ViewPager结合view无限滑动

使用viewPager进无限滑动，这里的实现是在适配器里面进行，当然在外头使用滑动监听也行。 

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

import java.util.ArrayList;

public class ReadViewPagerAdapter extends PagerAdapter 
{
    private ArrayList<View> viewArrayList;

    public ReadViewPagerAdapter(ArrayList<View> viewArrayList) 
    {
        this.viewArrayList = viewArrayList;
    }

    @Override
    public int getCount() 
    {
        return Integer.MAX_VALUE;//实现无限循环播放，这里使用一个极端的数字
    }

    @Override
    public boolean isViewFromObject(View view, Object object) 
    {
        return view == object;
    }

    @Override
    public Object instantiateItem(ViewGroup container, int position) 
    {
        position %= viewArrayList.size(); //防止数组越界
        if (position < 0)
        {
            position = viewArrayList.size() + position;
        }
        View view = viewArrayList.get(position);
        //如果这个view已经被加入到viewPager中，那么就将它移除，不然可能会出现一个view被重复添加而出现错误

        if (view.getParent() != null)
        {
            ViewGroup viewGroup = (ViewGroup) view.getParent();
            viewGroup.removeView(view);
        }
        container.addView(view);
        return view;
    }

    @Override
    public void destroyItem(ViewGroup container, int position, Object object)
    {
//        container.removeView(viewArrayList.get(position));//删除页卡，这个地方不能对其进行重写
    }

}

 以上便实现了对viewPager里面的view进行无限循环切换了
