解析XML联机文件Android

问题描述：

我正在为Android创建应用程序，我需要显示此页面的XML文件：http://www.bovalpo.com/cgi-local/xml_bcv.pl?URL=7009 我尝试了页面上给出的解决方案，但是我发现它是错误的，因为它在运行时不显示应用程序。我只是想表明 “TIPO = DOLAR SPOT INTERCAMBIO”解析XML联机文件Android

这是XML代码

XML CODE

，这是我的代码：

xmlpruebaprueba.jar

XMLdataCollected sitesList= null; 

@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_xmlpruebaprueba); 


    //creando un Layout 
    LinearLayout layout = new LinearLayout(this); 
    layout.setOrientation(1); 

    //creando TextView 

    TextView Registro[]; 
    TextView Tipo[]; 

    try { 
     SAXParserFactory spf = SAXParserFactory.newInstance(); 
     SAXParser sp = spf.newSAXParser(); 
     XMLReader xr = sp.getXMLReader(); 

     URL sourceURL = new URL("http://www.bovalpo.com/cgi-local/xml_bcv.pl?URL=7009"); 

     handlingXml HandlingXml = new handlingXml(); 
     xr.setContentHandler(HandlingXml); 
     xr.parse(new InputSource(sourceURL.openStream())); 
    }catch (Exception e){ 
     System.out.println("XML Parsing Exception= " + e); 
    } 


    sitesList = handlingXml.sitesList; 

    Registro = new TextView[sitesList.getRegistro().size()]; 
    Tipo = new TextView[sitesList.getTipo().size()]; 

    for (int i = 0; i < sitesList.getRegistro().size(); i++) { 
     Registro[i] = new TextView(this); 
     Registro[i].setText("Registro = "+sitesList.getRegistro().get(i)); 
     Tipo[i] = new TextView(this); 
     Tipo[i].setText("Tipo = "+sitesList.getTipo().get(i)); 

     layout.addView(Registro[i]); 
     layout.addView(Tipo[i]); 
    } 
}

}

，这是我的处理程序

Boolean currentElement = false; 
String currentValue = null; 
public static XMLdataCollected sitesList = null; 


public static XMLdataCollected getDataCollected(){ 
    return sitesList; 
} 

public static void setSitesList(XMLdataCollected sitesList){ 
    handlingXml.sitesList = sitesList; 
} 

@Override 
public void startElement(String uri, String localName, String qName, 
     Attributes attributes) throws SAXException { 
    // TODO Auto-generated method stub 

    currentElement = true; 

    if(localName.equals("Root")) 
    { 
     sitesList = new XMLdataCollected(); 
    }else if (localName.equals("Registro")){ 
     String attr = attributes.getValue("tipo"); 
     sitesList.setTipo(attr); 
    } 
} 



@Override 
public void endElement(String uri, String localName, String qName) 
     throws SAXException { 
    // TODO Auto-generated method stub 

    currentElement = false; 


    if (localName.equalsIgnoreCase("Registro")) 
     sitesList.setRegistro(currentValue); 
     else if (localName.equalsIgnoreCase("Root")) 
     sitesList.setRoot(currentValue);  
    } 

@Override 
public void characters(char[] ch, int start, int length) 
     throws SAXException { 
    // TODO Auto-generated method stub 
    if (currentElement) { 
     currentValue = new String(ch, start, length); 
     currentElement = false; 
     } 
} 

}

，这是我dataCollected

公共类XMLdataCollected {

private ArrayList<String> root = new ArrayList<String>(); 
private ArrayList<String> registro = new ArrayList<String>(); 
private ArrayList<String> tipo = new ArrayList<String>(); 

public ArrayList<String> getRoot(){ 
    return root; 
} 

public void setRoot(String root){ 
    this.root.add(root); 
} 

public ArrayList<String> getRegistro(){ 
    return registro; 
} 

public void setRegistro(String registro){ 
    this.registro.add(registro); 
} 

public ArrayList<String> getTipo(){ 
    return tipo; 
} 

public void setTipo(String tipo){ 
    this.tipo.add(tipo); 
}

}

应用程序崩溃？或什么也没有显示 – 2012-07-18 18:18:32

显示错误消息并关闭应用程序 – 2012-07-18 18:20:00

然后他们是一个崩溃日志..在你的'LogCat'中。发布它..btw问题是..你正在主UI线程上运行'网络请求'..使用AsyncTask调用Web请求。 http://developer.android.com/reference/android/os/AsyncTask.html – 2012-07-18 18:23:03

答

您是在主呼唤你的Web Request UI线程。

请不要做这个

使用AsyncTask调用的Web请求。
