How To Use A Viewpager In A Fragment

I download a project about ViewPager and CirclePageIndicator. It works well on my tablet and its code is : Test1Activity.java: TestFragmentAdapter mAdapter; ViewPager mPager; @Over

Solution 1:

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

Step 1

Fragmentfragment=newPageSlider();
FragmentManagermanager= getSupportFragmentManager();
manager.beginTransaction().replace(R.id.content, fragment).commit();

Next we need to implement the ViewPager

Step 2

publicclassPageSliderextendsFragment {
publicPageSlider() {
// Required empty public constructor
}
@OverridepublicvoidonCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
}
@OverridepublicViewonCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragmentreturn inflater.inflate(R.layout.page_slider, container, false);
}
@OverridepublicvoidonViewCreated(View view, Bundle savedInstanceState) {
// TODO Auto-generated method stubsuper.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 = newMyPagerAdapter(getChildFragmentManager());
pager.setAdapter(adapter);
tab.setViewPager(pager);
}
// TODO: Rename method, update argument and hook method into UI eventpublicvoidonButtonPressed(Uri uri) {
}
@OverridepublicvoidonAttach(Activity activity) {
super.onAttach(activity);
}
@OverridepublicvoidonDetach() {
super.onDetach();
}
publicinterfaceOnFragmentInteractionListener {
// TODO: Update argument type and namepublicvoidonFragmentInteraction(Uri uri);
}
}

Step 3: Create the Adapter

publicclassMyPagerAdapterextendsFragmentPagerAdapter {
        privatefinal String[] TITLES = { "Album", "Artist", "Songs", "Genre" };
        publicMyPagerAdapter(FragmentManager childFragmentManager) {
      // TODO Auto-generated constructor stubsuper(childFragmentManager);
    }
    @Overridepublic CharSequence getPageTitle(int position) {
    // TODO Auto-generated method stubreturn TITLES[position];
    }
    @Overridepublic Fragment getItem(int index) {
    // TODO Auto-generated method stubFragmentfragment=null;
       if (index == 0) {
       fragment = newAlbums();
       } elseif (index == 1) {
       fragment = newArtistFragment();
       } elseif (index == 2) {
        fragment = newTracksFragment();
       } elseif (index == 3) {
       fragment = newGenreFragment();
      }
     return fragment;
    }

    @OverridepublicintgetCount() {
    // TODO Auto-generated method stubreturn TITLES.length;
    }
   }

Solution 2:

Android does not support fragments inside of fragments. Either switch your ViewPager to use a PagerAdapter that does not use fragments, or do not put the ViewPager in a fragment.

EDIT:

Now, Android supports fragments inside fragments by using Fragment.getChildFragmentManager() . Have a look at this answer.

Solution 3:

Have you try to replace extends Fragment by extends android.support.v4.app.Fragment ?

When you do this, getFragmentManager() refers to android.support.v4.app.FragmentManager.

Solution 4:

Check the fragment extends class it should be imported from android.support.v4.app.Fragment Not android.app.Fragment
