Android中的SAX解析器错误

我需要从服务器解析XML文件。有人可以帮帮我吗。Android中的SAX解析器错误

mycode的：

public class XML2Parser extends Activity { 

TextView antonis1, antonis2, antonis3, tryans1, tryans2, tryans3; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    // TODO Auto-generated method stub 
    super.onCreate(savedInstanceState); 

    setContentView(R.layout.activity_xml2parser); 
    findViewById(); 

    String myurl = "http://www.playhard.cu.cc/tabel.xml"; 
    new XMLParsing().execute(myurl); 
} 

private void findViewById() { 
    // TODO Auto-generated method stub 
    antonis1 = (TextView) findViewById(R.id.tvxml2pantonis1); 
    antonis2 = (TextView) findViewById(R.id.tvxml2pantonis2); 
    antonis3 = (TextView) findViewById(R.id.tvxml2pantonis3); 
    tryans1 = (TextView) findViewById(R.id.tvxml2ptryans1); 
    tryans2 = (TextView) findViewById(R.id.tvxml2ptryans2); 
    tryans3 = (TextView) findViewById(R.id.tvxml2ptryans3);  
} 

public class XMLParsing extends AsyncTask<String,Void,String>{ 

    @Override 
    protected String doInBackground(String...url) { 
     // TODO Auto-generated method stub 
     try { 
      String website = url[0].toString(); 
      URL fullurl = new URL(website); 

      // mengaktifkan parse pada xml reader 
      SAXParserFactory spf = SAXParserFactory.newInstance(); 
      SAXParser sp = spf.newSAXParser(); 
      XMLReader xr = sp.getXMLReader(); 
      XML2ParserHandler Handler = new XML2ParserHandler(); 
      xr.setContentHandler(Handler); 
      InputSource is = new InputSource(fullurl.openStream()); 
      xr.parse(is); 
      String information = Handler.getInfo().toString(); 
      return information; 
     } catch (Exception e) { 
      e.printStackTrace(); 
     } 
     String error = "error"; 
     return error; 
    } 

    @Override 
    protected void onPostExecute(String result) { 
     // TODO Auto-generated method stub 
     antonis1.setText(result); 
    } 
}

}

处理类：

package com.projectx0001.antoni; 

import org.xml.sax.SAXException; 
import org.xml.sax.helpers.DefaultHandler; 

public class XML2ParserHandler extends DefaultHandler{ 

    String testtext; 

    public String getInfo(){ 
     return testtext; 
    } 

    @Override 
    public void startDocument() throws SAXException { 
     // TODO Auto-generated method stub 
     testtext = "It's Work Just Fine!"; 
     super.startDocument(); 
    } 
}

logcat的：

在日志中：

未发现协议：

MalformedURLException的 [Ljava.lang.String; @ 413191b8

，因为目前你正试图转换varags到URL .change

String website = url.toString(); 
    URL fullurl = new URL(website);

到

@Override 
     protected String doInBackground(String...url) { 
      // TODO Auto-generated method stub 
      try { 
       String website = url[0].toString(); 
       URL fullurl = new URL(website); 
       //.....

我已将代码更改为 String website = url [0] .toString（）; URL fullurl = new URL（website）; 但是，尽管括号仍然返回一个异常（返回“错误”），分析器仍然无法正常工作。 – Moonhint
