我需要从服务器解析 XML 文件。有人可以帮帮我吗。
我的代码：
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);
}
}
}
处理程序类：
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();
}
}
