事情是這樣的：

((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)); 
    } 
});
