How to block a ListPreference dialog from opening when that ListPreference was clicked on?

Question

I've got a ListPreference in which I can select items and set parameters for purposes. When I click on it in my Settings Fragment where all of my Preferences are, it opens a dialog and lets me choose the items listed in it. I am using two handlers, OnPreferenceClickListener (Called when I click on my ListPreference) and OnPreferenceChangeListener (Called when I select an item in it).

I want to block the dialog from opening without disabling the ListPreference at all so that I cannot select the items in it. I've blocked changing the items with a global boolean in my OnPreferenceChangeListener.

boolean canChange = true;

final ListPreference listPreference = (ListPreference) findPreference("myListPreference");

listPreference.setOnPreferenceClickListener(new Preference.OnPreferenceClickListener() {

    @Override
    public boolean onPreferenceClick(Preference preference) {

        canChange = myCondition;
        return true;
    }
});

listPreference.setOnPreferenceChangeListener(new Preference.OnPreferenceChangeListener() {

    @Override
    public boolean onPreferenceChange(Preference preference, Object newValue) {

        if(canChange)
            someValueHolder = listPreference.findIndexOfValue(newValue.toString());

        return true;
    }
});

This is a bad code but the best attempt I could think of to avoid changing the listed items if myCondition is false. But I want to know how I can block the Dialog from popping up when I click on the preference if myCondition is false and instead open up a dialog with a warning message like You cannot change this ListPreference when myCondition is false!?
