解析使用XML android系統解析描述的細節，我想所有文字，顯示粗體字母

我的編碼

@Override 
    public void startElement(String uri, String localName, String qName,Attributes attributes) throws SAXException 
    { 
     printParseInfo("startElement:", uri, localName, qName); 
     int attributesLength = attributes.getLength(); 
     for (int i = 0; i < attributesLength; i++) 
     { 
      printAttributeInfo(attributes, i); 
     } 
     currentElement = true; 
     if (localName.equals("rss")) 
     { 
      /** Start */ 
      sitesList = new SitesList(); 
     } 
    } 
    /** Called when tag closing (ex:- <name>AndroidPeople</name> -- </name>)*/ 
    @Override 
    public void endElement(String uri, String localName, String qName) throws SAXException 
    { 
     currentElement = false; 
     printParseInfo("endElement: ", uri, localName, qName); 
     /** set value */ 
     if (localName.equalsIgnoreCase("title")) 
     { 
      //Log.d("title--->",currentValue); 
      sitesList.setTitle(currentValue); 
     } 
     else 
     if(localName.equalsIgnoreCase("span")) 
     { 
      //Log.d("strong-->",currentValue); 
      sitesList.setStrong(currentValue); 
     } 
     if (localName.equalsIgnoreCase("description")) 
     { 
      //Log.d("description--->",currentValue); 
      sitesList.setDescription(currentValue); 
     } 
     else 
     if (localName.equalsIgnoreCase("author")) 
     { 
      //Log.d("Author--->",currentValue); 
      sitesList.setAuthor(currentValue); 
     } 
     else 
     if(localName.equalsIgnoreCase("pubDate")) 
     { 
      //Log.d("pubDate--->",currentValue); 
      sitesList.setPubDate(currentValue); 
     } 
     else 
     if(localName.equalsIgnoreCase("image")) 
     { 
      //Log.d("Image--->",currentValue); 
      sitesList.setImage(currentValue); 
     } 
    } 
    /** Called to get tag characters (ex:- <name>AndroidPeople</name> -- to get AndroidPeople Character) */ 
    @Override 
    public void characters(char[] ch, int start, int length) throws SAXException 
    { 
     if (currentElement) 
     { 
      currentValue = new String(ch, start, length); 
      Log.d("char-->",currentValue); 
      currentElement = false; 
     } 
    }
