title: Jump to the next fragment on any fragment in FragmentStatePagerAdapter
body: <p>I am using a FragmentStatePagerAdapter in my app.
  this is my adapter:</p>
  
  <pre><code>private class ScreenSlidePagerAdapter extends FragmentStatePagerAdapter {
      List&lt;FeedItem&gt; posts = FeedListFragment.getPosts();
  
      public ScreenSlidePagerAdapter(FragmentManager fragmentManager) {
          super(fragmentManager);
      }
  
      @Override
      public Fragment getItem(int position) {
          FeedItem post = posts.get(position);
          String url = post.getUrl();
          String title = post.getTitle();
          String imagUrl = null;
          if (post.getType() == FeedItem.ARTICLE_VIEW_TYPE) {
              imagUrl = posts.get(position).getArticle().getImageUrl();
          }
          ScreenSlidePageFragment fragment = new ScreenSlidePageFragment(url, title, imagUrl);
          fragment.setPostsFragmentOnItemClickListener(PostActivity.this);
          return fragment;
      }
  
      @Override
      public int getCount() {
          return posts.size();
      }
  }
  </code></pre>
  
  <p>What I need is to jump to a specific position in this adapter and also the ability to jump to the next and prev view.
  How can I do that?
  Thanks!</p>
