Try it and post output or logcat

private void postInitViewPager() {
    try {
         Class<?> viewpager = ViewPager.class;
            Field scroller = viewpager.getDeclaredField("mScroller");
            scroller.setAccessible(true);
            Field interpolator = viewpager.getDeclaredField("sInterpolator");
            interpolator.setAccessible(true);

            mScroller = new ScrollerCustomDuration(getContext(),
                    (Interpolator) interpolator.get(null));
            Log.d("TAG", "mScroller is: " + mScroller + ", "
                + mScroller.getClass().getSuperclass().getCanonicalName() + "; this class is "
                + this + ", " + getClass().getSuperclass().getCanonicalName());
            scroller.set(this, mScroller);
    } catch (Exception e) {
        Log.e("MyPager", e.getMessage());
    }
