ViewPager 自动播放主要代码部分（借鉴）

第一步 初始化viewpager

//初始化banner
private void initBannerView(View v) {
    vpBanner = new ArrayList<ImageView>();
    for (int i = 0; i < bannerResource.length; i++) {
        ImageView iv = new ImageView(getActivity());
        iv.setImageResource(bannerResource[i]);
        vpBanner.add(iv);
    }
    vp = (ViewPager) v.findViewById(R.id.vp_banner);
    vp.setAdapter(new BannerAdapter());
}

第二步 初始化 填充数据

//填充banner
class BannerAdapter extends PagerAdapter {
    @Override
    public boolean isViewFromObject(View view, Object o) {
        return view == o;
    }

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

    @Override
    public Object instantiateItem(ViewGroup container, int position) {
        ImageView iv = vpBanner.get(position);
        container.addView(iv);
        return iv;
    }

    @Override
    public void destroyItem(ViewGroup container, int position, Object object) {
        container.removeView((View) object);
    }
}
第四步 去设置每秒切换图片 并提交给UI更新

@Override
public void onStart() {
    super.onStart();
    scheduledExecutorService = Executors.newSingleThreadScheduledExecutor();
    //每隔3秒钟切换一张图片
    scheduledExecutorService.scheduleWithFixedDelay(new ViewPagerTask(), 3, 3, TimeUnit.SECONDS);

}

//切换图片
private class ViewPagerTask implements Runnable {

    @Override
    public void run() {
        // TODO Auto-generated method stub
        currentItem = (currentItem + 1) % bannerResource.length;
        //更新界面
        // handler.sendEmptyMessage(0);
        handler.obtainMessage().sendToTarget();
    }

}

private Handler handler = new Handler() {

    @Override
    public void handleMessage(Message msg) {
        // TODO Auto-generated method stub
        //设置当前页面mViewPager.setCurrentItem(currentItem);
        //Log.d("msg", vp.getCurrentItem() + "");
        vp.setCurrentItem(currentItem);
    }
};
