类名称：Views
方法名：rotate

Views.rotate介绍

[英]Create view that is rotated by 90 degrees. The rotation is specified by the fromAxis and toAxis arguments. If fromAxis=0 and toAxis=1, this means that the X-axis of the source view is mapped to the Y-Axis of the rotated view. That is, it corresponds to a 90 degree clock-wise rotation of the source view in the XY plane. fromAxis=1 and toAxis=0 corresponds to a counter-clock-wise rotation in the XY plane.
[中]创建旋转90度的视图。旋转由fromAxis和toAxis参数指定。如果fromAxis=0且toAxis=1，则表示源视图的X轴映射到旋转视图的Y轴。也就是说，它对应于XY平面中源视图的90度顺时针旋转。fromAxis=1和toAxis=0对应于XY平面中的逆时针旋转。
