尝试编写一个hello world CLDC黑莓程序

发布于 2024-11-03 01:34:13 字数 751 浏览 5 评论 0原文

我得到了《Advanced Black Berry 6 Development》一书。我能够使 midlet 示例正常工作，但不是 CLDC 程序的第一个示例。似乎它永远不会到达代码，当我运行应用程序时，我得到一个空白的白屏。我试图设置一个断点，但它从未消失。

这是代码

package test.org;
import net.rim.device.api.ui.UiApplication;
import net.rim.device.api.ui.component.*;
import net.rim.device.api.ui.container.*;

public class cHelloUniverses extends  UiApplication{


    public static void main(String[] args)
     {
         (new cHelloUniverses()).start();
     }


    public void start()
 {
     MainScreen main = new MainScreen();
     LabelField label= new LabelField("Hello Ted");
     main.add(label);

     UiApplication app = UiApplication.getUiApplication();
     app.pushScreen(main);
     app.enterEventDispatcher();

 }


}

I got the book Advance Black Berry 6 Development.
I was able to get the midlet example to work, but not the first example for a CLDC program. It seems like it never gets to the code and when I run the app I get a blank white screen.
I tried to put a break point but it never went off.

Here is the code

package test.org;
import net.rim.device.api.ui.UiApplication;
import net.rim.device.api.ui.component.*;
import net.rim.device.api.ui.container.*;

public class cHelloUniverses extends  UiApplication{


    public static void main(String[] args)
     {
         (new cHelloUniverses()).start();
     }


    public void start()
 {
     MainScreen main = new MainScreen();
     LabelField label= new LabelField("Hello Ted");
     main.add(label);

     UiApplication app = UiApplication.getUiApplication();
     app.pushScreen(main);
     app.enterEventDispatcher();

 }


}

将 start() 方法替换为：

public void start()
 {
     MainScreen main = new MainScreen();
     LabelField label= new LabelField("Hello Ted");
     main.add(label);

     this.pushScreen(main);
     this.enterEventDispatcher();

 }

Replace your start() method with this:

public void start()
 {
     MainScreen main = new MainScreen();
     LabelField label= new LabelField("Hello Ted");
     main.add(label);

     this.pushScreen(main);
     this.enterEventDispatcher();

 }
