Please don't give me negative points and please help me.

Assuming you need to only show one full item at a time and 2 partial items at both the sides. You can use snaphelper to snap recylerview to nearest item position for having the desired effect. And change the width of your item inside the recycler view in the following way. You need to pass the recyclerView reference inside your adapter to get the width.

@Override

protected void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);

    setContentView(R.layout.activity_main);



    recyclerView = findViewById(R.id.recyclerView);

    recyclerView.setLayoutManager(new LinearLayoutManager(this, LinearLayoutManager.HORIZONTAL, false));

    final SnapHelper snapHelper = new PagerSnapHelper();

    snapHelper.attachToRecyclerView(recyclerView);

}

and in your onCreateViewHolder change the width of your item.

public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int i) {

    final View view =

            LayoutInflater.from(parent.getContext())

                    .inflate(R.layout.your_view, parent, false);

    // recyclerView is your passed view.

    int width = recyclerView.getWidth();

    ViewGroup.LayoutParams params = view.getLayoutParams();

    params.width = (int)(width * 0.8);

    view.setLayoutParams(params);

    return new YourViewHolder(view);

}
