如何在启动应用程序时自动加载RecyclerView？

// 布局文件中的RecyclerView组件
<androidx.recyclerview.widget.RecyclerView
    android:id="@+id/recyclerView"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

// Java代码中的实现
public class MyAdapter extends RecyclerView.Adapter<MyAdapter.ViewHolder> {
    private List<String> data;

    public MyAdapter(List<String> data) {
        this.data = data;
    }

    @Override
    public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_layout, parent, false);
        return new ViewHolder(view);
    }

    @Override
    public void onBindViewHolder(ViewHolder holder, int position) {
        String item = data.get(position);
        holder.textView.setText(item);
    }

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

    public static class ViewHolder extends RecyclerView.ViewHolder {
        public TextView textView;

        public ViewHolder(View itemView) {
            super(itemView);
            textView = itemView.findViewById(R.id.textView);
        }
    }
}

// 在Activity中的使用
public class MainActivity extends AppCompatActivity {
    private RecyclerView recyclerView;
    private MyAdapter adapter;
    private List<String> data;

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

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

        data = new ArrayList<>();
        data.add("Item 1");
        data.add("Item 2");
        data.add("Item 3");

        adapter = new MyAdapter(data);
        recyclerView.setAdapter(adapter);
    }
}
