也许，这样做会有帮助:

Runnable runnable = new Runnable() {
    @Override
    public void run() {
        imageView.animate().rotationBy(360).withEndAction(this).setDuration(3000).setInterpolator(new LinearInterpolator()).start();
    }
};

imageView.animate().rotationBy(360).withEndAction(runnable).setDuration(3000).setInterpolator(new LinearInterpolator()).start();

顺便说一下，你可以像这样旋转360度以上:

imageView.animate().rotationBy(10000)...

修剪包裹<rotate>-Element的<set>-Element可以解决这个问题!

感谢沙拉菲!

所以你的Rotation_ccw.xml应该是这样的:

<?xml version="1.0" encoding="utf-8"?>

<rotate
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:fromDegrees="0"
    android:toDegrees="-360"
    android:pivotX="50%"
    android:pivotY="50%"
    android:duration="2000"
    android:fillAfter="false"
    android:startOffset="0"
    android:repeatCount="infinite"
    android:interpolator="@android:anim/linear_interpolator"
    />

我也有这个问题，并试图在xml中设置线性插值器，但没有成功。对我来说有效的解决方案是在代码中创建一个RotateAnimation动画。

RotateAnimation rotate = new RotateAnimation(0, 180, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f);
rotate.setDuration(5000);
rotate.setInterpolator(new LinearInterpolator());

ImageView image= (ImageView) findViewById(R.id.imageView);

image.startAnimation(rotate);

如果你像我一样使用set Animation，你应该在set标签内添加插值:

<set xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="@android:anim/linear_interpolator">

 <rotate
    android:duration="5000"
    android:fromDegrees="0"
    android:pivotX="50%"
    android:pivotY="50%"
    android:repeatCount="infinite"
    android:startOffset="0"
    android:toDegrees="360" />

 <alpha
    android:duration="200"
    android:fromAlpha="0.7"
    android:repeatCount="infinite"
    android:repeatMode="reverse"
    android:toAlpha="1.0" />

</set>

这对我很管用。

在芬兰湾的科特林:

 ivBall.setOnClickListener(View.OnClickListener {

            //Animate using XML
            // val rotateAnimation = AnimationUtils.loadAnimation(activity, R.anim.rotate_indefinitely)

            //OR using Code
            val rotateAnimation = RotateAnimation(
                    0f, 359f,
                    Animation.RELATIVE_TO_SELF, 0.5f,
                    Animation.RELATIVE_TO_SELF, 0.5f

            )
            rotateAnimation.duration = 300
            rotateAnimation.repeatCount = 2

            //Either way you can add Listener like this
            rotateAnimation.setAnimationListener(object : Animation.AnimationListener {

                override fun onAnimationStart(animation: Animation?) {
                }

                override fun onAnimationRepeat(animation: Animation?) {
                }

                override fun onAnimationEnd(animation: Animation?) {

                    val rand = Random()
                    val ballHit = rand.nextInt(50) + 1
                    Toast.makeText(context, "ballHit : " + ballHit, Toast.LENGTH_SHORT).show()
                }
            })

            ivBall.startAnimation(rotateAnimation)
        })

100%正确的答案

var rotate =旋转动画( 0 f,华氏360度, 动画。RELATIVE_TO_SELF, 0.5度, 动画。RELATIVE_TO_SELF, 0.5度 ) 旋转。持续时间= 999 旋转。repeatCount =动画。无限 imageview . . setAnimation(旋转)

100%的工作! !
