Hide a preference in a PreferenceActivity

Question

Is possible to hide a preference in a PreferenceScreen? I don't need to disable it, it must be invisible (sometimes)

Important: I need to keep the min API level 7+

Answer 1

If your logout button (Preference) is in the PreferenceScreen, do this:

PreferenceScreen screen = getPreferenceScreen();
Preference logout = findPreference("logout");
if(screen != null && logout != null)
  screen.removePreference(logout);

Else if your logout button (Preference) is in a PreferenceCategory (which is inside a PreferenceScreen), do this:

PreferenceCategory category = (PreferenceCategory) findPreference("category_name");
Preference logout = findPrefence("logout");
if(category != null && logout != null)
  category.removePreference(logout);

You can put whatever your preferences name is, this is for example for a logout preference, if you have another Preference (eg CheckBoxPreference) you need to cast that specific Preference before findPreference.

Something like that should works:

Preference p = findPreference("your_preference_key");
getPreferenceScreen().removePreference(p);

If you use Support Library v7 Preference, you can use the setVisible method. It does exactly what you need.

You can now do this directly in xml with the AppCompat library.
