    <p>I've met the problem that trouble me for days.</p> <p>There is a <code>ViewPager</code> in the main activity which holds 3 <code>Fragment</code>s as tab fragments. In the <strong>first</strong> fragment there is a <code>ListView</code> which holds some views, and which is the most important, another <code>ViewPager</code>. I want to hold some photos in the sub <code>ViewPager</code>, and use some more fragments here.</p> <p>Now there is the trouble:<br> When the <strong>first</strong> <code>Fragment</code> is stopped (The <strong>third</strong> fragment in the parent <code>ViewPager</code> is seen on screen) and resumed (the user switch to the <strong>second</strong> fragment), the app crashes and the debugger says:</p> <pre><code>java.lang.IllegalArgumentException: No view found for id 0x7f05008b (com.example.viewpager:id/sub_viewpager) for fragment ScreenSlidePageFragment </code></pre> <p>I've already use the <code>getChildFragmentManager()</code> as this is a situation of <a href="http://developer.android.com/about/versions/android-4.2.html#NestedFragments" rel="noreferrer">nested fragments</a>.</p> <p>Here is the key code of list adapter corresponding to the first fragment in the parent ViewPager:</p> <pre><code>@Override public View getView(int position, View convertView, ViewGroup parent) { int type = getItemViewType(position); switch (type) { case TYPE_BANNER: if (convertView == null) { convertView = mBannerView.getBannerView(parent); } mBannerView.update(convertView); break; case TYPE_ITEM: break; } return convertView; } </code></pre> <p>Here is the code of <code>mBannerView</code>:</p> <pre><code>public class BannerView { private static final DisplayImageOptions IMAGE_OPTIONS_SCALE_STRETCHED = new DisplayImageOptions.Builder() .cacheInMemory() .cacheOnDisc() .imageScaleType(ImageScaleType.EXACTLY_STRETCHED) .build(); private FragmentActivity mActivity; private Fragment mFragment; private List&lt;Banner&gt; mBanners; private ScreenSlidePagerAdapter mPagerAdapter; private ViewPager mViewPager; public BannerView(FragmentActivity activity, Fragment fragment) { mActivity = activity; mFragment = fragment; } public void update(View convertView) { mViewPager = (ViewPager) convertView; if (mBanners != null &amp;&amp; !mBanners.isEmpty()) { if (mPagerAdapter == null) { mPagerAdapter = new ScreenSlidePagerAdapter(mFragment.getChildFragmentManager()); mViewPager.setAdapter(mPagerAdapter); } } mViewPager.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { if (mOnBannerClickListener != null) { mOnBannerClickListener.onBannerClick(); } } }); } class ScreenSlidePagerAdapter extends FragmentStatePagerAdapter { public ScreenSlidePagerAdapter(FragmentManager fm) { super(fm); } @Override public Fragment getItem(int position) { return new ScreenSlidePageFragment(mBanners.get(position).getImageUrl()); } @Override public int getCount() { return mBanners == null ? 0 : mBanners.size(); } } class ScreenSlidePageFragment extends Fragment { private String mUrl; ScreenSlidePageFragment(String url) { super(); mUrl = url; } @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View view = inflater.inflate(R.layout.item_banner, container, false); if (view != null) { ImageView imageView = (ImageView) view.findViewById(R.id.item_banner_image); imageView.setLayoutParams(new LinearLayout.LayoutParams( LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.MATCH_PARENT)); ImageLoader.getInstance().displayImage(mUrl, imageView, IMAGE_OPTIONS_SCALE_STRETCHED); } return view; } } } </code></pre> <p>Here is the detailed error list:</p> <pre><code>11-10 18:12:19.217 1444-1444/?

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.

SQuiL has stopped working due to an internal error.

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