利用SAX读取写了代码，调试了一下午却一直在parse里抛异常。尼玛，Java的库函数还真心不怎么好用。

把代码贴上来先：

package com.example.gulanfinddemo;import java.io.IOException;import javax.xml.parsers.ParserConfigurationException;import org.xml.sax.SAXException;import android.app.Activity;import android.content.Intent;import android.os.Bundle;import android.util.Log;import android.view.View;import android.widget.ArrayAdapter;import android.widget.Spinner;public class MainActivity extends Activity {	private Spinner suraIDpinner;	private QuranXmlParser quranXmlParser;		final public static String ExtraStr = "FindRes";		private static final String[] m={"1","2","3","4","5"}; 	private ArrayAdapter
     
       adapter; 		@Override	protected void onCreate(Bundle savedInstanceState) {		super.onCreate(savedInstanceState);		setContentView(R.layout.activity_main);				quranXmlParser = new QuranXmlParser();				 Log.v("MainActivity", "1");		 		try {			quranXmlParser.ReadXML("GuLan.xml");		} catch (ParserConfigurationException e) {			// TODO Auto-generated catch block			e.printStackTrace();		} catch (SAXException e) {			// TODO Auto-generated catch block			e.printStackTrace();		} catch (IOException e) {			// TODO Auto-generated catch block			e.printStackTrace();		}				InitSuraIDSpinner();				suraIDpinner.setPrompt("请输入将要查询的章树");                          //设置下拉列表的风格          adapter = new ArrayAdapter
      
       (this, android.R.layout.simple_spinner_dropdown_item,m);                  adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);                 //将adapter 添加到spinner中          suraIDpinner.setAdapter(adapter);         	}		public void InitSuraIDSpinner(){		suraIDpinner = (Spinner)findViewById(R.id.SuraIDSpinner);	}	public void onClickSuraAyaFindBtn(View view){		 Intent intent = new Intent(this, FindResActivity.class);		 String selectedString = suraIDpinner.getSelectedItem().toString();		 if(null==selectedString){			 selectedString="NoThing";		 }		 intent.putExtra(ExtraStr, selectedString);		 startActivity(intent);	}}
      
     

　　新建一个FindResActivity，显示结果：

package com.example.gulanfinddemo;import android.os.Bundle;import android.app.Activity;import android.content.Intent;import android.view.Menu;import android.widget.TextView;public class FindResActivity extends Activity {	@Override	protected void onCreate(Bundle savedInstanceState) {		super.onCreate(savedInstanceState);		setContentView(R.layout.activity_find_res);				Intent intent = getIntent();		String findReString = intent.getStringExtra(MainActivity.ExtraStr);				TextView resText = (TextView)findViewById(R.id.ResText);		resText.setText(findReString);	}	}

　　一个QuranXmlParser类：

package com.example.gulanfinddemo;import java.io.IOException;import java.io.StringReader;import java.util.HashMap;import java.util.Map;import javax.xml.parsers.ParserConfigurationException;import javax.xml.parsers.SAXParser;import javax.xml.parsers.SAXParserFactory;import org.xml.sax.InputSource;import org.xml.sax.SAXException;import org.xml.sax.XMLReader;import org.xml.sax.helpers.DefaultHandler;import android.util.Log;public class QuranXmlParser{private String m_res;private volatile boolean m_isDoFind;public QuranXmlParser(){	m_isDoFind=false;}public boolean ReadXML(String xmlString) throws ParserConfigurationException, SAXException, IOException{	Log.v("ReadXML", "1");		XMLHandler handler = new XMLHandler();	     SAXParserFactory factory = SAXParserFactory.newInstance();    SAXParser parser = factory.newSAXParser();    parser.parse(xmlString,handler);        Log.v("ReadXML", "2");	return true;}}

　　新建一个XMLHandler，负责具体的读取XML：

package com.example.gulanfinddemo;import java.io.IOException;import java.io.StringReader;import java.util.HashMap;import java.util.Map;import java.util.jar.Attributes;import javax.xml.parsers.ParserConfigurationException;import javax.xml.parsers.SAXParser;import javax.xml.parsers.SAXParserFactory;import org.xml.sax.InputSource;import org.xml.sax.SAXException;import org.xml.sax.XMLReader;import org.xml.sax.helpers.DefaultHandler;import android.R.integer;import android.util.Log;import android.util.Pair;public class XMLHandler extends DefaultHandler{		public static String tag = "XMLHandler";	final int quran = 0;    final int suraID = 1;    final int suraName = 2;    final int aya = 3;    final int qurantext = 4;    int currentState = 0;    String suraIDString;    String suraNameString;    String ayaID;        private HashMap
     
       m_AyaContentMap;    private Map
      
        m_SuarIDSet;    private HashMap
       
         m_Id2IDsHashMap;        public HashMap
        
          getAyaContentMap(){    	return m_AyaContentMap;    }        public Map
         
           getSuarIDSet(){    	return m_SuarIDSet;    }        public HashMap
          
            getId2IDsHashMap(){ return m_Id2IDsHashMap; } public void startElement(String namespacesURI , String localName , String qName , Attributes atts) throws SAXException{ if(localName.equals("sura")){ if(qName.equals("suraID")){ currentState = suraID; } else if(qName.equals("suraName")){ currentState = suraName; } } else if(localName.equals("aya")){ currentState = aya; } else if (localName.equals("qurantext")){ currentState = qurantext; } else if(localName.equals("quran")){ currentState = quran; } } public void endElement(String namespacesURI , String localName , String qName) throws SAXException{ } public void characters(char[] ch , int start , int length) throws SAXException{ String theString = new String(ch, start, length); if(null != theString){ } switch(currentState){ case suraID:{ suraIDString = theString; } break; case suraName:{ suraNameString = theString; m_SuarIDSet.put(suraIDString, suraNameString); } case aya:{ ayaID = theString; } break; case qurantext:{ m_Id2IDsHashMap.put(suraIDString,ayaID); final String keyString = suraIDString+":"+ayaID; m_AyaContentMap.put(keyString, theString); Log.v(tag,keyString+" "+theString); } break; } }}
          
         
        
       
      
     

　　然后主窗口布局：

　　显示结果窗口布局：

　主窗口显示：
