我想用一些点创建一个动画，它们从上到下落下。为此，我使用的是平移动画，可以将点图像从上到下移动。但我希望这是连续的，这意味着动画应该重演。
我必须创建一个带有一些点的动画，它们从上到下掉落我将发布gif动画文件，这是我的要求，请任何人指导我如何创建这个？ 它从FadeIn动画开始，它在我的代码中正常运行，然后从TOP到BOTTOM以连续动态移动的点，如我发布的gif我在我的代码中没有工作我创建了14个Linearlayouts它们包含7个texviews水平带有可见性。在Oncreate中我已经将其可见性改为VISIBLE并开始FADE IN动画，我将发布我的代码，请有人指导我吗？ 我的要求 rain_like_animation
