本文介绍了如何在Android中使用ViewPager同时实现自动轮播和用户手动滑动切换页面的详细步骤，覆盖了.java代码和对应的布局.xml文件配置。

下面的代码同时实现了自动切换和手动切换，先把代码贴上

第一段是适配器

<pre name="code" class="html">package com.example.bean;

import java.util.List;


import android.support.v4.view.PagerAdapter;
import android.support.v4.view.ViewPager;
import android.view.View;
import android.view.ViewGroup;

public class MyPagerAdapter extends PagerAdapter {
	List<View> views;
	
	public MyPagerAdapter(List<View> views)
	{
		this.views=views;
	}
	@Override
	public int getCount() {
		// TODO Auto-generated method stub
		return views==null ? 0 : views.size();
	}

	@Override
	public boolean isViewFromObject(View arg0, Object arg1) {
		
		return arg0==arg1;
	}
	@Override
	public Object instantiateItem(ViewGroup container, int position) {
		
		ViewPager vp=(ViewPager)container;
		View v=views.get(position);
		vp.addView(v);
		return v;
	}
	@Override
	public void destroyItem(ViewGroup container, int position, Object object) {
		
		ViewPager vp=(ViewPager)container;
		View v=views.get(position);
		vp.removeView(v);
	}

}
