写应用程序时，一般把一些配置写在xml文件里，方便配置！然后在应用启动的时（在继承的application里）初始化配置

//在application里做的初始化工作	
// 初始化设置
SettingUtility.setSettingUtility();

使用xml里的配置

<span style="white-space:pre">	</span>Logger.DEBUG = SettingUtility.getBooleanSetting("debug");

	/**
	 * 程序的文件目录，如果setting配置的是android，标志目录位于/sdcard/Application/PackageName/...下<br/>
	 * 否则，就是/sdcard/setting[root_path]/...目录
	 * 
	 * @return
	 */
	public String getAppPath() {
		if ("android".equals(SettingUtility.getStringSetting("root_path")))
			return getExternalCacheDir().getAbsolutePath() + File.separator;
		
		return SdcardUtils.getSdcardPath() + File.separator + SettingUtility.getStringSetting("root_path") + File.separator;
	}

初始化工具类

public class SettingUtility {

	private static Map<String,Setting> settingMap;

	static {
		settingMap = new HashMap<String,Setting>();
	}

	private SettingUtility() {

	}

	public static void setSettingUtility() {
		
		addSettings("settings");
<span style="white-space:pre">	</span>/**
<span style="white-space:pre">	</span>*主要是一些初始化代码
        if (SdcardUtils.hasSdcardAndCanWrite()) {
            File rootFile = new File(GlobalContext.getInstance().getAppPath());
            if (!rootFile.exists())
                rootFile.mkdirs();

            // 数据缓存目录设置
            File jsonFile = new File(rootFile.getAbsolutePath() + File.separator + getPermanentSettingAsStr("com_m_common_json","files"));
            if (!jsonFile.exists())
                jsonFile.mkdirs();

            // 缓存目录设置
            File imageFile = new File(rootFile.getAbsolutePath() + File.separator + getPermanentSettingAsStr("com_m_common_image","images"));
            if (!imageFile.exists())
                imageFile.mkdirs();
        }*/

	}

	/**
	 * 添加设置配置数据
	 * 
	 * @param settingsXmlName
	 */
	public static void addSettings(String settingsXmlName) {
		Map<String,Setting> newSettingMap = SettingsXmlParser.parseSettings(GlobalContext.getInstance(),settingsXmlName);

		Set<String> keySet = newSettingMap.keySet();
		for (String key : keySet)
			settingMap.put(key,newSettingMap.get(key));
	}

	public static boolean getBooleanSetting(String type) {
		if (settingMap.containsKey(type))
			return Boolean.parseBoolean(settingMap.get(type).getValue());

		return false;
	}

	public static int getIntSetting(String type) {
		if (settingMap.containsKey(type))
			return Integer.parseInt(settingMap.get(type).getValue());

		return -1;
	}

	public static String getStringSetting(String type) {
		if (settingMap.containsKey(type))
			return settingMap.get(type).getValue();

		return null;
	}

	public static Setting getSetting(String type) {
		if (settingMap.containsKey(type))
			return settingMap.get(type);

		return null;
	}

1、放在res下的raw的xml资源文件 setting.xml

<?xml version="1.0" encoding="UTF-8"?>
<app-settings>

	<setting-array type="root_path" index="0">
		<des>应用程序相对sdcard的相对路径目录，所有的文件都存储在这个文件夹中</des>

    </setting>

    <setting type="weico_callback">
        <value>http://oauth.weico.cc</value>
    </setting>

</app-settings>

2、解析成的实体bean，SettingBean，Setting，SettingArray，SettingExtras

class SettingBean implements Serializable {

	private static final long serialVersionUID = -3694407301270573142L;

	private String description;

	private String type;

	private String value;

	public String getDescription() {
		return description;
	}

	public void setDescription(String description) {
		this.description = description;
	}

	public String getType() {
		return type;
	}

	public void setType(String type) {
		this.type = type;
	}

	public String getValue() {
		return value;
	}

	public void setValue(String value) {
		this.value = value;
	}
}

public class Setting extends SettingBean implements Serializable {

	private static final long serialVersionUID = 4801654811733634325L;
	
	private Map<String,SettingExtra> extras;

	public Setting() {
		extras = new HashMap<String,SettingExtra>();
	}

	public Map<String,SettingExtra> getExtras() {
		return extras;
	}

	public void setExtras(Map<String,SettingExtra> extras) {
		this.extras = extras;
	}
	
