EditTextPreference:

我来到这个解决方案，当然，只是如果你需要特定的edittextpreference，但你可以这样做，每一个偏好:

............

private static final String KEY_EDIT_TEXT_PREFERENCE2 = "on_a1";
public static  String value = "";

............

private void updatePreference(Preference preference, String key) {

            if (key.equals(KEY_EDIT_TEXT_PREFERENCE2)) {
                preference = findPreference(key);
                if (preference instanceof EditTextPreference) {
                    editTextPreference = (EditTextPreference) preference;
                    editTextPreference.setSummary(editTextPreference.getText());
                    value = editTextPreference.getText().toString();
                    return;
                }
                SharedPreferences sharedPrefs = getPreferenceManager().getSharedPreferences();
                preference.setSummary(sharedPrefs.getString(KEY_EDIT_TEXT_PREFERENCE2, ""));

            }
}

然后在onResume();

@Override
        public void onResume() {
            super.onResume();

            SharedPreferences etext = getPreferenceManager().getSharedPreferences();
            String str = etext.getString("value", "");
            editTextPreference = (EditTextPreference) findPreference(KEY_EDIT_TEXT_PREFERENCE2);
            editTextPreference.setText(str);
            editTextPreference.setSummary(editTextPreference.getText());

            getPreferenceScreen().getSharedPreferences()
                    .registerOnSharedPreferenceChangeListener(this);
        }

In:

@Override
        public void onSharedPreferenceChanged(SharedPreferences sharedPreferences, String key) {
            updatePreference(findPreference(key), key);
}

也许像ListPreference:修改getSummary来得到你想要的:

package your.package.preference;

import android.content.Context;
import android.util.AttributeSet;

public class EditTextPreference extends android.preference.EditTextPreference{
        public EditTextPreference(Context context, AttributeSet attrs, int defStyle) {
            super(context, attrs, defStyle);
        }

        public EditTextPreference(Context context, AttributeSet attrs) {
            super(context, attrs);
        }

        public EditTextPreference(Context context) {
            super(context);
        }

        @Override
        public CharSequence getSummary() {
            if(super.getSummary() == null) return null;

            String summary = super.getSummary().toString();
            return String.format(summary, getText());
        }
    }

在你的xml中使用这个:

<your.package.EditTextPreference
                android:key="pref_alpha"
                android:summary="Actual value: %s"
                android:title="Title"
                android:defaultValue="default"
                />

因此，您可以使用%s而不是实际值编写摘要。

只需将这一行添加到xml规范中。 应用:useSimpleSummaryProvider = " true "

例如:

< your.package.name.MyListPreference

android:key="noteInterval"
android:defaultValue="60"
android:title="Notification Interval"
android:entries="@array/noteInterval"
android:entryValues="@array/noteIntervalValues"
app:useSimpleSummaryProvider="true"

/>

如果你使用PreferenceFragment，这就是我解决它的方法。这是不言而喻的。

public static class SettingsFragment extends PreferenceFragment implements OnSharedPreferenceChangeListener {
    @Override
    public void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      addPreferencesFromResource(R.xml.settings);
      getPreferenceScreen().getSharedPreferences().registerOnSharedPreferenceChangeListener(this);
    }

    @Override
    public void onResume() {
      super.onResume();
      for (int i = 0; i < getPreferenceScreen().getPreferenceCount(); ++i) {
        Preference preference = getPreferenceScreen().getPreference(i);
        if (preference instanceof PreferenceGroup) {
          PreferenceGroup preferenceGroup = (PreferenceGroup) preference;
          for (int j = 0; j < preferenceGroup.getPreferenceCount(); ++j) {
            Preference singlePref = preferenceGroup.getPreference(j);
            updatePreference(singlePref, singlePref.getKey());
          }
        } else {
          updatePreference(preference, preference.getKey());
        }
      }
    }

    @Override
    public void onSharedPreferenceChanged(SharedPreferences sharedPreferences, String key) {
      updatePreference(findPreference(key), key);
    }

    private void updatePreference(Preference preference, String key) {
      if (preference == null) return;
      if (preference instanceof ListPreference) {
        ListPreference listPreference = (ListPreference) preference;
        listPreference.setSummary(listPreference.getEntry());
        return;
      }
      SharedPreferences sharedPrefs = getPreferenceManager().getSharedPreferences();
      preference.setSummary(sharedPrefs.getString(key, "Default"));
    }
  }

实际上，CheckBoxPreference确实能够根据复选框值指定不同的摘要。请参阅android:summaryOff和android:summaryOn属性(以及相应的CheckBoxPreference方法)。

public class ProfileManagement extends PreferenceActivity implements
OnPreferenceChangeListener {
    EditTextPreference screenName;
    ListPreference sex;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            addPreferencesFromResource(R.layout.profile_management);

            screenName = (EditTextPreference) findPreference("editTextPref");
            sex = (ListPreference) findPreference("sexSelector");

            screenName.setOnPreferenceChangeListener(this);
            sex.setOnPreferenceChangeListener(this);

    }   

    @Override
    public boolean onPreferenceChange(Preference preference, Object newValue) {
        preference.setSummary(newValue.toString());
        return true;
    }
}
