• 创建Adapter继承InfinitePagerAdapter

public class MyAdapter extends InfinitePagerAdapter {

    private List<String> data;

    public MyAdapter(List<String> data) {
        this.data = data;
    }

    @Override
    public int getItemCount() {
        return data == null ? 0 : data.size();
    }

    @Override
    public View getItemView(int position, View convertView, ViewGroup container) {
        return your view;
    }
}

• 设置ViewPager Adapter

@Override
protected void onCreate(Bundle savedInstanceState) {
    AutoScrollViewPager mViewPager = (AutoScrollViewPager) findViewById(R.id.viewPager);
    MyAdapter mAdapter = new MyAdapter(data);
    mViewPager.setAdapter(mAdapter);
    // optional start auto scroll
    mViewPager.startAutoScroll();
}
