title: Firebase how to block specific node in DB
body: <p>I have a RecyclerView that gets updated each time something is changed in firebase database.
  In my database, I have "posts" node and some children inside such as "likes", "comments" and so on.</p>
  
  <p>My loadRecyclerView function :</p>
  
  <pre><code>    private void loadRecyclerViewData() {
      databaseReference.addValueEventListener(new ValueEventListener() {
          @Override
          public void onDataChange(DataSnapshot dataSnapshot) {
              if (posts.size() &gt; 0) {
                  posts.clear();
              }
  
              for (DataSnapshot ds : dataSnapshot.getChildren()) {
                  Post post = ds.getValue(Post.class);
                  //Getting a specific user's information (nickname purposes)
                      posts.add(0, post);
  
              }
              adapter.notifyDataSetChanged();
          }
          @Override
          public void onCancelled(DatabaseError databaseError) {
  
          }
      });
  }
  </code></pre>
  
  <p>My code works and everything gets updated on every change in Firebase, but I would like to keep the listener on everything EXCEPT new post (I made a scroll up to refresh for that).
  Any ideas ??</p>
