图像不显示在midlet
问题描述:
这里是新的。我有一个小问题;看看下面的代码,并告诉我如果我做错了什么,因为图像不显示。我已经使它非常小,所以它应该适合,但它不显示。我有其他屏幕显示的图像,但这个主midlet不会。这里是代码:图像不显示在midlet
import java.io.IOException;
import javax.microedition.midlet.*;
import javax.microedition.lcdui.*;
/**

public class WShop extends MIDlet implements CommandListener {
/* Declare display variables*/
private Form mainForm;
private Display display;
private Command OK,Exit,wView, mView, myView;
/* */
Categories categories = new Categories(this);
Image image;
public WShop() {
/* initialize Screen and Command buttons that will
be used when the application starts in the class constructor*/
mainForm = new Form("Wind Shopper");
OK = new Command("OK", Command.OK, 2);
Exit = new Command("Exit", Command.EXIT, 0);
wview= new Command("wview", Command.OK, 0);
mview= new Command("mview", Command.OK, 0);
try {
/* retrieving the main image of the application*/
image = Image.createImage("/main.png");
} catch (IOException ex) {
ex.printStackTrace();
}
mainForm.addCommand(OK);
mainForm.addCommand(Exit);
mainForm.addCommand(wView);
mainForm.addCommand(mView);
mainForm.setCommandListener(this);
}
public void startApp() {
/* checks to see if the display is currently empty
and then sets it to the current screen */
if (display == null) {
display = Display.getDisplay(this);
}
display.setCurrent(mainForm);
}
/* paused state of the application*/
public void pauseApp() {
}
/* Destroy Midlet state*/
public void destroyApp(boolean unconditional) {
}
在此先感谢。
答
在我看来,你忘了Form.append()
您的图片到您的表格。
我感到非常愚蠢和惭愧,我不能相信我忘了这样做,我一直在看它。非常感谢你。 – irobotxxx 2010-04-15 12:03:57
