用Java画动画很简单，让一个线程自己定时调用自己即可，记得要设置一个退出（结束）条件。
import org.eclipse.swt.SWT;
import org.eclipse.swt.layout.FillLayout;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Shell;
import org.eclipse.swt.widgets.Text;
public class Animation {
final static int DELAY = 500;
public static void main(String[] args) {
final Display display = new Display();
final Shell shell = new Shell(display);
shell.setLayout(new FillLayout());
final Text text = new Text(shell, SWT.BORDER);
text.setText("0");
new Runnable() {
public void run() {
if (shell.isDisposed())
return;
text.setText("" + (Integer.parseInt(text.getText()) + 1));
Display.getDefault().timerExec(DELAY, this);
}
}.run();
shell.pack();
shell.open();
while (!shell.isDisposed()) {
if (!display.readAndDispatch())
display.sleep();
}
display.dispose();
}
}
运行结果：
数字不停增长
