Rss Feed Reader in j2me using LWUIT not able to display Titles

[pavanragi]

Hii
i want to display rss feed titles and image in a list?in this code i am trying to display rss feed titles on lwuit Form Screen,But when i run my Source Code,i am able to display,only one title,and the loop is stopping?But when i try to do the same code using lcdui list Screen,i am successfully able to display the tittles and image from rss feed url...
//method called by the parsing thread
USING LCDUI LIST AND FORM:
public void addNews(News newsItem) {
news.addElement(newsItem);
myNewsList.append(newsItem.getTitle(), newsItem.getImage());
myDysplay.setCurrent(myNewsList);
}


Here my Sample Code Using LWUIT LIST AND FORM:

//method called by the parsing thread
public void addNews(News newsItem) {

myNewsList.addItem(newsItem.getTitle());
form1.addCommandListener((ActionListener) this);
form1.addComponent(myNewsList);
form1.addCommand(cmdExit);
form1.addCommand(cmdDetails);
form1.setScrollable(true);
form1.setTransitionInAnimator(Transition3D.createRotation(250, true));
form1.show();
Can you check once my Source Code?


}

Hi pavaragi,

LWUIT code looks ok. From the code I can see that only one title( myNewsList.addItem(newsItem.getTitle()) is added. To get more titles add myNewsList.addItem(newsItem.getTitle()); in a loop.

check this code also:
private void ParseXMLFeed(InputStream input)
throws IOException, XmlPullParserException {
Reader dataReader = new InputStreamReader(input);
KXmlParser myParser = null;
try {
myParser = new KXmlParser();
} catch (Exception e) {
//System.out.println("hiiii" + e);
}
myParser.setInput(dataReader);


myParser.nextTag();
myParser.require(XmlPullParser.START_TAG, null, "rss");

myParser.nextTag();
myParser.require(XmlPullParser.START_TAG, null, "channel");
myParser.nextTag();
myParser.require(XmlPullParser.START_TAG, null, "title");

while (myParser.getEventType() != XmlPullParser.END_DOCUMENT) {
String name = myParser.getName();

if (name.equals("channel")) {
break;
}

if (name.equals("item")) {

if (myParser.getEventType() != XmlPullParser.END_TAG) {
myParser.nextTag();
String title = myParser.nextText();
myParser.nextTag();
String link = myParser.nextText();

myParser.nextTag();
String pubDate = myParser.nextText();
myParser.nextTag();

News news = new News(title, link, pubDate, ptext);
System.out.println("gjgjgjgdgdggggggggggg");
parentMidlet.addNews(news); //CHECK OUT HERE ,I AM CALLING THE METHOD
}
} else {

myParser.skipSubTree();
}

myParser.nextTag();
}

input.close();
}

Hii bandarap

i can able to display the second title on out put console:
by :
System.out.println(newsItem.getTitle());
from rss file,but it is failing here(the loop is stopping here)
myNewsList.addItem(newsItem.getTitle());//loop is stopping here

[bandarap]

OK, addNews(news); method is already calling in a while loop, so don't have to create again another loop for myNewsList.addItem(newsItem.getTitle());

public void addNews(News newsItem,Vector nw) {

news.addElement(newsItem);
myNewsList.addItem(newsItem.getTitle());
form1.addComponent(myNewsList);
form1.show()
}

move the following code from addNews() method to the place where Form is instantiated

form1.addCommand(cmdExit);
form1.addCommand(cmdDetails);
form1.setScrollable(true);
form1.setTransitionInAnimator(Transition3D.createRotation(250, true));
form1.addCommandListener((ActionListener) this);

Hii

if declare this in a constructor,facing nullpointer exception and if declare this in a startapp()method,facing the situation like one title display(second title is displaying on my out put console ,but myNewsList.addItem(newsItem.getTitle());//loop is stopping here


public XMLMidlet() {
news = new Vector();
myNewsList = new List();
cmdDetails = new Command("Details");
form1 = new Form("Feeds List");
form1.addCommand(cmdDetails);
form1.setScrollable(true);
form1.setTransitionInAnimator(Transition3D.createRotation(250, true));

}
