    <p>I have a preference.xml file, and I want to show or hide some of the entry of this file. But the problem is that the preferences aren't hidden. My code is the following:</p> <pre><code> @Override public void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); addPreferencesFromResource(R.xml.preferences); Preference customPref = (Preference) findPreference(getText(R.string.about)); customPref.setOnPreferenceClickListener(this); Preference termAndConditions = (Preference) findPreference(getText(R.string.term_and_conditions)); termAndConditions.setOnPreferenceClickListener(this); Preference privacyStatement = (Preference) findPreference(getText(R.string.privacy_statement)); privacyStatement.setOnPreferenceClickListener(this); Preference login_with_facebook = (Preference) findPreference(getText(R.string.login_with_facebook)); login_with_facebook.setOnPreferenceClickListener(this); Preference register_new_account = (Preference) findPreference(getText(R.string.register_new_account)); register_new_account.setOnPreferenceClickListener(this); Preference login = (Preference) findPreference(getText(R.string.login)); login.setOnPreferenceClickListener(this); Preference my = (Preference) findPreference(getText(R.string.my)); my.setOnPreferenceClickListener(this); Preference miles_and_more = (Preference) findPreference(getText(R.string.miles_and_more)); miles_and_more.setOnPreferenceClickListener(this); Preference voucher_booking = (Preference) findPreference(getText(R.string.voucher_booking)); voucher_booking.setOnPreferenceClickListener(this); Preference invite_friends = (Preference) findPreference(getText(R.string.invite_friends)); invite_friends.setOnPreferenceClickListener(this); } onResume{ buildLogin() } private void buildLogin() { PreferenceScreen preferenceScreen = getPreferenceScreen(); hidePreferences(preferenceScreen, R.string.my); hidePreferences(preferenceScreen, R.string.miles_and_more); hidePreferences(preferenceScreen, R.string.voucher_booking); hidePreferences(preferenceScreen, R.string.invite_friends); } private void hidePreferences(PreferenceScreen preferenceScreen, int preferenceKey) { Preference customPref = (Preference) findPreference(getText(preferenceKey)); preferenceScreen.removePreference(customPref); } </code></pre> <p>the idea is to hide some of the preferences on onResume(). This class is extending from PreferenceFragment. Can some one please point what am I doing wrong. None of the preferences are hidden.</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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
