RecyclerView decorator adding extra padding on refresh

Question

So, I\'m facing a weird problem while implementing RecyclerView in my project. I have a custom decorator to implement a consistent top and bottom padding and a rather different

Apparently you are adding various decorations. I was having the same problem. What I did here and that worked out was:

1º - Declare the decoration before the onCreate () method:

public StickyHeaderDecoration mDecor;
public MyAdapterPinned MyAdapterPinned;

2º - Then I created a method that creates and populates my recycleview. In this method I check if I have already called mDecor. If so, I remove it. Otherwise, I create it. The code looks like this:

public void createRecyclerView(){
    //hide layout com progress
    hideLayoutProgressFull();

    LinearLayoutManager mLayoutManager = new 
    LinearLayoutManager(getContext(), LinearLayoutManager.VERTICAL, false);
    recyclerView.setLayoutManager(mLayoutManager);

    recyclerView.setItemAnimator(new DefaultItemAnimator());

    myAdapterPinned = new MyAdapterPinned(getContext(), mList);

    recyclerView.setAdapter(myAdapterPinned);

    if (mDecor != null)
        recyclerView.removeItemDecoration(mDecor);

    mDecor = new StickyHeaderDecoration(myAdapterPinned);
    recyclerView.addItemDecoration(mDecor);

    //hide progressDialog
    hideProgress();
}    

NOTE: I am using an adapter that sets the title to each change but you can not interfere with the result. You can use your ordinary adapter. It worked for me. I hope it works for you too;
