android-animation - 如何沿 x 轴旋转 View

Question

我想沿其 x 轴旋转 View 。我尝试执行以下操作:

AnimationSet anim=new AnimationSet(true);
RotateAnimation rotate=new      RotateAnimation(0.0f,-10.0f,RotateAnimation.ABSOLUTE,0.5f,RotateAnimation.RELATIVE_TO_SELF,0.5f);
rotate.setFillAfter(true);
rotate.setDuration(5000);
rotate.setRepeatCount(0);
anim.addAnimation(rotate);
View relatv1=(View)findViewById(R.id.relativeLayout1);
relatv1.setAnimation(anim);

但我相反， View 沿其 y 轴旋转。我怎样才能完成 x 轴旋转？

Answer 1

像这样使用 ObjectAnimator:

    ObjectAnimator animation = ObjectAnimator.ofFloat(view, "rotationX", 0.0f, 360f);
    animation.setDuration(5000);
    animation.setRepeatCount(ObjectAnimator.INFINITE);
    animation.setInterpolator(new AccelerateDecelerateInterpolator());
    animation.start();
