如何将RecyclerView上的最后一项滚动到顶部？

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

// 获取最后一项的位置
int lastPosition = recyclerView.getAdapter().getItemCount() - 1;

// 滚动到最后一项并将其置于顶部
layoutManager.scrollToPositionWithOffset(lastPosition, 0);

import android.os.Bundle;
import androidx.appcompat.app.AppCompatActivity;
import androidx.recyclerview.widget.LinearLayoutManager;
import androidx.recyclerview.widget.RecyclerView;

public class MainActivity extends AppCompatActivity {

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

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

        // 设置适配器
        MyAdapter adapter = new MyAdapter(getData());
        recyclerView.setAdapter(adapter);

        // 获取最后一项的位置
        int lastPosition = adapter.getItemCount() - 1;

        // 滚动到最后一项并将其置于顶部
        recyclerView.post(() -> layoutManager.scrollToPositionWithOffset(lastPosition, 0));
    }

    private List<String> getData() {
        List<String> data = new ArrayList<>();
        for (int i = 1; i <= 100; i++) {
            data.add("Item " + i);
        }
        return data;
    }
}
