手機 - Blackberry Curve9320 - Java - Hello, world!



1. 開啟Blackberry JDK並選擇JDE


2. File => New


3. File => New


4. Finish


5. 在專案上按滑鼠右鍵(產生一個新的HelloWorld.java檔案)



HelloWorld.java

class HelloWorld extends net.rim.device.api.ui.UiApplication {
    public static void main(String[] args) {
        HelloWorld inst = new HelloWorld();
        inst.enterEventDispatcher();
    }

    public HelloWorld(){
        pushScreen(new HelloWorldScreen());
    }
}

6. 在專案上按滑鼠右鍵(產生一個新的HelloWorldScreen.java檔案)



HelloWorldScreen.java

import net.rim.device.api.ui.*;
import net.rim.device.api.ui.component.*;
import net.rim.device.api.ui.container.*;

class HelloWorldScreen extends MainScreen {
    public HelloWorldScreen(){
        super();

        LabelField title = new LabelField("Hello World Application");
        setTitle(title);

        RichTextField t = new RichTextField("Hello World!");
        add(t);
    }

    public boolean onClose(){
        System.exit(0);
        return true;
    }
}

7. 編譯執行程式:Build => Build All and Run
執行程式時,程式會提示找不到HelloWorld.java檔案的位置,這時只要指到HelloWorld.java檔案存放的位置即可,進入模擬器後,選擇HelloWorld程式執行,如果沒看到安裝的HelloWorld程式,選擇File => Load Blackberry Application or Theme...並載入HelloWorld.cod即可
