Android - How to manage position of viewpager in adapter?

I am developing an android app, in it i am displaying a ListView with a number of items. on Click of an item i am passing item name and ArrayList of all items .

Intent myIntent = new Intent(context, DetailActivity.class);
            myIntent.putExtra("name", name);
            myIntent.putStringArrayListExtra("arraylistofitems", arraylistofitems);
            context.startActivity(myIntent);

In DetailActivity, i want to show the clicked items from list and on scroll left or right show the remaining item from the list. I am using following code -

Intent mIntent = getIntent();
    name = mIntent.getStringExtra("name");
    names = mIntent.getStringArrayListExtra("arraylistofitems");
    viewPager = (ViewPager) findViewById(R.id.idofviewpager);
    adapter = new ViewPagerAdapter(context, arraylistofitems);
    viewPager.setAdapter(adapter);

and ViewPagerAdapter looks like following -

public ViewPagerAdapter(Context context,ArrayList<String> data) {
    this.context = context;
    this.data=data;
}

@Override
public int getCount() {
    return data.size();
}

@Override
public boolean isViewFromObject(View view, Object object) {
    return view == ((MyLayout) object);
}

@Override
public Object instantiateItem(ViewGroup container, int position) {

    // item views declaration

    inflater = (LayoutInflater) context
            .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    View itemView = inflater.inflate(R.layout.viewpager_item_id, container,
            false);

    //layout item initialization

    ((ViewPager) container).addView(itemView);

    ParseQuery<ParseObject> query = ParseQuery.getQuery("myclass");
    query.whereEqualTo("colName", data.get(position));
    query.findInBackground(new FindCallback<ParseObject>() {
        @Override
        public void done(List<ParseObject> itemList, ParseException arg1) {
            for (int i = 0; i < itemList.size(); i++) {
                ParseObject po = itemList.get(i);

                //set the values from parse into views
            }
        }
    });


    return itemView;

}

@Override
public void destroyItem(ViewGroup container, int position, Object object) {
    ((ViewPager) container).removeView((MyLayout) object);

}

But all data being shown from starting (0th Position to length of arraylist).

Question - How do i implement scroll effect with clicked item being opened and on scrolling left left items should be display or vice-versa?
