FragmentにHandlerを追加するには:

	private static class BannerHandler extends Handler {
		@Override
		public void handleMessage(Message msg) {
			if (msg.what == MSG_SWITCH_PIC) {
				if (vpBanner != null) {
					if (switchPictureAdapter != null) {
						vpBanner.setCurrentItem(vpBanner.getCurrentItem() + 1);
						this.sendEmptyMessageDelayed(MSG_SWITCH_PIC,
								BANNER_TIME_PEROID);
					}
				}
			}
		}
	}

初期化:

bannerHandler = new BannerHandler();
		bannerHandler.sendEmptyMessageDelayed(MSG_SWITCH_PIC,
				BANNER_TIME_PEROID);
	
		mImgUrls.clear();
		mImgUrls.add("https://www.baidu.com/img/bd_logo1.png");
		mImgUrls.add("https://www.baidu.com/img/bd_logo1.png");
		mImgUrls.add("https://www.baidu.com/img/bd_logo1.png");
		switchPictureAdapter = new SwitchPictureAdapter(mActivity, vpBanner,
				mImgUrls, view);
		vpBanner.setAdapter(switchPictureAdapter);
		if (mImgUrls.size() > 1) {
			vpBanner.setCurrentItem(1);
		}

輪番図のアダプタ:

public class SwitchPictureAdapter extends PagerAdapter {
	private Context mContext;
	private List mImageViews;
	private List mImgUrls;
	private LinearLayout mPoints;
	private ViewPager mViewPage;

	public SwitchPictureAdapter(Context mContext, ViewPager page,
			List mImgUrls, View view) {
		super();
		this.mContext = mContext;
		this.mImgUrls = mImgUrls;
		this.mImageViews = new ArrayList();
		this.mViewPage = page;
		this.mPoints = (LinearLayout) view.findViewById(R.id.ll_point);
		mPoints.removeAllViews();
		initData();
		initViews();
		this.mViewPage.setOnPageChangeListener(new PagerListener());
	}

	private void initData() {
		//       ，        
		mImgUrls.add(0, mImgUrls.get(mImgUrls.size() - 1)); //            
		mImgUrls.add(mImgUrls.get(1));//          0 
		//    
		for (int i = 0; i < mImgUrls.size() - 2; i++) {
			ImageView point = new ImageView(mContext);
			int dp = (int) TypedValue.applyDimension(
					TypedValue.COMPLEX_UNIT_DIP, 8, mContext.getResources()
							.getDisplayMetrics());
			LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(
					dp, dp);
			int margin = (int) TypedValue.applyDimension(
					TypedValue.COMPLEX_UNIT_DIP, 4, mContext.getResources()
							.getDisplayMetrics());
			params.setMargins(margin, 0, margin, 0);
			point.setLayoutParams(params);
			if (i == 0) {
				point.setBackgroundResource(R.drawable.point_red);
			} else {
				point.setBackgroundResource(R.drawable.point_normal);
			}
			mPoints.addView(point);
		}
	}

	private void initViews() {
		if (mImgUrls != null) {
			for (int i = 0; i < mImgUrls.size(); i++) {
				ImageView view = new ImageView(mContext);
				view.setLayoutParams(new LayoutParams(
						LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT));
				ImageLoadUtil.loadImage(mImgUrls.get(i), view);
				mImageViews.add(view);
				if (mImgUrls.size() <= 3) {//         
					break;
				}
			}
		}
	}

	@Override
	public Object instantiateItem(ViewGroup container, int position) {
		ImageView view = mImageViews.get(position);
		ViewGroup parent = (ViewGroup) view.getParent();
		if (parent != null) {
			parent.removeAllViews();

	}

	@Override
	public int getCount() {
		if (mImgUrls == null) {
			return 0;
		}
		if (mImgUrls.size() <= 3) {
			return 1;
		}
		return mImgUrls.size();
	}

	@Override
	public boolean isViewFromObject(View arg0, Object arg1) {

		return arg0 == arg1;
	}

	@Override
	public void destroyItem(ViewGroup container, int position, Object object) {
		container.removeView((ImageView) object);
	}

	private class PagerListener implements OnPageChangeListener {
		@Override
		public void onPageScrollStateChanged(int arg0) {
		}

		@Override
		public void onPageScrolled(int arg0, float arg1, int arg2) {

		@Override
		public void onPageSelected(int pos) {
			if (mImageViews.size() > 1) { //          
				if (pos < 1) {
