【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
