【安卓笔记】高速的发展设置界面—–PreferenceActivity

通常app都会有一个设置界面，例如以下：

package com.example.preferenceactivitydemo1;
import android.os.Bundle;
import android.preference.PreferenceActivity;
public class MainActivity extends PreferenceActivity
{
	@SuppressWarnings("deprecation")
	@Override
	protected void onCreate(Bundle savedInstanceState)
	{
		super.onCreate(savedInstanceState);
		addPreferencesFromResource(R.xml.main_preference);
	}
	
}

<?xml version="1.0" encoding="utf-8"?
><PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android"    android:title="标题" >    <PreferenceCategory        android:summary="分组1"        android:title="分组1标题" >        <ListPreference            android:defaultValue="@string/defaultvalues"            android:dialogTitle="对话框标题"            android:entries="@array/entries"            android:entryValues="@array/entriesvalue"            android:key="myListPreference"            android:summary="标题说明"            android:title="小标题" />        <CheckBoxPreference            android:key="doubi"            android:summaryOff="逗比模式关闭"            android:summaryOn="逗比模式开启"            android:title="逗比模式" >        </CheckBoxPreference>    </PreferenceCategory>    <PreferenceCategory        android:summary="分组2"        android:title="分组2标题" >        <SwitchPreference            android:key="fly"            android:summaryOff="已关闭飞行模式"            android:summaryOn="已开启飞行模式"            android:switchTextOff="关闭"            android:switchTextOn="开启"            android:title="飞行模式" >        </SwitchPreference>        <EditTextPreference            android:defaultValue="zhangsan"            android:dialogTitle="编辑姓名"            android:key="name"            android:summary="编辑您的姓名"            android:title="编辑" >        </EditTextPreference>    </PreferenceCategory></PreferenceScreen>

当中引用了string.xml的相关内容：

<?xml version="1.0" encoding="utf-8"?
><resources>    <string name="app_name">PreferenceActivityDemo1</string>    <string name="action_settings">Settings</string>    <string name="hello_world">Hello world!</string>	<string-array name="entries">	    <item>小苹果</item>	    <item>小香蕉</item>	    <item>小西瓜</item>	</string-array>	<string-array name="entriesvalue">	    <item>apple</item>	    <item>banana</item>	    <item>watermelon</item>	</string-array>	<string name="defaultvalues">apple</string></resources>
