用Java制作动画效果

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
