How to Run a Recicle View on Other Activities

How do I put a recycle view or a list view into some other activity?

Example: I created a project with name X in it as soon as I put the layout as Empty activity and so it generates an activity_main layout and a standard MainActivity class, dai blz if I create other example layouts b activity and class B, everything that squeezes into class B so that it shows in layout B does not appear. What should I do?

Look at main:

public class MainActivity extends AppCompatActivity {

    private RecyclerView recyclerView;
    private MyAdapter adapter;
    private List<RecyclerItem> listItems;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        recyclerView = (RecyclerView) findViewById(R.id.recyclerView);
        recyclerView.setHasFixedSize(true);
        recyclerView.setLayoutManager(new LinearLayoutManager(this));

        listItems = new ArrayList<>();
        //Generate sample data

        for (int i = 0; i<10; i++) {
            listItems.add(new RecyclerItem("Item " + (i + 1), "teste " + (i+1)));
        }

        //Set adapter
        adapter = new MyAdapter(listItems, this);
        recyclerView.setAdapter(adapter);
    }
}
