Arrays 来自数组的JAVAFX文本动画
这是一个正在进行的工作,所以我为我的代码需要清理表示歉意,但我认为最好包括到目前为止的所有内容 我试图通过循环一系列图像来演示如何为文本设置动画。我的代码在数组中循环,只显示最后一幅图像。我需要一次显示一个图像,并重复显示以获得所需的动画效果。我做错了什么或没有做什么Arrays 来自数组的JAVAFX文本动画,arrays,image,loops,animation,javafx,Arrays,Image,Loops,Animation,Javafx,这是一个正在进行的工作,所以我为我的代码需要清理表示歉意,但我认为最好包括到目前为止的所有内容 我试图通过循环一系列图像来演示如何为文本设置动画。我的代码在数组中循环,只显示最后一幅图像。我需要一次显示一个图像,并重复显示以获得所需的动画效果。我做错了什么或没有做什么 import javafx.animation.Timeline; import javafx.application.Application; import javafx.scene.Scene; import javafx.s

非常感谢您的帮助。这是一个应用程序,演示了如何将图像添加到ArrayList中。类似的方法用于阵列。它还演示了如何将这些图像加载到ImageView中,并使用Timeline更改它们 主要 FXML 控制器 输出:如下所示
这到底是怎么回事?动画不做任何事情-它只是在5秒时有一个空的关键帧。如果你想一个接一个地显示图像,为什么要将它们全部添加到网格窗格?如果你只在单元格0,0中添加了子元素,为什么还要使用网格窗格?从一开始就提供最少的代码,而不是要求道歉这不是最小的。
