Recyclerview项目中出现意外空间-Unexpectedspaceiscominginrecyclerviewitems

This is silly problem but I could not find what I am doing wrong.

这是一个愚蠢的问题，但我找不到我做错了什么。

I am using FirebaseRecyclerAdapter to fill recyclerView but there is unexpected space is coming with items.

我正在使用FirebaseRecyclerAdapter来填充recyclerView，但是项目会出现意想不到的空间。

Fragment class:

片段类：

    @Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.fragment_tags, container, false);

    mProgressBar = (ProgressBar)view.findViewById(R.id.progressBar);
    mTagsRecyclerView = (RecyclerView) view.findViewById(R.id.tagsRecyclerView);
    mLinearLayoutManager = new LinearLayoutManager(getContext());

    mFirebaseDatabaseReference = FirebaseDatabase.getInstance().getReference();
    mFirebaseAdapter = new FirebaseRecyclerAdapter(
            Tags.class,
            R.layout.item_message,
            TagsViewHolder.class,
            mFirebaseDatabaseReference.child("tags")) {

        @Override
        protected void populateViewHolder(TagsViewHolder viewHolder, Tags tags, int position) {
            mProgressBar.setVisibility(ProgressBar.INVISIBLE);
            viewHolder.tagTextView.setText(tags.getTagname());
            viewHolder.usrTextView.setText(tags.getUserid());
        }
    };


    mFirebaseAdapter.registerAdapterDataObserver(new RecyclerView.AdapterDataObserver() {
        @Override
        public void onItemRangeInserted(int positionStart, int itemCount) {
            super.onItemRangeInserted(positionStart, itemCount);
        }
    });

    mTagsRecyclerView.setLayoutManager(mLinearLayoutManager);
    mTagsRecyclerView.setAdapter(mFirebaseAdapter);

    mTagsRecyclerView.addOnItemTouchListener(new RecyclerViewItemClickListener(getContext(),
            new RecyclerViewItemClickListener.OnItemClickListener() {
                @Override public void onItemClick(View v, int position) {
                    //TODO:
                    // do something on item click
                    Log.d("Item clicked at",Integer.toString(position));
                }
            }));
    return view;
}
