可以在Android中动态更改EditTextPreference的摘要吗？

    android:key="edit_text_preference"
    android:title="EditText Preference"
    android:summary="This is the summary"
    android:defaultValue="Default value" />

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    getSupportFragmentManager()
            .beginTransaction()
            .replace(android.R.id.content, new SettingsFragment())
            .commit();

    EditTextPreference editTextPreference = findPreference("edit_text_preference");
    editTextPreference.setOnPreferenceChangeListener(new Preference.OnPreferenceChangeListener() {
        @Override
        public boolean onPreferenceChange(Preference preference, Object newValue) {
            preference.setSummary(newValue.toString());
            return true;
        }
    });
}
