Question

我想沿x轴旋转视图。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);

但我改为视图沿y轴旋转。我如何完成x轴旋转？

Answer 1

使用像这样的ObjectAnimator：

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

Answer 2

ObjectAnimator类沿着轴旋转，作为参数传递给ofFloat方法的视图。

如果只想旋转视图一次，请不要设置任何重复计数。

answer from "its-tomweber"工作正常。
