How to show and hide preferences on Android dynamically?

Question

Is there a way to dynamically show and hide preferences? In my case, I have a checkbox preference that would disable or enable one of 2 preference groups (\"with-\" and \"w

I needed something similar: toggling a switch to hide or show two extra preferences. Check out the sample app from Android-Support-Preference-V7-Fix which bring some new preference types and fixes some issues from the official library. There's an example there to toggle a checkbox to show or hide a preference category.

In the fragment that extends PreferenceFragmentCompatDividers, you could use something like:

findPreference("pref_show_extra_stuff").setOnPreferenceChangeListener(new Preference.OnPreferenceChangeListener() {
        @Override
        public boolean onPreferenceChange(Preference preference, Object newValue) {
            findPreference("pref_extra_stuff_01").setVisible((Boolean) newValue);
            findPreference("pref_extra_stuff_02").setVisible((Boolean) newValue);
            return true;
        }
    });

pref_extra_stuff_01 and pref_extra_stuff_02 are the two preferences that are hidden when pref_show_extra_stuff is toggled.
