问题描述

谁能给我一个完整的系列教程链接或样本Eclipse项目code链接的XML在Android的SAX解析后显示在列表视图中的数据。

Can anyone give me a full tutorial series Link or sample eclipse project code Link for displaying data in list view after SAX Parsing of XML in Android.

在此先感谢。

推荐答案

下面试试这个

在活动中，您希望在ListView是在：

In the activity you want the listView to be in:

public class listView extends ListActivity {
    ArrayList<String> items = new ArrayList<String>();

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.listViewLayout);
        try {
            /** Handling XML */
            SAXParserFactory spf = SAXParserFactory.newInstance();
            SAXParser sp = spf.newSAXParser();
            XMLReader xr = sp.getXMLReader();

            /** If using remote server for xml file */
            URL sourceUrl = new URL("http://www.server.com/fileToParse.xml");

            /** Create handler to handle XML Tags ( extends DefaultHandler ) */
            ExampleHandler myXMLHandler = new ExampleHandler();
            xr.setContentHandler(myXMLHandler);
            /** if using remote file */
            xr.parse(new InputSource(sourceUrl.openStream()));
            /** if local file */
            xr.parse(new InputSource(getContext().getResources().getXml(R.fileToParse.MyXml));
        }catch(Exception e) {
            Log.e("XML Error "+e.toString());
        }

        /** Get result from MyXMLHandler SitlesList Object */
        sitesList = ExampleHandler.sitesList;
        for(int i = 0; i < sitesList.getName().size(); i++) {
            items.add(sitesList.getName().get(i)+" "+sitesList.getLastName().get(i));
        }

        /** Set the layout view to display */
        setListAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, items));
    }

    public void onListItemClick(ListView parent, View v, int position, long id) {
        /** puExtra method for if you want to pass variable to next activity */
        Intent i = new Intent(this, listViewSub.class);
        i.putExtra("name", sitesList.getName());
        startActivity(i);
    }
}

listViewLayout.xml： 无法获取布局文件显示所以点击这里

listViewLayout.xml: Can't get layout file to show so click here

ExampleHandler.java：

ExampleHandler.java:

public class ExampleHandler extends DefaultHandler{

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

    public static SitesList getSitesList() {
    return sitesList;
    }

    public static void setSitesList(SitesList sitesList) {
    ExampleHandler.sitesList = sitesList;
    }

    /** Called when tag starts ( ex:- <name>AndroidPeople</name>
    * -- <name> )*/
    @Override
    public void startElement(String uri, String localName, String qName,
    Attributes attributes) throws SAXException {

    currentElement = true;

    if (localName.equals("Records"))
    {
    /** 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;

    /** set value */
    if (localName.equalsIgnoreCase("FirstName"))
    sitesList.setName(currentValue);
    else if(localName.equalsIgnoreCase("LastName"))
    sitesList.setLastName(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);
    currentElement = false;
    }

    }
}

SitesList.java：

SitesList.java:

public class SitesList {

/** Variables */
private ArrayList<String> name = new ArrayList<String>();
private ArrayList<String> lastName = new ArrayList<String>();

/** In Setter method default it will return arraylist
* change that to add */

public ArrayList<String> getName() {
return name;
}

public void setName(String name) {
this.name.add(name);
}

public void setLastName(String lastName) {
    this.lastName.add(lastName);
}

public ArrayList<String> getLastName() {
    return lastName;
}

}

fileToParse.xml：点击查看XML文件
