给我提供一份Fragment+viewpager2的java demo源码

好的，以下是一个简单的Fragment viewpager2的java demo源码：

import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

import androidx.annotation.NonNull;
import androidx.annotation.Nullable;
import androidx.fragment.app.Fragment;
import androidx.viewpager2.widget.ViewPager2;

import java.util.ArrayList;
import java.util.List;

public class MyFragment extends Fragment {

    private ViewPager2 viewPager;
    private MyAdapter adapter;
    private List<String> data;

    @Nullable
    @Override
    public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment_view_pager, container, false);

        // 初始化ViewPager2和数据
        viewPager = view.findViewById(R.id.viewPager2);
        data = new ArrayList<>();
        data.add("Page 1");
        data.add("Page 2");
        data.add("Page 3");

        // 设置ViewPager2的adapter
        adapter = new MyAdapter(data);
        viewPager.setAdapter(adapter);

        return view;
    }
}

注意：本段代码仅供参考，需要根据实际情况进行修改和优化。
