我以一种简单的方式旋转FAB:
I rotate the FAB in such a simple way:
fab.startAnimation(AnimationUtils.loadAnimation(this, R.anim.rotate));rotate.xml :
<?xml version="1.0" encoding="utf-8"?> <set xmlns:android="schemas.android/apk/res/android"> <rotate android:fromDegrees="0" android:toDegrees="360" android:pivotX="50%" android:pivotY="50%" android:duration="1000"/> </set>这可以工作，但是阴影与FAB一起旋转.但是我只需要旋转FAB(如果有任何区别，甚至可以旋转它的src图像).
This works, but together with the FAB its shadow rotates. But I need only the FAB to rotate (or even its src image, if there's any difference).
推荐答案您尝试使用Compat库提供的动画方法吗?使用Animation utils时我也遇到同样的问题
Did you try with the animate method provided by the Compat library? I too had the same problem when using Animation utils
final OvershootInterpolator interpolator = new OvershootInterpolator(); ViewCompat.animate(fab). rotation(135f). withLayer(). setDuration(300). setInterpolator(interpolator). start();
