public class ViewPageFragmentAdapter extends FragmentPagerAdapter {

replace this line with

public class ViewPageFragmentAdapter extends FragmentPagerAdapter implements TitleProvider{

You have to implement TitleProvider for your pager adapter if you are using titlePageindicator. you might need to add some functions after implementing this...

to call different children..

@Override
        public Fragment getItem(int arg0) {
            if (arg0 == 0) {
                return new Fragment1();
            } else if (arg0 == 1) {
                return new Fragment2();
            } else if (arg0 == 2){
                return new Fragment3();
            } else {
                return new Fragment0();
            }
        }

i want to put different different views for different viewpage, is it possible? – Jyosna Nov 15 '11 at 08:49
yes possible, you need to check for child index requested, if it matches with that of yours, you supply the fragment that you think is apt at that index. – Yashwanth Kumar Nov 15 '11 at 08:52
can u tell me where i will check the child index? – Jyosna Nov 15 '11 at 09:23
in your pager adapter, you have getItem(int position) , position is the child index. – Yashwanth Kumar Nov 15 '11 at 09:31
ya that i know where i ll use that index. In page adapter or in pageFragment? – Jyosna Nov 15 '11 at 09:54
