Answer 1

Something like this:

((SeekBarPreference) findPreference(R.id.preference_delay_seek_bar)).setOnPreferenceChangeListener(new OnPreferenceChangeListener() {
  @Override
  public boolean onPreferenceChange(Preference preference, Object newValue) {
    final int progress = Integer.valueOf(String.valueOf(newValue));
    preference.setSummary(String.format("My progress value: %d", progress));
  }
});
