Recyclerview with twitter fabric

Question

I'm trying to implement RecyclerView with twitter fabric layout, I'm able to fetch in twitter timeline in Activity onCreate function but it is not being displayed.

public class TweetsActivity extends AppCompatActivity {

    private RecyclerView listTweetView;
    private TweetTimelineListAdapter listAdapter;
    private TweetAdapter mTweetAdapter;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_tweets);

        listTweetView = (RecyclerView) findViewById(R.id.list_tweet_view);
        listTweetView.setLayoutManager(new LinearLayoutManager(getApplication()));

        mTweetAdapter = new TweetAdapter(getApplication());
        listTweetView.setAdapter(mTweetAdapter);


        final TwitterApiClient twitterApiClient = TwitterCore.getInstance().getApiClient();
        final StatusesService statusesService = twitterApiClient.getStatusesService();
        final TwitterSession session = Twitter.getSessionManager().getActiveSession();
        statusesService.userTimeline(session.getId(), null, null, null, null, null, null, null, null,
                new Callback<List<Tweet>>() {
                    @Override
                    public void success(Result<List<Tweet>> listResult) {
//                        Log.i(TWITTER_USER_TIMELINE_REQUEST, "Successfully retrieved tweets");
//                        TODO Handle empty list
                        Log.d("TweetActivity", "Total tweet count" + listResult.data.size());
                        if (listResult.data != null ){
                            mTweetAdapter.setTweets(listResult.data);
                        }else{

                        }

                    }

                    @Override
                    public void failure(TwitterException e) {
                    }
                });
    }

    public void setListAdapter(TweetTimelineListAdapter listAdapter) {
        this.listAdapter = listAdapter;
    }
}

My Adapter looks like this

public class TweetAdapter extends RecyclerView.Adapter<TweetAdapter.ViewHolderTweet> {

    private LayoutInflater layoutInflater;
    private List<Tweet> mListTweet ;
    private ImageLoader mImageLoader;


    public TweetAdapter(Context context){

        layoutInflater=LayoutInflater.from(context);
    }

    public TweetAdapter() {}

    @Override
    public ViewHolderTweet onCreateViewHolder(ViewGroup parent, int viewType) {

        View  view = layoutInflater.inflate(R.layout.content_tweets, parent, false);
        ViewHolderTweet viewHolderTweet = new ViewHolderTweet(view);
        return viewHolderTweet;
    }

    public void setTweets(List<Tweet> mListTweet) {
        this.mListTweet = mListTweet;
        //update the adapter to reflect the new set of movies
        notifyDataSetChanged();
    }


    @Override
    public void onBindViewHolder(ViewHolderTweet holder, int position) {
        Tweet currentTweet = mListTweet.get(position);

        //Set user details
        User user = currentTweet.user;
        holder.mUserName.setText(user.name);
        holder.mUserHandle.setText(user.screenName);
        loadImages(user.profileImageUrl, holder);

        //retrieved date may be null
//        String createdAt = currentTweet.createdAt;

        holder.mRetweetCount.setText(currentTweet.retweetCount);
        holder.mFavCount.setText(currentTweet.favoriteCount);
        holder.mTweet.setText(currentTweet.text);

//        mPreviousPosition = position;


    }

    private void loadImages(String urlThumbnail, final ViewHolderTweet holder) {
        if (!urlThumbnail.equals(Constants.NA)) {
            mImageLoader.get(urlThumbnail, new ImageLoader.ImageListener() {

                @Override
                public void onErrorResponse(VolleyError error) {

                }

                @Override
                public void onResponse(ImageLoader.ImageContainer response, boolean isImmediate) {
                    holder.mProfilePic.setImageBitmap(response.getBitmap());
                }
            });
        }
    }

    @Override
    public int getItemCount() {

        return mListTweet.size();
    }

    static class ViewHolderTweet extends RecyclerView.ViewHolder {

        private ImageView mProfilePic;
        private TextView mTweet;
        private TextView mRetweetCount;
        private TextView mFavCount;
        private TextView mUserName;
        private TextView mUserHandle;


        public ViewHolderTweet(View itemView) {
            super(itemView);

            mProfilePic = (ImageView) itemView.findViewById(R.id.iv_user_image);
            mTweet = (TextView) itemView.findViewById(R.id.tv_user_tweet);
            mRetweetCount = (TextView) itemView.findViewById(R.id.tv_retweet_count);
            mFavCount = (TextView) itemView.findViewById(R.id.tv_fav_count);
            mUserName = (TextView) itemView.findViewById(R.id.tv_user_name);
            mUserHandle = (TextView) itemView.findViewById(R.id.tv_user_handle);


        }
    }

}

The layout activity_tweet.xml

<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:fitsSystemWindows="true"
    tools:context=".activity.TweetsActivity">

    <android.support.design.widget.AppBarLayout
        android:id="@+id/appbar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:paddingTop="@dimen/appbar_padding_top"
        android:theme="@style/AppTheme.AppBarOverlay">

        <android.support.design.widget.TabLayout
            android:id="@+id/tabs"
            android:layout_width="match_parent"
            android:layout_height="wrap_content" />

    </android.support.design.widget.AppBarLayout>

    <android.support.v7.widget.RecyclerView
        android:id="@+id/list_tweet_view"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:scrollbars="vertical" />

    <!--<include layout="@layout/content_tweets" />-->

</android.support.design.widget.CoordinatorLayout>

Any direction would appreciated.

Did you call the setLayoutManager after setting the adapter?

            // Set layout manager to position the items
            listTweetView.setLayoutManager(new LinearLayoutManager(getApplication());
