Pooja,

The KnowledgeArticleVersion has a field, KnowledgeArticleId, which identifies the article independent of version.  You should be able to use these Ids to query the KnowledgeArticleViewStat records that correspond to the articles.

The code below takes a list of KnowledgeArticleVersion records and returns a map from the KnowledgeArticleVersion ID to the view count for the article:

public static Map<Id,Integer> getKnowledgeArticleViews( List<KnowledgeArticleVersion> list_KAVs )
{
    Map<Id,Id> map_KAID_KAVID = new Map<Id,Id>();

    for ( KnowledgeArticleVersion kav : list_KAVs )
    {
        map_KAID_KAVID.put( kav.KnowledgeArticleId, kav.Id );
    }

    Map<Id,Integer> map_KAVID_ViewCount = new Map<Id,Integer>();

    for ( KnowledgeArticleViewStat kavs :
        [   SELECT  Id, ParentId, ViewCount
            FROM    KnowledgeArticleViewStat
            WHERE   ParentId IN :map_KAID_KAVID.keySet()
        ]
        )
    {
        map_KAVID_ViewCount.put( map_KAID_KAVID.get( kavs.ParentId ), kavs.ViewCount );
    }

    return map_KAVID_ViewCount;
}

You can use this map to populate a list of wrapper class instances that contain all of the information from the KnowledgeArticleVersion records and the view count.  Have your VF page repeat on this list of wrappers and you can display the view counts along with all the other information about the articles.

If you need help with the wrapper class, let me know.  I'll be happy to help.

If this helps, please mark it as a solution, and give kudos (click on the star) if you think I deserve them.  Thanks!