}

public class SettingArray extends SettingBean implements Serializable {

	private static final long serialVersionUID = 6482515166206579219L;

	private List<Setting> settingArray;

	private int index;
	
	public SettingArray() {
		settingArray = new ArrayList<Setting>();
	}

	public List<Setting> getSettingArray() {
		return settingArray;
	}

	public void setSettingArray(List<Setting> settingArray) {
		this.settingArray = settingArray;
	}

	public int getIndex() {
		return index;
	}

	public void setIndex(int index) {
		this.index = index;
	}
}

public class SettingExtra extends SettingBean implements Serializable {

	private static final long serialVersionUID = 4608815242740722900L;

}

3、解析的方法，返回的是一个map集合

static Map<String,Setting> parseSettings(Context context,String fileName) {
		Map<String,Setting> settingMap = new HashMap<String,Setting>();
		List<SettingArray> settingArray = new ArrayList<SettingArray>();
		List<SettingExtra> settingExtras = null;

		Setting readSetting = null;
		SettingArray readSettingArray = null;
		SettingExtra readSettingExtra = null;

		XmlPullParser xmlResParser = null;
		try {
			String packageName = context.getPackageName();
			Resources resources = context.getPackageManager().getResourcesForApplication(packageName);

			Logger.d("read xml resource,filename = " + fileName);

			int resId = resources.getIdentifier(fileName,"raw",packageName);

			// 解析URL配置
			xmlResParser = Xml.newPullParser();
			xmlResParser.setInput(resources.openRawResource(resId),"utf-8");
			int eventType = xmlResParser.getEventType();
			while (eventType != XmlPullParser.END_DOCUMENT) {

				switch (eventType) {
				case XmlPullParser.START_TAG:
					if ("setting-array".equals(xmlResParser.getName())) {
						readSettingArray = new SettingArray();
						readSettingArray.setType(xmlResParser.getAttributeValue(null,"type"));
						readSettingArray.setIndex(Integer.parseInt(xmlResParser.getAttributeValue(null,"index")));
					}

					if ("setting".equals(xmlResParser.getName())) {
						readSetting = new Setting();
						readSetting.setType(xmlResParser.getAttributeValue(null,"type"));
					}

					if ("extras".equals(xmlResParser.getName())) {
						settingExtras = new ArrayList<SettingExtra>();
					}

					if ("extra".equals(xmlResParser.getName())) {
						readSettingExtra = new SettingExtra();
						readSettingExtra.setType(xmlResParser.getAttributeValue(null,"type"));
					}

					if ("des".equals(xmlResParser.getName())) {
						if (readSettingExtra != null) {
							readSettingExtra.setDescription(xmlResParser.nextText());
						} else if (readSetting != null) {
							readSetting.setDescription(xmlResParser.nextText());
						} else if (readSettingArray != null) {
							readSettingArray.setDescription(xmlResParser.nextText());
						}
					}

					if ("value".equals(xmlResParser.getName())) {
						if (readSettingExtra != null) {
							readSettingExtra.setValue(xmlResParser.nextText());
						} else if (readSetting != null) {
							readSetting.setValue(xmlResParser.nextText());
						}
					}

					break;
				case XmlPullParser.END_TAG:
					if ("setting".equals(xmlResParser.getName())) {
						if (readSetting != null) {
							if (readSettingArray != null) {
								readSettingArray.getSettingArray().add(readSetting);
							} else {
								settingMap.put(readSetting.getType(),readSetting);
							}
						}
						Logger.d(TAG,String.format("parse new setting --->%s",JSON.toJSONString(readSetting)));
						readSetting = null;
					}

					if ("setting-array".equals(xmlResParser.getName())) {
						settingArray.add(readSettingArray);
						Logger.d(TAG,String.format("parse new settingArray --->%s",JSON.toJSONString(readSettingArray)));
						readSettingArray = null;
					}

					if ("extras".equals(xmlResParser.getName())) {
						if (readSetting != null)
							for (SettingExtra extra : settingExtras)
								readSetting.getExtras().put(extra.getType(),extra);

						settingExtras = null;
					}

					if ("extra".equals(xmlResParser.getName())) {
						settingExtras.add(readSettingExtra);
						Logger.d(TAG,String.format("parse new settingExtra --->%s",JSON.toJSONString(settingExtras)));
						readSettingExtra = null;
					}
				}

				eventType = xmlResParser.next();
			}
		} catch (Exception e) {
			e.printStackTrace();
		} finally {
//			if (xmlResParser != null)
//				xmlResParser.close();
		}

		for (SettingArray array : settingArray) {
			if (array.getSettingArray().size() > array.getIndex()) {
				Setting setting = array.getSettingArray().get(array.getIndex());
				setting.setType(array.getType());
				settingMap.put(setting.getType(),setting);
			}
		}

		return settingMap;
	}
