问题描述
所以我的问题是,在android中有没有一个有效的方法来使用一些预定义的点来绘制像波形一样的平滑波?
感谢您提前提供任何帮助
解决方案
您可以使用 android.graphics.Path 类构造一组二次或立方贝塞尔样条您的控制点集合之间的曲线。
I am making an app where I need to draw a sine wave between two given points. I have Google'd, and Google'd, and I haven't found anything that I have found suitable. So my question is, is there an efficient way in android to use some pre defined points to draw a smooth wave like form? thank you for any help in advance
解决方案
You can use the android.graphics.Path class to construct a set of quadratic or cubic Bézier spline curves between your set of control points.
