解析用の次のコードがあります
public class XML_Parsing_Sample extends UiApplication{
//creating a member variable for the MainScreen
MainScreen _screen= new MainScreen();
//string variables to store the values of the XML document
String _node,_element;
Connection _connectionthread;
public static void main(String arg[]){
XML_Parsing_Sample application = new XML_Parsing_Sample();
//create a new instance of the application
//and start the application on the event thread
application.enterEventDispatcher();
}
public XML_Parsing_Sample() {
_screen.setTitle("XML Parsing");//setting title
_screen.add(new RichTextField("Requesting....."));
_screen.add(new SeparatorField());
pushScreen(_screen); // creating a screen
//creating a connection thread to run in the background
_connectionthread = new Connection();
_connectionthread.start();//starting the thread operation
}
public void updateField(String node, String element) {
synchronized (UiApplication.getEventLock()) {
String title = "My App";

しかし、このアプリケーションを実行しているとき、シミュレーターはラベル付きの空白の画面を表示していますRequesting..
誰でもこれを行うのを手伝ってもらえますか? 私はbb9900シミュレーターを使用しています。
