问题描述
我用的是ObjectAnimator API（android.animation.ObjectAnimator）一旦它的点击动画按钮（v是按钮）：
I use the ObjectAnimator API (android.animation.ObjectAnimator) to animate a button once it's clicked (v is the Button):
ObjectAnimator animator = ObjectAnimator.ofFloat(v, "rotationY", 360f);
animator.setDuration(5000);
animator.start();
当我测试这个在模拟器上，它适用于第一次点击（按钮旋转）。但是，当我再次点击该按钮（该片段是不是第一次点击后销毁等），我没有看到任何动画在模拟器（模拟器不是最快的，但是，拥有5秒我应该看到的东西）。
When I test this on the emulator, it works for the first click (button rotates). But when I click the button again (the fragment is not destroyed etc. after the first click), I don't see any animation on the emulator (the emulator isn't the fastest, but with 5 seconds I should see something).
我需要摧毁的第一个动画或者我丢失后/关闭的东西吗？
任何人都不会有提示或可重现此？
Do I need to destroy/close something after the first animation or what am I missing?Does anyone have a hint or can reproduce this?
在此先感谢，
马丁
Thanks in advance,Martin
推荐答案
第二次你会尝试从360.0f动画到360.0f。更改）您的来电ofFloat（为：
The second time you will try to animate from 360.0f to 360.0f. Change your call to ofFloat() to:
ObjectAnimator.ofFloat(v, "rotationY", 0.0f, 360.0f)
