Question

我正在制作一个硬币从左边滚动的动画。

到目前为止，我可以通过RotateAnimation旋转并通过TranslateAnimation进行旋转。

现在我被困在尝试同时运行这两个。

{
    Animation animation = new TranslateAnimation(Animation.RELATIVE_TO_PARENT,-1f,Animation.RELATIVE_TO_PARENT,0,Animation.RELATIVE_TO_PARENT, 0, Animation.RELATIVE_TO_PARENT, 0);
    animation.setDuration(5000);
    setCoinAppear.addAnimation(animation);
}
{
    Animation animation = new RotateAnimation(0, 720, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f);
    animation.setDuration(5000);
    setCoinAppear.addAnimation(animation);
}

如果我同时启动它们，硬币将围绕中心显示会聚的圆周运动。

有关如何完成任务的任何建议吗？

您需要创建一个AnimationSet并将每个动画添加到集合中，如下所示：

AnimationSet rollingIn = new AnimationSet(true);

Animation moving = new TranslateAnimation(Animation.RELATIVE_TO_PARENT,-1f,Animation.RELATIVE_TO_PARENT,0,Animation.RELATIVE_TO_PARENT, 0, Animation.RELATIVE_TO_PARENT, 0);
moving.setDuration(5000);

rollingIn.addAnimation(moving);

Animation rotating = new RotateAnimation(0, 720, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f);
rotating.setDuration(5000);

rollingIn.addAnimation(rotating);

setCoinAppear.startAnimation(rollingIn);

Android动画“滚滚”
