Java Android上的动画
我一直在环顾四周,寻找答案,在问任何问题之前,我真的试图深入android编程。我知道这个网站是来帮忙的,但也不是一个多余和懒惰的出口。虽然我是安卓的乞丐,如果你们有时间的话,我需要一些帮助。我看了一个我真的认为会有帮助的问题(URL:),但它最终使我的程序崩溃。我也检查了这一个,这也没有真正让我得到正确的答案,我正在寻找。不幸的是,现在我没有代码,但我尝试从我提供的这两个示例站点复制代码。当我在实际java代码中声明动画对象时,它们都崩溃了 i、 e 我的目标基本上就是让一个五彩纸屑动画从我的屏幕的顶部滚到屏幕的底部。我已经创建了大约8个不同的图像,以创建一个“动画”,但我真的不知道如何在Android本身实现这一点。如果有人能帮我或给我指出正确的方向,我将不胜感激。非常感谢你 试试这个Java Android上的动画,java,android,animation,xhtml,Java,Android,Animation,Xhtml,我一直在环顾四周,寻找答案,在问任何问题之前,我真的试图深入android编程。我知道这个网站是来帮忙的,但也不是一个多余和懒惰的出口。虽然我是安卓的乞丐,如果你们有时间的话,我需要一些帮助。我看了一个我真的认为会有帮助的问题(URL:),但它最终使我的程序崩溃。我也检查了这一个,这也没有真正让我得到正确的答案,我正在寻找。不幸的是,现在我没有代码,但我尝试从我提供的这两个示例站点复制代码。当我在实际java代码中声明动画对象时,它们都崩溃了 i、 e 我的目标基本上就是让一个五彩纸屑动画从我的

对该视图使用objectAnimator,并在该视图中保持x参数不变,同时将y参数更改为0到600或相同的值。希望它能起作用。或者翻译器动画师会做这个把戏,试着保持x1=0 x2=0和y1=0 y2=600。

太棒了,我必须试一试。我假设它基本上只是将动画设置为垂直和水平倾斜滚动?这看起来像我所做的应该工作得很好,如果需要,我可以修改
