Body
I found a slightly less gross way to get a handle on a <code>Fragment</code> created by a <code>FragmentPagerAdapter</code>. Instead of imitating the way tags are created, override <code>instantiateItem()</code>, get the <code>Fragment</code> returned by the superclass, and save the tag in <code>TabInfo</code>. This works for me on API >= 15, may work with lower. This still makes some assumptions about private code. <pre><code>static final class TabInfo { private final Class<?> clss; private final Bundle args; private String tag; // ** add this TabInfo(Class<?> _class, Bundle _args) { clss = _class; args = _args; } } @Override public Object instantiateItem(ViewGroup container, int position) { final Fragment fragment = (Fragment) super.instantiateItem(container, position); final TabInfo info = mTabs.get(position); info.tag = fragment.getTag(); // set it here return fragment; } </code></pre> Or in API < 16, I think <code>instantiateItem()</code> takes a <code>View()</code> instead of <code>ViewGroup()</code>, like this: <pre><code>public Object instantiateItem(View container, int position); </code></pre> Then allow a way to get the <code>Fragment</code>, keeping the hack contained. <pre><code>public Fragment getFragment(int index) { return mContext.getFragmentManager().findFragmentByTag(mTabs.get(index).tag); } </code></pre> For that to work, the declaration for <code>mContext</code> needs to change to <code>Activity</code>, it's passed in as an <code>Activity</code> anyway: <pre><code>private final Activity mContext; </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.
