    <p>I am trying to create a fragment that would have a ViewPager. When the said fragment is called and committed, it only displays the first image and it is not swipable. Any thoughts how to achieve this?</p> <p>Here is the Fragment</p> <pre><code>import android.os.AsyncTask; import android.os.Bundle; import android.support.v4.app.Fragment; import android.support.v4.app.FragmentManager; import android.support.v4.app.FragmentStatePagerAdapter; import android.support.v4.app.FragmentTransaction; import android.support.v4.view.ViewPager; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; public class HowToFragment extends Fragment { private ViewPager mViewPager; private MyAdapter mAdapter; private int[] image_id = {R.drawable.image_1, R.drawable.image_2, R.drawable.image_3}; private static int image_pos = 0; public static Fragment newInstance(int pos){ image_pos = pos; return new HowToFragment(); } @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View v = inflater.inflate(R.layout.fragment_how_to_image, container, false); v.setBackgroundResource(image_id[image_pos]); return v; } @Override public void onActivityCreated(Bundle savedInstanceState) { super.onActivityCreated(savedInstanceState); mViewPager = new ViewPager(getActivity()); mViewPager.setId(R.id.viewPager_howto); FragmentManager fm = getFragmentManager(); mAdapter = new MyAdapter(fm); new setAdapterTask().execute(); } private class setAdapterTask extends AsyncTask&lt;Void,Void,Void&gt;{ protected Void doInBackground(Void... params) { return null; } @Override protected void onPostExecute(Void result) { mViewPager.setAdapter(mAdapter); } } private class MyAdapter extends FragmentStatePagerAdapter{ public MyAdapter(FragmentManager fm) { super(fm); // TODO Auto-generated constructor stub } @Override public int getCount() { return image_id.length; } @Override public Fragment getItem(int position) { return HowToFragment.newInstance(position); } @Override public void destroyItem(ViewGroup container, int position, Object object) { // TODO Auto-generated method stub FragmentManager manager = getFragmentManager(); FragmentTransaction ft = manager.beginTransaction(); ft.remove((Fragment) object); ft.commit(); super.destroyItem(container, position, object); } } } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
