    <p>I have a ListPreference and I want to show the current entry in the summary. According to the <a href="http://developer.android.com/reference/android/preference/ListPreference.html#getSummary%28%29" rel="nofollow">docs for ListPreference.getSummary()</a>, I'm supposed to be able to do this by including <code>%s</code> in the summary string. Unfortunately, the activity just displays the <code>%s</code> in the summary.</p> <p>The XML is pretty standard:</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android"&gt; &lt;ListPreference android:key="displayMode" android:summary="@string/display_mode_summary" android:title="@string/display_mode" android:defaultValue="BOTH" android:entries="@array/displayModes" android:entryValues="@array/displayModeValues" /&gt; &lt;/PreferenceScreen&gt; </code></pre> <p>The value of the string <code>display_mode_summary</code> is just <code>%s</code>. (The value <code>"BOTH"</code> is present in the <code>displayModeValues</code> array.) If I subclass ListPreference like this:</p> <pre><code>public final class DisplayModePreference extends ListPreference { // ... @Override public CharSequence getSummary() { return String.format(super.getSummary().toString(), getEntry()); } } </code></pre> <p>then when the preferences activity starts, the current value is correctly interpolated into the summary. But when I click on the preference and select a different value from the dialog, when the dialog closes the summary still shows the now-old value. I need to close the preferences activity and restart it to see the change.</p> <p>I've tried this in several emulators at different API levels. What do I need to so that the displayed summary always reflects the current value?</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.
