见程序 :
//文件名 LWTDemoMIDlet.java import com.motorola.lwt.*; import javax.microedition.lcdui.*; import javax.microedition.midlet.*;
public class LWTDemoMIDlet extends MIDlet implements CommandListener { class ButtonScreen extends ComponentScreen {
public ButtonScreen() {
// Add a button to the screen Button b1 = new Button("b"); ///////////下面的代码是设定按钮高度 b1.setBottomEdge(Component.HEIGHT, 30);
///////////下面的代码是设定按钮宽度 b1.setRightEdge(Component.WIDTH,80);
///////////下面的代码是设定按钮y坐标,a相对屏幕最上
b1.setTopEdge(Component.SCREEN_TOP, 10);
///////////下面的代码是设定按钮x坐标相对前一个控件 b1.setLeftEdge(Component.PREVIOUS_COMPONENT_RIGHT, 30);
add(b1);
// Add another button to the screen Button b2 = new Button("点我就行了"){ public void componentActuated() { Show(); } }; // Extend the right edge to the right edge of the screen b2.setRightEdge(Component.WIDTH, 220); b2.setBottomEdge(Component.HEIGHT, b2.getPreferredHeight() * 2); add(b2); Command next = new Command("Next", Command.OK, 1); Command prev = new Command("Previous", Command.BACK, 1);
addCommand(next); addCommand(prev); } };
ButtonScreen screens = new ButtonScreen(); public LWTDemoMIDlet() { screens.setCommandListener(this); } protected void startApp() throws MIDletStateChangeException { Display.getDisplay(this).setCurrent(screens); } protected void pauseApp() { } protected void destroyApp(boolean unconditional) throws MIDletStateChangeException { } public void Show() { System.out.println("Get it on main Class");
} public void commandAction (Command c, Displayable d) {
if (screens == d) { // Found it, check which command was triggered if (c.getCommandType() == Command.BACK) { System.out.println("back"); } else if (c.getCommandType() == Command.OK) { System.out.println("ok"); } return; }
}
}
以上程序用jcreater pro
motoSDK 编译
