android - 只能在不持有的情况下执行 ImageView 的旋转

Question

大家好，我用下面的代码进行旋转，但是只旋转了一次就回到了原来的位置，如何让图像停留在旋转后的位置？

 <?xml version="1.0" encoding="utf-8"?>
<rotate
xmlns:android="http://schemas.android.com/apk/res/android"
android:fromDegrees="0"
android:toDegrees="90"
android:pivotX="50%"
android:pivotY="50%"
android:duration="1000"
android:startOffset="0"
/>

我的代码的xml文件

 Animation rotation = AnimationUtils.loadAnimation(this, R.anim.rotate);
    a.startAnimation(rotation);

Answer 1

使用:

anim.setFillAfter(true);

If fillAfter is true, the transformation that this animation performed will persist when it is finished. Defaults to false if not set. Note that this applies to individual animations and when using an AnimationSet to chain animations.
