本文介绍了一个使用 Android ViewPager 和 Fragment 的示例应用。通过创建一个包含多个 Fragment 的 ViewPager，演示了如何初始化 Fragment 列表并设置适配器以实现页面滑动效果。

package com.example.zhangt.fragmenttwo.Fragement;

import android.os.Bundle;
import android.support.annotation.Nullable;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;
import android.support.v4.view.ViewPager;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

import com.example.zhangt.fragmenttwo.R;

import java.util.ArrayList;

/**

public class One extends Fragment {

    private ViewPager pa;
    private ArrayList<Fragment> fragmentList = new ArrayList<Fragment>();

    @Nullable
    @Override
    //找控件      //设置适配器
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.one, null);
        pa = (ViewPager) view.findViewById(R.id.viewpager);
        //添加Fragment
        initFragment();
        //设置适配器
         pa.setAdapter(new fadapter(getChildFragmentManager()));
        return view;
    }

    private void initFragment() {
        Six six = new Six();
        fragmentList.add(six);
    }


    //逻辑代码
    public void onActivityCreated(@Nullable Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);
    }
    class fadapter extends FragmentPagerAdapter{

        public fadapter(FragmentManager fm) {
            super(fm);
        }

        @Override
        public Fragment getItem(int position) {
            return  fragmentList.get(position);
        }

        @Override
        public int getCount() {
            return fragmentList.size();
        }
    }

}
