我正在使用rotate animation(xml)旋转ImageView。我已将其设置为旋转360度然后再旋转回0度。它仅旋转到270度然后返回0。请您解释一下原因背后

rotate.xml:

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
    android:fillAfter="true"

    >
    <rotate
        android:interpolator="@android:anim/accelerate_decelerate_interpolator"
        android:duration="1000"
        android:fromDegrees="0"
        android:toDegrees="360"
        android:pivotY="50%"
        android:pivotX="50%"
        >
    </rotate>
    <rotate
        android:interpolator="@android:anim/accelerate_decelerate_interpolator"
        android:duration="300"
        android:fromDegrees="360"
        android:toDegrees="0"
        android:pivotY="50%"
        android:pivotX="50%"
        >
    </rotate>
</set>

代码:

Animation animation1=AnimationUtils.loadAnimation(getApplicationContext(),R.anim.rotate);
        imageView.setAnimation(animation1);
        imageView.startAnimation(animation1);

在Java中使用

imageView.animate().rotation(360).setDuration(1000).withEndAction(new Runnable() {
        @Override
        public void run() {
           btnSingup.animate().rotation(0).setDuration(300);
        }
    });
