我想把文本以粗体显示:

@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;
        }
    }
