安卓系統設置選項的框架。，安卓系統設置框架

首先在res文件中創建一個xml文件夾，創建preference.xml文件，然後寫布局：

 1 <?xml version="1.0" encoding="utf-8"?>
 2 <PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android" >
 3 
 4     <PreferenceCategory android:title="系統信息" >
 5         <EditTextPreference
 6             android:defaultValue="機主姓名"
 7             android:icon="@drawable/ic_launcher"
 8             android:key="edit_text_key_1"
 9             android:summary="木子小新"
10             android:title="機主姓名" />
11 
12         <ListPreference
13             android:dialogIcon="@drawable/ic_launcher"
14             android:dialogTitle="城市區號"
15             android:entries="@array/city"
16             android:entryValues="@array/city_quhao"
17             android:icon="@drawable/ic_launcher"
18             android:key="listpreference"
19             android:title="區號" />
20     </PreferenceCategory>
21     <PreferenceCategory android:title="系統設置" >
22         <Preference
23             android:icon="@drawable/bokeyuan"
24             android:summary="http://www.cnblogs.com/labixiaoxin/"
25             android:title="機主博客" >
26             <intent
27                 android:action="android.intent.action.VIEW"
28                 android:data="http://www.cnblogs.com/labixiaoxin/" />
29         </Preference>
30 
31         <SwitchPreference
32             android:icon="@drawable/wifi"
33             android:key="wifi"
34             android:title="wifi開關" />
35         <SwitchPreference
36             android:icon="@drawable/lanya"
37             android:key="lanya"
38             android:title="藍牙開關" />
39 
40         <CheckBoxPreference
41             android:defaultValue="true"
42             android:icon="@drawable/xuanzhuahn"
43             android:key="checkbox_key_xuanzhuan"
44             android:title="旋轉" />
45 
46         <RingtonePreference
47             android:icon="@drawable/ring"
48             android:key="ring"
49             android:title="鈴聲" />
50     </PreferenceCategory>
51 
52     <PreferenceScreen
53         android:icon="@drawable/ic_launcher"
54         android:key="preference_screen_2_key"
55         android:persistent="false"
56         android:title="其他設置" >
57         <CheckBoxPreference
58             android:defaultValue="true"
59             android:icon="@drawable/ic_launcher"
60             android:key="checkbox_key_wangluo"
61             android:summary="網絡已經開啟"
62             android:title="網絡" />
63     </PreferenceScreen>
64 
65 </PreferenceScreen>

從主Acitivity中加載SettingFragment：

 1 package com.lixu.android_set;
 2 
 3 import android.app.Activity;
 4 import android.app.FragmentManager;
 5 import android.app.FragmentTransaction;
 6 import android.os.Bundle;
 7 
 8 public class MainActivity extends Activity {
 9 
10     @Override
11     protected void onCreate(Bundle savedInstanceState) {
12         super.onCreate(savedInstanceState);
13         // 創建Fragment管理器
14         FragmentManager fm = this.getFragmentManager();
15         FragmentTransaction ft = fm.beginTransaction();
16         // 將原有的Activity替換成Fragment。也可以添加到原有之上不覆蓋 如：ft.add(R.id.rel, new
17         // Fragment()) ;如果添加的多了會比較耗資源。
18         ft.replace(android.R.id.content, new SettingFragment());
19         // 提交
20         ft.commit();
21 
22     }
23 }

  1 package com.lixu.android_set;
  2 
  3 import android.content.SharedPreferences;
  4 import android.content.SharedPreferences.OnSharedPreferenceChangeListener;
  5 import android.os.Bundle;
  6 import android.preference.CheckBoxPreference;
  7 import android.preference.EditTextPreference;
  8 import android.preference.ListPreference;
  9 import android.preference.PreferenceFragment;
 10 import android.preference.PreferenceManager;
 11 import android.preference.SwitchPreference;
 12 
 13 //安卓官方申明在3.0版本後最好不要用FragmentActivity 應該用PreferenceFragment，在從主Activity中調用。
 14 public class SettingFragment extends PreferenceFragment {
 15 
 16     private MyListener mMyListener = new MyListener();
