Android: ListPreference hide/disable value

Question

I'm generating a listPreference dialog based on xml (entries and entryValues).

<string-array name="listArray">
    <item>Title (A-Z)</item>
    <item>Title (Z-A)</item>
    <item>Visits (default)</item>
    <item>Date</item>
    <item>Manual</item>
</string-array> 
<string-array name="listValues">
   <item>titleASC</item>
   <item>titleDESC</item>
   <item>visitsSort</item>
   <item>createSort</item>
   <item>manualSort</item>
</string-array>

I want to hide/disable some of the entries (for example: Manual) based on some other parameters.

I understand it should be inside this scope:

Preference sorted = (Preference) findPreference(OPT_SORT);

        sorted.setOnPreferenceClickListener(new OnPreferenceClickListener() {
            public boolean onPreferenceClick(Preference preference) {

                if (params) {
                    What should i put here to hide/disable some of the entries?
                }

                return true;
            }
        });

Thank you!

EDIT:

Best solution I found is to load a different set of Entries and EntryValues. On Preference class (onCreate):

ListPreference sortBy = (ListPreference) findPreference(OPT_SORT);
        if (isTabletDevice()) {
            sortBy.setEntries(getResources().getStringArray(R.array.HClistArray));
            sortBy.setEntryValues(getResources().getStringArray(R.array.HClistValues));
        }

Hope this helps anyone! :)

Answer 1

AFAIK, ListPreference does not support this. You might be able to create your own subclass of ListPreference where you use a custom Adapter and indicate which items are and are not enabled.

Answer 2

It's quite late answer, I hope that's will help.

    private static Preference.OnPreferenceChangeListener sBindPreferenceSummaryToValueListener = new Preference.OnPreferenceChangeListener() {
    @Override
    public boolean onPreferenceChange(Preference preference, Object value) {
        String stringValue = value.toString();

        if (preference instanceof ListPreference) {
            // For list preferences, look up the correct display value in
            // the preference's 'entries' list.
            ListPreference listPreference = (ListPreference) preference;
            int index = listPreference.findIndexOfValue(stringValue);

            // Set the summary to reflect the new value.
            preference
                    .setSummary(index >= 0 ? listPreference.getEntries()[index]
                            : null);


            // If it's sync_factory_list, enable/disable appropriate settings
            if(preference.getKey().equalsIgnoreCase("sync_factory_list")){

                Preference p_api_key = preference.getPreferenceManager().findPreference("ws_api_key");
                Preference p_api_url = preference.getPreferenceManager().findPreference("ws_api_url");

                switch ( index) {
                    case 0: //local
                        p_api_key.setEnabled(false);
                        p_api_url.setEnabled(false);
                        break;
                    case 1: //prestashop webservice
                        p_api_key.setEnabled(true);
                        p_api_url.setEnabled(true);
                        break;
                    case 2: //thrift
                        p_api_key.setEnabled(false);
                        p_api_url.setEnabled(false);

                        break;

                    default:
                        p_api_key.setEnabled(false);
                        p_api_url.setEnabled(false);
                        break;
                }

            }



        }
    ...
    return true;
}

}
