将layout布局转换为view对象。
1>layoutInflater lf=getLayoutInflater().from(this);
lf.inflate(resource,root);
2>View.inflate(context,resource,root);
配置adapter
1>pageradapter 数据源：list<View>
2>FragmentPagerAdapter 数据源：list<Fragment>
3>FragmentStatePagerAdapter 数据源：list<Fragment>

FragmentPagerAdapter
使用fragment作为viewpager的数据源。
