翻译动画的帮助不大
嘿! 基本上,我有这个文本的小动画,当人们单击屏幕时,它会“滑动”下来。
从上滑到下需要6秒。
当它滑动时,如果有人再次单击屏幕,我想将该动画替换为另一个动画,使其向左/向右或任何不同的方向移动。 基本上,从该位置(而不是从头开始)将translate.xml 动画替换为some_other_animation.xml。
(我最终的想法是让它“爆炸”)。 任何帮助表示赞赏。

Hey!
Basically, I have this little animation of this text that "slides" down when a person clicks the screen.
It takes 6 seconds to slide from top to the bottom.
While it is sliding if someone clicks the screen again, I want to replace that animation with another animation which makes it go left/right or anything different.
Basically, replace the translate.xml animation with some_other_animation.xml right from that spot (not from the beginning).
(My eventual idea is to make it "explode").
Any help appreciated.

嗯,你的“第二个”动画不能用 xml 定义,因为它依赖于运行时事件。您可以根据触摸事件的位置在代码中构造一个新的动画。
Um, your "second" animation cannot be defined with xml, since it depends on a runtime event. You could construct a new animation in code, based on the location of the touch event.
