try this:

    @Override
    public boolean onPreferenceTreeClick(PreferenceScreen preferenceScreen, @NonNull Preference preference) {
        CheckBoxPreference cb1 = null;
        CheckBoxPreference cb2 = null;
        ListAdapter adapter = preferenceScreen.getRootAdapter();
        for(int i = 0; i < preferenceScreen.getRootAdapter().getCount(); i++)
        {
            //attention to type and key
            Preference pref = (Preference) adapter.getItem(i);
            if (pref == null || pref.getKey() == null)
                continue;
            if (pref.getKey().equals(getString(R.string.tag_preference_key_always_zoom_to_akt_position)))
                cb1 = (CheckBoxPreference) pref;
            if (pref.getKey().equals(getString(R.string.tag_preference_key_always_zoom_to_last_location)))
                cb2 = (CheckBoxPreference) pref;
            if (cb1 != null && cb2 != null)
                break;
        }
        //be safe
        if (cb1 == null || cb2 == null)
            return super.onPreferenceTreeClick(preferenceScreen, preference);

        if (preference.getKey().equals(getString(R.string.tag_preference_key_always_zoom_to_akt_position))) {
            CheckBoxPreference cb = (CheckBoxPreference) preference;
            cb2.setChecked(!cb.isChecked());
        }
        if (preference.getKey().equals(getString(R.string.tag_preference_key_always_zoom_to_last_location))) {
            CheckBoxPreference cb = (CheckBoxPreference) preference;
            cb1.setChecked(!cb.isChecked());
        }
        return super.onPreferenceTreeClick(preferenceScreen, preference);
    }
