How to set viewpager to change page automatically after 5 sec

Question

i Want to make a slideshow with viewpager where pages are changed automatically every 5 sec. Ive done the viewpager , but got blocked till here , any advise??

Adapter.class (its inner class in my fragment)

 class CustomPagerAdapter extends PagerAdapter {

    Context mContext;
    LayoutInflater mLayoutInflater;

    public CustomPagerAdapter(Context context) {
        mContext = context;
        mLayoutInflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    }

    @Override
    public int getCount() {
        return mResources.length;
    }

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

    @Override
    public Object instantiateItem(ViewGroup container, int position) {
        View itemView = mLayoutInflater.inflate(R.layout.slide_show_item, container, false);

        ImageView imageView = (ImageView) itemView.findViewById(R.id.imageView);
        imageView.setImageResource(mResources[position]);

        container.addView(itemView);

        return itemView;
    }

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

Here is the function i call in my fragment

 public void setSlideShow(){

    mCustomPagerAdapter = new CustomPagerAdapter(getActivity());

    mViewPager = (ViewPager)rootView.findViewById(R.id.slide_show);
    mViewPager.setAdapter(mCustomPagerAdapter);

}

Well, android does not provide any function to automatically flip views inside ViewPager but it provides you with something called TimerTask class which you can use to achieve your goal. You can look at this link to do it this way.

There is one more easy way to achieve this but for that you will have to drop the idea of using ViewPager. Instead you can use ViewFlipper. ViewFlipper has its own methods to flip automatically. You just need to add these two lines to make your views automatically flippable:

mViewFlipper.setAutoStart(true);
mViewFlipper.setFlipInterval(2000); // flip every 2 seconds (2000ms)

You can get ViewFlipper example here.
