issues regarding blur and highlight code onPageScrolled ?

[engr-erum]

@clkasd pls look into this issue
i just change your code to SmartFragmentStatePagerAdapter and then write as it is code of all your adapter class in my class but this is strange now my blur and highlight effects are not working in onPageScroll while onPageScroll listener is getting called but its not producing desired result . how to resolve ?

here is th code :

package com.example.carouselViewProject;

import java.util.ArrayList;

import android.content.Context;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.view.ViewPager.OnPageChangeListener;

import android.widget.Toast;

import com.nineoldandroids.view.ViewHelper;
