一、Java代码

需要建立两个类，其MyFragment需要继承PreferenceFragment

1、MyFragment

package com.hxzy.preferenceactivity;import android.content.SharedPreferences;
import android.content.SharedPreferences.OnSharedPreferenceChangeListener;
import android.os.Bundle;
import android.preference.EditTextPreference;
import android.preference.ListPreference;
import android.preference.Preference;
import android.preference.PreferenceFragment;
import android.preference.PreferenceManager;
import android.preference.PreferenceScreen;
import android.util.Log;
import android.widget.Toast;public class MyFragment extends PreferenceFragment{private MyOnSharePreferenceChangeListener mOnSharePreferenceChangeListener = new MyOnSharePreferenceChangeListener();private final String A_KEY = "edittext_key_1";private final String LIST_KEY = "list_key_1";private EditTextPreference mEditTextPreference;private ListPreference mListPreference;@Overridepublic void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);this.addPreferencesFromResource(R.xml.preferences);// 通用的读取设置的某个值的方法SharedPreferences mSharePreferences = PreferenceManager.getDefaultSharedPreferences(getActivity());String s = mSharePreferences.getString("edittext_key_1", "暂时为空");Boolean b = mSharePreferences.getBoolean("checkbox_key_1", true);Log.d("edittext_key_1", s);Log.d("checkbox_key_1", b + "");mSharePreferences.registerOnSharedPreferenceChangeListener(mOnSharePreferenceChangeListener);// 预读取。为PreferenceActivity中的某个设置选项初始化值// 类似于以前所用的EditText mEditText=findViewById(R.id.editText)，key类似于id；mEditTextPreference = (EditTextPreference) findPreference(A_KEY);mEditTextPreference.setSummary(s);mListPreference = (ListPreference) findPreference(LIST_KEY);}@Overridepublic void onPause() {super.onPause();getPreferenceScreen().getSharedPreferences().unregisterOnSharedPreferenceChangeListener(mOnSharePreferenceChangeListener);}@Overridepublic void onResume() {super.onResume();getPreferenceScreen().getSharedPreferences().registerOnSharedPreferenceChangeListener(mOnSharePreferenceChangeListener);}// 那一个设置选项栏被触发@Overridepublic boolean onPreferenceTreeClick(PreferenceScreen preferenceScreen, Preference preference) {Toast.makeText(getActivity(), preference.getSummary(), Toast.LENGTH_LONG).show();return false;}private class MyOnSharePreferenceChangeListener implements OnSharedPreferenceChangeListener {@Overridepublic void onSharedPreferenceChanged(SharedPreferences sharedPreferences, String key) {Toast.makeText(getActivity(), key, 0).show();if (key.equals(A_KEY)){String s = sharedPreferences.getString(A_KEY, "null");mEditTextPreference.setSummary(s);}if (key.equals(LIST_KEY)) {String e = mListPreference.getEntry() + "";String v = mListPreference.getValue() + "";mListPreference.setSummary(e + ":" + v);}}}
}

2、MainActivity

package com.hxzy.preferenceactivity;import android.app.Activity;
import android.os.Bundle;public class MainActivity extends Activity {@Overridepublic void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);this.getFragmentManager().beginTransaction().replace(android.R.id.content, new MyFragment()).commit();}
}

二、res/xml目录下的preferences.xml

<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android" ><PreferenceCategory android:title="[first group])" ><EditTextPreferenceandroid:defaultValue="111111"android:key="edittext_key_1"android:summary="editview summary"android:title="edittext title" /><ListPreferenceandroid:dialogIcon="@drawable/a"android:dialogTitle="list dialog title"android:entries="@array/citys"android:entryValues="@array/citys_code"android:icon="@drawable/ic_launcher"android:key="list_key_1"android:summary="list summary"android:title="list title" /><!-- defaultValue的true表示初始化时打勾，false不打勾 --><CheckBoxPreferenceandroid:defaultValue="false"android:key="checkbox_key_1"android:summary="checkbox summary"android:title="checkbox title" /></PreferenceCategory><Preferenceandroid:summary="preference summary"android:title="preference title" /><PreferenceCategoryandroid:defaultValue="aaaaaa"android:key="secondgroup_key"android:summary="secondgroup summary"android:title="[second group]" ><CheckBoxPreferenceandroid:defaultValue="true"android:key="checkbox_key_2"android:summary="checkbox summary"android:title="checkbox title" /><EditTextPreferenceandroid:defaultValue="bbbbbbbbb"android:key="edittext_key_2"android:summary="edittext summary"android:title="edittext title" /></PreferenceCategory><Preferenceandroid:summary="http://blog.csdn.net/zhangphil"android:title="浏览网页" ><intentandroid:action="android.intent.action.VIEW"android:data="http://blog.csdn.net/zhangphil" /></Preference><!-- 此处将跳转到下一屏设置 --><PreferenceScreenandroid:key="preference_screen_key_2"android:persistent="true"android:title="preference screen 2" ><EditTextPreferenceandroid:defaultValue="cccccc"android:key="edittext_key_3"android:summary="second summary"android:title="second title" /></PreferenceScreen><PreferenceScreenandroid:key="preference_screen_key_3"android:persistent="true"android:title="preference screen 3" ><EditTextPreferenceandroid:defaultValue="ccccccd"android:key="edittext_key_4"android:summary="second summary"android:title="second title" /></PreferenceScreen><SwitchPreferenceandroid:defaultValue="fffff"android:key="SwitchPreference_key"android:summary="SwitchPreference summary"android:title="SwitchPreference title" /></PreferenceScreen>

三、需要的res/values/arrays.xml

<?xml version="1.0" encoding="utf-8"?>
<resources><string-array name="citys"><item>成都</item><item>北京</item><item>上海</item></string-array><string-array name="citys_code"><item>028</item><item>010</item><item>021</item></string-array>
</resources>
