+/**
+ * A layout to be used with {@code PreferenceFragment} in v14 support library. This can be specified
+ * as the {@code android:layout} in the {@code app:preferenceFragmentStyle} in
+ * {@code app:preferenceTheme}.
+ *
+ * <p />Example:
+ * <pre>{@code
+ * &lt;style android:name="MyActivityTheme">
+ * &lt;item android:name="preferenceTheme">@style/MyPreferenceTheme&lt;/item>
+ * &lt;/style>
+ *
+ * &lt;style android:name="MyPreferenceTheme">

+ * &lt;style android:name="MyPreferenceFragmentStyle">
+ * &lt;item android:name="android:layout">@layout/my_preference_layout&lt;/item>
+ * &lt;/style>
+ * }</pre>
+ *
+ * where {@code my_preference_layout} is a layout that contains
+ * {@link com.android.setupwizardlib.GlifPreferenceLayout}.

+ * android:id="@id/list_container"

+ * android:layout_height="match_parent" />
+ * }</pre>
