How to open fragment from RecyclerView Adapter?

Question

I would like to pass data from adapter to my fragment, so basically when i try to click an item, The fragment should open, but, my app did nothing. so how can i solve this?

Adapter

public class CatAdapter extends RecyclerView.Adapter<CatAdapter.ViewHolder> {

    private static String TAG = "Cat Adapter";

    private ArrayList<String> catUrlImage = new ArrayList<>();
    private ArrayList<String> cuteCatName = new ArrayList<>();
    private Context catContext;
    private FragmentManager fragmentManager;
    private OnRecyclerViewItemClickListener listenerthis;


    public CatAdapter(ArrayList<String> catUrlImage, ArrayList<String> cuteCatName, Context catContext, OnRecyclerViewItemClickListener listener) {
        this.catUrlImage = catUrlImage;
        this.cuteCatName = cuteCatName;
        this.catContext = catContext;
        this.listenerthis = listener;
    }

    @Override
    public ViewHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
        View v = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.layout_item, viewGroup, false);
        ViewHolder catViewHolder = new ViewHolder(v);


        return catViewHolder;
    }

    @Override
    public void onBindViewHolder(final ViewHolder viewHolder, final int position) {
        Log.d(TAG, "OnBinding: called");

        Glide.with(catContext)
                .asBitmap()
                .load(catUrlImage.get(position))
                .into(viewHolder.catImage);

        viewHolder.catName.setText(cuteCatName.get(position));

        viewHolder.catItemLayout.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Toast.makeText(catContext, cuteCatName.get(position), Toast.LENGTH_SHORT).show();
                listenerthis.onClick(position);
            }
        });
    }

    @Override
    public int getItemCount() {
        return catUrlImage.size();
    }

    public class ViewHolder extends RecyclerView.ViewHolder {

        CircleImageView catImage;
        TextView catName;
        RelativeLayout catItemLayout;


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

            catImage = itemView.findViewById(R.id.iLikeCat);
            catName = itemView.findViewById(R.id.catVeryCuteName);
            catItemLayout = itemView.findViewById(R.id.cat_container);

        }
    }

    public interface OnRecyclerViewItemClickListener{
        void onClick(int parameter);
    }

}

i already change my Activity before the post so it more changing the onRecycleViewOnItemClickListener

MainActivity

public class MainActivity extends BaseActivity implements CatAdapter.OnRecyclerViewItemClickListener{
    private static final String TAG = "MainActivity";

    private ArrayList<String> catArray = new ArrayList<>();
    private ArrayList<String> catArrayImageUrl = new ArrayList<>();
    DataCat dataCat = new DataCat();

    private RecyclerView recyclerView;
    private RecyclerView.Adapter rAdapter;
    private RecyclerView.LayoutManager rLayoutManager;
    GalleryFragment galleryFragment = new GalleryFragment();

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Log.d(TAG, "Cat Has Create OnCreated");
        findView();
        initView();
        catData();
    }

    private void catData() {
        Log.d(TAG, "Preparing A Bitmap for a Cat");
        for (int i = 0; i < dataCat.catUrl.length; i++) {
           catArrayImageUrl.add(dataCat.catUrl[i]);
           catArray.add(dataCat.catName[i]);
        }

        initRecycleView();

    }

    private void initRecycleView() {
        CatAdapter catAdapter = new CatAdapter(catArrayImageUrl, catArray, this, this);
        recyclerView.setAdapter(catAdapter);
        recyclerView.setLayoutManager(new LinearLayoutManager(this));
    }

    @Override
    public void findView() {
        Log.d(TAG, "initRecylce Vieq");
        recyclerView = findViewById(R.id.recyclerViewList);
        rLayoutManager = new LinearLayoutManager(this);

    }

    @Override
    public void initView() {

    }

    @Override
    public void initListener() {
        recyclerView.setHasFixedSize(true);
    }

    @Override
    public void onClick(int parameter) {
            getSupportFragmentManager().beginTransaction()
                    .replace(R.id.container_galery, galleryFragment)
                    .addToBackStack(null)
                    .commit();
    }
}

I input some layout maybe there some bad structure on my layout

activity_main

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context=".activity.MainActivity">


<android.support.v7.widget.RecyclerView
    android:id="@+id/recyclerViewList"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical" />

<FrameLayout
    android:id="@+id/container_galery"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

</LinearLayout>    

i've already try the solutions from the comment bellow and my fragment still not showing up. I didnt get any error from my logCat, when i try to click.

Do two small changes in your code-

Adapter

public CatAdapter(ArrayList<String> catUrlImage, ArrayList<String> cuteCatName, Context catContext, OnRecyclerViewItemClickListener listenerthis) {
    this.catUrlImage = catUrlImage;
    this.cuteCatName = cuteCatName;
    this.catContext = catContext;
    this.listenerthis = listenerthis;
}

MainActivity

private void initRecycleView() {
    CatAdapter catAdapter = new CatAdapter(catArrayImageUrl, catArray, this, this);
    recyclerView.setAdapter(catAdapter);
    recyclerView.setLayoutManager(new LinearLayoutManager(this));
}

thats it. Hope it will be helpful.
