTransformer(false, new NoPageTransformer());

Will work in SDK version 16 and above.
