config.xml文件如下：

<config><br /> <string-array name = "system_app_ti60"><br /> <item>Browser.apk</item><br /> <item>Phone.apk</item><br /> <item>Contact.apk</item><br /> <item>Settings.apk</item><br /> <item>Gmail.apk</item><br /> </string-array><br /> </config>

用到的几个主要的类：

import org.xml.sax.Attributes;  
import org.xml.sax.SAXException;  
import org.xml.sax.helpers.DefaultHandler;
import javax.xml.parsers.SAXParserFactory;
import javax.xml.parsers.SAXParser;
import javax.xml.parsers.ParserConfigurationException;

XmlParser类：主要用于处理读取到的数据，如标签，文本等信息。

private class XmlParser extends DefaultHandler<br /> {<br /> private ArrayList<String> array = new ArrayList<String>();<br /> String mName = null;<br /> private boolean mFound = false;</p> <p> public ArrayList<String> getArrayString(){<br /> return array;<br /> }<br /> //读取到开始标签信息时回调<br /> @Override<br /> public void startElement(String uri, String localName, String qName, Attributes attributes) throws SAXException{<br /> if(localName.equals("string-array")){<br /> mName = attributes.getValue(0);<br /> if(mName.equals("system_app_ti60")){<br /> mFound = true;<br /> }</p> <p> }<br /> }<br /> //读取到文本信息时回调<br /> @Override<br /> public void characters(char ch [ ], int start, int length) throws SAXException{<br /> if(mFound){<br /> String value = new String(ch,start,length);<br /> if(!value.endsWith("apk"))<br /> return;<br /> array.add(value);<br /> }<br /> }<br /> //读取到结束标签信息时回调<br /> @Override<br /> public void endElement(String uri, String localName, String qName) throws SAXException{<br /> if(localName.equals("string-array")){<br /> if(mFound){<br /> mFound = false;<br /> }</p> <p> }<br /> }<br /> }

调用测试：

try{<br /> SAXParserFactory factory = SAXParserFactory.newInstance();<br /> SAXParser parser = factory.newSAXParser();<br /> XmlParser handler = new XmlParser();<br /> parser.parse(new File("/system_extend/system_extend_config.xml"), handler);<br /> AppList = handler.getArrayString();</p> <p> }<br /> catch(SAXException e){<br /> Log.i("hxd","SAXException");<br /> return;<br /> }<br /> catch(ParserConfigurationException e){<br /> Log.i("hxd","ParserConfigurationException");<br /> return;<br /> }<br /> catch(IOException e){<br /> Log.i("hxd","IOException");<br /> return;<br /> }<br /> }
