Body
I had the same problem and solve it thanks to Xuelong and getDialog() but without needing to manage onPreferenceTreeClick(). <ol> <li>You need to keep an instance (myPreferenceScreen) of the PreferenceScreen you want to return from</li> <li>You have to give him a key in XML</li> <li>Retrieve the instance with findPreference("MyPreferenceScreenKey");</li> <li>Once you have to return , use this method : myPreferenceScreen.getDialog().dismiss()</li> </ol> You will then return from where you came from. Here is a epurated example : Xml file : <pre><code><?xml version="1.0" encoding="utf-8"?> <PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android"> <ListPreference android:key="contactList"/> <PreferenceScreen android:title="My Sub Preference Screen ..." android:key="mySubScreenKey"> <EditTextPreference android:key="foo1"/> </PreferenceScreen> </PreferenceScreen> </code></pre> Java file : <pre><code>public class ParanoidPreferenceManager extends PreferenceActivity { ListPreference contactList; EditTextPreference foo1; PreferenceScreen mySubScreenKey; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); //Load XML preference file addPreferencesFromResource(R.xml.preferences); contactList = (ListPreference) findPreference("contactList"); foo1= (EditTextPreference) findPreference("foo1"); screenContact = (PreferenceScreen) findPreference("screenAddContact"); foo1.setOnPreferenceChangeListener(new OnPreferenceChangeListener() { @Override public boolean onPreferenceChange(Preference preference, Object newValue) { mySubScreenKey.getDialog().dismiss(); return false; } }); } } </code></pre> That's it Sorry for presentation, this is my first post on this site. Bye dudes

1. COYeah! Good job. Thanks to share. this is a good way in a preferenceActivity which has a little preference item and less level. In my application, I've managed a large PreferenceActivity and it has many return Preference, then write code in onPreferenceTreeClick() is a good way to make every return item work without write different Listener for every Preferences. Ha and this Question is the first one i post here too. lol~~

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.
