    <p>I'm having some difficulties getting a PreferenceFragment to load using XML. It keeps throwing a <strong>ClassCastException</strong> "PreferenceFragmentClass cannot be cast to android.support.v4.app.Fragment". The code is intended to run on API14 and higher.</p> <p>Here's my code:</p> <pre><code>import android.os.Bundle; import android.preference.PreferenceFragment; public class SettingsFragment extends PreferenceFragment { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); addPreferencesFromResource(R.xml.settings); } } </code></pre> <p>Here's the code where SettingsFragment is being used in:</p> <pre><code>import android.app.ActionBar; import android.os.Bundle; import android.support.v4.app.FragmentActivity; import android.support.v4.view.ViewPager; public class FragmentsSetup extends FragmentActivity { private ViewPager viewPager; private TabsAdapter tabsAdapter; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); viewPager = new ViewPager(this); viewPager.setId(R.id.pager); setContentView(viewPager); final ActionBar actionBar = getActionBar(); actionBar.setDisplayShowTitleEnabled(false); actionBar.setDisplayShowHomeEnabled(false); actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS); tabsAdapter = new TabsAdapter(this, viewPager); tabsAdapter.addTab(actionBar.newTab().setText(getString(R.string.forwarding_tab).toUpperCase()), ForwardingFragment.class, null); tabsAdapter.addTab(actionBar.newTab().setText(getString(R.string.settings_tab).toUpperCase()), SettingsFragment.class, null); } } </code></pre> <p>Any tips would be greatly appreciated.</p>

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.
