Androidx: Cannot resolve method 'getDialog' in 'ListPreference'

I have used a custom ListPreference which worked well before. Then upgrading to Androidx, it appears this error:

import androidx.preference.ListPreference;
....
public static class myPreferenceFragment extends PreferenceFragmentCompat implements SharedPreferences.OnSharedPreferenceChangeListener {
...
ListPreference coustomListPreference = (ListPreference) findPreference("list_XXXX");
coustomListPreference.setOnPreferenceClickListener(new Preference.OnPreferenceClickListener() {
   public boolean onPreferenceClick(Preference preference) {
      ... 
      if(!XXXXPermissionGranted(): when users don't grant some Permission, causing this ListPreference to have nothing to show) 
       coustomListPreference.getDialog().dismiss();
   }

> Cannot resolve method 'getDialog' in 'ListPreference'

I've searched this topic and I cannot find a straight answer.

For Androidx, it needs to do these things in addition to your PreferenceFragmentCompat to accomplish the coustomListPreference.getDialog().dismiss() in the question statements.

This could be a template if you want to make the dialog dismiss or to customize the Entries/Values of the ListPreference.

public static class myDialogPrefFragCompat extends PreferenceDialogFragmentCompat {
        public static myDialogPrefFragCompat newInstance(String key) {
            final myDialogPrefFragCompat fragment = new myDialogPrefFragCompat();
            final Bundle bundle = new Bundle(1);
            bundle.putString(ARG_KEY, key);
            fragment.setArguments(bundle);
            return fragment;
        }
        @Override
        public void onDialogClosed(boolean positiveResult) {
            if (positiveResult) {
                // do things
            }
        }
}

public static class myPreferenceFragment extends PreferenceFragmentCompat implements SharedPreferences.OnSharedPreferenceChangeListener {
    ...
private static final String DIALOG_FRAGMENT_TAG = "myDialogPreference";
        @Override
        public void onDisplayPreferenceDialog(Preference preference) {
            if (getParentFragmentManager().findFragmentByTag(DIALOG_FRAGMENT_TAG) != null) {
                return;
            }

            if (preference instanceof ListPreference) {
                if (preference.getKey().equals("list_XXXX")){

                    initXXXXPermissionToGo(); //Request Android Permission such like Contacts etc. for customizing the Entries/Values of the ListPreference
                    if(XXXXPermissionGranted())
                        super.onDisplayPreferenceDialog(preference);
                    /*else
                        super.onDisplayPreferenceDialog(preference); 
when the Permission not granted, nothing can be set in ListPreference Entries/Values, and there's no need to see it. This equals 
coustomListPreference.getDialog().dismiss() in the question*/
                }else
                    super.onDisplayPreferenceDialog(preference);
            } else {
                super.onDisplayPreferenceDialog(preference);
            }
        }
