After 20 min of hair pulling I found an elegant solution to this problem. First, extend the preference, then override the getView(View convertView, ViewGroup parent) method. My case was this: I had a preference layout with app icon and 2 text views(app name and version). I want to change app version programatically. How do I do this? just take a look below: <pre><code>public class AboutUsPreference extends Preference { public AboutUsPreference(Context context) { super(context); } public AboutUsPreference(Context context, AttributeSet attrs) { super(context, attrs); } public AboutUsPreference(Context context, AttributeSet attrs, int defStyle) { super(context, attrs, defStyle); } @Override public View getView(View convertView, ViewGroup parent) { View v = super.getView(convertView, parent); ((TextView)v.findViewById(R.id.textView2)).setText(getAppVersion()); return v; } private String getAppVersion(){ PackageInfo pInfo = null; try { pInfo = getContext().getPackageManager().getPackageInfo(getContext().getPackageName(), 0); } catch (NameNotFoundException e) { Log.e(getClass().getName(), e.getMessage(), e); return ""; } String version = pInfo.versionName; return getContext().getString(R.string.version, version); } } </code></pre> The solution is this: <code>View v = super.getView(convertView, parent);</code> when overriding getView method. super.getview call will return your layout view. And my xml preference looks like: <pre><code><com.audioRec.android.settings.aboutUs.AboutUsPreference android:layout="@layout/about_preference_layout"/> </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.
