Question

我正在尝试制作一个progressBar，它将以0.1步为单位设置其进度，延迟时间为1000毫秒，直到它“满”为止。

我已经找到了一个解决方法，如何延迟一步，但是无法将其转换为for循环，将以0.1步为单位设置进度，直到进度等于1，因此已满。

我如何修改下面的解决方案来实现这一目标？

让你的任务执行迭代，并按原样更新它的进度：

Task<Void> sleeper = new Task<Void>() {
    @Override
    protected Void call() throws Exception {

        final int numIterations = 10 ;
        for (int i = 0 ; i < numIterations ; i++) {
            updateProgress(i, numIterations);
            try {
                Thread.sleep(1000);
            } catch (InterruptedException e) {
            }
        }
        updateProgress(numIterations, numIterations);
        return null;
    }
};

然后将进度条的进度绑定到任务的进度：

progressBar.progressProperty().bind(sleeper.progressProperty());

如何在进度条中将setProgress延迟0.1步直到满
