Body
I'm using a PreferenceActivity in my app. Defined the settings.xml as follows - <pre><code><?xml version="1.0" encoding="utf-8"?> <PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android" android:title="Preferences" > <PreferenceCategory android:title="Email Options" > <EditTextPreference android:dialogTitle="@string/pref_email_user_title" android:key="pref_email_user" android:summary="@string/pref_email_user_summary" android:persistent="true" android:title="@string/pref_email_user_title" /> <EditTextPreference android:dialogTitle="@string/pref_email_password_title" android:key="pref_email_password" android:summary="@string/pref_email_password_summary" android:persistent="true" android:title="@string/pref_email_password_title" /> </PreferenceCategory> </code></pre> Activity as follows - <pre><code>public class Prefs extends PreferenceActivity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); addPreferencesFromResource(R.xml.settings); } } </code></pre> Which is all you need, right? Apparently not though, because what happens is that I click on the 'email user' setting, it brings up a dialog which I use to type in a string value. However what I typed in isn't getting placed on the Settings screen, I still see the default value. I notice that the values are getting persisted in the preferences file under <code>/data/data/<package>/shared_prefs</code> I also don't see these persisted values when I relaunch the app - it shows default values. What's the bit of magic I'm missing?

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.
