how to use a ViewPager in a fragment

Question

I download a project about ViewPager and CirclePageIndicator. It works well on my tablet and its code is :

Test1Activity.java:

TestFragmentAdapter mA         


        

Answer 1

Put this code in your MainActivity. The below code will load the Fragment in your Layout.

Step 1

Fragment fragment = new PageSlider();
FragmentManager manager = getSupportFragmentManager();
manager.beginTransaction().replace(R.id.content, fragment).commit();

Next we need to implement the ViewPager

Step 2

public class PageSlider extends Fragment {
public PageSlider() {
// Required empty public constructor
}
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
    return inflater.inflate(R.layout.page_slider, container, false);
}
@Override
public void onViewCreated(View view, Bundle savedInstanceState) {
// TODO Auto-generated method stub
  super.onViewCreated(view, savedInstanceState);
  PagerSlidingTabStrip tab = (PagerSlidingTabStrip) view
.findViewById(com.akshay.protocol10.asplayer.R.id.tabs);

 ViewPager pager=(ViewPager)view  .findViewById(com.akshay.protocol10.asplayer.R.id.view_pager);
MyPagerAdapter adapter = new MyPagerAdapter(getChildFragmentManager());
pager.setAdapter(adapter);
tab.setViewPager(pager);
}
// TODO: Rename method, update argument and hook method into UI event
public void onButtonPressed(Uri uri) {
}
@Override
public void onAttach(Activity activity) {
super.onAttach(activity);
}
@Override
public void onDetach() {
super.onDetach();
}
public interface OnFragmentInteractionListener {
// TODO: Update argument type and name
public void onFragmentInteraction(Uri uri);
}
}

Step 3: Create the Adapter

    public class MyPagerAdapter extends FragmentPagerAdapter {
        private final String[] TITLES = { "Album", "Artist", "Songs", "Genre" };
        public MyPagerAdapter(FragmentManager childFragmentManager) {
      // TODO Auto-generated constructor stub
    super(childFragmentManager);
    }
    @Override
    public CharSequence getPageTitle(int position) {
    // TODO Auto-generated method stub
    return TITLES[position];
    }
    @Override
    public Fragment getItem(int index) {
    // TODO Auto-generated method stub
       Fragment fragment = null;
       if (index == 0) {
       fragment = new Albums();
       } else if (index == 1) {
       fragment = new ArtistFragment();
       } else if (index == 2) {
        fragment = new TracksFragment();
       } else if (index == 3) {
       fragment = new GenreFragment();
      }
     return fragment;
    }

    @Override
    public int getCount() {
    // TODO Auto-generated method stub
    return TITLES.length;
    }
   }
