我想旋轉一個 ImageView。但我想從 0 旋轉到 45 到 -45，然后返回 0 來總結我的目標。我嘗試創建 4rotationAnimation并將它們與AnimatorSet.這是我的代碼： rotate = new RotateAnimation(0, 45, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f); rotate.setDuration(1000); rotate.setInterpolator(new LinearInterpolator()); rotate1 = new RotateAnimation(45, -45, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f); rotate1.setDuration(1000); rotate1.setInterpolator(new LinearInterpolator()); rotate2 = new RotateAnimation(-45, 45, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f); rotate2.setDuration(1000); rotate2.setInterpolator(new LinearInterpolator()); rotate3 = new RotateAnimation(45, 0, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f); rotate3.setDuration(1000); rotate3.setInterpolator(new LinearInterpolator()); setAnim= new AnimationSet(true); setAnim.addAnimation(rotate); setAnim.addAnimation(rotate1); setAnim.addAnimation(rotate2); setAnim.addAnimation(rotate3);img.startAnimation(setAnim);目前圖像突然沒有旋轉到 45° 并返回到 0°。

您可以使用AnimationListener
例子
yourFirstAnim.setAnimationListener(new AnimationListener() {
@Override
public void onAnimationStart(Animation animation) {
}
@Override
public void onAnimationRepeat(Animation animation) {
}
@Override
public void onAnimationEnd(Animation animation) {
doYourNextAnim()
}
});
或者更簡單的方法，使用AnimatorSet()
AnimatorSet as = new AnimatorSet();
as.playSequentially(yourFirstAnim,
yourSecondAnim,
..,
...);
as.setDuration(YOUR_DURATION);
as.start();
更新 為了避免回調地獄，我們可以使用StartDelay
imgAvatar1.animate()
.alpha(1f)
.setDuration(YOUR_DURATION)
.start()
imgAvatar2.animate()
.alpha(1f)
.setStartDelay(YOUR_DURATION * 1)
.setDuration(YOUR_DURATION)
.start()
imgAvatar3.animate()
.alpha(1f)
.setStartDelay(YOUR_DURATION * 2)
.setDuration(YOUR_DURATION)
.start()

您正在使用您的AnimationSet().
問題可能出在參數上fillAfter。
setFillAfter(true)在你的動畫上使用rotate，所以動畫參數在動畫之后應用。
