如何在Android中实现Infitine View Pager + Tab

Question

I want to implement infinite ViewPager with Tabs(ViewPager Indicator) in android.

I found many sample project,all of which include only ViewPager. I need to integrate infite ViewPager with Tabs.

Some of samples I have found:

1.) https://github.com/antonyt/InfiniteViewPager

2.) https://gitorious.org/thehayro-tutorials/thehayro-tutorials/source/c98c87bdb600d23ddfb195cffb9814097df73555:InifiniteViewPagerExample

Any help or idea will be appreciated.

Answer 1

        **viewpager with indicator  in android using fragment**


        ViewPagerAdapter

        import android.support.v4.app.Fragment;
        import android.support.v4.app.FragmentManager;
        import android.support.v4.app.FragmentPagerAdapter;

        public class ViewPagerAdapter extends FragmentPagerAdapter {
            public ViewPagerAdapter(FragmentManager fm) {
                super(fm);
            }

            @Override
            public int getCount() {
                return 4;
            }

            @Override
            public Fragment getItem(int position) {
                switch (position) {
                    case 0:
                        FragmentAnimation1 fragmentAnimation1 = new FragmentAnimation1();
                        return fragmentAnimation1;

                    case 1:
                        FragmentAnimation2 fragmentAnimation2 = new FragmentAnimation2();
                        return fragmentAnimation2;

                    case 2:
                        FragmentAnimation3 fragmentAnimation3 = new FragmentAnimation3();
                        return fragmentAnimation3;

                    case 3:
                        FragmentAnimation4 fragmentAnimation4 = new FragmentAnimation4();
                        return fragmentAnimation4;
                }
                return null;
            }
        }

    **Activity**

    ViewPager viewPager = (ViewPager) findViewById(R.id.pager);
            viewPager.setAdapter(new ViewPagerAdapter(getSupportFragmentManager()));
