如何写一个可以永远无限旋转的imageview控件

1、首先写动画animation1.xml的xml文件

<?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="55555"
    android:fillAfter="true"
    android:repeatCount="infinite"
    android:interpolator="@android:anim/linear_interpolator">
</rotate>

2.在java文件中像下面这样调用即可

        ImageView imageView = (ImageView)findViewById(R.id.picture);
        Animation animation = AnimationUtils.loadAnimation(Mainactivity.this, R.anim.animation1);
        imageView.startAnimation(animation);
